Technical Field

The invention relates to the technical field of municipal drainage, in particular to a sewage treatment system.

Background

The sewage treatment is a component of municipal drainage, which is treatment such as purification of sewage by a sewage treatment plant after collecting rainwater or domestic sewage.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to: provided is a sewage treatment system having an advantage of reducing the workload of water purification by separately collecting shallow rainfall and deep rainfall.

Above-mentioned technical scheme realizes through following technical scheme, a sewage treatment system, including rainwater collection device and rainwater purifier, rainwater purifier includes dark rainfall treatment pond and shallow rainfall treatment pond, rainwater collection device includes rainwater sump pit and rainwater collection pipeline, and rainwater collection pipeline is provided with the auto-change over device who is used for switching dark rainfall and shallow rainfall.

Through the technical scheme, the deep rainfall and the shallow rainfall are switched through the switching device, the rainwater is introduced into the deep rainfall treatment pool when the deep rainfall occurs, and when the shallow rainfall occurs, the rainwater is introduced into the shallow rainfall treatment pool, the cost of the deep rainfall treatment pool is lower than that of the shallow rainfall treatment pool, so that the rainwater is reasonably purified, and the workload and the cost in the sewage treatment process are reduced.

Further, the rainwater collecting pipeline comprises a deep rainfall pipeline and a shallow rainfall pipeline, the switching device comprises a rainfall amount detection device for detecting rainfall amount of rainwater and sending out a rainfall amount signal, an electric connection device, a distinguishing device for distinguishing deep rainfall from shallow rainfall and sending out a distinguishing signal after receiving the rainfall amount detection signal, an electric connection device, a selection device for selecting the deep rainfall pipeline and the shallow rainfall pipeline and sending out a selection signal after receiving the distinguishing signal, and a control valve for executing a selection action after receiving the selection signal on the selection device.

According to the technical scheme, the rainfall is detected through the detection device, the distinguishing device is used for distinguishing, the corresponding pipelines are selected through the selection device, the control valve is used for controlling the on-off of the corresponding pipelines, the deep rainfall and the shallow rainfall can flow into the corresponding deep rainfall treatment pool and the corresponding shallow rainfall treatment pool through the corresponding deep rainfall pipelines and the corresponding shallow rainfall pipelines, automatic control is achieved, and manual switching work operation is reduced.

Further, detection device is the level sensor who sets up on the inner wall of sump pit, level sensor's output electric connection is on distinguishing the device.

Through above-mentioned technical scheme, detect the liquid level in the sump pit through level sensor, when the rainfall is less, shallow rainfall pipeline is introduced with water to the sump pit to handle the pond through shallow rainfall and carry out purification treatment, when the rainfall is great, the inflow of rainwater is greater than the drainage rate of rainwater, so the rainwater liquid level in the sump pit will increase, so can enough learn how much of the rainfall of rainwater through level sensor's detection.

Furthermore, the shallow rainfall treatment pool comprises a filtering pool and a sedimentation pool communicated with the output end of the filtering pool, and the output end of the sedimentation pool is communicated with the deep rainfall treatment pool.

Furthermore, the sewage treatment system also comprises an irrigation water outlet pipeline connected to the deep rainfall treatment tank and a deep purification tank communicated with the deep rainfall treatment tank.

Through above-mentioned technical scheme, because need more cost in the deep purification pond, irrigate and need not too pure water, use can be irrigated through simple filterable rainwater, through will irrigating the outlet pipe setting and can reduce the treatment cost of irrigation water on the heavy rainfall treatment pond, simultaneously, the aquatic before the filtration probably contains elements such as more nitrogen, phosphorus, potassium, can regard as the fertilizer in the soil.

Furthermore, the distinguishing device comprises a comparator, the equidirectional input end of the comparator is electrically connected to the liquid level sensor, the reverse input end of the comparator is electrically connected to a reference unit which is used for providing a liquid level reference value and sending a reference signal, and the output end of the comparator is electrically connected to the selecting device.

Through above-mentioned technical scheme, provide a benchmark value through the benchmark unit, compare benchmark value and level sensor's liquid level signal through the comparator, when level sensor's signal is greater than the benchmark value, comparator output selecting signal lets control valve control heavy rain rainfall pipeline switch on, and then lets during the rainwater flows into heavy rain processing pond, can change the liquid level height that triggers through changing the benchmark value, can obtain more accurate liquid level height's trigger value simultaneously.

Further, the control valve comprises a deep rainfall valve for controlling the deep rainfall pipeline and a shallow rainfall valve for controlling the shallow rainfall pipeline, and the deep rainfall valve and the shallow rainfall valve are switched on or off after receiving the selection signal.

Through the technical scheme, the on-off of the deep rainfall pipeline and the shallow rainfall pipeline can be better controlled through the control of the deep rainfall valve and the shallow rainfall valve.

In conclusion, the invention has the following technical effects:

1. the switching device is used for switching deep rainfall and shallow rainfall, rainwater is introduced into the deep rainfall treatment pool when the deep rainfall occurs, and the rainwater is introduced into the shallow rainfall treatment pool when the shallow rainfall occurs, so that the cost of the deep rainfall treatment pool is lower than that of the shallow rainfall treatment pool, the rainwater is reasonably purified, and the workload and the cost in the sewage treatment process are reduced;

2. the rainfall amount is detected through the detection device, the rainfall amount is distinguished through the distinguishing device, the corresponding pipeline is selected through the selection device, the on-off of the corresponding pipeline is controlled through the control valve, so that deep rainfall and shallow rainfall can flow into the corresponding deep rainfall treatment pool and shallow rainfall treatment pool through the corresponding deep rainfall pipeline and shallow rainfall pipeline, automatic control is achieved, and the manual switching operation is reduced;

3. detect the liquid level in the sump pit through level sensor, when the rainfall is less, shallow rainfall pipeline is introduced with water to the sump pit to handle the pond through shallow rainfall and carry out purification treatment, when the rainfall is great, the inflow of rainwater is greater than the drainage rate of rainwater, so the rainwater liquid level in the sump pit will increase, so can enough learn how much of the rainfall of rainwater through level sensor's detection.
