A^2/O工艺生化处理农药废水研究

Pesticide wastewater biological treatment by A^2/O process

考察了A2/O工艺某农药污水生化处理系统的实际处理效果,对该厂生化系统进行了1年的跟踪监测,结果表明,在进水浓度有较大波动时,进水CODCr、氨氮、TP浓度分别在950~2 500、18~43、50~71.7 mg/L时,经改良A2/O工艺处理后,出水CODCr,氨氮、TP的平均浓度分别为188、4.7、8 mg/L,对CODCr、氨氮、TP的平均去除率分别达到84.99%、87.64%、75.97%。

The actual processing effects of A^2/O process in a pesticide wastewater biochemical treatment system in Nantong are investigated in this study. Sequential monitoring is applied to the treatment system for one year. The results indicate that when a large concentration fluctuation is presented in the influent,namely,CODCr,NH3-N and TP in the influent are 950- 2 500 mg /L and 18- 43 mg /L 50- 71. 7 mg /L,respectively,the concentrations of CODCr,NH3-N and TP in the effluent treated with modified A^2/O process can reach 188,4. 7 and 8 mg /L,respectively. Their removal rates are 84. 99%,87. 64% and 75. 97%,respectively.
