Water inlet monitoring and adjusting system in centralized sewage treatment plant in chemical industry park as well as method thereof

Abstract

The invention discloses a water inlet monitoring and adjusting system in a centralized sewage treatment plant in a chemical industry park as well as a method thereof, which belongs to the technical field of waste water treatment. The water inlet monitoring and adjusting system comprises an on-line monitoring device, a PLC control unit, a minisize collection pool and an enterprise waste water conveyer pipe, a waste water regulating reservoir is communicated to the minisize collection pool, an emergency treatment pump and a waste water elevator pump are arranged on the waste water regulating reservoir, the emergency treatment pump is connected to an emergency treatment system, the emergency treatment system is connected to the waste water regulating reservoir through a back flow, the waste water elevator pump is connected to a subsequent biochemistry system; the emergency treatment system comprises an iron-carbon micro-electrolysis treatment unit, a fenton oxidation treatment unit and a neutralization and sedimentation treatment unit which are connected in order through a pipeline. and the monitoring and adjusting method employs a mode of two-stage monitoring, one-stage processing and two-stage adjusting processes to monitor and adjust water. According to the invention, water quality of water from the sewage treatment plant can reach the standard, and the impact of water quality fluctuation to subsequent biochemical treatment system can be reduced at maximum degree.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, and more specifically, to a system and method for monitoring and regulating water inflow of a centralized sewage treatment plant in a chemical industry park. Background technique [0002] Most of the current industrial parks are composed of various types of enterprises, mainly including chemical, pharmaceutical, printing and dyeing and other enterprises that pollute the environment. This type of enterprise wastewater has the characteristics of complex water quality components, high toxicity, high salinity, and difficult treatment. In response to the above situation, domestic chemical parks generally adopt the wastewater treatment mode of "enterprise pretreatment + centralized treatment by park sewage plants", that is, the wastewater generated by enterprises in the park is pretreated, and after reaching the takeover standard of the park's sewage plant, it is transported to sewage trea...

AI Technical Summary

Problems solved by technology

[0005] The present invention provides a chemical industrial park for the problems of complex components of incoming water received by centralized sewage treatment plants in chemical industrial parks, large fluctuations in water volume, and large differences in water quality among different enterprises; and problems such as monitoring blind spots and non-standard monitoring methods in the online monitoring of incoming water quality. Centralized sewage treatment plant water inflow monitoring and adjustment system and method; the technical solution provided by the invention adopts the "one enterprise, one pipe" method to connect the wastewater discharged by different enterprises to the sewage collection pool, so as to ensure that the incoming water can be traced back to the source. Monitoring + primary treatment + two-stage regulation” monitors and regulates incoming water, which can effectively ensure that the quality of incoming water received by the sewage treatment plant meets the standard, and minimize the impact of water quality fluctuations on the subsequent biochemical treatment system
