微生物降解1,2,4-三氯苯试验研究

The Experiment Research of Degradation of 1,2,4-Trichlorobenzene by Microorganism

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1,2,4-三氯苯等污染物.小试结果表明:经低浓度水源水中1,2,4-三氯苯驯化后,当停留时间为6d,1,2,4-三氯苯的去除率在70%以上,TOC的去除率在55%～85%之间,CODMn的去除率在40%～60%之间.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1,2,4-三氯苯等有机污染具有较明显的改善效果.

1,2,4-trichlorobenzene added in Meiliang Bay was degraded through the use of enriched microbes in Taihu Lake by artificial media. The result shows that after the domestication of low organic pollutants concentration, the biodegradation efficiency of 1,2,4-trichlorobenzene was above 70% , when the settle time was 6 days. The biodegradation of TOC and CODM, was respectively between 55% -85% and 40% -60%. It is evident that the trace quantity organic pollutants of 1,2,4-trichlorobenzene in the source water quality from Meiliang Bay in Taihu Lake could be well degraded by enriched microbes on the artificial media.
