MSBR%脱氮除磷%反硝化
MSBR%脫氮除燐%反硝化
MSBR%탈담제린%반초화
MSBR工艺是连续流与序批操作相结合的新型生物脱氮除磷技术,由于它的后置反硝化设计,碳源不足制约了系统的脱氮效果。为改善这种状况,进行了将部分原水分流至缺氧区的试验。结果表明:引入原水后,缺氧区的反硝化速率常数提高了一倍,系统的反硝化速率和脱氮率相应提高。与此同时,分流造成了厌氧区的碳源不足,加之厌氧区的回流增加,引入了较多的硝酸盐,使磷的释放和过量吸收受到影响,除磷效果下降。另外,针对中间沉淀区暴露出的运行和设计问题提出了一些改进措施。
MSBR工藝是連續流與序批操作相結閤的新型生物脫氮除燐技術,由于它的後置反硝化設計,碳源不足製約瞭繫統的脫氮效果。為改善這種狀況,進行瞭將部分原水分流至缺氧區的試驗。結果錶明:引入原水後,缺氧區的反硝化速率常數提高瞭一倍,繫統的反硝化速率和脫氮率相應提高。與此同時,分流造成瞭厭氧區的碳源不足,加之厭氧區的迴流增加,引入瞭較多的硝痠鹽,使燐的釋放和過量吸收受到影響,除燐效果下降。另外,針對中間沉澱區暴露齣的運行和設計問題提齣瞭一些改進措施。

MSBR process is a newly developed biological nutrient removal technology,which combines continuous-flow reactor with SBR process.In order to improve nitrogen removal efficiency,the influent was introduced to anoxic zone and nitrogen and phosphorus removal efficiencies were studied.The results showed that the denitrification rate coefficient doubled and the nitrogen removal efficiency increased,while the phosphorus removal declined due to decreased carbon source and increased nitrate content in anaerobic zone.According to the problems appeared in the study,several modifications on operation and design of intermediate settling tank were proposed as well.
