降低饮用水中残余铝浓度研究

摘要

By the study of coagulation and filtration experiments, analysis is made of the coagulation conditions on the impact of residual aluminum in drinking water, such as rapid mixing intensity, slow mixing intensity, pH, temperature etc; the filter thickness is on the impact of residual aluminum in drinking water. Experimental results show that when the coagulant dosage is constant, by controlling the coagulation conditions and the appropriate filter thickness can reduce the residual aluminum content in drinking water.%通过混凝实验及过滤实验研究，分析了混凝条件如快速搅拌强度、慢速搅拌强度，pH，温度等对饮用水中残余铝含量的影响；研究了滤柱滤层厚度对饮用水中残余铝含量的影响。实验结果表明在混凝剂投加量一定时，通过控制混凝条件及合适的滤层厚度能够降低饮用水中残余铝含量。
