生物浮动床处理电厂厂区生活污水

Treatment of power plant sewage based on suspended biofilm bed reacter

摘要: 利用"生物浮动床-过滤-臭氧杀菌"技术处理电厂厂区生活污水,耐有机负荷冲击和水力冲击的能力强,对COD_cr、氨氮、总磷有较好的去除效果.COD_cr总去除率最高可达到95%,出水COD_cr稳定在10-30 mg/L,;总磷去除率达到50%以上,出水总磷质量浓度低于0.5mg/L;对NH₃-N的去除率基本可以稳定在80%以上;浊度消减率可达到84%,细菌杀灭率大于99.9%,出水细菌浓度小于1/L.

Abstract: The treatment of power plant sewage based on the Suspended Biofilm Bed Reactor (SBBR)-filtra tion-ozone mixed process was studied. The system can endure various organic load impact and hydraulic load impact. The best removal rate of COD_cr reached 95% and the mass concentration ranged in 10-30 mg/L. The removal rate of phosphorus was over 50% and the mass concentration lower than 0.5 mg/L. The removal rate of NH₃-N was over 80%. The removal rate of turbidity reached 84%, more than 99.9% of bacteria had been killed and the bacteria concentration was 1/L.
