摘要
絮凝沉降技术在水处理工艺中是一项广泛应用的技术。它不仅可用于给水处理,还可用于工业废水处理。许多工业废水经絮凝澄清后可返回工艺过程使用。这样不仅充分利用了水资源,而且有利于保护环境,因而有明显的经济社会效益。本研究采用明矾(硫酸铝钾KAl(SO4)2.12H2O)作混凝剂,用云龙湖小南湖水分析表明,加混凝剂前,总悬浮物含量为260mg/l,加混凝剂后,总悬浮物含量为52mg/l,比原来降低了80%,絮凝澄清效果较好,而且药剂消耗费用低,经济、社会效益显著。
Flocculation settlement technology being one extensive use in the handicraft in water treatment.It may be not only used for water supply treatment,but also may be used for industrial sewage treatment.A lot of industrial sewage by that the clear queen of flocculation may return to procedure.Such not only has fully utilized water resource,beneficial to protecting the environment moreover obvious economic and social benefits,adopting KAl(SO4)2·12H2O as coagulant,analysis with minor south lake water of Lake Yunlong indicates,before adding coagulant,general suspension thing contents are 260 mg/l,after adding the coagulant queen,general suspension thing contents are 52 mg/l,compare have reduced 80%,clear effect of flocculation is fairly good,the medicament consumes and cost low,economic and social benefits,is notable.
