Technical Field

The invention belongs to the technical field of wastewater treatment devices, and particularly relates to a high-efficiency reaction tank for industrial wastewater treatment.

Background

At present, the method for treating high-concentration organic sewage mainly comprises a physical and chemical process and a biological treatment process. The physical and chemical process for treating sewage has the problems of high treatment cost, difficult guarantee of effect, unstable operation and the like. Therefore, biological treatment methods attract the attention of researchers, and the anaerobic process is widely concerned with the advantages of low energy consumption, high load, small amount of excess sludge and the like. An upflow anaerobic sludge blanket reactor (UASB) is a typical representative of a new generation of high-efficiency anaerobic reactors, and has been applied to industries generating high-concentration wastewater in printing and dyeing, papermaking, chemical industry and the like in recent years, and shows good treatment effect. In addition, the sewage is treated by the UASB anaerobic reactor, so that not only can a good treatment effect be achieved, but also the renewable clean energy hydrogen or methane can be produced.

The UASB reactor that currently commonly uses is the hollow cylindrical steel jar body, and the jar body is by arranging sludge blanket, suspension room, three-phase separator and collecting chamber from last in proper order down, and there are collection chamber and outlet duct on the upper portion of collecting chamber, and the bottom of the jar body sets up inlet tube and mud pipe. The sewage is conveyed into the tank body through the water inlet pump and then contacts anaerobic bacteria in the sludge bed to generate methane; partial marsh gas enters a suspension chamber with sludge particles, a three-phase separator separates solid, liquid and gas, the separated gas and liquid are respectively collected by a gas collection chamber and a water collection chamber, and the sludge particles fall back to a sludge bed.

Although UASB reactors of this type are widely used, problems arise during their use. For example, in a region with loose geology and easy collapse in a coastal region, the problems of deformation, damage and the like of pipeline equipment caused by the fact that a tank reactor is easy to settle are solved; also, the problem of severe corrosion of the tank due to seawater erosion occurs. In addition, along with the rapid development of the quality of high-strength steel, the wall thickness of the storage tank is gradually reduced, but the wind resistance stability of the reactor tank body is increasingly poor due to the reduction of the quality, and in addition, the UASB tank body is mostly placed on the ground and has larger longitudinal height, so that the problems of poor wind resistance stability, easy inclination or deviation and the like generally exist in coastal and northwest wind-sand dense areas, and even the tank body is deformed and toppled by serious people.

In addition, in order to save cost, the conventional UASB reactor is generally made of anticorrosive carbon steel, so that the service life of the reactor is greatly shortened. In order to avoid the above problems, ensure the normal operation of the UASB reactor and reduce the potential safety hazard of the UASB reactor, it is necessary to improve the design of the current UASB reaction apparatus.

[ example 1 ]
