Embodiment 1

[0021] Embodiment 1 is basically as attached figure 1 Shown: a treatment device for concentrated landfill leachate, including a box body 1, an aerator 6 and a feeding box 15, the box body 1 is provided with a drum 2 with one end open, and the open end of the drum 2 faces downward, And it is rotatably connected with the box body 1, the bottom of the box body 1 is provided with an installation groove, the first motor is fixedly connected in the installation groove, the output shaft of the first motor is fixedly connected with the driving gear 5, and the bottom of the drum 2 is fixedly sleeved. There is a toothed ring 16, and the driving gear 5 meshes with the toothed ring 16; the drum 2 is surrounded by a hollow side plate 3, and the side plate 3 is spirally wound on the outer wall of the drum 2, and the drum 2 communicates with the side plate 3, The end of the side plate 3 away from the drum 2 is evenly distributed with working holes 4, the bottom of the box body 1 is fixedly c...

Embodiment 2

[0023] Example 2 and figure 2 As shown, the difference from Embodiment 1 is that the driven gear 5 is engaged with a driven gear 17 on the side away from the drum 2, the driven gear 17 is fixedly connected with a worm 18, the worm 18 is meshed with a worm gear 19, and the worm gear 19 is fixedly connected with a Screw 21, the two ends of the screw 21 are rotatably connected with the side wall of the box 1, the screw 21 is threaded with a trapezoidal slag scraper 20, the side wall of the box 1 is provided with a horizontal chute, and the slag scraper 20 is slidably connected in the chute

[0024] Taking Example 2 as an example, when in use, put the leachate into the box body 1, put the heavy metal scavenger diluted with water into the feeding box 15, turn on the first motor, and the controller controls the first motor intermittently. Rotate, the first motor drives the driving gear 5 to rotate forward and backward intermittently, because the driving gear 5 meshes with the gear...

Abstract

The invention discloses a landfill leachate concentrated solution treatment device, and belongs to the field of environmental protection equipment. The device comprises a box body, an aeration machine and a feeding box, a rotating cylinder with an opening in one end is arranged in the box body, the rotating cylinder is rotationally connected with a first driver for driving the rotating cylinder to rotate, a hollow side plate is arranged on the rotating cylinder in a surrounding mode, and the side plate is spirally arranged on the outer wall of the rotating cylinder in a winding mode; the rotating cylinder is communicated with the side plate, and one end, away from the rotating cylinder, of the side plate is evenly provided with operation holes. The bottom of the box body is provided with a transition box with an opening in one end, the opening of the rotating cylinder is rotationally connected with a connecting cylinder, the end, away from the rotating cylinder, of the connecting cylinder is fixedly connected with the transition box, connecting openings are formed in the two opposite sides of the connecting cylinder, and a rotating disc is arranged at the bottom of the connecting cylinder. The rotating disc is connected with a second driver for driving the rotating disc to rotate, a fixing shaft is arranged on the rotating disc, a blocking piece is connected to the fixing shaft, one connecting port is communicated with the aeration machine, and the other connecting port is communicated with the feeding box. According to the device in the scheme, the leachate and the heavy metal capturing agent can be fully mixed.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to a treatment device for concentrated landfill leachate. Background technique [0002] Landfill leachate refers to the moisture contained in the garbage itself in the landfill, the rain and snow water and other moisture entering the landfill, deducting the saturated water holding capacity of the garbage and the covering soil, and passing through the garbage layer and the covering soil. A high concentration of organic wastewater. [0003] Garbage disposal methods include sanitary landfill, incineration, composting, etc., but no matter which process will produce landfill leachate. At present, landfill leachate treatment technology is still a worldwide problem, especially the high-concentration landfill leachate produced after reverse osmosis treatment is more difficult to deal with. Due to the dissolution of CO2 produced by garbage degradation, the landfill leachat...
