Efficient filtrate collection and treatment system for underground landfill

According to the technical scheme, the efficient filtrate collecting and treating system of the underground landfill comprises a filtrate collecting and treating pond, three partition plates are arranged in the filtrate collecting and treating pond, and the partition plates divide the filtrate collecting and treating pond into a settling pond, a fungus treating pond, a plant treating pond and an application pond. An overflow hole is formed in each partition plate, and a screen is arranged in each overflow hole; wherein filtrate collecting pipes are arranged above the sedimentation tank at intervals, a filter screen is horizontally arranged in the sedimentation tank, a stop valve is arranged on each filtrate collecting pipe, and a flow slowing device is further arranged on each filtrate collecting pipe; the device has the beneficial effects of high filtrate efficiency, low energy consumption, good treatment effect and recyclability, and prevents the filtrate from being directly discharged to pollute the surrou
