活性炭吸附-光催化氧化深度净水工艺实验研究

以光催化氧化作为活性炭吸附工艺出水通常存在的亚硝酸盐、余氯与细菌总数超标等问题,并能去除铁穿透炭层的极性短链有机污染物,使出水达到《饮用净水水质标准》（CJ94－1999）。与目前常用的活性炭－反渗透组合工艺相比,该工艺具有可保留水中有益的矿物成分的特点,具有良好的应用前景。

Experimental Study on Advanced Purification Technology of Activated Carbon Adsorption-Photocatalytic Oxidation

Employing photocatalytic oxidation as a follow up process for advanced treating of activated carbon adsorbed drinking water, then the usually existing water quality problems concerned activated carbon adsorption, such as nitrite, chlorine residual and bac-teria counts overproof could be solved satisfactorily. And polar short chain compounds,which broke through the carbon bed easily, were decomposed efficiently.Thus,the effluent of the combined process could meet the"Purified Drinking Water" Standard. Compared with popular acti-vated carbon-reverse osmosis combined process, the pro-posed technique has an important advantage of reserving profitable minerals in water
