Abstract

The invention discloses a sewage treating and recycling system and method for high-concentration polyester slices. Sewage of different properties is shunted, and a treatment system and method in which a flotation device, homogeneous acidification, a QCS (Quality Control System) efficient anaerobic reactor, an efficient aerobic biodegradation pool, clarifying and an automatic mud extraction and distribution device are combined are adopted. The method comprises the following steps of: treating high-concentration organic waste water produced by polyester slices; treating three-waste waste water with different pretreatment processes, treating in a combined way, and comprehensively reducing pollutants with an efficient aerobic biodegradation pool treatment process; and performing advanced treatment by clarifying, filtering and separating, so that discharge of water within controlling indexes of a national standard or recycling is ensured. The method has the advantages of simple and convenient process flow, low engineering cost, low running cost, high automatic degree, and simple, quick and convenient running and management.

Description

technical field [0001] The invention relates to the technical field of a high-concentration polyester chip sewage treatment and recycling system method, in particular to a method for diverting pretreatment of waste water with different properties, combined with homogeneous acidification, QCS high-efficiency anaerobic reactor and high-efficiency aerobic biodegradation pool , clarification, automatic sludge lifting distribution device and filtering method to fully degrade the pollutants in the wastewater, and finally treat the effluent to meet the discharge standard or meet the recycling index. Background technique [0002] The rapid development of the polyester industry has also brought some problems, especially environmental pollution (which mainly focuses on wastewater). The wastewater produced by the esterification of the polyester workshop is a kind of high-concentration organic chemical wastewater. The wastewater contains relatively high concentrations of ethylene glycol...
