摘要:
通过现场调研和水样分析，估算梅龙湖汇水区入湖污染负荷量，明确主要污染负荷来源，并提出有针对性的水环境质量提升措施。分析结果表明：梅龙湖水体为IV类水，其中TN和TP严重超标，为中度富营养化；从上游污水处理厂出水口至湖体，污染物浓度沿程逐渐降低，总体表现为污水处理厂出水浓度＞新林村附近河道水样浓度＞国道北侧湿地出水水质＞梅龙湖湖体水质；农田面源污染物和污水处理厂出水是梅龙湖水体污染的主要来源，其中污水处理厂出水中TN、TP、CODcr和NH3-N负荷量均占总负荷量的72%以上；通过布置“雨水蓄积装置”、厨余垃圾堆肥器、分散式人工湿地和一体化污水处理装置等，可以大幅提升梅龙湖水环境、生态环境质量，并有效削减梅龙湖汇水区入湖污染负荷量。
Abstract:
Through on-site investigation and water sample analysis, the pollution load of Meilong Lake catchment area was estimated, the main pollution load sources were identified, and targeted measures for improving water environment quality were put forward.The results showed that the water body of Meilong Lake was Class IV water, in which TN and TP were seriously exceeded the standard, which was moderate eutrophication.From the outlet of the upstream sewage treatment plant to the lake body, the pollutant concentration gradually decreased along the course, which was generally shown as the concentration of effluent from the sewage treatment plant > the concentration of river samples near Xinlin Village > the concentration of wetland effluent from the northern side of the National Road > the concentration of water body of Meilong Lake.The non-point source pollutants in the farmland and the effluent from the sewage treatment plant were the main sources of water pollution in the Meilong Lake.The TN, TP, CODcr and NH3-N loads in the effluent of the sewage treatment plant accounted for more than 72% of the total load.Through the arrangement of "rainwater storage device", kitchen waste compostor, dispersed constructed wetland and integrated sewage water treatment devices could greatly improve the water environment and ecological environment quality of Meilong Lake, and effectively reduce the pollution load into the lake in the catchment area of Meilong Lake.
