Embodiment Construction

[0011] In order to make the objects, technical solutions and advantages of the present invention clearer, the following specific examples are given in conjunction with the appended figure 1 , the present invention will be described in further detail. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0012] exist figure 1 In the flow chart of the embodiment shown, a method for treating waste incineration slag includes the following steps: 1) Sorting: waste incineration slag is separated by crushing, magnetic separation, jigging separation, eddy current separation, and shaker separation. Sorting, vibration dehydration, and filter press dehydration processes to separate metal, sand, and mud; 2) Mixing: remix the sorted sand and mud to form a sand-mud mixture. The sand and mud mixture can be stored in a loose state for a long time, which can leave sufficient time for recyclin...

Abstract

The invention discloses a garbage incineration furnace slag treatment method. The garbage incineration furnace slag treatment method comprises the steps of 1) sorting and 2) mixing. The method breaksthrough the habit thought of direct separate treatment of sand and mud after sorting, mixes the sand and the mud again after sorting, solves the problem of difficult storage of the mud, is convenientto recycle the sand and the mud, and is mainly applied to the field of garbage incineration furnace slag treatment.

Description

technical field [0001] The invention relates to the technical field of waste incineration slag treatment, in particular to a treatment method for waste incineration slag. Background technique [0002] After the waste incineration slag is sorted, the products include metal, sand, and mud, which account for about 3%, 90%, and 7% of the mass respectively. Among them, the metal value is the highest, the sand is the second, and the mud is the lowest. Metal is easy to be fully recycled without occupying landfill land resources; due to the large output and the narrow application range of non-viscosity after washing and sorting, sand can only be used in a small part, such as brick making, most of which are landfilled, and still occupy a large amount of landfill Land resources; mud is mainly used for landfill because it cannot find a suitable use and has no economic benefits, thus occupying a large amount of landfill land resources. In the separate treatment process of mud, even aft...
