- 摘要:
- 厂网一体化是为保证城镇排水系统的安全和高效运行，基于污水水量、水质、水位等要素，对污水处理厂和排水管网进行统筹建设和协调运行，是未来城镇排水系统的发展方向。江西某市政污水综合治理项目设计处理水量为1.5 × 104 m3/d，采用多模式A/A/O + 缺氧池 + MBR工艺。为了应对调试运行初期进水量及进水浓度过低、出水总磷偏高、雨季进水水质突降和水量突增等问题，一是在调试阶段采取了污水管网水质水量摸排与污水厂分步调试相结合的方式，二是采取了厂网联动调整、外加碳源、优化加药设备等三种运行措施，最终使污水厂调试运行合格，总结得到厂网一体化调试运行的成功经验。
- Abstract:
- Plant-network integration is to ensure the safety and efficient operation of an urban drainage system. Based on the factors of sewage volume, water quality and water level, the integrated construction and coordinated operation of wastewater treatment plant and drainage pipe network is the development direction of urban drainage system in the future. The design treatment capacity of a comprehensive municipal wastewater treatment project in Jiangxi is 1.5×104 m3/d, and the process consists of multi?mode A/A/O, anoxic tank and MBR. To solve the problems such as low wastewater quantity and pollutants concentration in the initial stage of operation, high total phosphorus in the effluent, sudden increase of wastewater quantity and decrease of pollutants in the influent in rainy season, two measures were carried out as follows: first, the combination of wastewater quality and quantity investigation in the sewage pipe network and step commissioning of the wastewater treatment plant; second, linkage adjustment of the plant and network, addition of external carbon source and optimization of the dosing equipment. Finally, the commissioning and operation of the wastewater treatment plant was qualified, and successful experience for plant?network integration commissioning and operation was summarized.
