摘要:
针对九江市琵琶湖因长期受到污染导致水体黑臭的问题，借助Digital Water城市排水管网模拟系统，提出了一套适用于琵琶湖外源污染物削减控制的方法体系，研究过程包括：①梳理研究区排水系统及排口性质；②计算排口和面源污染物负荷产生量；③依据水质目标、生态本底等分析计算水环境容量；④结合水环境控制目标，对研究区提出污染物削减标准；⑤制定污染物削减控制方案；⑥分析整治方案的目标可达性。结果表明，琵琶湖在实施截污工程、水质净化站工程、生态清淤工程、补水活水及生态修复工程和景观提升工程等削减控制工程后，湖区水质明显改善，全年污染物排放总量达到地表Ⅳ类水要求，对COD、BOD5、NH3-N、TN和TP的削减率分别为79%、85%、96%、95%和91%，达到预期目标。
Abstract:
In view of the problem of black and odorous water in Pipa Lake of Jiujiang due to long-term pollution, a set of method system suitable for the abatement control of exogenous pollutants in Pipa Lake was proposed based on Digital Water urban drainage pipe network simulation system. The research process includes: Ⅰ. Sorting out the drainage system and outlet properties of the study area; Ⅱ. Calculating the production of discharge and non-point source pollutant load; Ⅲ. Analyzing and calculating water environmental capacity according to water quality objectives and ecological background; Ⅳ. Putting forward pollutant reduction standards for the study area in combination with the water environment control objectives; Ⅴ. Developing pollutant abatement control programs; Ⅵ. Analyzing the accessibility of remediation program target. Results show that through implementation of abatement control projects such as sewage interception project, water purification station project, ecological dredging project, replenishing and living water ecological restoration and landscape project, the water quality of Pipa Lake improved significantly, the total amount of pollutant discharge for the whole year could reach the level Ⅳrequirements of surface water. The reduction rates of COD, BOD5, NH3-N, TN and TP were 79%, 85%, 96%, 95%, and 91%, respectively, which achieved the expected goals.
