摘　　要：根据美国环保署(EPA)和地方环境保护的要求,美国华盛顿特区Blue Plains污水处理厂采用增加后置反硝化、污泥热水解和雨污合流深隧建造等方式实现提标改造。污水处理排放总氮(TN)达到4mg/L以下要求,污泥实现热电联产并提高泥质至Class A,合流制雨污水的收集率进一步提高。Based on the requirement of US EPA and local environment protection, DC Water＇s Blue Plains Wastewater Treatment Plant used adding post-denitrifieation process, sludge thermal hydrolysis process, rain and sewage combined tunnel to achieve upgrading reconstruction. The total nitrogen of effluent from WWTP reached 4 mg/L, the quality of sludge was improved to Class A, which achieved heat and power cogeneration, the collection rate of rain and sewage from combined sewer system had a further increase.
