摘要
为减少炼油厂含酚污水的污染,从生活污泥中培育出噬酚菌,以生物陶粒作为填料,用新型固定生物床对含酚污水进行工业试验。结果表明:在含酚污水COD小于500 mg／L,酚浓度小于130 mg／L的条件下,含酚污水仅需经过2-3 h的处理,就可使酚的降解率大于85％,COD的降解率大于60％,出水酚浓度小于20 mg／L,COD小于200 mg／L。
In order to decrease the pollution of phenol-containing wastewater in refinery, the commercial test is carried out on a new biological bed by using bacteriophage phenol bred from domestic sludge and taking biological ceramsites as the packing. The result shows that under the condition of COD in phenol-containing wastewater less than 500 mg/L and phenol concentration less than 130 mg/L, the degradation rate of phenol and COD is higher than 85% and 60% respectively only after the phenol-containing wastewater was treated for 2-3 hours. The concentration of phenol in the treated wastewater is less than 20 mg/L and that of COD is less than 200mg/L.
