摘要
采用生活污水启动以升流式反应系统实现的UCT工艺系统。研究了启动过程中系统对COD、NH4+-N、NO3--N、NO2--N、PO43--P等指标去除率及出水质量浓度的变化情况。试验结果表明,UCT工艺稳定运行后,系统对COD的去除率达到85%以上;对NH4+-N去除率可达到97%以上,甚至有时去除率达到100%,NH4+-N零排放;对TN的去除率稳定在75%左右;对PO43--P的去除率达到为80%。除总磷只达到一级B标准外,试验出水的水质指标均能满足城镇污水处理厂污染物排放标准(GB 18918-2002)中一级A的要求。
The UCT process system was started up using sewage.The effect of the device during the start-up process on the removal and the change of COD, NH4＋-N, NO3-N, NO2^--N, PO4^3--P.The results showed that： When UCT process was stable, the system removal rate of COD was above 85%; the removal rate of NH4＋-N was above 97%, and even sometimes the removal rate was 100%;the removal rate of TN was about 75%;the removal rate of PO4^3-P was 80%.Except TP only reached level B standards, all the other water quality of the effluent from the UCT process can meet the emission standards （GB 18918--2002） in the level A requirements.
