应用中微孔曝气器的运行效果及分析

OPERATIONAL EFFECTIVENESS AND ANALYSES OF MICROPOROUS DIFFUSERS SYSTEM

总结国内４个曝气器生产厂家几种产品的单盘清水充氧性能试验和阻力测试的情况；分析应用ＷＺＰ型中微孔曝气器的效果和理论机理，提出进出水ＣＯＤＣｒ与ＢＯＤ５及出水ＣＯＤＣｒ与ＳＳ关系的线性方程，为生产运行和管理提供了科学参考依据；结果表明。

Oxygen transfer performances and resistance of each of several diffusers made by four diffuser production factories in China were tested and concluded in this paper,operational effectiveness and theoretical mechanism of WZP type microporous diffusers were analyzed,linear relationships between CODcr and BOD 5 contents of the influent and effluent,and between CODcr and SS contents of the effluent were set up,and a scientific basis of reference for the aerobic activated sludge processs operation and management was provided.Results obtained from both the test and the production show that dissolved oxygen contents and BOD 5 removals of the mixed liquor increased significantly.
