First, the construction waste project declaration and docking process
First of all, such projects are generally led by local urban management departments. After 19, including Anhui, Jiangsu, Henan, Hubei, Shandong, Zhejiang, Xi 'an and other places, the leaders of the municipal party committee put the disposal of construction waste in a more important position. The administrative units at the district and county levels suggested that the construction waste resource treatment plant should be implemented to solve the fundamental problem of urban development, which has been put on the political agenda in various places.
Generally, the willing party will take the lead in submitting the feasibility study and analysis report, project proposal and project implementation plan for the construction of XX (city, district and county) construction waste comprehensive treatment plant to the local government (or Development and Reform Commission and Urban Management Bureau). The information provided should explain the total amount, harm, treatment status, technical advantages, technical strength, market feasibility, environmental protection review, investment scale, land use scale and preferential policies required by the government.
After the joint trial is passed, the National Development and Reform Commission will go through the formalities of "project approval and registration" and issue a "project approval and registration certificate"; Or directly sign an intention agreement with the local government to build XX (city, district, county) construction waste comprehensive treatment plant.
The landing form of the project can be undertaken and operated independently by the enterprise, or it can be built in cooperation with local Chengfa, Huantou and Chengtou Group. Enterprises are dominant, and the whole process is scientific and reasonable.

Second, the procedures and steps of the construction waste treatment plant
1, according to the investment project, such as a county comprehensive garbage treatment plant, set up a legal person company;
2. In the name of the newly established comprehensive garbage treatment plant company, submit the application documents for comprehensive garbage treatment project to the local government and competent department where the general garbage treatment project is invested. With the approval of the local government, the local land and resources bureau, construction bureau and environmental protection bureau may be invited to cooperate in site selection. The site selection of the comprehensive garbage treatment plant is required to be about one kilometer away from the village and as far away from the village as possible. If you are close to the village, you should choose the downwind where there are many people in the village.
3. Find the technical personnel of the company that produces complete sets of construction waste equipment to determine the process scheme of the waste comprehensive treatment plant, determine the BT and BOT operation modes, make a reasonable process layout, fully consider the government requirements and the enterprise's own profit model, and make a project proposal for the waste treatment plant;
4. The newly established waste treatment plant company signed a franchise agreement with the local government for municipal solid waste;
5. Entrust the design institute to make a feasibility study report and get the approval of the development and reform commissions at all levels;
6. Entrust a qualified local EIA department to make an environmental impact assessment report, which shall be examined and approved by the local development and reform commission;
7. After the feasibility study report and environmental impact assessment report of the comprehensive garbage treatment plant come out, you need to get the approval from the local development and reform commission, and you can apply for project subsidies and national debt funds in this province and this city;
8. After the feasibility study report and the environmental impact assessment report are completed, construction can be started and other formalities can be handled when the local government agrees to the construction approval and the land site selection opinions of the land department.

Third, the equipment needed to deal with construction waste
Construction waste contains a lot of steel bars, concrete and brick materials, and recycling these materials is a common and feasible scheme. Broken construction waste can be used as sand, such as concrete blocks, gravel blocks, brick fragments, waste mortar, asphalt blocks and other wastes in construction waste, which are treated by crushing, sand making, screening and cleaning. Large gravel and concrete blocks can be broken into coarse sand with a specification of more than 0.5 mm, medium sand with a specification of 0.5-0.35 mm and 2-4 stones. The finished product is excellent, the grain shape is good and clean. Stones and sand produced by crushing and sand making are used as sand aggregates for buildings and concrete for slabs and beams.
Through sand making and washing, construction waste can be reused for processing and production. One of the more commonly used is the fixed sand production line, which is generally composed of coarse crushing, medium crushing, sand making, sand washing and screening equipment. It can crush raw materials such as construction waste into about 30 kinds of finished products, and the specifications of finished sand are controllable.
Sand washing equipment is essential in the sand production line of construction waste, and it is one of the essential sand washing equipment. The series of sand washing machines directly sold by Luoyang Metso Factory are sand washing machines for sand and gravel (artificial sand and natural sand), which can wash and separate stone powder, soil and other substances in sand and gravel, and have the purpose of cleaning and dewatering. Like other mechanical equipment series, wheel bucket sand washer, sand washer recovery machine, wheel bucket sand washer, double helix sand washer and other products are widely used in washing operations in construction sites, sand mills, concrete dam sites of hydropower stations, metallurgy, building materials, hydropower and other industries. Its novel sealing structure, adjustable overflow weir plate and stable transmission device ensure the effect of cleaning and dewatering, and the production and processing cost is low.
