Description

A continuous sand filter for sewage treatment

Technical Field

The utility model relates to the technical field related to quicksand filters, in particular to a continuous quicksand filter for sewage treatment.

Background Art

Quicksand filter is the most economical and effective solution for removing suspended solids and other impurities in water treatment and sewage purification. It can effectively remove impurities such as suspended particles and colloids in raw water (or wastewater). In the water treatment process, its working principle is to transport raw water into the sand bed so that the water flows from bottom to top through the sand bed, and the flocculants are adsorbed by the sand bed to achieve the purpose of raw water purification. It has the advantages of high filtration efficiency, low energy consumption, and simple operation.

After long-term use, the existing quicksand filter will have a lot of impurities accumulated inside the quicksand, and will continue to accumulate in the filter material layer. Gradually, the pores of the filter layer will be blocked by suspended matter, causing it to lose its filtering ability. It is usually necessary to take the quicksand out of the filter and wash the quicksand. This process is more cumbersome, increases the workload of the staff, and affects work efficiency.
