Problems solved by technology

[0003] Engineering slag is mainly composed of mud, scattered mortar and concrete fragments, bricks and stones produced by chiseling, scrap metal, bamboo wood, waste generated in the process of building decoration, various packaging materials and other wastes, etc. , the proportion of soil is about 60%. Since the muck contains a lot of alkaline concrete, the pH value is as high as 12-13, which belongs to strong alkali and seriously pollutes the environment. It should be treated when it is reused; while the traditional The muck disposal method is landfill, stacking, etc., which not only wastes resources, but also pollutes the environment and causes secondary pollution. Therefore, a harmless muck disposal system is urgently needed

Abstract

The invention provides a harmless muck treatment system. The harmless muck treatment system comprises a crusher, a stirring device, a repairing box, a separation pool and a filter press, wherein a feeding opening of the crusher is connected with a raw material conveying device, a discharging opening of the crusher is connected with a second conveying device, and the second conveying device is connected with a hopper; a feeding opening of the stirring device is connected with the hopper, the stirring device can be a rotary tank stirrer, the repairing box is also connected to the feeding opening of the stirring device, the discharging opening of the stirring device is connected with a feeding opening of the separation pool, a feeding opening of the filter press is connected with the discharging opening of the separation pool through a filter pressing pump, and a discharging opening of the filter press is connected with a discharging opening of the separation pool; and a discharging opening of the filter press is connected with the second conveying device. According to the harmless muck treatment system, by arranging the repairing box and the stirring device, waste soil and repairing liquid are mixed more evenly, the repairing effect is more obvious, the treated waste soil can be free of pollution residues, and the purpose of innocent treatment is achieved.

Description

technical field [0001] The invention relates to the field of construction dregs treatment, in particular to a harmless dregs treatment system. Background technique [0002] With the continuous expansion of the urbanization process, the discharge of engineering muck has increased year by year. Most of the dregs are mainly stacked in the open air. After long-term exposure to the sun and rain, harmful substances in the garbage enter the soil through alkaline substances, resulting in A series of physical, chemical and biological reactions, or absorbed by plant roots or synthesized by microorganisms, resulting in soil pollution. During the stacking process of muck, mixed domestic garbage, under the action of temperature, moisture, etc., some organic substances decompose and produce harmful gases; at the same time, bacteria and dust in the garbage are scattered, causing air pollution; a small amount of combustible light substances Toxic substances will be produced, causing air po...
