二级出水回用于电厂循环冷却水系统水处理剂的开发

针对某污水处理厂二级出水直接回用于电厂循环冷却水系统所产生的严重结垢问题,通过静态阻垢实验筛选出阻垢效果良好的复配配方,旋转挂片实验进行了该配方缓蚀性能的研究,并在自制的动态模拟实验对其现场条件下的缓蚀阻垢效果进行了验证,同时进行了环境毒性实验。结果表明:该水处理剂阻垢缓蚀性能良好、低磷无毒,是一种环境友好的水处理药剂。

Water Treatment Agent Developing of Secondary Effluent Directly Reused in Power Plant Circulating Cooling Water System

Secondary effluent of sewage treatment plant directly reused in power plant circulating cooling water system was the main cause of scale inhibition in the system.For this serious scaling problem,filter out the efficient compound formulation by static scale inhibition experiment.Study its corrosion inhibition performance by rotary coupon experiment.Test its scale and corrosion inhibition effect under the field condition by homemade dynamic simulation experiment,and test the environment toxicity at the same time.The result showed that,this water treatment agent gain the high scale and corrosion inhibition effect,with low phosphorus,non-toxic,friendly to environment.
