1. Comprehensive treatment method of construction waste: firstly, the construction waste generated in the process of building demolition, house decoration and road reconstruction is transported to the treatment site by car, and then the materials that can be directly recycled in the construction waste, such as metal materials, wood materials, plastic materials, etc., are manually sorted and classified and directly supplied to the corresponding companies for treatment.
2. Crush large pieces of waste concrete, waste bricks, marble and other materials in construction waste with a sledgehammer or crusher to the size that the crusher can crush, which is generally less than 100 mm, and then crush them into stones and sand needed for construction with a stone crusher, and then the mixture is graded into recycled materials such as coarse stones, fine stones, coarse sand, fine sand and mud sand that meet the building standards through multi-layer grading screening. Using activated carbon reverse osmosis to purify and recycle domestic sewage can not only save water, but also prevent sewage from being discharged again and polluting the environment. If it's too much trouble, you can drag him to the construction waste disposal site yourself, but there may be no such facilities in ordinary cities.
: 1. Construction waste backfilling is mainly used for site leveling, road subgrade and depression filling. Construction waste used for site leveling and road subgrade should be crushed and backfilled according to the use requirements, and construction waste used for filling depressions can be backfilled directly without crushing.
2. The temporary storage yard of construction waste is mainly built in low-lying areas or valleys in the suburbs of cities and towns. When conditions are ripe, construction waste can be recycled or transported to landfill for disposal. The temporary storage yard of construction waste should be located in an area with convenient transportation, close to the source of construction waste, and it is not planned to be used in the near future, and the storage capacity can meet the requirements of temporary storage; It is forbidden to set up in centralized groundwater recharge sources and recharge areas, active subsidence areas, scenic spots and cultural relics and historic sites.
3. Construction waste landfills can be set up in cities and counties. Construction waste landfill sites should be selected in natural low-lying valleys (depressions), quarry pits and other areas with convenient transportation, reasonable transportation distance, low land use value and poor groundwater; The landfill capacity shall ensure the quantity of damaged construction waste and post-disaster reconstruction construction waste in the service area.
