厌氧膨胀颗粒污泥床反应器的工艺运行性能

Operation characteristics of expanded granular sludge bed reactor

从抗冲击负荷、变换水质和间断运行等三个方面来考察厌氧膨胀颗粒污泥床 ( EGSB)反应器装置的稳定性。结果表明 ,启动成功后的 EGSB反应器装置耐冲击 ,对不同水质的适应能力强 。

The EGSB reactor appears today as a robust technology and is by far the widely used high-rate anaerobic process, but there are some disadvantages, such as higher operation conditions. How the varied organic loading rate, different feeding water and intermittent operation exerted influences on the stability of EGSB reactor was studied. The results indicated that after the EGSB reactor was successfully started up, it operated smoothly in spite of the change of organic loading rate and feeding water in certain ranges; it was restarted up rapidly after intermitted a period of time.\;
