| 摘 要： | 坡缕石粘土生产活性白土的过程中产生的酸化废液会对环境造成严重污染,利用此废液,通过加入浓碱在一定条件下聚合制备了聚合氯化铝铁,最佳聚合pH值为4.0,所得产品基本符合GB15892-2003水处理剂国家标准.混凝实验结果显示,在480 mg/L的投药量下聚合氯化铝铁对自配水的浊度去除率最高可达98.3%,且适应的pH值范围较宽,处理效果优于其他常用絮凝剂.

| Abstract: | The wastewater of palygorskite clay acid activation causes serious env
ironmental pollution during the production of fuller''s activated earth. Such was
te water was used by the authors to prepare polymerized aluminum-ferrum chloride
(PAFC) through the addition of high concentration of alkali under certain condi
tions. The optimal pH in the process of the preparation of PAFC was 4.0, and the
product obtained can basically meet the State Water Treatment Agent Standard of
GB15892-2003. With the addition amount of 480 mg/L of PAFC, the removal rate of
turbidity reached 98.3% for the synthetic water, and the operation could be adapted to a relatively wide pH range, suggesting that the treatment effect is bett
er than that of the other commonly-used flocculants. |
