生物浮動床處理電廠廠區生活污水

Treatment of power plant sewage based on suspended biofilm bed reacter

摘要: 利用"生物浮動床-過濾-臭氧殺菌"技術處理電廠廠區生活污水,耐有機負荷沖擊和水力沖擊的能力強,對COD_cr、氨氮、總磷有較好的去除效果.COD_cr總去除率最高可達到95%,出水COD_cr穩定在10-30 mg/L,;總磷去除率達到50%以上,出水總磷質量濃度低于0.5mg/L;對NH₃-N的去除率基本可以穩定在80%以上;濁度消減率可達到84%,細菌殺滅率大于99.9%,出水細菌濃度小于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.
