紫茎泽兰炭对好氧颗粒污泥处理废水的影响

采用MUASB作为反应器,利用城市污水处理厂的活性污泥为接种污泥,加入不同级数紫茎泽兰炭通过间断曝气方式培养好氧颗粒污泥并用于处理高浓度有机废水。结果发现在20~40目、40~60目、60~80目、80~100目、100~190目紫茎泽兰炭中,添加40~60目紫茎泽兰炭在好氧颗粒污泥处理污水的表现上较为明显。在连续一个月的污水处理中,在好氧颗粒污泥中添加紫茎泽兰炭可调节污泥性能,并提高COD、NH3-N、TP的去除率。在COD8 000 mg/L时去除率达到90%以上,NH3-N去除率最高为99%以上,TP最高去除率达85%以上。

The effect of carbonized Eupatorium adenophorum on the wastewater treatment by Aerobic Granular Sludge

By seeding activated sludge in sewage treatment plants, Different sizes carbonized Eupatorium adenophorum was added in MUASB reactor for the cultivation of aerobic granular sludge, which was used for treatment of high concentration organic wastewater. The results showed that in 20-40 mesh, 40-60 mesh,60-80 mesh,80-100,100-190 mesh carbonized Eupatorium adenophorum, the addition of 40-60 mesh can enhanced the treatment efficiency obviously. In the wastewater treatment for one month, the addition of carbonized Eupatorium adenophorum can not only adjusted the character of AGS, but also can raised the removal efficiency of COD, NH3-N, TP. The COD removal rate can reached above 90% when COD>8000mg/L, the NH3-N removal rate can reached above 99%; and TP can reached above 85%.
