摘　　要：开展了ClO2预氧化与PDM复合药剂联用提高常规处理工艺除藻效果的试验研究。结果表明,对于藻类数为1.3×108个/L、浊度为10.32～15.50 NTU、温度为27～30℃的黄河下游引黄水库水,当ClO2投量为1.0 mg/L、PDM复合药剂投量为60 mg/L时,滤后水浊度能降至0.2NTU以下,对CODMn的去除率达到46.6%,对藻类的去除率高达99%以上。ClO2预氧化与PDM复合药剂联用技术是强化常规工艺处理高藻水库水的有效措施。Experiments were carried out to improve algae removal effect in conventional treatment process by jointly using ClO2 pre-oxidation and PDM composite coagulants. For the reservoir raw water in the lower reaches of Yellow River with algae content of 1.3 × 10^8 ind./L, turbidity of 10.32 to 15.50 NTU, temperature of 27 to 30 ℃, when the dosage of ClO2 and PDM composite coagulants are 1.0 mg/L and 60 mg/L respectively, the turbidity of filtered water can be reduced to below 0.2 NTU, and the removal rates of CODMn and algae reach 46.6% and above 99% respectively. The combined process of ClO2 pre-oxidation and PDM composite coagulants is an effective technology for treatment of the reservoir raw water with high algae
