摘要
首先,对荆州市护城河水体进行了取样分析与水质评价,结果表明:溶解氧浓度、高锰酸盐指数接近国家Ⅳ类水标准限值,NH3-N和5日生化需氧量指标超过Ⅴ类水标准限值,总体污染严重。最后,提出了以生物修复为主的水污染治理措施。
At first, the assessment on the water quality of Jingzhou City Moat, which is in Hubei Province of the central China, was made by analyzing the monitoring data. The result shows that the concentrations of both dissolved oxygen and permanganate have approached the limited value of the fourth-class water according to nation's standard; both ammonia-nitrogen and 5-day biochemical oxygen demand are over the limited value of the fifth-class water. The conclusion is that the moat has been seriously polluted. At last, some suggestions were proposed that bioremediation could be a successful strategy for controlling water pollution.
