在水处理的工艺流程中,如何提高混合反应构筑物的效率,是一个值得重视的课题。本文仅就混合反应设备中的液流状态对提高混凝效率的影响和具体措施等问题,提出几点粗浅的看法和建议。(一)正确认识、合理运用现有混凝理论的迫切性提出这个问题的出发点,在于现行设计中,大多忽略了国内外现有理论研究成果和一些比较符合客观规律的重要概念。致使目前不少类型的混凝构筑物的效率和效果一直没有显著提高,不适应提高沉淀,过滤效率和发展的现状。对于投药后混凝剂与原水的混合阶段,需要造成水流的剧烈搅动、混合、碰撞条件,使混凝剂在尽可能短的时间内(比如1分钟左右)能够均匀扩散,是提高混凝效率的重要措施,这是目前比较一
In the water treatment process, how to increase the efficiency of the mixed reaction structure is a subject worthy of attention. This article only puts forward some superficial views and suggestions on the effects of liquid flow conditions in mixed reaction equipment on improving coagulation efficiency and specific measures. (1) The urgency of correctly understanding and rationally using the existing coagulation theory The starting point of this issue is that in the current design, most of the existing theoretical research results at home and abroad are ignored and some important concepts that are more consistent with objective laws are ignored. As a result, the efficiency and effectiveness of many types of coagulation structures have not been significantly improved at present, and they are not suitable for improving the status of precipitation, filtration efficiency and development. For the mixing stage of the coagulant and raw water after administration, it is necessary to cause severe agitation, mixing, and collision conditions of the water flow, so that the coagulant can be uniformly diffused in as short a time as possible (for example, about 1 minute), which is to increase the coagulation efficiency. The important measure, which is currently a comparison
