生物过滤氧化反应器处理焦化废水

针对钢铁厂焦化车间采用普通活性污泥工艺处理焦化废水 ,出水水质经常超标 ,且对冲击负荷适应力差的情况 ,使用生物过滤氧化反应器 (BIOFOR)工艺对废水进一步进行处理 ,运行结果表明 ,BIOFOR表现出良好的抗冲击负荷能力 ,对CODCr、NH3 N、SS、油类、酚、氰化物等主要污染物的去除率都分别为 6 4 7%、79 8%、76 6 %、5 2 1%、95 4 %、6 1 4 % ,出水水质高于GB8978 1996第二类污染物二级排放标准。

BIOLOGICAL FILTRATION OXIDATION REACTOR FOR TREATING COKE PLANT WASTEWATER

Due to the fact that the activated sludge process is used to treat coking wastewater in a coking plant,whose effluent can not meet the discharge standard.Therefore a biofiltration oxidation reactor is used to further treat the wastewater.The results show that the efficiency of this process is stable and feasible and the system displays a higher resistance to shock.The average removal rates of COD Cr ,NH 3-N,SS, oils, volatile phenol and cyanide are 64.7%, 79.8%, 76.6%, 52.1%, 95.4%,61.4% respecitvely.The quality of effluent meets discharging standard of our country.(GB8978-1996 the second level of national discharged standard for the second contaminants)
