固定床复合生物反应系统处理生活污水同时硝化反硝化的研究

The Simultaneous Nitrification And Denitrification Researchment for Sewage Treatment byFixed Bed Composite Biological Reaction System

文章以固定床复合生物反应系统为基础,模拟小城镇生活污水为处理对象,研究了复合式膜生物反应器的同时硝化反硝化特性;同时对该系统的同时硝化反硝化机理进行了研究.实验结果表明：复合式膜生物反应器中DO在1.5～2.5 mg/L范围时,有利于系统的硝化反硝化同时顺利进行,另外,系统内碳源和溶液pH对硝化反硝化的进行有较大影响.

Based on the fixed bed composite biological reaction system as the foundation, to simulate the city sewage treatment. Study on the hybrid membrane bioreactorsimultaneous nitrification and denitrification characteristics of the system at the same time, the simultaneous nitrification and denitrification mechanism was studied. The experimental results showed that when the composite membrane bioreaetor＇s DO was in the range of 1.5-2.5 mg/L, the system was conducive to nitrification and denitrification and smoothly, in addition, the carbon source and the solution of pHsystem has a great influence on the nitrification and denitrification.
