煤渣过滤、生物转盘和生态池在处理生活污水中的联合应用

STUDY ON JOINT APPLICATION OF COAL CINDER ,ROTATING BIOLOGICAL CONTACTOR AND ECOLOGICAL POOL TO DISPOSAL OF DOMESTIC SEWAGE.

目的:探索生活污水处理的新方法。方法:采用过滤、生物转盘和生态池串联的方法对生活污水进行处理。结果:出水BOD5的质量浓度可由90 . 46mg L-1 ,CODcr的质量浓度可由97. 46mg L-1 ,NH3-N的质量浓度可由1 2 9 .3 3mg L-1 降至1 0 . 3 9mg L-1 。结论:通过煤渣过滤、多级生物转盘处理、生态池吸收,有机物污染指标NH3 N、CODcr。

Objective:To find the new methods of wastewater treatment.Methods:Coal cinder filtration,rotating biological contactor and ecological pool were jointly applied in wastewater disposal.Results:The concentration of the index which can show the degree of organic pollution as the above reduced significantly after wastewater was treated by the three-stage.Conclusion:Wastewater was preliminarily disposed and the same time the white pollution is also descended.Social benefits and economic effects have been acquired remarkably.
