In addition, most urban domestic sewage plants adopt mature biological treatment processes, but the tail water discharged by the urban domestic sewage plants is seriously polluted by nitrogen and phosphorus. At present, sewage treatment at home and abroad mainly uses a mode of constructing various structures to form different treatment process facilities, and most pollutants are removed by an active carbon adsorption method, a membrane separation method, an advanced oxidation method, an ultrasonic radiation degradation method, an electrochemical oxidation method, an ozone oxidation method, a microorganism treatment method and the like, and then tail water is short-circuited to a pipe network for receiving sewage through a discharge pipeline or is directly discharged into a nearby receiving water body. Usually, the tail water discharge pipeline is a precast pipeline made of concrete pouring structures, PVC, concrete or glass fiber reinforced plastics and the like, and can only meet the discharge and diversion functions of wastewater.
In the prior art, there are many patents (or patent applications) related to improving the performance and function of tail water discharge pipelines, such as "CN 201210107988", a method for degrading grease in a restaurant sewage pipeline "," CN201310528568 ", a low pollution tail water advanced treatment device", "CN 201850198U", a high efficiency denitrification wetland system for advanced treatment of tail water in a sewage plant "," CN201210107988 ", a method for degrading grease in a restaurant sewage pipeline", "CN 201410433567.8", a permeable sewage dual-energy winding structure wall pipe "," CN 2015147678.
