摘　　要：通过对混凝沉淀烧杯试验方法的改进,即将设定参数速度梯度G值和水力停留时间T值进行有效组合,研究了混凝沉淀烧杯试验与反应池中混合、絮凝和沉淀工艺运行的相似性。结果表明改进的方法可以简单有效的得到较为精确的运行参数,对生产具有实际指导意义。By improving the method of coagulation-flocculation and sedimentation beaker test, w hich makes effective combination of the set parameters of the velocity gradient G and the hydraulic retention time T, this paper explores similarities between the mixing, flocculation and sedimentation process in the reaction pool and the coagulation-flocculation and sedimentation beaker testing. Results show that the improved method can simply and effectively get the accurate operating parameters, providing practical reference for production.
