本文分别以地表水和地下水为水源的水厂出水为研究对象 ,探讨了活性炭 -纳滤膜工艺对饮用水中总有机碳和可同化有机碳的去除效果及机理。结果表明 ,活性炭的吸附作用受其本身性质和有机物特性影响较大 ,去除能力有限 ;纳滤则可将水中总有机碳和可同化有机碳大都去除 ,确保饮用水的安全性和生物稳定性。两者的组合是获得优质饮用水的有效处理工艺。
In this paper, water effluent from surface water and groundwater are taken as the research object respectively, and the removal efficiency and mechanism of total organic carbon and assimilable organic carbon in drinking water by activated carbon-nanofiltration process are discussed. The results show that the adsorption of activated carbon is greatly affected by its own properties and organic compounds, and its removal ability is limited. Nanofiltration can remove most of the total organic carbon and assimilable organic carbon in water to ensure the safety and biological stability of drinking water. The combination of the two is an effective process for obtaining quality drinking water.
