Slaughter waste water treatment equipment: (1) After the front-end septic tanks, waste water still contains most of the macromolecular organic pollutants, and its further degradation to small molecules, to prepare for the subsequent aerobic biochemical, and taking into account waste water excessive nitrogen and phosphorous must be facilities for aerobic - alternate operating environment of oxygen to achieve nitrification - denitrification alternate operation to achieve the nitrogen and phosphorus removal effect here by setting the pool acid hydrolysis subsequent aerobic treatment of effluent part of the return to the pool acid hydrolysis. 
 (2) of wastewater into the aerobic pool after pool acid hydrolysis, here the aerobic tank is divided into two sections, its benefits is that in a variety of aerobic segment, showed the spatial distribution of microorganisms depending on the environment, have targeted has better removal efficiency. 
 (3) treatment of the wastewater biochemical treatment facilities after a front-end, a large degree of degradation of the organic pollution load. Wastewater chroma is still difficult standard to the removal of chroma, taking into account the reduction of COD and ammonia nitrogen and total phosphorus reduction in coagulation and sedimentation, can be set up and dosing targeted Pharmacy. 
 (4) two recoil sedimentation tank effluent into the pool disinfection, strict disinfection and final discharge standards.
