超声清洗MBR生物膜—臭氧化技术在中水回用中的应用

The Application of Cleaning the BiomemBrane With Ultrasonics Technique and Ozone Oxidation Technique in the Recovery of Neutral Waste Water

超声清洗MBR生物膜—臭氧化技术,是在传统的二级生化污水处理技术的基础上,采用膜生物技术、臭氧化工艺和现代超声波清洗膜元件技术,进行生活污水回用处理的新兴技术。膜生物(MBR)技术具有出水水质好,一次性投资低,占地面积小,运行费用低等优点;利用现代超声波技术清洗膜元件,既可以彻底清除粘附在膜内、外壁上的污染物,又可以避免化学清洗对膜造成的危害,及清洗剂对环境的污染;采用臭氧化工艺,利用臭氧的强氧化性,可以彻底消除细菌、臭味、色度等可能对回用人群造成的危害,使处理后的水成为真正安全的回用水。

The technology of ultrasonics and ozone oxidation is new technique to clean the biomembrane（MBR） element using membrane technique, ozone oxidation technique and modern ultrasonics wave cleaning technique based on the tradional technology of disposing and recovering of class ￠ò biochemistry waste water. Membrane technique is of virtues as high quality filtrate, few lump-sum in.vestment, taking up not much land, lew motion cost, etc,. It can clean up the pollutants which sticked inside and outside the surface of the membrane, and can avoid the harm to membrane from the pollution to environment from the detergent, using modern ultrasonics technique. With strong oxidation of ozone, it can completely remove the possible harm to persons who use the recovery wastc water from bacterium, peculiar sell, colority, etc, by,using ozone oxidation technique, and make disposed waste water really safe and daily life water.
