摘要
近年来,我国规模化养猪场大量兴起,但猪场废水处理的相对滞后,使得猪场废水成为农业污染的重要源头之一。文章介绍了规模化猪场废水处理3种模式(还田模式、自然处理模式及工业化处理模式)的适用范围、基本内容和研究、应用进展。新的混合工艺更能发挥各种模式的优势,使传统工艺不断优化;而种养结合的生态农业道路,实现养猪业的生态闭合循环,也是规模化猪场废水处理和综合利用的发展趋势。
The number of scaled hoggery has greatly increased in recent years,while the disposal methods of swine wastewater is relatively backward,which makes swine wastewater an important source of agricultural pollution. In this review, three modes of swine wastewater treatments for scaled hoggery are summarized, including land spreading, natural treatment and industrialized treatment. The applicability, basic content, research progress and application progress of each mode are expounded. New combined processes can take the advantages of several modes and therefore optimize the traditional processes. To achieve successive disposal and utilization of swine wastewater, it＇s a potential trend to choose the structure model of combining farming and animal husbandry in agricultural ecosystem so as to balance the ecologic circle.
