摘要
主要探讨了气提式循环反应器处理污水的几个有关问题 :载体选择 ,提升区的截面大小选择 ,载体生物膜和游离活性污泥的特点。试验结果表明 :载体材料中 ,焦炭稍优于炉渣 ,塑料效果最差 ;提升区应该存在最优截面尺寸 ,使载体的提升循环量最高 ;载体生物膜的存在 ,增加了生物量 ,提高了处理效率 。
This paper discussed some problems of wastewater treatment by an airlift loop reactor.These included the selection of a carrier,size of lift area and characteristics of a carrier biofilm and suspended activated sludge.The test results showed that coke and cinder particles were better than those of plastics;selection of optimum diameter of lift area could increase the carriers lift and circulation;and a carrier biofilm could increase MLSS,improve the efficiency of the treatment;and it played an important role in nitrification.
