Chizhou High Tech Zone Overflow Pollution Control Project

Project Overview: Micro charge loaded medium precipitation technology, equipment effluent meets Class A of the Pollutant Discharge Standards for Urban Wastewater Treatment Plants (GB18918-2002)

Quantity of treated water: 40000 T/D

Address: Within the sewage treatment plant of Qianjiang Industrial Park in Chizhou


Project Overview:

To cope with the sudden increase in rainy season water volume, increase the capacity of the sewage treatment plant in the rainy season, and ensure that sewage does not overflow under the premise of intercepting and treating the initial rainwater, the project will set up emergency treatment facilities at the inlet of the Xi'an High-Tech Zone West District Sewage Treatment Plant, and construct a new integrated emergency treatment facility with a capacity of 40,000m3/d, add sodium hypochlorite disinfection devices, renovate the coarse grille and intake pump room of Phase I, and renovate the coarse grille and intake pump room of Phase II. The project aims to solve the problem of excessive rainy season flow into the sewage treatment plant, which leads to overflow and pollution, and better handle the sudden increase in rainy season water volume before the network quality and efficiency improvement takes effect, to ensure that no sewage overflows into water bodies during the rainy season.

Our company is responsible for constructing the new integrated emergency treatment facility and adding sodium hypochlorite disinfection devices. The integrated emergency sewage treatment facility is based on the micro-charged loaded medium (silica sand) sedimentation technology, which utilizes the conventional flocculation sedimentation method by adding PAC flocculant and the highly recoverable micro-charged loaded medium in the coagulation stage to improve the settling speed of flocs, and supplemented with sludge return devices to improve the coagulation reaction effect. The integrated emergency sewage treatment facility is designed to meet the water quality standard of Grade A1.
