以往设计反应池是按水流速度(或搅拌机叶轮线速度)和反应时间两个参数考虑的。近年来,国内外改用速度梯度G值或G值与反应时间T的乘积GT值来作为反应设计的依据。后者虽较前者有所进步,但都是强调“要有足够的反应时间”。根据实践观察和理论分析,反应是否充分,不能只以时间长短来衡量。如果水体没有合理的运动状态,虽有足够的反应时间,絮凝效果也并不一定有所提高。故欲提高混凝设备的效率和效果,就必须跳出 In the past, the design of the reaction cell was based on the two parameters of the water flow rate (or mixer impeller linear velocity) and reaction time. In recent years, at home and abroad, the G value of the velocity gradient or the product GT value of the G value and the reaction time T has been used as the basis for the reaction design. Although the latter has made some progress compared with the former, it all emphasizes “there must be enough reaction time.” According to practical observation and theoretical analysis, whether the response is sufficient cannot be measured only by the length of time. If the water body does not have a reasonable movement state, although there is sufficient reaction time, the flocculation effect does not necessarily increase. Therefore, if you want to improve the efficiency and effectiveness of your coagulation equipment, you must jump out.
