【摘要】：随着改革开放和城市经济的发展,长春市的各项发展取得了显著的成效。长春市南部污水处理厂提标改造工程是为了适应长春的发展而实施的一项可行性工程。为保护长春市南部水源,南部污水处理厂出水标准由满足《城镇污水处理厂污染物排放标准》(GB18918-2002)的一级B标准提升为一级A标准的要求。根据污水处理厂的运行现状分析,找出影响改造的关键因素,分析对比各种改造工艺,提出符合南部污水处理厂提标改造的方案。本文通过国内外污水处理的现状,对长春南部污水处理厂提标改造工程的可行性方案进行分析研究。1.对南部污水处理厂现状进行了详细的介绍和说明,并对污水处理厂现状,污水处理厂的现设计规模,污水处理厂实际的进水量,污水的进出水水质等;以及提标后的进出水水质提出要求。2.对南部污水处理厂提标的改造工程的可行性和必要进行仔细的论述。(1)可行性:主要表现在依据法规《城镇污水处理厂污染物排放标准》,河流排放标准为一级A的要求。从南部污水处理厂的技术工艺,人员,资金等现有条件,说明此提标工程的可行性。(2)必要性:经济发展的可持续性,社会发展和人民生活的需求,技术工艺的可行性不断提高,工程实施可能性的条件不断完善(包括资金14768.42万元全部来自自筹和现有的设备人员)。完全符合南部污水处理厂提标改造工程的要求。3.重点分析了南部污水处理厂提标改造工程的方案,从污水处理工艺方案选择,着重分析进出水水质,同时对影响工程改造的因素进行分析。确定提标改造工艺为碳源投放加工工艺;确定深度处理工艺包括:混凝沉淀工艺、过滤工艺、V型滤池、高效纤维滤池、转盘过滤器、活性砂滤池,加以分析比较;确定两个可行性的方案,即微絮凝工艺+纤维池工艺和机械混凝—网格絮凝—斜板沉淀+V型池工艺。通过对两方案现有条件和经济效益比较最终选择方案一(微絮凝+纤维滤池)作为南部污水处理厂提标改造工程深度处理工艺,做到经济实用,同时符合一级A标准。4.南部污水处理厂提标改造工程实施后,对环境保护、节能,以及所产生的社会效益,环境效益,经济效益,必将对长春市南部区域经济文化和人民生活起到一个重要作用,同时提升人们生活水平。本工程符合国家政策法规,保护松花江流域水环境质量的必要措施。改善区域内水环境的需要。故项目的建设是必要的迫切的。只有认真完善污水排放的相关有偿收费制度,相关部门切实执行污水设施的可持续发展的使用方针。达成水资源的良性循环的发展要求。
[Abstract]:With the reform and opening up and the development of urban economy. The development of Changchun has achieved remarkable results. The upgrading project of the wastewater treatment plant in the south of Changchun is a feasible project to adapt to the development of Changchun, and to protect the water source in the south of Changchun. The effluent standard of the southern sewage treatment plant is to meet the pollutant discharge standard of the municipal sewage treatment plant (GB18918-2002). According to the operation status of the sewage treatment plant, the requirement of upgrading the first B standard to the first class A standard is introduced. To find out the key factors affecting the transformation, to analyze and compare the various transformation processes, and to put forward the proposal of upgrading the standard in accordance with the southern sewage treatment plant. The present situation of sewage treatment at home and abroad has been adopted in this paper. The feasibility scheme of the upgrading project of the south Changchun sewage treatment plant is analyzed and studied. 1. The present situation of the southern sewage treatment plant is introduced and explained in detail, and the present situation of the wastewater treatment plant is also described. The current design scale of the sewage treatment plant, the actual water intake of the sewage treatment plant, the water quality of the effluent in and out, etc. And the quality of incoming and outgoing water after raising the standard. 2. The feasibility and necessity of the upgrading project of the southern sewage treatment plant are discussed in detail. Feasibility: mainly in accordance with the laws and regulations of municipal wastewater treatment plant pollutant discharge standards. The river discharge standard is the requirement of first class A. from the existing conditions of technical process, personnel and capital of the southern sewage treatment plant, the necessity of the feasibility of the proposed project is illustrated: the sustainability of economic development. Social development and the needs of the people's life, the feasibility of technology and technology are constantly improving. The conditions for the possibility of implementation of the project have been continuously improved (including one hundred and forty-seven million six hundred and eighty-four thousand and two hundred yuan in funds all from self-financing and existing equipment personnel). It fully meets the requirements of the upgrading project of the southern sewage treatment plant. The project of upgrading the standard for the southern sewage treatment plant is analyzed emphatically. According to the selection of wastewater treatment process, the quality of incoming and outgoing water is analyzed, and the factors that affect the engineering transformation are analyzed. The advanced treatment process includes coagulation sedimentation process, filtration process, V type filter, high efficiency fiber filter, rotary plate filter, active sand filter, and analyzed and compared. Identify two feasible options. That is, micro-flocculation process fiber pool process and mechanical coagulation-grid flocculation-inclined plate sedimentation V-type tank process. Through comparing the existing conditions and economic benefits of the two schemes, the final selection scheme (micro-flocculation fiber filter). As the advanced treatment process of the upgrading project of the southern sewage treatment plant. To achieve economic and practical, at the same time in line with the first class A standard .4. after the implementation of the southern sewage treatment plant standard upgrading project, environmental protection, energy conservation, and the resulting social, environmental benefits, economic benefits. It will play an important role in the regional economy, culture and people's life in the south of Changchun, and at the same time improve the living standard of the people. This project is in line with the national policies and regulations. The necessary measures to protect the water environment quality of Songhua River basin and the need to improve the water environment in the area. Therefore, the construction of the project is necessary and urgent. Relevant departments implement the principle of sustainable development of sewage facilities and meet the requirements of virtuous cycle development of water resources.
