摘要
采用好氧颗粒污泥SBR工艺(序列间歇式活性污泥法)处理高浓度氨氮废水,结果表明工艺具有良好的COD和氨氮去除效果。在进水COD质量浓度为800mg/L,氨氮质量浓度为50mg/L的条件下,COD与氨氮的去除率均随处理时间增加而上升,但COD的去除效率远高于氨氮,以反应4小时计,氨氮去除效率约为55%,而COD去除效率达到90%左右。平稳运行下亚硝酸盐与硝酸盐浓度随时间的变化始终稳定在较低的水平。
Some methods dealing with high concentration of ammonia nitrogen waste by aerobic granular sludge were introduced.The results showed that aerobic granular sludge had good efficiency of COD and ammonia removal at the condition of 1000mg/L COD and 50mg/L NH+4-N,after 4h,and COD and NH+4-N removal efficiency was 90% and 55%,respectively.
