Research On The Optimum Selection Of Sewage Treatment Scheme In Zhuorong Hardwareman

The sewage treatment station of Zhuorong Hardwareman was built in 1995, designed treatment capacity is 600 cubic meter per day, it can effectively eliminate such as CN^-,Ni²⁺,Cu²⁺ pollution factors. On the normally, the sewage treatment station can make the water which has been treated come up to the standards of the nation, but it will periodically exceed the provided standard when the station discharged the strong alkalescency cleaner which has a high content of COD.At present, polluted water must not be emitted when it has exceeded theprovided standard, because environmental protection consciousness of humanityhas increasingly been improved, the environmental protection laws and regulationsare increasingly perfected, the strength of putting environmental protection lawsand regulations into practice become more strictly than ever. In the meantime,controlling the polluted water emission according to the standard is a socialresponsibility that must be performed. From above analysis, these problems willundoubtedly be a bottleneck of hindering the normal development of the enterprise.In accordance with the problem of COD exceeding the provided standard andtheory of System Engineering, the thesis firstly has come up with the plan objective,after analyzing influence factors of reform objective, technology level, social factorand economic factor, then structuring an assessment system. Secondly, the thesishas come up with several feasible reform programs in environmental projecttechnology such as biological contact oxidation process, active carbon stickingprocess, and constructed rapid infiltration system. Finally, the thesis hasdetermined active carbon sticking process being most satisfactory program, and hasexplained its advantages in technology aspect and economy prospect, the study alsogive some cautions when it will be carried out. The reform program will solve theproblem of sewage treatment system and will provide necessary safeguard fornormal development and strategy implementation.The selection for the reform program accords with advanced character, and mature character, it will produce obviously economic benefit, social benefit and environmental benefit.
