【摘要】 自行设计和初步建成了扬水曝气器与生物接触氧化联合工艺系统,并应用于北方某城市微污染源水的预处理;通过动态试验,对生物接触氧化预处理效果进行了理论分析和试验研究;实验结果表明,在水温为10~25℃条件下,采用生物接触预氧化处理微污染水源水是可行的,实验条件下水中污染物可达到较好的去除效果:CODMn去除率为10%~25%,氨氮去除率为40%~70%,浊度去除率为10%~25%,藻类去除率为15%~30%,总铁去除率最高可达80%。更多还原

【Abstract】 A technical system with lifting water and aeration combination with biological contact oxidation was designed and manufactured.The system was used to pretreat the micro-polluted source water in North China.Based on the dynamic experiment,a theoretical analysis was made and it was verified that biological contact oxidation technique was feasible to treat the micro-polluted source water.The experimental results showed that removal rates of ammonia-N,CODMn,turbidity,total Fe and algae were 40%～70%,10%～15%,10%～25%,20%～80%and 15%～30%respectively.更多还原
