Description
Technical Field

Background
The principle of the vortex flocculation reactor is as follows: when water flows through a large number of holes on the wall surface of the micro-vortex flocculator, countless micro-vortices are formed, and according to the modern coagulation theory, the micro-vortices are beneficial to migration and collision coagulation of fine particles in water, so that the reaction efficiency is improved. And because the micro-vortex flocculator is a hollow shell, the internal flow velocity is small, a large amount of floccules with larger particle diameters are accumulated and suspended in water in the micro-vortex flocculator, the suspended floccules are called sludge, and the sludge can absorb the fine floccules, namely contact flocculation.
