Landfill leachate treatment device and process based on enhanced Fenton oxidation method

Abstract

The invention provides a landfill leachate treatment device based on an enhanced Fenton oxidation method, wherein the landfill leachate treatment device comprises a device body that comprises a base; the top of the base is fixedly provided with a fixed seat, the fixed seat is respectively provided with a settling box, an aeration box and a filter box, the aeration box is arranged between the settling box and the filter box, and a feeding device is mounted on one side of the settling tank. When the device and the process are used, a motor of the feeding device rotates forwards to drive fan blades to rotate, a medicament in a feeding box is driven by wind power to enter a settling box, and the medicament is matched with a water inlet pipe to be uniformly matched with sewage, so that rapid settling is completed, and impurities are separated from water after settling. In the later period, through reverse rotation of a motor, power failure of an electromagnetic ring and cooperation of clamping teeth and tooth grooves, a movable pipeline rotates, and the inner wall of the filter plate is cleaned through rotation of the movable pipeline; meanwhile, through cooperation with the arc-shaped frame at the bottom, the sludge is discharged and finally discharged through the sewage outlet.

Description

technical field [0001] The invention relates to the field of landfill leachate treatment equipment, in particular to a landfill leachate treatment device and process based on an enhanced Fenton oxidation method. Background technique [0002] Landfill leachate is a water body with high concentration of organic matter and high salinity, which is very difficult to treat. As a mainstream organic matter removal process, Fenton has the pain points of low efficiency and high operating costs when facing landfill leachate. Sedimentation, aeration and filtration are required in the process of landfill leachate treatment. The existing sedimentation device cannot filter the impurities in the water while sedimentation is in use, and the filtration equipment cannot be cleaned after long-term filtration. It is easy to cause blockage of the equipment, and it is inconvenient to use. In addition, according to the different requirements for oxygen, the existing aeration equipment cannot adjust...

[0002] Landfill leachate is a water body with high concentration of organic matter and high salinity, which is very difficult to treat. As a mainstream organic matter removal process, Fenton has the pain points of low efficiency and high operating costs when facing landfill leachate. Sedimentation, aeration and filtration are required in the process of landfill leachate treatment. The existing sedimentation device cannot filter the impurities in the water while sedimentation is in use, and the filtration equipment cannot be cleaned after long-term filtration. It is easy to cause blockage of the equipment, and it is inconvenient to use. In addition, according to the different requirements for oxygen, the existing aeration equipment cannot adjust the aeration speed, so that the use of the device cannot be adjusted according to different situations, which is inconvenient to use. In addition, in In the engineering of activated carbon adsorption, impurities are often adhered to the activated carbon plate, so that the activated carbon plate cannot be fully adsorbed and used, and the function is single
