摘要
采用厌氧-好氧法处理豆奶废水,分析温度在35℃时好氧运行中曝气时间对污染物去除效果的影响.实验结果表明,好氧进水COD在420～560 mg/L之间,曝气3 h,其COD去除率可达80%以上,NH4+—N、PO43-—P去除率都可达到90%以上.采用厌氧-好氧法处理豆奶废水是实际可行的.
The removal of soy milk wastewater was investigated by anaerobic-aerobic method in this experiment. When temperature was at 35 ℃, the impact of aeration time in aerobic running on the pollutant removal efficiency was analyzed. Experimental results showed that aerobic influent COD was between 420 - 560 mg/L, after aeration for 3 h, the COD removal rate could reach more than 80% , the removal rate of NH4 ＋-N and PO43-P could be more than 90%. The anaerobic-aerobic method for soy milk wastewater treatment is practica- ble.
