[0030] In this embodiment, the filter unit includes ceramic filter layer 7, activated carbon filter layer 8 and fiber filter layer 9 arranged in order from top to bottom. The ceramic filter layer 8 is made of foamed ceramic. The micro-porous structure of foamed ceramic is used to drive liquid through the pores of the filter layer by pressure difference, realizing the separation of solid and solution. It has the advantages of high efficiency, stability, corrosion resistance, long service life and environmental protection, and is suitable for various sewage treatment scenes. The activated carbon filter layer 8 can adsorb odor and color in sewage, improving the sewage purification effect. The surface of the fiber filter layer 9 provides a good biological attachment matrix, which is conducive to the attachment and growth of microorganisms, can degrade and decompose organic matter and pollutants in sewage, and further improve the purification effect of sewage; can realize hydraulic balance, make the water flow uniformly through the filter material layer, reduce the possibility of dead angle and leakage, and ensure high interception efficiency. The three filter layers cooperate to achieve efficient and high-quality filtration. The surface of the ceramic filter layer 7 is provided with a separation net 10. The separation net 10 can make the sheet-shaped particles or larger particles be blocked when they approach the ceramic filter layer 7. There is still space between the blocked sheet-shaped particles and the ceramic filter layer 7, so that sewage can enter and water is filtered. By cleaning the separation net 10 in time, the sheet-shaped particles or larger particles can be effectively prevented from blocking the micropores of the ceramic filter layer 7.
