表面活性剂对SBR反应器中活性污泥运行系统影响的研究

Research of the Toxic Effects of Surfactant on the Activated Sludge System in SBR Reactor

以SBR反应器作为实验室模拟污水处理系统,通过测定活性污泥的氧摄取速率值（OUR）以及氨氮、TP、COD的去除率来研究表面活性剂对活性污泥系统的毒性效应。研究结果表明：当表面活性剂浓度为5 mg/L时,OUR值为33.2 mg/（g·h）,此浓度表面活性剂对活性污泥基本无影响;当表明活性剂浓度为10~40 mg/L时,OUR值随着浓度的增加而减小,即毒性随之增强。

SBR reactor acts as the wastewater treatment system in the laboratory simulation condition. By measuring the activated sludge oxygen uptake rate（OUR） value, the removal rates of ammonia, TP, and COD, the toxic effects of surfactant on the activated sludge system have been studied. The results show that： When the concentration of surfactant was 5 mg/L, the value of OUR was 33.2 mg/（g·h）,The surfactant with this concentration has no effect on the activated sludge; When the concentration of surfactant was 10~40 mg/L, the value of OUR decreased with the increasing of the concentration, that means the toxicity of sodium hypochlorite has enhanced.
