摘要：

影响水的混凝效果因素众多,如 :浊度、色度、碱度和 pH等,难以直接确定合适的混凝剂及加注量,而混凝沉淀试验是对水的混凝沉淀研究及指导生产的最有效方法。文章介绍混凝沉淀试验标准编制宗旨、主要内容及有关问题的说明。

Abstract:

The coag ulation effect of water is inf luenced by a number of factors and there is no way to determine the chemical dose needed according to the turbidity color alkalinity, or pH of the raw water. The beaker test is the most practical way to do coagulation-flocculat ion and sedimentation treatment research and to give direct ions in production. The compilation purpose, major contents and explanations of related questions of the standard for coagulation-flocculat ion and sedimentat ion beaker test are introduced.

Key words: coag ulation-flocculation, sedimentation, standard
