Embodiment Construction
[0018] The present invention will be further described below in conjunction with the accompanying drawings.
[0019] The metallurgical slag stockpile treatment method comprises the following steps:
[0020] a. Build the cast-in-place foundation 2 and the retaining wall based on the cast-in-place foundation 2 at the recycling site;
[0021] b. Fill the metallurgical slag 14 in layers as filler and compact it in the area surrounded by the retaining wall, and a reinforcing mesh 13 is arranged between each layer of metallurgical slag 14;
[0022] c. The slope body 1 is formed by the metallurgical slag 14 and the reinforced mesh 13, and the slope surface 15 of the slope body 1 is provided with a gravel filter layer 12;
[0023] d. A greening layer 11 is provided on the surface of the crushed stone filter layer 12 .
[0024] With the intensification of energy conservation and emission reduction, pollutant treatment has become an important and arduous task at present. In order to m...

The invention relates to the field of metallurgical slag storage yard governing methods, in particular to a metallurgical slag storage yard processing method. In order to solve the technical problems, the metallurgical slag storage yard processing method which can effectively process steel metallurgical slag so as to reduce secondary pollution of the slag is provided. The metallurgical slag storage yard processing method includes the steps of firstly, building a cast-in-place foundation and a barricade with the cast-in-place foundation as the foundation in a recycle place; secondly, filling the area defined by the barricade with the metallurgical slag as packing in a layered mode, compacting the metallurgical slag in the area defined by the barricade, wherein a reinforced net is arranged between every two adjacent layers of metallurgical slag; thirdly, forming a slope through the metallurgical slag and the reinforced nets, wherein a broken stone inverted filter layer is arranged on the slope surface of the slope; fourthly, arranging a greening layer on the surface of the broken stone inverted filter layer. The method is particularly suitable for the governance in metallurgical slag storage yards in steel plants.
Description
technical field [0001] The invention relates to the field of treatment methods for metallurgical waste slag storage yards, in particular to a treatment method for metallurgical slag storage yards. Background technique [0002] Iron and steel smelting will inevitably produce a large amount of waste slag dumping. With the improvement of environmental protection requirements, slag yard treatment is inevitable. For abandoned metallurgical storage yards, it is very easy to cause environmental pollution, such as dust, water pollution, etc., which have a greater impact on the surrounding environment and seriously affect the local environmental development. At the same time, for the continuous and stable production of steel mills, it is necessary to solve the contradiction between waste disposal and environmental protection, so it is necessary to treat the slope of the slag yard. Contents of the invention [0003] The technical problem to be solved by the present invention is to ...
