A brief talk on the malpractice of rain pollution confluence

Rain and sewage confluence refers to the rainwater and domestic sewage mixed with the same kind of drainage canal collection and transportation, according to the construction specifications, rainwater and domestic sewage should be discharged separately, but due to the early non-standard or various reasons, rain and sewage confluence still exists in some urban drainage system, today, Denor Xiaobian for you to sort out a rain and sewage confluence of the drawbacks.

Firstly, from the perspective of cost, if the combined system is adopted, it is better to control and prevent water pollution, but it will make the size of the main pipe is too large, the sewage capacity will increase a lot, the construction and operation costs will also increase significantly, and the pump station and sewage plant of the combined system is higher than the cost of the shunt system. From the point of view of maintenance management, so the flow rate in the confluence pipe is low in sunny days, easy to produce precipitation, and only when the rain storm water can be washed away the precipitation.

Therefore, according to the reform of urban sewage planning in recent years, the treatment mode of rainwater sewage combined system is gradually withdrawing from the historical stage, and the split system is more widely used in the treatment of urban sewage. Sewage treatment is based on sewage treatment equipment, with the development of our economy, sewage treatment equipment is also constantly changing.

Denor has been engaged in the research and development and production of rainwater and sewage lifting equipment for many years. Recently, the company's latest integrated intelligent interceptor well is improved on the basis of the integrated precast pump station, which further realizes the diversion treatment of rainwater and sewage while realizing the lifting of rainwater and sewage. The equipment can realize the dry season pollution interception, but also can realize the initial rain interception discharge, rainy season direct discharge, before rain and other functions, with good market development prospects, welcome customers to come to consult, investment to join, win-win cooperation!
