| 摘 要： | 针对某工业园区污水厂出水TN超标问题,对工业园区和污水厂存在的问题进行了分析,提出源头冲击管控、推流器角度改造、进水余氯控制、跌水富氧控制、回流硝化液DO控制、外加碳源优选的6大优化措施。采取以上措施进行改造后,污水厂出水TN稳定达标,出水水质达到GB 18918—2002《城镇污水处理厂污染物排放标准》中的一级A标准。

| Abstract: | Aiming at the problem of excessive TN in effluent water of a wastewater treatment plant in industrial park, the existing problems in industrial park and wastewater treatment plant were analyzed respectively,and six optimization measures were proposed includes: source impact control, thruster angle modification, control of influent residual chlorine, control of waterfall oxygenation, DO control of reflux nitrifying fluid, and applied carbon source. After adopting the above measures, the TN in effluent water stably met the discharge standard, the effluent water quality met the requirement of level A grade 1 in GB 18918—2002 Discharge standard of pollutants for municipal wastewater treatment plant. |
