Discussion on Simulation Rotational Speed of Coagulation Jar Test

Abstract:

According to the characteristic of mixing and flocculation of water plant, the calculation formula of the simulation rotational speed of agitator was proposed for the coagulation-flocculation jar test of optimum dosage, which was based on the basic principle that the velocity gradient of production is equal to that of experiment. Obtained the calculation formula for related parameters about coagulation agitator through the determination of the actual production velocity gradient and combined with the coagulation jar test data in laboratory, such as the power consumption of the paddle boards; the proportional coefficient of coagulation agitator and the agitation speed etc. The result shows that the experiment simulation according with the effect of practical produce of water plant can provide the reliable optimum dosage of coagulant for the practical production. This research has a great signality to waste-water treatment, Results not only have great economic benefit, but also can achieve a certain ecological benefit, accorded with the demand of developing low carbon environmental protection.
