How to deal with construction waste, how to deal with environmental protection

With the improvement of people's living standards, there are more houses now. With the demolition, renovation, and various repairs of houses, various construction wastes have been produced. Do you know how to deal with these construction wastes?
 
Construction waste is the muck, spoil, spoil, and other waste generated during the construction and demolition of various buildings, structures, pipe networks, etc. by construction, construction units or individuals. With the development, more and more construction waste is generated by the construction of houses. Most construction waste is directly piled up in the open or landfilled. The land resources will be occupied and dust will cause serious pollution to the environment. Construction waste is piled for a long time. And landfills will penetrate into the soil and cause pollution to the soil and groundwater. The treatment of construction waste is also gradually improving. For example, waste building concrete, waste bricks and other materials can be used to produce coarse and fine aggregates for making wall panels, floor tiles and Base layer of highway pavement. However, these traditional treatment methods are not suitable for some areas, or they cannot solve the reuse of multiple recyclables. Therefore, there are more ways to explore how to deal with construction waste.

Construction waste is divided into four categories: construction waste, demolition waste, construction waste and decoration waste. The Interim Measures stipulate that engineering waste will be mainly used for comprehensive utilization and treatment methods such as engineering backfilling, greening backfilling, mountain landscaping, micro-topography or pit and mine restoration, and it is prohibited to enter temporary or fixed construction waste resource disposal facilities.
 
After demolition, a lot of demolition construction waste is often generated. Many people want to know how to deal with this waste, so how to deal with the demolition construction waste after demolition. Here are some suggestions.

1. The comprehensive treatment method of demolition construction waste. First, transport the demolition construction waste generated during the demolition of demolition, house decoration and road reconstruction to the treatment site, and then use manual methods to directly recycle the demolition construction waste. Materials such as metal materials, wood materials and plastic materials are sorted and classified, and directly supplied to the corresponding company for processing.
 
2. For the large pieces of waste concrete, waste bricks, marble and other materials in the demolition of construction waste, use a large hammer or crusher to crush to the size that the crusher can crush, generally less than 100 mm, and then crush it with a stone crusher To the stones and sand required for the demolition of the building, the above mixture is classified by a multi-layer grading screen into recycled materials such as coarse stones, fine stones, coarse sand, fine sand, and mud sand that meet the standards of the demolition building. The production water uses activated carbon reverse osmosis to purify domestic sewage and recycle it, which can save water and prevent the re-discharge of sewage from polluting the environment. If you find it troublesome, you can take him to the demolition construction waste disposal site yourself, but ordinary cities may not have such facilities.
 
3. Demolition construction waste backfilling is mainly used for site leveling, roadbeds, and depression filling. The demolition and construction waste used for site leveling and roadbeds should be broken and backfilled according to the requirements of use, and the demolition construction waste used for filling in depressions can be directly backfilled and used without being broken.
 
4. The temporary storage yard of demolition construction waste is mainly constructed in low-lying areas or valleys in the suburbs of cities and towns. After the conditions are mature, the demolition construction waste can be recycled or transferred to the landfill for disposal. The temporary storage site for demolition construction waste should be located in an area with convenient transportation, close to the source of demolition construction waste, and will not be planned for use in the near future, and the storage capacity will meet the requirements for temporary storage; it is prohibited to set up in the groundwater centralized water supply source and replenishment area , Activities collapsed zone, scenic sightseeing area and cultural relic area.
 
5. Demolition of construction waste landfills can be centrally set up at the city and county level. Demolition of construction waste landfills should be selected in natural low-lying valleys (cols), quarry waste pits and other areas with convenient transportation, reasonable transportation distance, low land use value, and poor groundwater. The landfill storage capacity shall ensure the landfill volume of the damaged demolition construction waste and the demolition construction waste reconstructed after the disaster in the service area.

Construction waste mobile crushing station

In addition, it is necessary to make full use of the recyclables in construction waste. For example, steel bars can be recycled into the furnace, wood can be crushed and reprocessed in a furniture factory, and large pieces of concrete can be crushed by a construction waste shredder and become sand and gravel. The buildings used can also be processed into various floor tiles, net red bricks, water-absorbing bricks, etc., for urban construction and beautification, so that construction waste can not only be recycled and used, but also make money and generate income.
