  • 摘要: 为了比较西北地区沉淀与气浮工艺处理地表水效果的异同，并为水厂实际运行提供意见和参考，在中试条件下，以优化高锰酸钾预氧化的方式，降低前加氯的投量，增加助凝剂中高锰酸盐的投量和投加比例，通过系统实验筛选，发现对于混凝沉淀和混凝气浮工艺当PAFC投加量分别为16、9 mg·L-1，助凝剂为8、4.5 mg·L-1时，2种工艺出水浊度均能控制在1 NTU左右。对于沉淀和气浮工艺，当PAFC投加量为16 mg·L-1，预氯化投氯量为0.4 mg·L-1，助凝剂中高锰酸钾比例为1.0%时，对水合三氯乙醛（CH）的形成控制效果最佳且相对比较经济，同时也可以更好地控制其他水质指标。
    Abstract: In order to find the similarities and differences between sedimentation and dissolved air flotation processes for water supply treatment, and to give useful recommendations to a water treatment plant in Northwest China, we reduced the dosage of chlorine in pre-chlorination and increased the proportion of potassium permanganate as a coagulant aid to optimize the treatment process at pilot scale. Through system testing, we found that when the coagulant dosage was 16, 9 mg·L-1 and coagulant aid dosage were 8, 4.5 mg·L-1, the effluent turbidity of the two process was almost 1 NTU. Considering the formation of CH, and the other water-quality indexes being controlled, optimal operating conditions and parameters were determined. The dosage of PAFC was 16 mg·L-1, the best dosage of chlorine in pre-chlorination was 0.4 mg·L-1, and the optimal ratio of potassium permanganate in the coagulant aid was 1.0%.
