摘要: The impact of adding diatomite on the treatment performance slightly polluted algae-containing raw water using ozone pre-oxidation and polyaluminum chloride (PAC) coagulation was investigated. Results demonstrated that addition is advantageous due to reduction PAC dose (58.33%) improvement removal efficiency algae, turbidity, dissolved organic matter (DOM) in water. When concentration 1.0 mg L−1 dosage 2.5 mg L−1, rates UV254, TOC were improved by 6.39%, 7.06%, 6.76%, 4.03%, respectively, with 0.4 g L−1 diatomite. It has been found DOM presented Pearl River mainly consisted small molecules ( 50 kDa). After (0.4 g L−1), additional 5.77% 14.82% UV254 for 50 kDa) could be achieved, at an ozo...
