摘要：
采用微电解-厌氧水解酸化-序批式活性污泥法 (SBR)串联工艺处理化学合成制药废水 ,试验分别考察了pH、温度、停留时间以及污泥负荷对整个工艺处理效果的影响。结果表明 ,原废水BOD/CODCr约为 0.13 ,属难生物降解废水 ,经微电解-厌氧水解酸化处理后 ,出水BOD/CODCr可达0.63 ,可生化性大大提高。维持SBR进水CODCr在 1500mg/L左右 ,污泥负荷为0 .5kgCODCr/(kgMLSS·d)曝气 8～ 10h ,出水CODCr在 2 0 0mg/L以下 ,达到了GB8978-1996二级排放标准。

Abstract:
An experiment of micro-electrolysis-anaerobic hydrolysis acidification and sequencing batch reactor(SBR) biotreatment of pharmaceutical wastewater has been carried out to study the relationship between the treatment effects and pH,the temperatrue,the HRT and the effect of load of the sludge on the whole technology.The result shows that the BOD/CODCr of the wastewater is about 0.13 which meant the wastewater is difficult to be biodegraded;Through micro-electrolysis-anaerobic hydrolysis acidification pretreatment,the BOD/CODCr is increased to 0.63,and the biodegradability is improved greatly. When the CODCr load is kept at about 1 500 mg/L and 0.5 kg CODCr/(kg MLSS*d)，the HRT is 10 h,the effluent CODCr is under 200 mg/L and meet the requirement of the Second Grade Discharging Standard of pharmaceutical trade of GB8978-1996.
