摘　　要：为了保证部分亚硝化工艺运行的稳定性,探究进水有机物对亚硝酸盐积累的影响,确定部分亚硝化工艺的适用情况,采用SBR反应器,通过调整进水有机物浓度,定期对反应器出水有机物及氮元素含量进行检测。部分亚硝化工艺的进水COD质量浓度不宜大于150 mg/L,在此条件下,部分亚硝化工艺能获得较好的NH_(4)^(+)-N去除效果和NO_(2)^(-)-N积累效果。进水存在有机物的条件下,亚硝化反应中出现了氮损失的问题,COD的质量浓度过高不利于反应器内有机碳源的去除。In order to ensure the operational stability of partial nitrification process,investigate the influence of influent organic matter on nitrite accumulation,and determine the applicability of partial nitrification process.Using SBR reactor,the organic matter concentration in the influent was adjusted,and the organic matter and nitrogen content in the effluent of the reactor were regularly detected.The appropriate influent COD concentration for partial nitrification process should not exceed 150 mg/L.Under these conditions,partial nitrification processes could achieve better NH_(4)^(+)-N removal and NO_(2)^(-)-N accumulation effects.Under the condition of organic matter in the influent,there was a problem of nitrogen loss in the nitrification reaction.The high mass concentration of COD was not conducive to the removal of organic carbon sources in the reactor.
