Description

Technical Field

[0001] The invention relates to the technical field of landfill leachate treatment, in particular to a biological treatment device for landfill leachate. Background Art

[0002] Leachate refers to a high-concentration organic wastewater formed by the moisture contained in the garbage itself in the landfill, rainwater, snow and other moisture entering the landfill, minus the saturated water holding capacity of the garbage and covering soil layers, and passing through the garbage layer and covering soil layer. Existing landfills need to treat the leachate before landfilling to prevent the leachate in the garbage from infiltrating into the soil and causing land and water pollution.

[0003] After searching, the Chinese patent application No. 202222357926.9 discloses a landfill leachate treatment device, including a liquid collecting box, the top of which is fixedly connected to a leachate extrusion box by bolts, a feed inlet is provided on the top of the leachate extrusion box, and a loading plate is rotatably connected to the top of the leachate extrusion box at a position on one side close to the feed inlet by a hinge, a fixed platform is fixedly connected to the top of the leachate extrusion box at a position on the other side close to the feed inlet by bolts, and a first cylinder is fixedly connected to the top of the fixed platform by bolts; Although the above patent is convenient for squeezing out the wastewater in the garbage, it still has the following shortcomings during use: 1. During long-term use, when the garbage is placed in the filter rack for wastewater extrusion, the first filter hole and the second filter hole are easily blocked due to the accumulation of impurities, making it difficult to fully squeeze out the wastewater in the garbage. This not only reduces the wastewater treatment efficiency, but also may cause the residual wastewater in the landfill to infiltrate into the soil, causing environmental pollution; 2. When wastewater is extracted through a liquid pump, solid impurities may still remain in the wastewater due to incomplete filtration. After these impurities enter the liquid pump, they may easily cause internal wear or blockage of the pump body, thereby affecting the normal operation of the equipment and reducing the efficiency of wastewater extraction.

[0030] During operation (or use): During operation, first start the driving motor 146 to drive the rotating rod 140 to rotate. When the rotating rod 140 rotates, the vibration block 141 squeezes the filter plate 111 to make the filter plate 111 slide upward; when the vibration block 141 is away from the filter plate 111, the second spring 143 and the third spring 145 drive the filter plate 111 to reset, and the garbage is poured into the filter plate 111 in the separation bucket 110. The water inside the garbage is preliminarily filtered through the holes on the filter plate 111. The filtered water enters the separation bucket 110. The filter plate 111 is tilted and continuously shakes, so that the garbage enters the separation ring 124. When the separation ring 124 When the garbage in the garbage reaches a certain height, stop pouring the garbage, start the second driving screw 133 to drive the slider 123 to move, so that the separation ring 124 moves to the top of the squeezing plate 161, start the cylinder 160 to push the squeezing plate 161 to move downward, enter the separation ring 124 and squeeze the garbage, so that the liquid in the garbage is squeezed out through the water outlet trough 132 and enters the filter box 120 through the filter tank 121 to achieve centralized treatment of wastewater. When the water in the garbage is completely squeezed out, start the first driving screw 112 and the second driving screw 133 at the same time, the first driving screw 112 drives the adjustment plate 103 to move, and the moving wheel 163 slides in the slide trough 102 to raise the adjustment plate 103 is convenient to move, the second driving screw 133 drives the separation ring 124 to move synchronously, when the adjusting plate 103 moves, the gear 106 rotates under the action of the rack 107, and drives the cleaning pad 109 to rotate along the outer wall of the separation ring 124 through the connecting frame 108 to clean the blocked impurities in the water tank 132, when the separation ring 124 moves, the slider 123 drives the deflection plate 125 to move, the deflection plate 125 pulls the scraper 126 to slide on the filter box 120, and cleans the blocked impurities in the filter tank 121, when the separation ring 124 moves away from the top of the filter box 120, the processed garbage falls to one side of the processing bucket 100 under the action of gravity, and the scraper 126 6.

When the guide blocks 131 on both sides of the scraper 126 contact the triangular block 129, the triangular block 129 is squeezed into the reset groove 128; when the guide block 131 is away from the triangular block 129, the first spring 130 drives the triangular block 129 to reset. When the separation ring 124 is reset, the guide block 131 slides along the triangular block 129 into the inclined part, and the deflection plate 125 deflects to avoid affecting the movement of the scraper 126. When the guide groove 127 moves to the vertical part, the scraper 126 falls to the horizontal part at the bottom through the vertical part under the action of gravity, preventing the impurities from being scraped to the side of the scraper 126 away from the garbage storage, thereby improving the use effect; At the same time, during use, when it is necessary to discharge the waste water inside the separation bucket 110 and the treatment bucket 100, the solenoid valve 152 is opened to allow the first water outlet pipe 150 and the second water outlet pipe 151 to start draining. While the drive motor 146 rotates, the first pulley group 155 drives the first anti-blocking rod 153 to rotate, and the first scraper bar 154 rotates inside the first anti-blocking rod 153, thereby preventing impurities from clogging the first water outlet pipe 150. The second anti-blocking rod 156 is driven to rotate by the second pulley group 157, so that the second scraper bar 158 rotates inside the second water outlet pipe 151, thereby preventing impurities from clogging the second water outlet pipe 151, which is beneficial to improving the smoothness of sewage discharge and is more convenient to use.
