摘　　要：通过辣木种仁净水剂与常用化学净水剂净水效果比较研究,表明辣木种仁净水剂有很好的净水效果,净水效率与聚合氯化铝相当,能使水的混浊度降到世界卫生组织饮用水标准以下(浊度≤5FTU),可作为化学净水剂的替代品使用;辣木种仁和辣木油渣都可作为净水剂使用,二者净水效果差异不显著,从净水成本和综合利用考虑,选用辣木油渣作为混水净水剂更加经济合理;当混水浊度为150.6FTU时,辣木油渣净水的最佳剂量为每升混水中加入0.2g辣木油渣粉。A comparative study of Moringa oleifera Lam, seeds and chemicals as coagulant demonstrated that M. oleifera seeds was effective in purifying water, the effect was similar to polyaluminium chloride. As a natural, safe coagulant, M. oleifera seeds was able to reduce turbidity of water to below the World Health Organization＇s guideline value of ≤5 FFU for drinking water, so it can be used to substitute the chemical coagulants in water treatment. Both M. oleifera seeds and the oil cake can remove turbidities of water, there was no obvious difference in terms of their effect and thus both can be used for water purification. In concern of the cost and comprehensive use of the seeds, the oil cake was more economic and reasonable. When the turbidity of water was 150.6 FFU, the optimal dosage of M. oleifera seeds for water purification was 0.2 g seeds per l L water.
