Abstract

The invention discloses an improved biochemical pool based on a BIOLAK pool body. The improved biochemical pool comprises a BIOLAK pool body, which is internally provided with an anaerobic pool, an aerobic pool, a sedimentation pool and a stabilization zone which are communicated from front to back in sequence, wherein the aerobic pool is a biological pool, the geomembrane at the bottom of the biological pool is removed, the improved biochemical pool further comprises a concrete inner shell, a longitudinal partition wall, a second water inlet, a submersible stirrer, a first transverse partition wall, a second transverse partition wall, a third transverse partition wall, a mixed liquid reflux well, a through-wall pump, an inner reflux pipeline, a plurality of vertical stirrers, a pluralityof aerators, a sludge reflux channel, an adjustable aeration device, a stirrer and a mud suction machine. According to the invention, the traditional BIOLAK pool body is transformed into an A2O pool body, the flow state of sewage in the original BIOLAK pool body is changed into plug flow from complete mixing, the effluent quality stably reaches the national standard first-grade A standard, and theproblem that effluent TN of a traditional BIOLAK process cannot stably reach the standard is solved.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an improved biochemical pool based on a Baileke pool body. Background technique [0002] The Biolak process, also known as the hanging chain aeration process, is a sewage treatment process introduced from Germany. Its main feature is that the aeration tank adopts an earthen tank anti-seepage structure, HDPE anti-seepage film is laid on the bottom of the tank, and the aeration device adopts an unfixed floating mobile chain aeration system. The biochemical pool of Baileke process includes anaerobic pool and aerobic pool. Depending on the hanging chain in the swing state in the aerobic pool, multiple anoxic and aerobic alternate states can be formed to realize the denitrification function. The effluent treated by the Baileke process can stably meet the first-level B standard of the "Pollutant Discharge Standards for Urban Sewage Treatment Plants" (GB18918-2002). [0003] With the i...
