摘要

研究了凹凸棒土预处理吸附强化混凝工艺对水中有机物的去除效果。试验证实凹凸棒土能起到吸附助凝作用,提升混凝沉淀工艺对水中有机物的去除率,TOC去除率可达45%左右,比水厂传统常规工艺的TOC去除率提高28.5%。凹凸棒土作为吸附剂,可应用于常规净水工艺的预处理工艺,增强净水工艺的去除有机物能力。
        The paper discussed the effect on removal of organic compounds in water coagulation process by the pretreatment technique, adsorption using attapulgite. The results showed that the attapulgite was helpful to the adsorption and coagulation process, which improved the removal rate of organic matter in water.The TOC removal rate can reach about 45 %, increased 28.5 % compared with the conventional water production process. Attapulgite adsorption as a new pretreatment technology can be applied to conventional water purification process to enhance the ability of organics removal in water.
