畜禽养殖废水生物处理技术现状

The Situation of Biological Treatment Technology of Livestock Wastewater

养殖业污水属于富含大量病原体的高浓度有机废水.畜禽粪尿中的氨、磷及水溶性有机物等淋容量很大,如不妥善处理,直接排放进入水体或存放地点不合适,受雨水冲洗进入水体,对地表水或地下水水质均会造成严重污染.文中分析了国内外畜禽养殖废水的好氧生物处理技术、厌氧生物处理技术及混合生物处理技术的现状.

Aquaculture sewage belongs to the high concentration organic wastewater, which is rich in a large number of pathogens. Livestock and poultry manure, ammonia, phosphorus and dissolved organic matter, such as great leac- hing capacity, if not properly treated, discharged into water bodies or the location is inappropriate, washed into the water by the rain, surface water or groundwater quality will cause serious pollution. This article describes the domes- tic and international livestock wastewater aerobic biological treatment, anaerobic biological treatment technology, and the status of hybrid biological treatment technology.
