| 摘 要： | 对新近合成的淀粉改性聚合硫酸铝絮凝剂POA降低太阳池中老卤水浊度的条件进行了优化。在老卤液盐度为402‰、pH为6.4、温度为18℃条件下,投加POA为3%(V/V)、400r/min下搅拌1min、200r/min下搅拌10min、70r/min下搅拌10min、沉降时间为90min时,絮凝剂对老卤液的降浊率可达97.8%,浊度降至1～2NTU。与常规的聚合氯化铝和聚合硫酸铝絮凝剂相比,POA对老卤水具有更优良的絮凝降浊能力,降浊率分别提高了62.2%和48.3%。POA处理后的老卤液能在太阳池中稳定运行60d,之后池中不同盐层浊度和叶绿素含量均有一定程度的升高,表明有藻类滋生。

| Abstract: | Starch modified and polymerised aluminium sulfate (POA), a newly synthesized flocculant, can reduce turbidity of bitten wastewater in the solar pond and optimisation of the operation conditions was investigated. Compared with traditional flocculants such as polymerised aluminium chloride or polymerised aluminium sulfate, POA can efficiently remove bittern turbidity and improve the efficiency by 62.2% and 48.3% respectively. The bittern treated by POA can stably run in the solar pond within 60 days and the increase of turbidity and chlorophyll after 60 days operation indicated the growth of some micro-algae. |
