禽畜养殖场废水处理的研究

Research on Wastewater Treatment of Livestock Farm

随着经济的迅速发展和人民生活水平的提高,集约化、规模化的禽畜养殖业也迅速的崛起和发展起来。禽畜养殖场排放的粪污量也逐年增加。这些污染物如不适当处理,将会造成当地生态环境和农田的严重污染,使自然河水富营养化,地下水的硝酸盐严重超标,少数地区传染病与寄生虫病流行。规模化禽畜养殖业生产过程中产生废水等污染物已达到非治不可的地步。针对集约化、规模化禽畜养殖业的特点,对其废水处理的工艺进行了研究。

With the rapid economic development and the improvement of people＇s living standard, the intensive large-scale livestock farming rises and develops rapidly. The amount of dung emissions of livestock farms has increased year by year. The improper handling of pollutants wiU cause the serious pollution of the local ecological environment and agricultural land, the natural river eutrophication, the overproof nitrate in ground water, and the popular infectious and parasitic diseases in some areas. Wastewater and other pellutants produced from the productive process of livesteck farming must be controlled and cured. According to features of intensification and large-scale in livestock farming, technology of wastewater handling is researched in this paper.
