Technical Field

The invention relates to the technical field of sewage treatment, in particular to an automatic early warning and sample reserving method and device for standard exceeding pollution discharge.

Background

The water pollution directly threatens the human health, destroys the ecological environment and restricts the sustainable development of economy and society. Nowadays, the causes of the water pollution problem are very extensive, including the discharge of industrial wastewater and domestic sewage. Although the government regulates the sewage discharge activities of enterprises, some enterprises steal industrial wastewater in order to save the cost for treating wastewater. The government is overwhelmed with such unlawful acts because these enterprises often use buried pipes for drainage, and these hidden pipes are difficult to find, and such enterprises have been stolen for more than ten years until they are found to steal, and have caused irreparable losses to the ecological environment and human health; moreover, many of these businesses often lay dark paths in multiple locations to circumvent the detection of law enforcement personnel. As such, the necessary measures to control such contamination are required.

When water pollution accidents are treated, the key is to identify pollution at the first time, quickly know the position and the spread range of an illegal sewage discharge outlet and well perform automatic tracking and positioning. On the whole, in the current sudden pollution incident of China, the efficiency of searching and positioning the accident source is low. In sudden pollution events occurring nationwide in recent years, the search and location time of accident pollution sources is as short as 4-7 days, and more as long as 3-4 weeks, and the time is as long as 2 months (such as the arsenic pollution event of Yanzong ocean in Yunnan of 2008). The long period of accident source investigation prolongs the pollution duration, aggravates the pollution degree, and greatly increases the difficulty and cost of later recovery and treatment.

In order to realize accurate and rapid pollution position positioning of a pollution enterprise, a water body organic pollutant monitoring technology emerging in recent years is adopted in the prior art: fluorescent water quality fingerprint technology. Three-dimensional fluorescence spectroscopy (EEM), one of the main methods of fluorescence analysis, is a spectrum obtained by using the wavelength of emission light and the wavelength of excitation light as horizontal and vertical coordinates and projecting the fluorescence intensity on the plane in the form of contour lines. There are many substances with fluorescence, such as oil, humic acid, protein, surfactant, vitamins, aromatic compounds such as phenols, pesticide residues, etc. which are often present in sewage, and sewage contains many kinds of fluorescent substances, so that the fluorescence spectrum of the sewage can change with the different types and contents of pollutants, and has the characteristic of one-to-one correspondence with the water sample, so that the sewage is called as the water quality 'fluorescence fingerprint'. The specific composition of the pollutant can be accurately known by the fluorescent fingerprint, so that an enterprise discharging the specific pollutant is positioned, but the fluorescent fingerprint monitoring cost is high, and the fluorescent fingerprint monitoring method is difficult to be applied to real-time monitoring of water pollution and illegal sewage outlets in a large scale.

Detailed Description

The present invention is further described below in conjunction with the following figures and specific examples so that those skilled in the art may better understand the present invention and practice it, but the examples are not intended to limit the present invention.

The embodiment of the automatic early warning and sample reserving method for excessive pollution discharge comprises the following steps:

carrying out big data monitoring on the water quality parameters of the sewage discharge gates and obtaining the sewage discharge characteristics of each sewage discharge gate; through big data monitoring, can obtain the scope of every kind of water quality parameter of every time under the enterprise conventional condition, because every enterprise blowdown time is different, the content and the kind of pollutant in the waste water of discharging are all inequality, consequently every time of every enterprise every scope of every kind of water quality parameter is also inequality, and the combination of a plurality of water quality parameters forms the unique blowdown characteristic of every enterprise.

Constructing the pollution discharge characteristic of a pollution discharge doorway as a pollution discharge doorway early warning basic library; the pollution discharge characteristic obtained through big data monitoring is the conventional pollution discharge condition of an enterprise, the conventional pollution discharge condition is constructed as the pollution discharge early warning basis of the enterprise, and the actual condition is met.

And comparing the water quality parameters monitored in real time by the sewage discharge gate with the water quality parameters in the early warning basic library of the sewage discharge gate, and performing early warning and sample reservation judgment on the excessive discharge and the illegal discharge ranges according to the comparison result. When each sewage outlet can perform sewage discharge monitoring, if the water quality parameters of the enterprise monitored in real time exceed the range in the early warning database of the sewage discharge gate of the enterprise, the standard exceeding sewage discharge of the sewage discharge gate is indicated, so that the standard exceeding sewage discharge of the enterprise corresponding to the sewage discharge gate is determined in real time, and real-time feedback is realized. And respectively detecting the pollution discharge and the sample reservation of the enterprise, determining whether the pollutants in the pollution discharge of the enterprise and the pollutants in the sample reservation are the same or not, and further determining the specific pollutants in the super-emission of the super-emission enterprise. If individual water quality parameters monitored by a sewage discharge gate in real time are only instantaneously different from water quality parameters in the early warning basic library, and other water quality parameters are not abnormal, early warning and sample reservation are not performed, but the water quality parameters in the early warning basic library are corrected, because only the instantaneous water quality parameters are abnormal, excessive sewage discharge or sewage theft discharge of an enterprise cannot be explained, a monitoring probe is likely to be instantaneously contacted with a certain foreign matter, so that the monitoring data is inaccurate, and early warning is performed at the moment to easily form false alarm, so a parameter revision function is set in the embodiment. When the enterprise steals, the water quality parameters monitored by the downstream enterprise sewage discharge gate exceed the standard, the water quality parameters are compared with the water quality parameters in the sewage discharge gate early warning basic library at the moment, the quantity relation between the type and various types of the water quality parameters exceeding the standard is not matched with the water quality parameters in the sewage discharge gate early warning basic library, the upstream tracing can be carried out, the proportion relation between the type and various types of the water quality parameters exceeding the standard is compared with the water quality parameters of other sewage discharge gate early warning basic libraries, the actual steal enterprise is finally determined, and the real-time tracing of the sewage discharge enterprise is realized.

Furthermore, besides the big data monitoring of the water quality parameters of the sewage discharge gate, the big data monitoring of the water quality parameters of the pump station is carried out at the same time, and the sewage discharge characteristics of the pump station are obtained; the pump station has gathered the waste water of each blowdown gate discharge, carries out big data monitoring through the quality of water parameter to the pump station, can obtain the range of total blowdown at every time every kind of quality of water parameter, forms the blowdown characteristic of pump station.

Constructing the pollution discharge characteristic of a pump station as a pump station early warning basic library; namely forming the early warning basis of the total pollution discharge.

And comparing the water quality parameters monitored by the pump station in real time with the water quality parameters in the pump station early warning basic warehouse and the sewage discharge doorway early warning basic warehouse, and performing early warning and sample reservation judgment on the super-drainage and steal-drainage ranges according to the comparison result. Because the condition of total pollution discharge is monitored by the pump station, when the water quality parameters monitored in real time for the pump station exceed the range in the early warning basic warehouse of the pump station, the condition that the pollution discharge of upstream enterprises exceeds the standard can be judged. If the pollution discharge door of the upstream enterprise also monitors that the pollution discharge exceeds the standard, mutual verification can be carried out, and double monitoring on the pollution discharge exceeding the standard is realized. And if the water quality parameters monitored by the upstream sewage discharge doorways are normal and the water quality parameters monitored by the pump station exceed the standard, the phenomenon of stealing drainage without water quality monitoring in upstream enterprises can be judged. The method comprises the steps of comparing the types of the overproof water quality parameters and the proportional relation among the water quality parameters monitored by a pump station with the water quality parameters in a sewage discharge gate early warning basic library to obtain specific enterprises for super-drainage and steal-drainage, and if the types of the overproof water quality parameters and the proportional relation among the water quality parameters cannot be matched with the water quality parameters in the sewage discharge gate early warning basic library, the enterprises for steal-drainage are not provided with water quality monitoring, and the enterprises for super-drainage and steal-drainage and the specific pollutants for super-drainage and steal-drainage are specifically determined through the detection of the sewage discharge and sample reservation of the enterprises. The difficulty of positioning the over-standard sewage disposal enterprises is greatly reduced, and the quick and accurate positioning is realized. Similarly, when individual water quality parameters monitored by the pump station in real time are different from the water quality parameters in the early warning basic library instantaneously, the water quality parameters in the early warning basic library are corrected. Because only individual parameters exceed the standard instantly and other parameters do not exceed the standard, the enterprise pollution discharge exceeding the standard cannot be judged, and false alarm can be prevented by correcting the parameters.

In this embodiment, the water quality parameters for big data monitoring of the sewage gate and the pump station include TDS, PH, salinity, conductivity, chromaticity and SS suspended solids. The water quality parameters can determine the pollution discharge characteristics of enterprises, and the enterprises can uniquely determine the pollution discharge according to the relation among the water quality parameters.

In order to realize the monitoring and early warning method, the invention discloses an automatic early warning and sample reserving device for over-standard sewage, which comprises a controller 10, a water quality monitor 20 and a TDS (total dissolved solids) monitor 30, wherein the water quality monitor 20 and the TDS monitor 30 are respectively arranged at each sewage discharge gate and a pump station, and each water quality monitor 20 and TDS monitor 30 are respectively connected with the controller 10. Through setting up water quality monitoring instrument 20 and TDS monitor 30 at each blowdown gate and pump station, can realize that the real-time supervision early warning to the blowdown gate reaches traceing back to the blowdown of upper reaches enterprise, and the quick location is surpassed and is arranged, steal the blowdown enterprise. Wherein, the water quality parameters monitored by the water quality monitor 20 comprise PH, salinity, conductivity, chroma and SS suspended solids. The controller 10 is a PLC controller 10.
