| 摘 要： | 为了研究低DO浓度下对污染物的去除效果,采用SBR反应器,通过缺氧/好氧(A/O)的运行方式,考察了好氧段DO的平均值为1 mg/L时系统的除污效果,同时与好氧段DO平均值为2mg/L时系统的除污效果进行了对比.结果表明:在低DO浓度下,SBR工艺出水COD < 40mg/L,系统对COD的去除率在90%左右,对COD的去除效果略高于正常DO值条件下的;低DO浓度下,系统对氨氮的去除率在90%左右,对氨氮的去除效果低于正常DO值条件下的,但出水氛氮仍可保持在5 mg/L左右;系统的硝化反应速度较慢,反应结束时亚硝酸盐氮积累率为37%;NO--N生成速率与NH+-N氧化速率之比与DO浓度呈较好的线性关系;DO浓度对正磷酸盐的去除效果影响较小,系统对正磷酸盐的去除率＞90%,出水正磷酸盐浓度＜0.5mg/L;出水非常清澈,镜检可见丝状菌. |

| Abstract: | In order to study the pollutant removal efficiency under low DO,the pollutant removal efficiency at mean DO value of 1 mg/L in aerobic zone of sequencing batch reactor(SBR) operated in anoxic/aerobic(A/O) mode was investigated and compared with that at mean DO value of 2 mg/L.The results show that under low DO,the effluent COD is less than 40 mg/L,the COD removal rate can reach about 90%,and the COD removal efficiency is slightly more than that under normal DO.The ammonia nitrogen removal rate can reach abo... |
