养猪场产污特点及环境影响评价要点分析

Pollution characteristics and environmental impact assessment of pig farms

我国畜牧业的发展速度令人瞩目,牛、羊、猪等畜牧动物的养殖已形成规模化,但却带来了较大的污染问题。由于我国畜牧业环境治理工作起步较晚,也没有根据其生产特性的产污系数及排污系数进行,导致畜牧业环境治理效果并不令人满意。本文分析了养猪场的污染原因及特点,并阐述了养猪场环境影响评价的排污系数检测方法,指出了减少养猪场排污的具体改进策略。

The development speed of animal husbandry in China is remarkable.The breeding of cattle,sheep,pigs and other animal husbandry has been basically large-scale,but it has brought about a large pollution problem.Due to the late start of animal husbandry environmental governance in China,the environmental governance of animal husbandry has not been carried out according to the pollution production coeffi cient and sewage discharge coeffi cient of animal husbandry production characteristics,which leads to the unsatisfactory effect of animal husbandry environmental governance.This paper mainly analyzes the pollution characteristics and causes of pig farms in pig breeding,expounds the detection method of pollution discharge coeffi cient in environmental impact assessment of pig farms,and points out the specifi c improvement strategies to reduce the pollution discharge of pig farms.
