Planning Study On SS Pollution Control Of Water Environment In Slender West Lake Scenic Area

In recent years, the problem of water environment non point source pollution is becoming more and more prominent in the construction of urban scenic areas in China. Suspended solids (SS) is one of the important pollutants in the non point source pollution, which has a wide range of pollution and strong randomness, which seriously damage the ecological balance of the water environment. The best SS (BMPs) is a system of controlling the non point source pollution theory system, how to use the appropriate BMPs technical measures to effectively control the pollution, is the urgent need to solve the problem of water pollution control planning in the current urban landscape area.This paper takes the Slender West Lake scenic area in Yangzhou as an example, from the basic theory, the domestic and foreign relevant literature, on-site investigation and experimental study of SS pollution, in-depth analysis of BMPs technology measures in control of the Slender West Lake scenic area SS pollution, combined with the design scheme, and explore the SS pollution control planning strategy, in order to the current urban landscape water pollution control planning and construction. The content of this paper mainly includes the following 5 aspects:(1) This paper introduces the general situation of water environment pollution, non point source pollution, SS pollution and water pollution control planning of Slender West Lake scenic area in Yangzhou, and puts forward the research background, research significance, research methods and technical route. This paper introduces the concept, main hazard, source process, testing methods and related standards.(2) Describe the location, topography, climate, social environment and historical and cultural landscape of Slender West Lake scenic area, quantitative analysis of the structure of the Slender West Lake scenic area, construction group, square road and hydrological network structure, at the same time, find out the existing problems in the research area, and provide the relevant indicators for BMPs technology and SS pollution control planning.(3) The water samples with different points of Slender West Lake scenic area were collected and the experimental tests were carried out to get the conclusion that the water environment of the Slender West Lake scenic area was polluted by V, and the SS content in different water areas and different time were analyzed.(4)Based on the analysis of the current situation and the structure of green space, select the appropriate BMPs technology measures, combined with the SS content of the experimental results, formulated the "diversity of control runoff pollution" and "series governance of water diversion point source" two kinds of schemes, for the study area water environment planning to lay a theoretical and experimental foundation.(5) Based on the SS pollution experiment research and BMPs technology measure application scheme design, the system proposed the idea, the principle and the method, and has formulated the "resist external pollution", "the construction of the runoff pollution control network" and "the flood control, the landscape and the ecology coordinated development" "three defense" plan.
