Description

Technical Field

[0001] The utility model relates to the technical field of leachate treatment, in particular to a leachate treatment device for a county garbage incineration plant. Background Art

[0002] Leachate refers to a high-concentration organic wastewater that is a mixture of various substances such as substances in garbage and water on the site in a landfill. Direct discharge of this wastewater will cause serious damage to the environment. Therefore, it needs to be effectively filtered, neutralized and biologically reacted before it can finally meet the emission standards before being discharged.

[0003] The existing county-level waste incineration plant leachate treatment device is difficult to effectively separate the colloidal wastewater with high viscosity and relatively fragmented solids. In addition, the wastewater filtered by the traditional filtration method still contains a large number of large particles, which causes unnecessary trouble for subsequent treatment.

[0004] The existing patent (Announcement No.: CN214218359U) is a domestic waste leachate treatment device for a waste incineration plant. This utility model solves the problem that the traditional filtering solid-liquid separation method cannot effectively separate the relatively viscous colloidal or waste liquid mixture mixed with small particles of soil and garbage during the traditional leachate treatment through the setting of a dehydration component. The mixed particles in the filtered leachate are smaller, which reduces the possibility of blockage in the subsequent treatment process and makes the subsequent treatment more convenient.

[0005] In view of the above problems, existing patents have provided solutions, but in actual use, the treatment of landfill leachate is relatively simple, so that the treated landfill leachate still has certain pollution, causing damage to the environment.

[0006] Therefore, a leachate treatment device for county waste incineration plants is proposed. Utility Model Content
