Weiyuan shale gas in Neijiang City, Sichuan

Installed high-efficiency sewage treatment equipment for the zero-discharge project of the sewage treatment plant in the Weiyuan Shale Gas Comprehensive Utilization Circular Economy Industrial Park in Neijiang City, Sichuan Province, with an average daily discharge of (25,000T/d). The process flow of this project adopts the process flow: regulating tank + degasification sedimentation + hydrolysis acidification + integrated biochemical tank + high-efficiency sedimentation tank + austenite oxidation + MBBR + fiber turntable + UF + RO + DTRO + MVR (1200T/d evaporation), achieving wastewater discharge/reuse in compliance with standards and setting an industry environmental protection benchmark.

Influent water quality: Industrial park wastewater

Effluent standard: "Water quality of industrial water for urban sewage recycling"
