Abstract

The invention discloses a mud-blocking biological anaerobic reactor for treating livestock and poultry breeding sewage. The biological anaerobic reactor comprises an anaerobic reactor, an aerobic pool and a sedimentation tank, wherein the top of the anaerobic reactor and the top of the aerobic pool are communicated, and the top of the aerobic pool and the top of the sedimentation tank are communicated; a water inlet is formed in the bottom of the anaerobic reactor, a stirrer is arranged at the bottom of the anaerobic reactor, and a three-phase separator is arranged at the top of the anaerobic reactor; multiple layers of baffling mud blocking plates are arranged in the anaerobic reactor above the stirrer, and a pipe mouth of a water inlet pipe in the aerobic pool is arranged at the bottom of the aerobic pool; multiple layers of aeration devices are arranged inside the aerobic pool, and outlets of air holes of the aeration devices are downward or are inclined downward; the bottom of the sedimentation tank is funnel-shaped, and a water outlet is formed in the top of the sedimentation tank so as to output a supernatant. According to the biological anaerobic reactor, the concentration and activity of mud of a system are improved through improving an anoxic and aerobic internal structure, so as to better utilize a carbon source in a sewage treatment system. The biological anaerobic reactor has the characteristics that high-concentration microorganisms can be maintained and the treatment is stable.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to a mud-resistance type biological anaerobic reactor used for sewage treatment of livestock and poultry breeding, and belongs to the technical field of sewage treatment. Background technique [0002] With the adjustment of my country's agricultural structure and the advancement of agricultural industrialization, the large-scale and intensive livestock and poultry breeding industry has developed rapidly, and the resulting environmental pollution has become increasingly serious. Livestock and poultry breeding pollution has become the third largest pollution source after industrial pollution and domestic pollution, and has become one of the main causes of rural pollution in our country. [0003] At present, most aquaculture sewage, especially pig sewage, is mainly based on biochemical methods, and the most common is the A2 / O treatment process. The biological pool is arranged through aerati...
