Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and particularly relates to a precise dosing system. Background Art

[0002] According to the sewage treatment effect of manual treatment, there are many particles in the sewage, and their sizes will change with the continuous addition of treatment chemicals (generally flocculants) during sewage treatment. As the treatment process progresses, the sizes of sewage particles will gradually coagulate and become larger. Therefore, the number of particles per unit space shows a trend from more to less. However, when the sizes of sewage particles become larger to a certain extent, the increase in treatment chemicals cannot make the particles become larger further, and adding more will be a waste, thus increasing pollution. At this time, the addition of treatment chemicals should be stopped or the addition amount of treatment chemicals should be reduced. When the sizes of sewage particles show a decreasing trend and theoretically tend to be stable, if no chemicals are added or the addition amount of chemicals is insufficient after a period of time, the flocculation effect will degrade and the particles will gradually become smaller naturally. Then, the addition of treatment chemicals should be restarted or the addition amount of treatment chemicals should be increased to achieve the purpose of reducing the usage amount of treatment chemicals.
