Description

[0002] In the sewage treatment process, the use of flocculants plays an important role in improving the dewatering performance of sludge, and the flocculants play a key role as "colloid agglomerator" and "pollutant remover" in sewage treatment. Its core role is to agglomerate small suspended particles, colloids and other pollutants in wastewater into large flocs through physical and chemical action, thereby facilitating subsequent separation and removal. Adding flocculants before sludge dewatering can reduce sludge moisture content and improve filter pressing efficiency.

This causes the flocculants at the discharge end of the flocculant dosing device to be easily damp, prone to blockage, resulting in a decrease in the amount of medicine, causing the concentration of the medicine to decrease. The smooth and viscous properties of the damp flocculants increase the difficulty of equipment cleaning, not only increasing maintenance costs, but also affecting the accuracy of medicine dispensing due to changes in the weight of the damp flocculants.
