Problems solved by technology

Among them, in the process of using the activated sludge method to treat the leachate, it is necessary to carry out secondary precipitation on the landfill leachate, then add activated sludge powder and use the aeration tank for aeration treatment, and then use the concentration tank and drying equipment to treat the sludge. The overall process is relatively complicated, and the drying effect on sludge is average, and the sludge cannot be effectively treated

Embodiment Construction

[0038] see Figure 1~5 , the present invention provides a landfill leachate treatment equipment, comprising:

[0039] Concentration tank 1 is used to receive landfill leachate after secondary precipitation. Secondary precipitation is a pretreatment process for landfill leachate, which includes physical precipitation and chemical precipitation, so that turbidity, CODcr, and ammonia nitrogen can be better The removal effect lays a good foundation for subsequent treatment. In addition, a feed port 11 is provided above the concentration tank 1 for receiving landfill leachate and activated sludge powder, and an aeration system can also be set in the concentration tank 1 And the rotation is provided with a scraper 13, and the scraper 13 is driven and rotated by an external motor device. The motor device here includes a motor and a gearbox. In the early stage of the activated sludge powder input, the external motor device is used to drive the scraper 13 to perform conventional rotati...

Abstract

The invention discloses landfill leachate treatment equipment, and relates to the technical field of landfill leachate treatment. The landfill leachate treatment equipment comprises a concentration tank used for receiving landfill leachate subjected to secondary precipitation; a feeding mechanism of which the feeding end is communicated with the sludge discharging end of the concentration tank; a mixing and drying mechanism which has a feeding end communicated with the discharging end of the feeding mechanism, and can further dry sludge; and at least one guiding drying bin of which the feeding end is communicated with the discharging end of the mixing and drying mechanism through a discharging bin, the interior of the discharging bin being further communicated with a high-pressure pumping machine which can pump high-temperature and high-pressure gas into the guiding drying bin.

Description

technical field [0001] The invention relates to the technical field of landfill leachate treatment, in particular to equipment for landfill leachate treatment. Background technique [0002] Landfill leachate is mainly secondary pollutants produced by garbage after sanitary landfill. Generally speaking, the treatment of landfill leachate includes physical and chemical methods and biological methods; among them, the cost of physical and chemical methods is relatively high, so for The treatment method of landfill leachate mainly adopts biological method. Biological methods include aerobic biological treatment, anaerobic biological treatment, etc. Among them, in the process of using the activated sludge method to treat the leachate, it is necessary to carry out secondary precipitation on the landfill leachate, then add activated sludge powder and use the aeration tank for aeration treatment, and then use the concentration tank and drying equipment to treat the sludge. Treatmen...
