采用微气泡纯氧曝气技术处理工业废水

Application of micro-bubble pure oxygen aeration technique to the treatment of industrial wastewater

纯氧曝气活性污泥工艺处理工业废水在国外已有长足进展。近年来随着我国国民经济迅猛发展,污水处理的要求也越来越高,为解决目前污水处理跟不上国民经济发展的问题,用纯氧曝气活性污泥工艺取代现有的空气曝气活性污泥工艺不失为一个良策。论述了纯氧曝气活性污泥工艺的优越性,比较了各种制氧方法和曝气方法,指出采用PU-8吸附剂变压吸附制氧和敞开式微气泡纯氧曝气活性污泥工艺有较好的发展前景,应尽快加以推广应用。

The pure oxygen aeration process of activated sludge for the treatment of industrial wastewater has already made considerable progress abroad. The requirements for wastewater treatment is getting higher and higher, as the national economy in China is developing rapidly. To solve the problem that the wastewater treatment couldnet keep pace with the development of the national economy, the replacement of the pure oxygen aeration activated sludge for the present aeration activated sludge is a good measure. The advantage of the pure oxygen activated oxygen aeration is discussed, and various oxygen making methods and aeration methods are eompared. It shows that the processes of oxygen making by pressure changing adsorption with adsorption agent, PU-8, and the opened-style micro-bubble pure oxygen aeration activated sludge technologies have better developing foreground. This method should be popularized and applied as quickly as possible.
