Series sewage intercepting collection pipe method for treating urban black and odorous water body

Abstract

The invention discloses a series sewage intercepting collection pipe method for treating an urban black and odorous water body. According to the method, bearing mechanisms corresponding to confluent main pipes are arranged on a river channel revetment, or positions corresponding to the confluent main pipes in a river channel are piled, the bearing mechanisms or piles are used for supporting and jacking the confluent main pipes, a water outlet of each confluent main pipe is communicated with an intercepting branch pipe, an intercepting well is arranged at a water outlet of each intercepting branch pipe, all the intercepting wells are communicated with each other through pipelines to form intercepting main pipes, a water outlet of each intercepting main pipe is communicated with a municipal sewage pipe network, sewage and rainwater intercepted by the intercepting wells are conveyed to the municipal sewage pipe network through the intercepting main pipes, sewage of the municipal sewage pipe network is communicated to a water inlet of a sewage treatment plant for treating the received sewage, and treated effluent is drained into the river channel. The source of the black and odorous water body is treated, and the method is simple, efficient and low in investment cost.

Description

technical field [0001] The invention relates to the field of water pollution treatment engineering, in particular to a method for treating urban black and odorous water bodies in series for intercepting and receiving pipes. Background technique [0002] With the rapid development of economy and society and the continuous expansion of cities, in the process of urban construction, the pollution of my country's urban water environment is becoming more and more serious. The water bodies in urban rivers are mostly polluted by organic pollutants, nitrogen, phosphorus and other pollutants. It is a common phenomenon in the rivers of cities in our country, and the governance of urban black and smelly rivers will be an environmental problem to be solved in the future. In terms of urban drainage and treatment of black and odorous water bodies, China has always focused on the research of sewage treatment technology, and paid little attention to the urban drainage system. When dealing wi...

Problems solved by technology

[0003] Most of the black and odorous water bodies are located in the old urban areas. Theoretically speaking, the diversion system is more scientific and advanced, and has many advantages. Or it is more difficult to transform the combined system into a completely divided system, and the success rate is low

If the diversion system is adopted, there will be many practical problems such as incomplete separation of upstream rainwater and sewage, large investment, and difficult construction. Therefore, when choosing a drainage system, one should not rely too much on the diversion system to solve the problem. Considering realistic factors, generally in many cities, in For quite a long period of time, the drainage system of most old urban areas will still be in the state of coexistence of confluence system and diversion system

However, in the current urban drainage system, the interception-type combined drainage system has the disadvantages of laying sewage interception pipes on both sides of the river. volume problem
