【摘要】 本文对韶关市自来水总公司净水剂厂生产的液体ＰＡＣ应用的有关参数进行了试验研究。结果表明：１）液体ＰＡＣ的最佳储存浓度应为其Ａｌ２Ｏ３的含量在４％以上。２）投加液体ＰＡＣ的稀释比，当原水浊度不大于５００ＮＴＵ时，最佳值为１∶１５，当原水浊度大于５００ＮＴＵ时，最佳值为１∶１２。更多还原

【Abstract】 Abstract: Liquid PAC (poly aluminum chloride) produced by the coagulant plant of Shaoguan Water Company in Guangdong province was tested experimentally to examine some parameters related to its application. The results obtained are follows: 1) the optimum storage concentration of liquid PAC must be 4% higher than its Al2O3 content. 2) The dilution ratios of liquid PAC dosage must be 1:15 and 1:12 when the turbidity of raw water up to 500 NTU and higher than 500 NTU respectively.更多还原
