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

Construction waste refers to the solid waste generated when a building is newly built, reconstructed, expanded or demolished.

At present, most of China's construction waste is stacked and landfilled, but we ignore that this often leaves a great hidden danger. The long-term accumulation of construction waste not only occupies land, but also causes serious pollution to the environment, surface water and groundwater, and directly or indirectly affects air quality.

Therefore, if we can't reuse construction waste, it will have a great negative impact on our living environment. So how should construction waste be disposed of?

When dealing with construction waste, two treatment methods are often chosen:

1.Resource utilization of the factory.

This treatment method is to construct construction waste treatment in a closed workshop.

The production line adopts professional fixed crushing and screening equipment to treat and reuse construction waste, which can reduce pollution, low emissions, and produce aggregates of different specifications and standards. There are two kinds of equipment commonly used, crushing equipment and screening equipment, and the crushing equipment is divided into coarse crushing, medium crushing and fine crushing. It is mainly used to reduce the particles of construction waste, and is often used to make stones or sand making.

Screening equipment includes pre-screening and inspection screening, which is mainly used to separate hazardous materials and divide the discharged finished product into different particle sizes for different recycling processes.

Secondary crusher-cone crusher <>

Fine crushing - sand making machine.

2.In-situ renewable resource utilization.

This treatment method is directly processed at the construction waste site. Mobile crushing plants are often used for treatment. A variety of different equipment can be combined with each other as needed, and can be moved close to the processing point at will, reducing transportation costs and avoiding secondary pollution.

If the construction waste can be treated well, not only can the environmental benefits be obtained, but also good economic benefits can be obtained.

Its recycled aggregates are widely used in road engineering, gardens, river slope protection and other fields.

If you plan to invest in construction waste treatment, you can consult specifically.

Construction waste disposal method:

Comprehensive treatment method of construction waste, first of all, the demolition of buildings, house decoration and renovation of the road in the construction waste generated by the vehicle to the treatment site, and then, the construction waste in the construction waste can be directly recycled by artificial means, such as metal materials, wood materials and plastic materials sorting and classifying, directly supplied to the corresponding company for treatment. For the large pieces of waste concrete, waste bricks, marble and other substances in the construction waste, the large hammer or crusher is used to crush to the size that the crusher can crush, generally less than 100 mm, and then the stone crusher is used to crush to the stones and sand required for construction, and then the above-mentioned mixture is graded into coarse stones, fine stones, coarse sand, fine sand, and recycled materials such as mud and sand that meet the construction standards with multi-layer grading screens. Activated carbon reverse osmosis is used to purify domestic sewage and recycle the production water, which can not only save water but also prevent the re-discharge of sewage from polluting the environment.

If you are too troublesome, you can pull him to the construction waste disposal site by yourself, but the average city may not have such facilities.

When developers build houses and buyers decorate houses, they will create a lot of construction waste, some people will transport these garbage to the garbage station, and some people will put the garbage directly in the garbage point of the community, but the construction waste should really be placed in how to deal with it, whether it can be used These problems are not well understood by many people. The following little brother hides a detailed description of the problem of construction waste.

First, how to deal with construction waste.

The construction waste on the construction site can be transported to the geographical location designated by the local department, and then the relevant personnel will classify and sort the construction waste, and send the resources to the station.

Second, how to deal with construction waste.

1. You can consult the property company of the community to see if there is a place for placing construction waste in the community, if there is, then after the construction waste is generated, it can be transported directly to the designated point.

2. You can consult the staff of the neighborhood committee, contact the local sanitation workers, choose the right time to clean up the garbage, and then directly pay the transportation fee.

3. Find a muck truck by yourself, and let the muck truck transport the construction waste to the local construction waste treatment station after dark.

Third, whether construction waste can be **.

This depends on the sorting of waste items in construction waste, such as waste building concrete, bricks, steel bars, steel, glass, and plastics.

Fourth, the difference between construction waste disposal and other waste disposal.

1. Construction waste must first be declared to the local Urban Environmental Sanitation Administration, and then develop a first-class point.

2. It must be transported to the designated location by a special garbage truck, and it must be transported within the specified time.

Fifth, what is the current situation of construction waste disposal in China.

1. The rate of construction waste is not very high, and construction waste is often mixed with some other waste.

2. China's construction waste treatment technology is relatively backward, many cities will not decompose, but will directly take landfill treatment, this way is particularly serious environmental pollution.

More and more people are moving closer to the city, so more houses are coming to the city. And the construction waste produced is also increasing. So, do you know what Zheng Jin should do with this garbage?

In this process of decoration, where should construction waste go? Let's take a closer look.

First, how to deal with construction waste.

While discussing how to deal with construction waste, let's first understand what construction waste is. Construction waste is the discharge of unwanted materials generated during the maintenance, demolition and renovation of buildings.

In our very large cities, most of the construction waste is not properly disposed of, and a lot of it is directly piled up in the open air, which not only occupies land, but also causes serious pollution to the environment. If it is not treated for a long time, it will cause deeper pollution to the soil and groundwater. Therefore, we need to make a reasonable arrangement of construction waste, and the methods are as follows:

1. Personal construction waste can be used as a filling chat for the need for rooms, such as the bathroom area, but it should be noted that the materials should be processed and then used.

2. Construction waste materials can be used to produce thick and fine aggregates for making wall panels, floor tiles and highway pavement bases.

3. The most high-tech is that the recycling technology of construction waste treatment, through the classification of waste in construction waste or reuse after crushing, Jinan began to make relative measures for the reuse of construction waste resources. Construction waste is also very serious for environmental pollution, so if you find that there is construction waste piled up at will, you should report to the relevant departments in time.

Second, construction waste disposal to pay disposal fees.

Units and individuals shall not mix construction waste with domestic waste, especially not hazardous waste mixed with construction waste. The decoration and decoration waste of individual residences shall be collected in bags, placed at designated points, and removed in a timely manner, and it is strictly forbidden to dump them at will.

Property service enterprises should also accept the supervision and guidance of the city, county (district) sanitation department, set up temporary storage points or collection containers for residential decoration waste in the jurisdiction, and organize centralized clearance, and the inability to clear individuals can entrust a professional team to pay for transportation.

Conclusion: The article is about the hazards of construction waste and the introduction of treatment methods, more and more houses are built, and more and more attention should be paid to construction waste. In the past two years, China's treatment of construction waste has also been greatly improved.

The harmony of the society depends on you, me and him, and I also hope that everyone will not pile up construction waste at will, and at the same time realize a green, healthy and beautiful home.

Construction wasteYesMuck, spoil, discarded materials, sludge and other wastes generated by construction, construction units or individuals in the process of construction, laying or demolition and repair of various buildings, structures, pipe networks, etc. According to the different sources of construction waste, it can be divided into construction construction waste and demolition construction waste.

How to deal with construction waste

Many of the wastes in construction waste can be reused as renewable resources after sorting, rejecting or shredding.

Coarse and fine aggregates are produced from abandoned building concrete and waste masonryIt can be used to produce concrete, mortar or prepare building materials such as blocks, wall panels, floor tiles and other building materials of the corresponding strength grade. After the coarse and fine aggregates are added with curing materials, they can also be used for highway pavement base;

Waste bricks and tiles are used to produce aggregatesIt can be used to produce recycled bricks, blocks, wall panels, floor tiles and other building materials;

The muck can be used for road construction, pile foundation filler, foundation foundation, etc

4. For waste wood construction waste, the wood that has not been obviously damaged can be directly reused to rebuild the building, and the wooden components with serious damage can be usedIt can be used as a raw material for wood recycled boards or papermaking;

5. The asphalt mixture of waste pavement can be in an appropriate proportionDirectly used in recycled asphalt concrete

6. Waste road concrete can be processed into recycled aggregateIt is used to prepare recycled concrete

7. Scrap steel, scrap steel bars and other scrap metal materialsIt can be reused directly or recycled

8. Waste glass, waste plastics, waste ceramics and other construction waste are used differently according to the situation;

9. Waste bricks and tiles are burnt clay materials, which have volcanic ash activity when crushed and ground into powder materialsIt can be used as a concrete admixture, replacing fly ash, slag powder, stone powder, etc.

How to dispose of construction waste:

1. The construction waste of the community, including the demolition of buildings, the decoration of houses, and the liquid produced by road renovation, needs to be transported to the corresponding treatment site through the construction waste truck, and the transformation is carried out, so as to be recycled. The owners of the community only need to transport the construction waste generated to the community stacking place designated by the property.

2. The daily construction waste is used as filler, which appropriately reduces the cost of materials and saves the trouble of handling. The commonly used place for construction waste is to make filler in the bathroom, but it should be noted that the construction waste must be disposed of and picked up before use.

3. If it is a large piece of concrete, marble and other construction waste, then it needs to be processed by a crusher, so as to reduce its volume, so that it is better to handle and reuse more simply.

Regulations on the stacking of construction waste in the community:

There are no laws and regulations for the construction waste dumping point in the community, which is generally set by local regulations, and local regulations generally set residents to the community housing committee or property contact service enterprises to register and put them in the designated place. The main provisions are as follows:

1. According to the regulations on the management of decoration garbage in the community, the demolition and removal of non-load-bearing walls need to be approved by Yuanchang professionals before they can be implemented.

2. The newly built partition wall must be made of light materials, and red bricks shall not be used for masonry except for special requirements. If the pipe diameter is greater than centimeter, it shall not be concealed in the load-bearing wall, and the pipe holes of the range hood and exhaust fan that were originally reserved shall not be expanded.

3. The selection should not affect the aesthetics of the park, and the secondary position that is convenient for upside down and cleaning should be selected.

Summary. The disposal of construction waste usually needs to be carried out in accordance with local regulations and environmental protection requirements. Here are some common construction waste disposal methods:

1.Classification**: Classify construction waste according to different materials, such as concrete, masonry, wood, metal, etc.

The materials can be sent to the station or center for reuse to reduce resource waste and environmental pollution. 2.Construction Waste to Landfill:

For construction waste that cannot be reused or reused, there is an option to send it to a legal construction waste landfill. Landfills should meet environmental requirements, and garbage should be properly treated and closed to reduce pollution to soil and water sources. 3.

Construction waste incineration: Some areas can be disposed of using construction waste incineration facilities. The heat energy generated during the incineration process can be utilized while reducing the volume of waste and the need for landfills.

However, the incineration process needs to be strictly controlled to prevent the release of harmful substances. 4.Construction Waste Recycling:

Some construction waste can be converted into reusable building materials through proper treatment and processing. For example, discarded concrete can be crushed and used as recycled aggregate to make new concrete.

For example, discarded concrete seepage can be crushed and used as recycled aggregate, and molds can be used to make new concrete.

When dealing with construction waste, you need to ensure compliance with local regulations and environmental requirements. In addition, measures to reduce the generation of garbage should also be taken during the construction process, such as accurate estimation of the amount of materials, reasonable planning and construction branches, etc., so as to reduce the generation of construction waste.
