Construction waste treatment methods:
1, comprehensive construction waste treatment methods, first of all, the demolition of buildings, house renovation and reconstruction of roads in the construction waste generated by the car to the treatment site, and then, by artificial means of the construction waste can be directly recycled materials, such as metal materials, wood-based materials and plastic materials sorting classification, and directly supplied to the corresponding company for processing.
2. For the large waste concrete, waste bricks, marble and other materials in the construction waste, use the large broken hammer or crusher to crush them to the size that the crusher can crush, which is generally less than 100 millimeters, and then crush them to the stone and sand required for the construction with the stone crusher, and then use the above mixture with the multi-layer grading sieve to grade into the coarse stone, fine stone, coarse sand, fine sand, mud and sand, and other recycled materials in line with the construction standards. Then the above mixture is graded into coarse stone, fine stone, coarse sand, fine sand, and recycled materials such as mud and sand by multi-layer grading screen. The water used for production is purified by reverse osmosis with activated carbon and recycled, which can save water and prevent the re-emission of sewage from polluting the environment. If it is too much trouble, you can pull him to the construction waste disposal site yourself, but the average city may not have this kind of facility ah.
:1, construction waste backfill utilization is mainly used for site leveling, road beds, depression filling. For site leveling, roadbed construction waste should be crushed according to the requirements of the use of backfill utilization, used to fill the depression of construction waste can not be crushed directly backfill utilization.
2, construction waste temporary storage yard mainly use the town outskirts of low-lying land or valley and other places to build, conditions are ripe, can be used for resource utilization of construction waste or transfer to the landfill disposal. Construction waste temporary storage dumps should be located in convenient transportation, closer to the source of construction waste, will not be planned for use in the near future, the reservoir capacity to meet the requirements of temporary storage dumps; prohibited from being set up in the groundwater centralized water supply sources and recharge areas, activities of the collapsed zone, scenic spots and cultural relics area.
3, construction waste landfill can be set up centrally for the city, county units. Construction waste landfill should be selected in the natural low-lying terrain of the valley (col), quarry waste pit and other convenient transportation, transportation distance is reasonable, low value of land use, groundwater-poor areas; landfill capacity should be guaranteed to serve the region of the destruction of construction waste and post-disaster reconstruction of construction waste landfill volume.
