基于水环境约束下污水厂提标必要性与经济性方案分析——以宿迁市经开区污水处理厂为例

Analysis of Necessity and Economic Feasibility of Standards Upgrading for Sewage Plants based on Water Environment Constraints--Taking Suqian Economic Development Zone Sewage Treatment Plant as example

在水环境考核日趋严格的背景下,污水处理厂提标改造已成为区域水环境质量改善的重要手段之一。污水处理厂提标改造应根据水环境容量测算等方式,定量评判各污染源对水环境的污染贡献,进而判定污水处理厂提标的必要性与标准,不可盲目提标,不可过度改造。结合提标水质标准差距与进水水质特质,经工艺可行性、全生命周期成本分析论证后,综合选择经济高效的污水处理厂提标改造方案。

Under the background of increasingly strict water environment assessment,standards upgrading of sewage treatment plants has become one of the important means to improve the quality of regional water environment.According to the calculation methods of water environmental capacity,the pollution contribution of various pollution sources to the water environment should be quantitatively judged in the standards upgrading renovation of sewage treatment plants,and then the necessity and standards of standards upgrading renovation for sewage treatment plants should be studied.Neither blindly raising standards nor excessively transforming them.Combined with the difference of water quality standard and the characteristics of influent water quality,an economical and efficient upgrading scheme of sewage treatment plant is selected comprehensively based on the analysis and demonstration of technology feasibility and lifecycle cost,.
