Description

煤焦油生产中的污水处理剂
技术领域
本发明属于水、废水、污水处理技术领域,具体涉及到悬浮杂质的絮凝或沉淀。
近些年来,随着我国国民经济的快速发展,石油资源日渐短缺,已成为制约我国经济发展的关键因素之一。煤焦油是由烷烃、芳香烃、胶质和沥青质组成的有机混合物,用煤焦油替代石油,在高温、高压条件下,经加氢改质生产汽油和柴油技术有了较快发展。煤焦油是炼焦工业、煤化工及煤气化等工业的重要副产品。随着我国钢铁、化工等产业的日益壮大,焦化工业也随之迅速发展起来,目前我国已成为世界最大的焦炭和煤焦油生产国,煤焦油产量的不断增加,促进了煤焦油加工燃料油产业的发展,并具有显著的经济效益、社会效益和环境效益。
在煤焦油的生产过程中,需要水蒸气,产生废水,为了减少环境污染,将工业废水进行循环使用,并采用废水制备水蒸气,由于生产过程中的废水中含杂质、粉煤灰较多,在锅炉内出现结垢以及污染物沉淀,增大了燃料的消耗,浪费了能源,加大了生产成本。
目前在工业废水的处理中所用的污水处理剂有硫酸亚铁、氯化亚铁、硫酸铝、碱式氯化铝等无机处理剂,聚合氯化铝、聚合硫酸铁高分子处理剂。不少无机处理剂有强烈的腐蚀性很容易腐蚀设备,对于工业污水、油田污水、含重金属离子污水的处理很不适用。
