Analysis And Study On Standard Improvement Reconstruction Project Of Sewage Treatment Plant In Southern Area,Changchun

With the reform and opening-up and the development of city economy,respective development of Changchun have made significant achievements.Changchun southern area sewage treatment plant standard improvement reconstruction project is a feasible project to adapt to the development of Changchun.To preserve Changchun southern water source,southern area sewage treatment plant effluent water standard fulfilling <City&Towns sewage treatment plant pollutants emission standard> grade I B standard to improve to grade I A standard requirements.Based on sewage treatment plant current operational status analysis,find key factors influencing reconstruction,analyze and compare respective reconstruction technique,proposing plan fulfilling southern part sewage treatment plant standard improvement reconstruction.The article conducts analytical research on Changchun southern part sewage treatment plant standard improvement feasible project through domestic and abroad sewage treatment current condition.1.Give a detailed introduction and illustration on southern part sewage treatment plant current status,and propose requirements on sewage treatment plant current status,sewage treatment plant current designing capacity,sewage treatment plant actual water inflow,sewage influent and effluent water quality,etc.;and influent and effluent water quality after standard improvement.2.The discuss of feasibility and necessity of modification project of southern part sewage treatment plant standard improvement.Feasibility: Mainly manifests on according to the regulation of <City&Towns sewage treatment plant pollutants emission standard>,river emission standard is grade I A requirements.Illustrate the standard improvement project feasibility from southern part sewage plant technical procedure,personnel,funds,etc.current condition.Necessity: With the continuity of economic development,social development and people's lives requirement,technical procedure feasibility constantly improve,project implementation feasibility condition constantly improve(Including funds 147 million 684 thousand RMB totally from self-funding and current instruments and personnel).Totally fulfill southern part sewage plant standard improvement modification requirement.3.Primarily analyzed the plan of southern part sewage treatment plant standard improvement reconstruction project,to choose from sewage treatment technique projects,mainly analyze influent and effluent water quality,while analyze the factors influencing reconstruction Factors.Determined standard improvement modification technique is carbon-source dispensing processing technique;determined advanced treatment technique includes: coagulation and sedimentation technique,filtering technique,V type filter pond,efficient fiber filter pond,disc-filter,active sand filter pond,and analyze and compare;determined two feasible plans,micro-flocculation technique + fiber pond technique and mechanical coagulation-lattice flocculentincline plate precipitation + V type pond technique.Through comparison of two plans current condition and economic benefits finally chose plan I(micro-flocculation + fiber filter pond)as the southern part sewage treatment plant standard improvement reconstruction project advanced treatment technique,achieving it's economical and practical,while fulfill the grade I A standard.4.After the implementation of southern part sewage treatment plant standard improvement reconstruction project,its impact on environmental protection,energy-saving and derived social,environmental and economic benefits,will have a significant effect on Changchun southern part economic culture and people's lives,improving people's living standard.The project fulfills national policies and regulations,is a necessary measurement protecting Songhua river basin water environment quality.Improve area water environment requirements.Therefore,the construction of project is necessary and urgent.Suggest improve sewage emission charge system,earnestly implement sewage facilities compensation use policy,promote effluent system and treatment system benign cyclic development.Fulfill Changchun overall plan development requirement.
