摘要
考察了SBR工艺处理造纸废水的效果，以及pH值、曝气时间、进水浓度对COD去除率的影响。试验结果表明，pH值为6．5～7．5，曝气时间为6h，进水浓度为949mg／L时，COD去除率可达到81．8％，出水水质达到国家规定的造纸行业废水排放标准。
SBR process is studied to treat papermaking wastewater. The effect of pH, aeration time and concentration is investigated. The test results show that pH is 6.5 - 7.5, aeration time is 6 h, concentration is 912 mg/L, the removal rate of COD is 83.1%. Effluent quality meets the state＇ s paper industry effluent discharge standards.
