摘要
研究采用两相厌氧生物技术处理环氧树脂生产废水。试验结果表明:经过AMBR和EGSB反应器处理后,COD去除率达到91%,SS去除率达到67%;进水在产酸器AMBR反应后,pH值由6.8降至5.86,VFA由1265 mg/L升至3862 mg/L,酸化效果较好;经产甲烷器EGSB反应后,pH值和VFA分别为7.61和206 mg/L,产甲烷效果良好;经过后续工艺SBR处理后,出水符合国家污水综合排放标准。
The two-stage anaerobic biological technique is introduced to treat wastewater from production of epoxy resin. The experimental results are as follows: the COD removal rate reached 91% and the suspended solids(SS) removal rate was 67% after treatment by the anaerobic migrating blanket reactor(AMBR) and the expanded granular sludge bed(EGSB) reactor the pH value of the effluent water decreased from 6.80 to 5.86 and volatile fatty acids(VFA) varied from 1 265 mg/L to 3 862 mg/L when influent water was treated by the AMBR reactor, and the acidification effect was preferable; the effluent water from the AMBR was treated by the methanation reactor(EGSB reactor) and the efficiency of methanation was favourable, and the pH and VFA became 7.61 and 206 mg/L respectively. Then the water was further treated by the SBR in the continuing process and the effluent water met the demands of National Integrated Wastewater Discharge Standard.
