The Feasibility Study Of Water Pollution Ecological Control In Handan

According to the basic present condition of the water pollution of Handan, this thesis carries out the analysis and summary for the technique of water pollution father. Analyzed the constructed wetland technical and main craft of the city dirty water processing factory and constructed, and these two kinds of techniques are in dirty water of city manage of application. Among them carried on the main analysis to the principle that the constructed manages the water pollution wetly, and try the constructed in the Handan setting up wetly, and detailed introduced the constructed wetly of design and experiment the design, pass the constructed wetly to the analysis that the pollutant do away with the result in water, explain in the establishment constructed in Handan wetly of possibility. Combine recover from the ecosystem of angle come further circumstance of solve the water pollution of Handan. This to a water shortage of resources and a water shortage of fluid matters keep both of the Handan to speak to have the certain reference value, we still put forward at the same time the city dirty water processing factory and constructed wetly the technique knot put together of suggestion, pass this kind of to combine to carry on to the water pollution organically to manage comprehensively.The results of experiment study show that, under the same water power load, the sewage treatment effect of the constructed wetland whose plant growth condition good obviously is better than that plant growth condition difference the constructed wetland, the Growth of massive weeds, specially the shallow root early fresh weeds, can reduce the constructed wetland purification efficiency. The reed and bulrush show the good growth condition in the constructed wetland experiment, and have the obvious superiority of sewage treatment in the flow pattern constructed wetland, which is the good constructed wetland plant variety. And the yield of the reed and bulrush is great in the constructed wetland biological, which is a kind of very high production biology resources. The SS remove ability of Sheet current type constructed wetland is lower than that of dive flows the type constructed wetland. The windmill grass and loosestrife show good getting rid of dirty ability in the constructed wetland experiment, moreover is the watching plant, may beautify the environment, and possess the value of developing and utilization. With reducing of water temperature, the COD and TN removing rate of the constructed wetland system assumes obviously drop tendency, so the dives flows the constructed wetland is more effective in removing water pollutant, but the water temperature has a more tremendous influence to the COD and the TN purification efficiency of constructed wetland system. According to economic rationality and technical feasibility, it is a very fine treatment way to adopt the constructed wetland to deal with the sewage.
