Abstract

A novel modified sequencing batch reactor was proposed to treat municipal wastewater. The modified SBR had a special structure consisting of 4 tanks with different anaerobic/anoxic/aerobic function. A pilot-scale modified SBR process was researched to treat urban wastewater. The effluent TN was 10 mg/L. The TN removal efficiency was 58%. The NH4+-N removal efficiency was 98%. The average effluent NH4+-N was lower than 0.8 mg/L. The result showed the novel modified SBR was advantageous for nitrification bacteria growth. The TP removal efficiency was 81%. The average effluent TP concentration was less than 0.75 mg/L. The effluent TP concentration below 0.75 mg/L was got on 95% of the operational days. The result showed the novel modified SBR was advantageous for PAO bacteria growth.

改性SBR去除营养物质的中试研究

提出了一种新型的序批式反应器处理城市污水。改造后的SBR具有特殊的结构，由4个不同厌氧/缺氧/好氧功能的池组成。研究了一种改良SBR工艺处理城市污水的中试工艺。出水TN为10 mg/L。TN去除率为58%。NH4+-N去除率达98%。出水平均NH4+-N低于0.8 mg/L。结果表明，新型改性SBR有利于硝化细菌的生长。TP去除率达81%。出水TP平均浓度小于0.75 mg/L。95%的运行天数出水总磷浓度低于0.75 mg/L。结果表明，新型改性SBR有利于PAO细菌的生长。
