- 摘要:
- 为落实 “水十条”等国家政策要求，提升污水处理效能，改善水环境质量，我国重点流域区域已陆续制定高于《城镇污水处理厂污染物排放标准》（GB 18918—2002）一级A标准的主要污染物地方排放限值。经大规模系统调研分析，共性难点为如何有效摸清本底，识别现状问题，形成技术可行、经济合理的技术对策。系统构建了“四位一体”精准诊断技术方法，涵盖“问题初筛—难点解析—系统诊断—应用验证”四个紧密衔接、前后依托的诊断步骤，系统提出各步骤的重点目标及实施方案，以常州江边污水处理厂三期为例进行了系统应用说明。该技术方法已收录于江苏、广东等地发布的提标政策指导文件，为我国城镇污水处理系统提标建设及精细化运行管理提供了系统技术支撑。
- Abstract:
- In order to implement the national policy requirements such as Water Pollution Control Action Plan, enhance the sewage treatment efficiency and improve the water environment quality, the local discharge limits of major pollutants in key basins and region of China have been formulated one after another, which are all higher than that of the first class A standard of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). Through large-scale systematic investigation and analysis, the common difficulties of upgrading include how to find out the background effectively, identify the current situation, and put forward the technically feasible and economically reasonable countermeasures. In this paper, the “four in one” accurate diagnosis technology method is systematically constructed, covering the four closely connected and back-to-back operation steps of “problem preliminary screening-difficulty analysis-system diagnosis-application verification”, the key objectives and implementation plan of each step are put forward systematically, and the system application of the systematic and accurate diagnosis technology in Changzhou Jiangbian WWTP is introduced. The technical method has been included in the upgrading policy guidance documents issued by Jiangsu, Guangdong and other provinces, which provides systematic technical support for the upgrading construction and refined operation management of urban wastewater treatment system in China.
