| 摘 要： | 采用石灰软化-絮凝法处理华南地区某水厂地下水硬度。在实验室进行静态烧杯试验研究,考察石灰投加量、混凝剂投加量、沉淀时间和过滤条件对试验效果的影响。试验结果表明,石灰投加量为180~240 mg/L,PAC投加量为15~30 mg/L,沉淀时间小于30 min,滤料粒径为0.5 mm、滤速为10 m/h时处理效果最佳。

| Abstract: | The study determined the treatment of hardness of groundwater by lime softening coagulation-flocculation in a waterworks in South China. Static jar tested the influence of lime dosage, coagulant dosage, sedimentation time, and filtration conditions on the test results. The test results show that when the lime dosage is 180-240 mg/L, PAC dosage is 15-30 mg/L, precipitation time is less than 30 rain and the filter material particle size is 0.5 mm, filter speed is 10 m/h, the best treating result will be obtained. |
