摘要
设计并构建了一个小型人工芦苇床，分析生长了１８个月的芦苇床系统处理污水的效能。结果表明，芦苇床系统处理生活污水的效果，在１ｄ内的ＢＯＤ５去除率达８５％以上、ＣＯＤ达８０％以上、ＳＳ和总大肠菌群的去除率达９０％以上，该系统对ＮＨ３－Ｎ和Ｏ－ＰＯ４－Ｐ的去除效果较差，尤其是对Ｏ－ＰＯ４－Ｐ的去除率很低。去污的最佳滞留时间ＢＯＤ５和ＣＯＤ为２ｄ、ＳＳ为１．５ｄ、总大肠菌群为５ｄ、ＮＨ３－Ｎ为６ｄ、Ｏ－ＰＯ４－Ｐ为１０ｄ。
This paper describes the design and construction of an artificial pilotscale reed bed system and reports the performance of domestic sewage treatment by the bed which has undergone two growth seasons.The results showed that the purifying effect of sewage treatment by RBS was significant.The removal efficiencies of BOD、COD、SS and total coliforms by RSB within one day were 85%、80%、90% and 90% respectively,but those of ammonia and phosphorus were poor.
