用移动床生物膜反应器处理石化废水

Treatment of Petrochemical Wastewater in Moving Bed Biofilm Reactor

采用悬浮填料移动床生物膜反应器处理石化废水 ,在水力停留时间大于 6 h、反应器填料投加率为 5 0 %的条件下 ,出水 COD、NH3- N、SS、浊度等均达到国家排放标准 ,在水力停留时间大于 8h时 。

Chemical wastewater has been treated in moving bed biofilm reactor with suspended filler.When the HRT is more than 6 h and the filling proportion of reactor is 50%,effluent COD,NH 3 N,SS and turbidity can meet the national discharge standards.When the HRT is over 8 h,an excellent nitrification effect can be realized.
