Description

Technical Field

[0001] The utility model relates to the technical field of chemistry, in particular to a reverse osmosis filtering device for garbage leachate. Background Art

[0002] Garbage leachate refers to the water contained in the garbage itself in the landfill, the rain and snow water entering the landfill and other water, minus the saturated water holding capacity of the garbage and the covering layer. The Chinese utility model patent, authorization announcement number "CN220579010U", discloses a reverse osmosis treatment device for garbage leachate, including a connecting plate, and a support block is connected to one side of the upper end of the connecting plate. The reverse osmosis treatment device for garbage leachate can be conveniently filtered for solid impurities in the leachate through the mutual cooperation of the connecting cylinder, motor, mounting plate, filter cylinder, filter screen, feed pipe, opening and feed block. Through the high rotation of the national travel, the liquid in the filter cylinder is directly thrown out to the inside of the connecting cylinder, which is convenient for filtering the solid impurities in the leachate, increasing the leachate treatment effect, and can be convenient for directly transporting the filtered leachate to the first treatment cylinder and the second treatment cylinder. The leachate can be reverse osmosis treated for multiple times to improve the leachate treatment effect.

[0003] The above technical solution allows the leachate to enter the filter cartridge through a feed pipe, and a motor drives the mounting plate and the filter cartridge to rotate, so that solid impurities in the leachate can be filtered, and the solid impurities remain in the filter cartridge. The leachate flows to the connecting cartridge, and the reverse osmosis membrane in the first treatment cartridge treats the leachate, and the treated leachate is discharged through a discharge pipe. However, the above technical solution still has certain defects. For example, the above equipment drives the mounting plate and the filter cartridge to rotate through a motor, so that solid impurities in the leachate can be filtered, but the filter cartridge needs to be disassembled for long-term use to clean and maintain the filter screen, and the staff needs to use special tools to disassemble it, which greatly increases the workload of the staff and reduces the efficiency of disassembly of the filter screen.
