改进SBR工艺运行方式强化脱氮除磷的效果

Improvement of SBR Process to Enhance Denitrogenation and Dephosphorization

由于传统序批式活性污泥法SBR处理工艺的局限性,当要求同时进行有机物、氮和磷的去除时,基本的运行方式虽在有机物的去除方面可达到较为满意的处理效果,但难以达到满意的脱氮除磷效果。通过对SBR法运行工况分析后提出了兼有脱氮功能、除磷功能及同时具备脱氮除磷功能的3种不同运行方式的改进流程,从而在不改变原有SBR反应池主体结构的基础上可满足不同尾水排放标准的要求。

You know traditional .sequencing batch reactor activated sludge ptocess is hard to remove organic matters, nitrogen and phosphoric at the same time. Through analyses on sequencing batch reactor method, three kinds of different running methods of improvement are put forward, that is denitrogenation or dephosphorization and meanwhile denitrogenation and dephosphorization, so requirements of different discharge standards can be met without changing the body structure of original sequencing batch reactor.
