Abstract

The invention provides a treatment system for mixed wastewater of a development zone. The treatment system comprises a wastewater regulation tank, an anaerobic reaction tank, a multi-grade biochemical tank, an aerobic contact oxidization tank and a sand filter tank, wherein the anaerobic reaction tank is provided with a sand collection region, a sludge region, a mixing region and a separation region in sequence from bottom to top; the separation region comprises a water collection region and a dreg collection region located in the water collection region; the multi-grade biochemical tank comprises an anoxic section and an aerobic section which are separated by a glass plate and a baffle; the aerobic contact oxidization tank is provided with a water inlet pipe, a water distribution pyramid, a membrane assembly and an aeration regulation and control system; the water quantity and water quality of the wastewater are adjusted through the regulation tank and the wastewater enters the anaerobic reaction tank to provides an organic carbon source for a diluting process of phosphorus accumulating organisms; then the wastewater enters the multi-grade biochemical tank and the aerobic contact oxidization tank to be subjected to anoxic and aerobic reaction, and then is precipitated and filtered to reach emission standards.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a mixed wastewater treatment system in a development zone. Background technique [0002] The mixed wastewater in the development zone is mainly from the chemical industry, and the wastewater is mainly industrial wastewater discharged from the production process of dyes, pharmaceuticals, pesticide intermediates and other fine chemical products. The water quality is extremely complex, with deep color and high acidity. The content of organic and toxic substances is high . [0003] It is difficult to meet the requirements of high efficiency, energy saving, low cost and environmental protection by using traditional physical, chemical and biochemical treatment processes to treat mixed wastewater in the development zone. Therefore, based on traditional physical, chemical and biochemical treatment processes, an improved or innovative new combination The research and develop...
