新型高效AOS生物反应器处理畜牧场废水

Treatment of livestock farm waste water with efficient AOS bioreactor

介绍了新型生物反应器——ＡＯＳ污水处理系统的操作过程及现场运行结果。通过在香港元朗农场的现场运行结果表明，ＡＯＳ系统对高浓度猪场废水（ＢＯＤ５ ＞ ４ ０００ ｍ ｇ／Ｌ，ＴＳＳ＞ ２ ５００ ｍ ｇ／Ｌ）的ＢＯＤ５ 和ＴＳＳ去除率分别可达９８％ 和９７％ ，出水质量达到香港环保署制定的ＢＯＤ５ ＜ ５０ ｍ ｇ／Ｌ和ＴＳＳ＜ ５０ ｍ ｇ／Ｌ的直接排河标准。

Process and on the spot operation results of new bioreactor,AOS sewage treament system,are introduced in brief.Results of on the spot operation at Yuanlang Farm in Hongkong show that elimination rates of BOD 5 and TSS of sewage with high concentration from pig farm can be reached 98% and 97% respectively.Quality of tapped water can meet the drainage standard i.e.BOD 5<50 mg/L,TSS<50 mg/L,stipulated by Hongkong Environmental Protection Office.
