工程主要内容包括截污工程、清淤工程及景观工程。浦东河全长3872m,平均宽度约9~35m。河道设计常水位4.0m,20年一遇洪水位4.96m~7.56m。根据勘察报告显示:该河道淤泥层层厚2.7-18.2m,呈深灰色,饱和,流塑,干强度中等,韧性较差等特点。
The main contents of the project include sewage interception works, desilting works and landscape works. Pudong river has a total length of 3872m and an average width of about 9 ~ 35m. The designed normal water level of the river is 4.0m, and the flood level with a return period of 20 years is 4.96M ~ 7.56m. According to the survey report, the silt layer of the river is 2.7-18.2m thick, dark gray, saturated, flow plastic, medium dry strength and poor toughness.
综合治理建设内容包括:河道内淤泥固化处理、截污、调蓄池、行洪能力的保持和提升、以及长期水质在线监测系统等。浦东河为黑臭河道,通过综合治理要求水体不黑臭,透明度大于25厘米,溶解氧(DO)>2mg/L,氨氮浓度(NH3-N)<8mg/L,氧化还原电位(ORP)>50mV,河床河面无垃圾,周边居民满意度调查满意度达90%以上。施工后使河道变深、变宽,河水变清,居民居住环境得到改善,达到“水清、河畅、岸绿、景美”的目标。
The construction contents of comprehensive treatment include: solidification treatment of sludge in the river, sewage interception, regulation and storage tank, maintenance and improvement of flood discharge capacity, long-term on-line water quality monitoring system, etc. Pudong river is a black and smelly river. Through comprehensive treatment, it is required that the water body is not black and smelly, the transparency is greater than 25cm, the dissolved oxygen (do) > 2mg / L, the ammonia nitrogen concentration (NH3-N) < 8mg / L, the redox potential (ORP) > 50mV, there is no garbage on the river bed, and the satisfaction of surrounding residents is more than 90%. After the construction, the river will become deeper and wider, the river will become clear, and the living environment of residents will be improved to achieve the goal of "clear water, smooth river, green bank and beautiful scenery".
