Description

一种高悬浮有机废水的处理方法
技术领域
本发明涉及一种废水的处理方法,特别是涉及一种高悬浮有机废水处理方法。
背景技术
工业废水是指工业生产过程中产生的废水和废液,其中含有随水流失的工业生产用料、中间产物、副产品以及生产过程中产生的污染物。按工业废水中所含主要污染物的化学性质分类,有含无机污染物为主的无机废水和含有机污染物为主的有机废水。例如电镀废水和矿物加工过程的废水是无机废水,食品或石油加工过程的废水是有机废水。按工业企业的产品和加工对象可分为造纸废水、纺织废水、制革废水、农药废水、冶金废水、炼油废水等。按废水中所含污染物内主要成分可分为酸性废水、碱性废水、含酚废水、含铬废水、含有机磷废水和放射性废水等。
化学工业废水具有毒性大、成分复杂的特点,是水处理中的难点。尤其是高悬浮的有机废水,治理难度更大。
发明内容
本发明的目的在于克服现有高悬浮有机废水治理效果差的缺点,通过试验改进,提供一种有效的高悬浮有机废水的治理方法。
本发明的目的是通过以下技术方案实现的:
一种高悬浮有机废水的处理方法,该方法包括以下步骤:
(1)首先用稀硫酸将废水pH值调节到7~7.5;
(2)在废水中加入0.1%~0.5%的聚合氧化铝和0.2%~1.0%的有机硅,加热至45~55℃;
(3)静置15分钟,悬浮物即可有效沉淀。
本发明的优点与效果是:
本发明的制作工艺简单,成本低,治理高悬浮效果好。
具体实施方式
实施例1
对悬浮物含量在1%的有机废水,首先用稀硫酸将废水pH值调节到7~7.5。在废水中加入0.1%的聚合氧化铝和0.2%的有机硅,加热至45℃~55℃。静置15分钟,悬浮物即可有效沉淀,上层水中有机悬浮物含量可降至0.05%以下。
实施例2
对悬浮物含量在3%的有机废水,首先用稀硫酸将废水pH值调节到7~7.5。在废水中加入0.3%的聚合氧化铝和0.6%的有机硅,加热至45℃~55℃。静置15分钟,悬浮物即可有效沉淀,上层水中有机悬浮物含量可降至0.1%以下。
实施例3
对悬浮物含量在5%的有机废水,首先用稀硫酸将废水pH值调节到7~7.5。在废水中加入0.5%的聚合氧化铝和1.0%的有机硅,加热至45℃~55℃。静置15分钟,悬浮物即可有效沉淀,上层水中有机悬浮物含量可降至0.2%以下。
