摘要
基于已有的研究成果通过混凝烧杯试验就二次凝聚法的凝聚剂投加量比例、快速混合强度和pH范围等因素对原水TOC去除效果的影响进行了研究。试验结果表明,将常规凝聚的加药量等分2次投加能取得最好的原水TOC去除效果,高混合强度有利于去除原水TOC,二次凝聚的最佳pH范围与原水pH范围一致。
The influencing factors on TOC removal in two-stage coagulation process, including the
dosage of coagulants, the mixing intensity and the pH range of the raw water are researched by means of
jar test. The experimental results show that the best dosage of flocculant for normal coagulation is
divided into two equal portions and added at two times. High mixing intensity is helpful for TOC
removal. The best pH range at the process is accordant with that of the raw water.
