引言斜板斜管沉淀技术在国内外已获得了广泛的应用。国内在处理低浊度水方面已有较多的经验;而在处理高浊度水方面则仍感经验不足。由于高浊度水水质变化较复杂,为解决处理技术上的困难,要求事先进行动水试验,以取得必需的工艺参数,如斜板斜管内的轴向流速,进水、出水及排泥流量,出水浊度及排泥浓变,以及混凝沉淀所需的药剂品种和投量等,作为设计的依据及以后试运转的参考。目前国内所进行的一些试验多属半生产性的动水试验,试验效果较好,但在选择有高浊度水水源如黄河等处进行动水试验,从
Introduction The sloping ramp tube precipitation technology has been widely used at home and abroad. Domestically, there is more experience in dealing with low turbidity water, and there is still insufficient experience in dealing with high turbidity water. Due to the complex changes in water quality of high turbidity water, in order to solve the technical difficulties in processing, advanced water tests are required to obtain the necessary process parameters, such as the axial flow velocity in the sloping plate inclined pipe, inlet, outlet and discharge flow The effluent turbidity and sludge concentration, as well as the types and dosages of the reagents required for coagulation and sedimentation, are used as the basis for the design and for future reference. At present, some of the tests conducted in China are mostly semi-productive hydrodynamic tests. The test results are good, but in the selection of a high turbidity water source such as the Yellow River, the hydrodynamic test is carried out from
