兼氧-SBR工艺处理有机磷农药废水试验研究

采用自制的兼氧-SBR反应器对模拟的有机磷农药废水进行试验研究。对活性污泥进行培养、驯化,两个月后,COD去除率达到80%～90%。通过实验确定了一个周期的厌氧时间为2h、好氧时间为6h;研究了进水磷源、有机磷农药浓度对兼氧-SBR反应器处理效果的影响,不添加磷源比添加磷源处理效果要好,进水有机磷的最佳浓度为250mg/L。

Experimental research into treatment of wastewater containing organic phosphorus pesticide by using anaerobic -SBR technology

Experimental research into the simulate treatment of wastewater containing organic phosphorus pesticide by using self-made anaerobic-SBR reactor was conducted,activated sludge was cultivated and do- mesticated,after two months,COD removal rate reached 80-90 percent.The experimental results showed that the periodic anaerobic time was 2 hours and that aerobic time was 6 hours.The influence of phosphate compounds and the concentration of organic phosphorus pesticide on the treatment effect of anaerobic-SBR reactor was studied.The results showed that the treatment effect without adding the source of phosphate was better than the effect with adding the source of phosphate and that the optimal concentration of organic phosphorus was 250 mg/ L.
