摘要
从探讨猪场废水的危害性和污染特征着手,对目前国内外猪场废水研究现状进行了系统分析。总结出3种常用的处理模式,即还田处理模式、自然处理模式和工厂化处理模式;阐述了每种处理模式的基本处理方法、适用范围以及各自的优缺点;针对猪场废水有机污染物浓度高、难达标排放这一特点,提出了目前猪场废水处理技术研究领域中存在的主要问题及今后主要的研究方向。
This paper starts with discussing the harm and characteristics of piggery wastewater, analyses systemically the current domestic and foreign research on piggery wastewater, sums up three kinds of disposal mode： the returning farmland mode, the natural mode and the factory mode, and expatiates the basic treatment methods, the applicable range and the merit and shortcoming of each mode. Considering the high concentration of organic pollutants and its difficult treatment, the writer finds out some problems existing in eurrent research fields on piggery wastewater treatment and puts forward a research direetion in the future.
