厌氧/特异性移动床生物膜反应器(A/SMBBR)组合工艺处理农药含酚废水

采用SDC-03型生物载体作为填料，考察厌氧-特异性移动床生物膜反应器对农药含酚废水中酚的去除效果，并探讨水力停留时间（HRT）、溶解氧（DO）、进水酚浓度、pH值4个影响因素对反应器处理效果的影响。实验结果表明：在水温20~35℃，进水pH为7.0~8.5，酚浓度为36.70~86.56 mg·L-1，系统水力停留时间（HRT）为10 d的操作条件下，酚可稳定在2 mg·L-1以下，运行后期酚浓度可降到0.5 mg·L-1以下，平均去除率为98.24%，最高可达99.56%。出水水质满足《污水综合排放标准》（GB 8978-1996）的排放标准。

Treatment of pesticides phenol-containing wastewater by anaerobic-specific moving bed biofilm reactor(A/SMBBR) combined process

This study examined the removal of phenol from pesticide-containing wastewater by an anaerobic-specific moving bed biofilm reactor (A/SMBBR)using the biological carrier SDC-03 as the filler. Four influencing factors were investigated:hydraulic residence time (HRT),dissolved oxygen (DO),phenol concentration of the influent,and pH. The results showed that,under a reaction temperature of 20 to 5℃,pH of 7.0 to 8.5,influent phenol concentration of 36.70 to 86.56 mg·L-1,and HRT of 10 d,the phenol concentration of the effluent remained under 2 mg·L-1,sometimes reaching less than 0.5 mg·L-1. An average phenol removal rate of 98.24% could be achieved,and the maximum removal rate was 99.56%. The effluent quality satisfied the requirements of the Integrated Wastewater Discharge Standard (GB 8978-1996).
