摘要
为了解阿图什氧化塘的污水处理效果,分别于2007年3月和6月对该氧化塘的进、出水水质进行了监测。结果表明:阿图什氧化塘对挥发酚、生化需氧量、氨氮、化学需氧量、悬浮物的去除率较高,达50%以上,而对磷和部分重金属的去除率小于30%,比较低;氧化塘的污水处理效果夏季好于春季;氧化塘出水水质没有完全达到《农田灌溉水质标准》(GB 5084-92)中的旱作标准,与设计要求有一定差距,而且与国家相关排放标准相比,也存在较大差距,但处理后的污水适合外排用于灌溉荒漠植被和经济林,而且可产生良好的生态效益和经济效益。
This paper based on oxidation pond in Atushi as an example, intake and export water quality were monitored from 2007. 3- 2007.6. The results showed that removal rate of COD,NH3 - N, SS, ArOH exceed 50%, but removal rate of P, heavy metal was under 30%. Purificatory effect of oxidation pond was better in surrmaer than in spring. Export water quality failed to reach dryland standard of Standards for Irrigation Water Puality （ GB 5084 - 92）. Oxidation pond sewage was fit for irrigating hungriness vegetation and economic forest, which obtained good economic and ecologic benefits.
