摘要 反硝化过程中可利用的碳源包括快速生物降解物质、慢速生物降解物质和内源代谢物质,碳源的种类及数量对系统的脱氮效果有很大的影响.对上海某污水处理厂的水质测试研究表明:污水中快速生物降解碳源、慢速生物降解碳源以及内源代谢碳源的平均比反硝化速率分别为3.10 mgN/(gMLVSS·h)、0.81 mgN/(gMLVSS·h)和0.32 mgN/(gMLVSS·h);污水中的快速生物降解物质占总COD的9.26%~18.5%,慢速可生物降解物质占29.2%~34.6%;污水的反硝化脱氮能力主要由慢速生物降解碳源的含量来决定,占总硝氮去除量的一半左右;快速生物降解碳源反硝化的硝氮占20%左右,内源代谢占30%左右.
