Heavy metal ion precipitation and collection tank for landfill leachate

Abstract

The invention discloses a heavy metal ion precipitation and collection tank for landfill leachate, which improves the treatment efficiency of landfill leachate treatment and comprises a tank body, a stirring frame is fixedly mounted on one side of the upper part of the inner side of the tank body, and a stirring motor is fixedly mounted on the stirring frame and in the middle of the tank body. The output end of the stirring motor is connected with a stirring rod extending below the tank body, a plurality of groups of stirring impellers are arranged on the stirring rod, a reciprocating stirring mechanism is further mounted at the bottom of the tank body, the reciprocating stirring mechanism comprises a driving part and a stirring assembly, the stirring assembly is mounted on the driving part, a screening and washing box is installed on the other side of the tank body, a swing structure is arranged between the screening and washing box and the stirring rod, and a jacking mechanism is further installed at the lower end of the screening and washing box. The energy is saved, the purification effect is improved, and the purification efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of landfill leachate treatment, in particular to a heavy metal ion precipitation collection pond for landfill leachate. Background technique [0002] The landfill leachate mainly comes from the high-concentration harmful waste liquid formed by the waste itself containing water or the water generated during the degradation process, plus precipitation, groundwater, and surface water during the landfill process. It has complex pollutant components, large fluctuations in water quality, and organic pollution. It has the characteristics of high substance concentration, high ammonia nitrogen concentration, deep color, strong odor, high heavy metal ion concentration and salt content, and strong toxicity. If it cannot be properly disposed of, it will cause serious pollution to the water environment, atmospheric environment and soil environment, and endanger human health. The existing landfill leachate treatment proc...

AI Technical Summary

Problems solved by technology

[0003] The existing landfill leachate treatment is to landfill the garbage first, and then collect the harmful waste liquid for treatment. The area of ​​the treatment pool is relatively large, and starch needs to be put in when cleaning heavy metal ions, and the starch is placed on the edge of the pool, and the middle position is difficult. Quickly absorb starch, which reduces the processing efficiency
