[0002] With economic development and increased emphasis on water resource protection, regulatory authorities and various industries have gradually raised water treatment standards, especially the requirements for the removal of nitrogen pollutants from wastewater.

[0003] Currently, the main method for solving filter clogging is backwashing. However, ordinary water washing has low intensity, and although air washing can effectively remove caking and destroy the anaerobic environment of the filter bed, water flow and air bubbles can easily pass through the gaps with low resistance, which cannot completely break up the caking, and backwashing is often incomplete.
