| 摘 要： | 选取某高校生活污水为研究对象,采用绿藻复氧-升流式外回流微氧污泥床反应器,对经过厌氧预处理后的低碳氮比生活污水进行处理。结果显示,反应器处理效果良好,对COD、NH4+-N、TN和SS的去除率分别为69.23%、90%、82%和91.06%,出水水质达到GB 18918-2002的一级A标准。由于利用绿藻光合作用产氧,故节省了100%曝气能耗;且该系统采用菌藻分离的方式,对反应器内溶解氧含量控制更精确。

| Abstract: | The green algae aeration-upflow external reflux micro-oxygen sludge bed reactor was used to treat domestic sewage of a university.The domestic sewage with low carbon-nitrogen ratio after anaerobic pretreatment was treated.The results showed that,the treatment effect of reactor was good,the removal rates of COD,ammonia nitrogen,total nitrogen and SS in the reactor were 69.23%,90%,82%and 91.06%,respectively.The effluent quality could meet the first level A standard of GB 18918-2002.The reactor saved 100%aeration energy consumption due to the utilization of green algae photosynthesis to produce oxygen.In addition,the way of bacteria and alga e separation was applied in the system to control the dissolved oxygen content in the reactor more accurately. |
