摘要

通过COD浓度对A／ASBR反硝化除磷脱氮系统的影响试验表明，过高或过低的COD都不利于反硝化除磷系统的正常运行，当COD=220～300mg／l时，可以获得较为理想的处理效果。发现了缺氧段残存的外碳源有机物和厌氧储存的胞内碳源PHB对反硝化除磷过程的影响；试验结果进一步表明以PHB为碳源的反硝化除磷过程中，PHB的消耗与反硝化除磷脱氮具有良好的相关关系，并且2mgNO3^--N的转化可以促进1mg PO4^3--P的吸收。

Abstract

By the study of the influence of COD concentration on denitrifying phosphor removal of A/ASBR (anaerobic/ aerobic sequence bioreactor)

it was shown that the favorable treatment effect had been gained with the COD concentration between 220 and 300mg/l; the higher or lower concentration of COD was unfavorable to the work of the system. In our test

it has been confirmed that the rudimental carbon resource organism and cell depositor PHB deposited in anaerobic stage has a significant influence on the process of denitrifying phosphorous removal. The better correlation has been observed also between the consumption of PHB and denitrifying phosphorous removal when the use of cell depositors PHB as carbon resource is concerned. It indicates that the deoxidization of 2 mg nitrate may accelerate the absorption of 1 mg phosphorous.
