Description

Technical Field

[0001] The invention relates to the field of garbage wastewater treatment equipment, and in particular to a device for resource treatment of garbage leachate and sewage. Background Art

[0002] In the past, domestic waste in rural areas was discarded and piled up at random, causing great pollution to the environment. However, with the continuous development of society and the continuous improvement of living standards, most villages have set up medium-to-large centralized garbage bins or garbage pools, and townships organize regular and fixed-point recycling and unified treatment, which has greatly improved the ecological environment.

[0003] However, the villages are not concentrated together, and the courtyards in each village are relatively scattered. Generally, each village will have 2-5 garbage bins or garbage pools. The distribution of these garbage bins varies, and the garbage bins cannot be cleaned in time every day. They are generally cleaned and recycled on a weekly or monthly basis.

[0004] There are various types of garbage, especially a large amount of kitchen waste. During the stacking process, filtrate and sewage will seep out due to material fermentation, rainwater erosion and air humidity. The filtrate and wastewater that seep out are high-concentration organic wastewater with complex water quality and great environmental hazards. It is easy to cause secondary pollution, so the existing centralized garbage bins and garbage pools need to be improved. Summary of the invention

[0005] In order to make up for the above-mentioned deficiencies, the present invention provides a device for resource treatment of landfill leachate and sewage.

[0009] For further optimization, the barrel cover is in the shape of an inverted funnel and is a double-layer barrel cover. The inner layer of the barrel cover is provided with evenly distributed leakage holes. A diverter cone is also fixed to the upper part of the inner layer of the barrel cover. The diverter cone is opposite to the inlet of the barrel cover. The inlet is connected to the filter area of ​​the filter barrel through the interlayer and the leakage holes between the double-layer barrel cover.

[0010] For further optimization, a pull-out drawer is provided in the middle of the box seat, a plurality of third through holes are provided on the lower wall of the drawer, the first filter layer is located in the drawer, the lower wall of the box seat is funnel-shaped, and the outlet is provided in the middle position of the lower wall of the box seat.

[0017] The beneficial effects of the present invention are:

[0018] This device can replace the existing medium and large garbage bins or garbage pools in rural areas and can be used for a long time after installation. The garbage bin and the bin seat adopt a separate design, which is convenient for the garbage truck to lift the garbage bin for garbage recycling and cleaning. The first filter layer filters and the second filter layer filters the garbage leachate. The purified leachate infiltrates into the soil from the infiltration pipe to avoid pollution caused by the garbage leachate.

[0019] The leachate generated in the garbage bin first enters the bin seat, is filtered through the first filter layer, and then enters the filter barrel to be filtered through the second filter layer. Finally, the treated leachate seeps into the soil from the infiltration pipe in the buffer zone. The first filter layer includes an anthracite filter layer and a fruit shell filter layer, which can absorb odors and oil for coarse filtration. The second filter layer performs fine filtration. The first filter layer is set in the drawer of the bin seat to facilitate regular maintenance and replacement.

[0020] A baffle is provided at the bottom of the trash bin, which can be lifted by a pressure rod. The baffle can temporarily cover the through holes at the bottom of the bin, making it convenient for the first filter layer to be replaced and for the garbage truck to lift the trash bin for recycling and cleaning, thereby preventing the garbage filtrate from dripping everywhere.

[0021] The filter barrel is equipped with a barrel cover to minimize the escape of odor from the garbage leachate. The barrel cover adopts a double-layer design, and the inner layer of the barrel cover is in the shape of an inverted funnel, which cooperates with the diversion cone on the top to play a diversion role, avoid concentrated use of the middle filter material, use the filter material evenly, and extend the service life.

[0022] The filter barrel is divided into a filtration area and a buffer zone. When a large amount of treated leachate is washed by rainwater, it can be temporarily stored in the buffer zone. The buffer zone is equipped with an infiltration pipe buried in the soil to lead the purified and filtered leachate out for a certain distance and then infiltrate into the soil, avoiding direct infiltration from the filter barrel into the soil and causing muddy sedimentation in the surrounding soil.
