摘要
分析比较了国内外微孔曝气研究和应用实例,指出了目前微孔曝气技术的研究重点。同时,综合国内外研究人员的研究成果,分别叙述了曝气量、安装水深、安装面积、孔径、水质和气孔堵塞状况对微孔曝气充氧性能的影响,对不同影响因素的作用效果做了总结,并指出目前研究存在的问题。以期对污水处理厂曝气系统的优化提供借鉴,对拟采用微孔曝气法进行生态修复的研究提供参考。
In this review, some research and application examples of fine pore aeration are given, and the current research focus is pointed out. Besides, based on the domestic and foreign researches, the effects of aeration rate, installation depth, superficial area, pore diameter, water quality and pore dogging on oxygenation performance are summarized as well as the shortage of current research. It is expected to provide useful information for the wastewater treatment plants to optimize the aeration systems, and for the researchers who will take fine pore aeration as a ecological restoration technique.
