摘要

通过控制曝气量的方式研究了溶解氧对污泥减量系统除磷脱氮过程的影响。发现在低剂量2，4，5三氯苯酚（TCP）作用下，活性污泥的内源SOUR值增加，SBR系统的低DO状态持续时间增长，周期平均DO降低，形成了有利于同时硝化反硝化SND脱氮的低DO环境。综合考虑TCP浓度对污泥减量、除磷脱氮和污泥性能的影响，TCP浓度建议为2 mg/L，SBR周期平均DO值控制为2 mg/L。与对照系统相比，2 mg/LTCP污泥减量系统的曝气量增加了23%，剩余污泥排放量减少34.6%，出水水质与对照系统相当，实现了达标排放。表明低DO控制状态下、辅以排富磷污水除磷方式，TCP系统可以同时获得优异的除磷脱氮和污泥减量效果。

Abstract

The influences of dissolved oxygen (DO) on the removal process of nitrogen and phosphorous in a sludge reduction system had been studied by controlling aeration amounts. It was found that under the conditions of low doses of 2

5trichlorophenol (TCP)

endogenous sour values of activated sludge increased with the extension of low DO state duration in SBR system and the decrease of cyclic average DO

which led to a low DO environment favored the formation of simultaneous nitrification and denitrification(SND).TCP concentration was recommended as 2mg / L and cyclic average DO value in SBR system was kept at 2mg / L based on the impacts of TCP concentration on sludge reduction

removal of nitrogen and phosphorous and sludge performance. Compared with the control system

aeration amounts increased by 23% and the discharge of excess sludge decreased by 34.6%. The water quality in effluents was equivalent in the aeration sludge reduction system with 2mg/LTCP

which met the discharge standards. Therefore

it was indicated that the removal of nitrogen and phosphorous and sludge reduction can obtain excellent performance in TCP system under low DO state with removing Phosphrousrich sewage.
