摘要

利用复合变速生物滤池深度处理氧化沟污水厂的二级出水，开展了生产性试验研究。考察了三种水力负荷下滤池的处理效果。结果显示，CODcr平均去除率最高为21.42%，去除率随水力负荷升高而下降；NH3N平均去除率最高达43.19%；浊度平均去除率最高达60.40%。试验表明：对可生化性差、营养物质贫乏的污水厂二级出水进行深度处理，复合变速生物滤池是一种较理想的工艺。

Abstract

Utilizing a combined velocityvariable biofilter，a fullscale experiment was carried out on advanced treatment of secondary effluent from an oxidation ditch wastewater plant．The study was made on the performance of the biofilter at three different hydraulic loadings．The results showed that the highest average removal rate of CODcr reached 21.42%

which increased with hydraulic loadings rise; the highest of those of NH3N and turbidity was 43.19% and 60.40%.respectively.The study shows that this biofilter technology is an good process for advanced treatment of secondary effluent which is characterized by deficiency of nutrition and low biodegradability．
