摘要
利用人工介质富集太湖水中微生物,降解梅梁湾水源地水质中外加的硝基苯污染物.小试结果表明:经过驯化的生物膜可以有效去除一定浓度范围的微量有机物.当停留时间为7 d时,硝摹苯的去除率在66.2%～75.6%的范围内,在温度为25℃左右、pH为6～9之间,微量有机物的去除效果最佳.可见,通过人工介质富集微生物的方法,对太湖梅梁湾水源地水质中硝基苯等有机污染具有较明显的改善效果.
Artificial media were used to enrich microbe and improve the water resource quality,therefore trace quantity organic pollutants were biodegraded.The result of the test showed that,after domestication,the micro association enriched in the assembled medium could remove corresponding trace quantity organic pollutants in some concentration.At the same time,the congener trace quantity organic pollutants could be biodegraded.When the settle time was 7 days,the removal of trace quantity organic pollutants was between 66.2%～75.6%.When the temperature was 25 degree centigrade,the pH was between 6 and 9,the effect was the best about the removal on trace-quantity-organic pollutants water.It is evident that the trace quantity organic pollutants of Nitrobenzene in the source water quality from Meiliang Bay in Taihu Lake can be well degraded by enriched microbes on the artificial media.
