摘要
养猪场废水是农业重大污染源。本文介绍了养猪场废水的水质特征,对养猪场废水的各种处理工艺进行了较全面的比较分析。目前主要采用厌氧技术治理养猪场废水,但是单一的厌氧技术是难以达到预期的处理效果,组合工艺才是使处理水质达到排放或回用标准的最好方法。自然生态处理方法具有能耗省,投资成本低,处理效果好,资源回收利用率高等特点,是一个值得推崇的养猪场废水理想的后续处理技术。
Piggery wastewater is a significant agricultural pollutant resources. In this paper,the characteristics of piggery wastewater were introduced and the present wastewater treatment processes were compared and analyzed. At present,piggery wastewater is treated through anaerobic processes, but it's not enough to get expected results and meet the discharge standard. Actually integrated processes are the best ways to meet the discharge or reuse criterions. Natural ecological treatment process is characteristic of low energy cost,low capital expenditure,good effect,and efficient resource reuse,so it is a successive method for piggery wastewater treatment.
