| 摘 要： | 以安徽六安市淠河水作为试验原水,研究了采用轻质滤料滤池对主要污染物浊度、化学需氧量(COD Mn)、氨氮(NH4+-N)等的处理效果、反冲洗对COD Mn和NH4+-N的影响效果等.结果表明,轻质滤料生物滤池对浊度、COD Mn、NH4+-N的平均去除率分别为37.5%、20%和64%.反冲洗对于轻质生物滤料滤池去除COD Mn、NH4+-N都有一定的影响,COD Mn的影响大于NH4+-N,当反冲洗1 h后,COD Mn去除率不到10%,而对于NH4+-N,反冲洗2 h后,去除率能达到60%,7 h后基本达到冲洗前水平.

| Abstract: | With the sample from Pihe River, this paper attempts to conduct a study of the effects of biostyrene filter and backwash on the main pollutants in terms of the turbidity, CODM. and NH4 ＋ - N. The resuits show that the average removal rate of turbidity,CODM, and NH4^＋ -N reaches 37.5% ,20% and 64% respectively. Back washing has a certain influence on both CODexn and NH4 ^＋ - N, though the latter is less affected than the former. Less than 10% of CODM. is removed an hour after the backwash,but the rate for NH4^＋ - N can reach 60% two hour after backwash, and a basic recovery will need 7 hours. |
