【摘要】 针对低浊度的闽江原水进行了混凝剂和助凝剂的选择试验。采用的混凝剂有硫酸铝、聚合氯化铝;采用的助凝剂包括阳离子型、阴离子型和非离子型三种。试验研究表明:将聚合氯化铝与阳离子型助凝剂配合使用进行闽江原水处理,生成的矾花大、密实、大小均匀、沉淀快,沉淀水的浊度低,对原水的pH值影响小,比单独使用混凝剂效果更好,成本更低。更多还原

【Abstract】 The selecting coagulant and coagulant aids tests for treatment of low turbidity Min River primary water were proceeded in this paper.The coagulants adopted include aluminum sulfate and polyaluminum chloride.The coagulant aids adopted include anionic,cationic and nonionic products.The test study reveals that if polyaluminum chloride coagulant and cationic type coagulant aids are used to treat low turbidity Min River primary water,the floccule is big,dense and even,and deposits quickly;the turbidity of water can be reduced significantly;the effect of the treatment method on pH value can be ignored.Comparing with the conventional method,namely only coagulant is applied,the method provided in this paper can achieve better effects and lower cost.更多还原
