Abstract采用PDA(Photometric Disperse Analysis)和有机物表观分子量分级、有机物化学极性分级技术从絮体形成过程、絮体表现、有机物分子水平变化等方面研究了臭氧预氧化对混凝过程的影响;并对比了不同混凝剂在预臭氧条件下的混凝过程和效率.结果表明:臭氧预氧化对混凝过程有复杂的影响,其剂量和水体有机物特征决定了其对混凝的整体影响效果.有机物分级显示,臭氧化对有机物结构有重要影响,导致有机物极性、亲水性组分含量大幅提高(36.7%),小分子量组分(<10×103)大幅增高(100%左右);但总的DOC去除率不高(3.28%).对PACl而言,在中、低剂量(O3/TOC<0.7)下,臭...
