BIOFOR工艺处理中成药废水

采用一段式生物过滤氧化反应器(BIOFOR)处理中成药生产废水与部分生活污水的综合废水。运行1a的结果表明:当进水CODCr为500mg/L,BOD5为230mg/L,SS为250mg/L,BOD5容积负荷为4·1kg/(m3·d),气水比为6·6∶1时,除冬季排水CODCr偶尔高于60mg/L外,其它季节排水中CODCr≤50mg/L,系统出水达到《污水综合排放标准》(GB8978-1996)一级排放标准。

TREATMENT OF CHINESE TRADITIONAL PHARMACY WASTEWATER BY BIOFILTRATION OXYGENATED REACTOR(BIOFOR)

One stage biological filtration oxygenated reactor(BIOFOR) was used to treat Chinese traditional pharmacy wastewater which was mixed with some domestic wastewater.One-year-operating data revealed that when the concentrations of COD_ Cr ,BOD_5,SS of the influent were respectively 500 mg/L,230 mg/L,250 mg/L,the volume loading of BOD_5 was 4.1 kg/(m~3·d),and the gas-water ratio was 6.6∶1.Only in winter,the effluent COD_ Cr was occasionally above 60 mg/L,others were generally less than 50 mg/L.The water quality of final effluent meets the first-order of Integrated Wastewater Discharge Standard(GB8978-1996).
