Item 1 Upgrading project of a sewage treatment plant in an industrial park
The industrial park is dominated by calcium carbonate stone enterprises, and the production wastewater contains a large number of powder particles and high salinity. The designed treatment scale of the project is 20,000 tons/day. Previously, the sewage treatment process of "AO+diatomite+UV" was adopted. Failed to meet the discharge standards, the "hydraulic clarification tank + AO + ceramic membrane MBR" process is now used, and the effluent meets the national "Urban Wastewater Treatment Plant Pollutant Discharge Standard" (GB18918-2002) stipulated in the Class A standard.

Item 2 Sewage treatment plant in a township area
Mainly collect and treat domestic sewage in towns. The project adopts the core technology "AO process + ceramic membrane MBR" sewage treatment technology, with a designed treatment scale of 1,000 tons per day, and the effluent water quality index meets the "Urban Sewage Treatment Plant Pollutant Discharge Standard" (GB18918-2002) Class A standard.

Item 3 Sewage treatment plant in an industrial park
It mainly collects and treats industrial wastewater and domestic sewage in the stainless steel product industrial park. The project adopts the core technology "AO process + ceramic membrane MBR" sewage treatment technology, with a designed treatment scale of 5,000 tons per day, and the effluent water quality index meets the "Urban Wastewater Treatment Plant Pollutant Discharge Standard" (GB18918-2002) Class A standard.

Item 4 High-salt wastewater treatment plant in a chemical park
The sewage treatment plant mainly treats the production wastewater discharged by the chemical companies that produce epoxy resin, polyester resin, and TGIC water-based ink in the park. The wastewater has the characteristics of high COD and high salinity. The designed processing scale of the project is 5000 tons/day, adopting the process of "regulation + hydrolysis acidification + biochemistry + ceramic flat membrane MBR + flocculation sedimentation", and the effluent reaches the national "Urban Sewage Treatment Plant Pollutant Discharge Standard" (GB18918-2002) stipulated in Class A standard.

Item 5 Coal mine water treatment in a certain area
The project is designed to process 2000 tons/day and adopts the process route of "flocculation sedimentation + inclined plate sedimentation + ceramic membrane filtration". This process has a significant effect in removing particulate matter, and the turbidity reaches the standard to meet the effluent standard and realize the recycling of high-quality treated water. After long-term stable operation of membrane filtration equipment, the flux is stable at 150LMH-200LMH.
