System and method for automatically regulating quality of standard-exceeding water in city sewage pipe network

Abstract

The invention provides a system and method for automatically regulating the quality of standard-exceeding water in a city sewage pipe network. The system comprises a sequentially-connected multistage pump station, which is connected to a sewage treatment factory through a pipe network neutralizing and regulating device. Each pump station comprises a first reservoir for receiving and neutralizing sewage and a second reservoir for storing water that does not exceed the standards. The first reservoir can reduce the pH value in the reservoir by dynamically regulating the water outflow of the reservoir according to the pH value of the reservoir of the pump station. When the pH value of one pump station of multiple pump stations in different grades exceeds the standard, the water outflow of the station is reduced, and the sewage is converged in the pipeline to carry out mixing and neutralizing so as to adjust the pH value.

Description

technical field [0001] The invention relates to sewage treatment technology, more specifically, to an automatic adjustment system and method for urban sewage pipe network exceeding the standard water quality. Background technique [0002] For the adjustment of the water quality exceeding the standard in the urban sewage pipe network, the existing technology is all about the treatment of the fixed flow, and there is no corresponding adjustment mechanism. The traditional method is that the sewage discharged from the city is directly sent to the sewage treatment plant after being collected and transported, and the water quality is extremely unstable. Once a large amount of sewage discharged beyond the standard directly enters the sewage treatment plant, when the excessive sewage exceeds the treatment capacity of the sewage treatment plant, it will cause the sewage treatment plant to stop production and cause serious economic losses and environmental pollution.

AI Technical Summary

Problems solved by technology

Once a large amount of sewage discharged beyond the standard directly enters the sewage treatment plant, when the excessive sewage exceeds the treatment capacity of the sewage treatment plant, it will cause the sewage treatment plant to stop production and cause serious economic losses and environmental pollution.

[0003] In addition, in sewage treatment, the treatment capacity is adjusted according to the monitored data. Due to the instantaneous increase of accidental excess water, the entire treatment system needs to increase the treatment capacity, but in fact this is a short-term behavior that inevitably causes excessive water Energy consumption and waste of resources

[0004] Moreover, the instantaneous sewage exceeding the standard has not been treated in advance, so that the subsequent pipe network will be subject to further pollution pressure, and the source and degree of the pollution source cannot be accurately judged.
