【摘要】 依据分形理论,针对混凝过程中原水水质、水量的变化,考察了絮凝体分形维数与混凝剂投量和沉后水浊度间的变化关系。结果证实,分形维数的变化能够很好地反映絮凝程度及混凝处理效果,从而为建立以分形维数作为主控特征参数的混凝投药系统提供了依据,并通过大量的基础试验为分形维数模型控制提供了参考。更多还原

【Abstract】 With respect to the variation in raw water quality and quantity in coagulation process, investigation was made on the relations among fractal dimension of aggregated floc, coagulant dosage, and settled water turbidity. The result shows that variation in fractal dimension can make good response to flocculation level and treatment effect, and thus providing basis for setting up the coagulant dosing system with fractal dimension as the main control parameter, and a lot of basic experimental data were offered for establishing the fractal dimension control model.更多还原
