接触氧化纤维束过滤工艺处理学校洗涤废水

Application of Contact Oxidation and Fibrous Filter Process for Treatment of Washing Waste Water in University

大学学生公寓的洗浴废水和盥洗废水经接触氧化和纤维束过滤后出水能达到中水回用的标准。接触氧化池BOD5负荷为 0 .2kgBOD/m3 ·d ,气水比为 1∶8,纤维束滤池滤速为 30m/h ,反冲洗周期 12h。实践证明 ,接触氧化纤维束过滤工艺占地面积小、运行费用低 ,适合用于学校中水回用工程。

In this paper the bathing and washing wastewater f ro m student apartment of university were treated to achieve the standard for water reuse by contact oxidaton and fibrous filter.The BOD 5 load of contact oxidati on tank was 0.2kg BOD 5/m 3·d,and the ratio of air to water was 1∶8,the filt ering velocity of fibrous filter is 30m/h,the back washing period is 12h,It was proved that the union process of contact oxidation and fibrous filter is propiti ous to the water reuse of university with small occupied area and low operating cost.
