摘要
在春季低温条件下,利用厌氧生物滤池、好氧生物炭滤池处理生活污水,比较两者的性能,探讨低成本处理生活污水的方法.结果表明,厌氧生物滤池停留时间为14h,COD的去除率可达83%;在滤速为0·4—1·2m·h-1范围内,好氧生物炭滤池的TOC去除率高于厌氧生物滤池,TN去除率低于厌氧生物滤池.
Anaerobic filter and aerated filter belong to a kind of biological membrane method. Domestic wastewater was treated by anaerobic biological filter and aerated biological carbon filter under the condition of the lower temperature in spring. The objective of the research is to investigate a low-cost way of wastewater treatment. The results showed that the COD removal was as high as 83% when HRT was 14 hours. In the range of 0. 4- 1.2 m ·h^-1, the TOC removal in aerated filter was higher than in anaerobic filter, but the TN removal is reverse.
