Background

Rainfall runoff pollution is an important source of water pollution, particularly early-stage rainfall runoff, often carries a large amount of solid suspended substances, is a pollutant, and simultaneously serves as a carrier, and performs biochemical actions by adsorbing and enriching other pollutants, so that water quality pollution is caused to the storage water. Many studies have shown that the main pollutants in runoff all have a significant positive correlation with the content of solid suspended matters, so that reducing the concentration of the solid suspended matters in runoff can effectively reduce the content of various pollutants. The solid-liquid hydrocyclone separator separates the two-phase medium from the suspension by utilizing the centrifugal sedimentation principle, so that a large amount of suspended solids in surface runoff can be effectively removed, and pollutants adsorbed on the surfaces of the solids can be removed at the same time. Because the cost is low, the equipment structure is simple, the treatment efficiency is high, and the additional occupation of land is not needed, the technology of utilizing the hydrocyclone to treat the initial rainwater is widely applied in the field of water environment protection. However, different water flow speeds and different suspended matter concentrations have a great influence on the separation effect of the hydrocyclone, and the separation efficiency of the hydrocyclone needs to be mastered according to specific flow and water quality conditions in actual engineering design, which is the key for reasonable scheme design.
