According to the quality of this kind of wastewater,simple aerobic or anaerobic treatment cannot meet the requirements of treatment. In the specific project design, we adopted the process of “regulating tank + air float + hydrolytic acidification tank +A/A/O reaction tank”. Practice has proved that the process is not only economical and reasonable, stable operation, but also high treatment efficiency.The effluent can reach the following indexes: CODcr≤120mg/l, BOD5≤60mg/l, SS≤120mg/l, NH3-N≤25mg/l, TP≤3.0mg/l.

In addition to using farm waste gas treatment equipment, some methods can also be used to reduce the generation of odor. For example, the excrement of livestock and poultry should be cleaned up in time. It needs to be cleaned up about three times a day. If it is not cleaned up in time once, it may increase Odor pollution. The choice of feed should also consider whether it can be fully digested and absorbed, which can effectively prevent the phenomenon of feces and uric acid. The last is to control the quantity and timely ventilation, which can reduce pollution and further reduce the difficulty of farm waste gas treatment.
