Therefore, the biochemical method is commonly used in slaughtering wastewater treatment methods. Because of high levels of slaughter wastewater BOD and COD, so in order to get a better treatment effect and reduce the cost of processing, slaughtering waste water processing is often a process of combining a variety of methods. Analysis, the design of anaerobic-aerobic process, it can effectively remove BOD and COD in wastewater, anaerobic biochemical treatment effect is no energy, and reduce the follow-up treatment facilities to handle the load. The design process: raw sewage → → fine grid flotation tank → adjust pool → UASB reactor → biological contact oxidation pond → vertical flow secondary settling tank → standard water, sludge followed by Sinotrans was concentrated after dehydration. The treated effluent of the assessment indicators can be achieved in two standard of Integrated Wastewater Discharge Standard, GB8978-2006 requirements; water can back part the pigsty rinse water and green water, saving water costs.
