Abstract: This paper will elaborate on the evaluation of rural steel structure demolition from five aspects, including cleaning and replacement before demolition, equipment after demolition, sludge reduction, waste liquid treatment, oil tank demolition, hazardous waste treatment, environmental protection construction, and the demolition case of Baros Group's chemical plant and the application of waterjet cutting technology. The assessment of the demolition of rural steel structures needs to be comprehensively considered according to the actual situation, and a comprehensive risk assessment and environmental impact assessment should be carried out.
1. Cleaning and replacement.
Before the demolition of the rural steel structure, the demolition object needs to be cleaned and replaced. First of all, it is necessary to empty the harmful gases and liquids and completely clean the storage equipment;Secondly, the chemicals and dirt on the surface of the demolition object also need to be cleaned so as not to endanger the health of the construction personnel. In addition, the cleaning process needs to be measured and inspected to ensure that the cleaning effect meets the requirements.
In the case of the demolition of the chemical plant of the Baros Group, a comprehensive cleaning and replacement work was carried out before the demolition, and the equipment to be dismantled was fully emptied and cleaned to ensure the safe progress of the demolition work.
2. Equipment**.
For equipment that is still in use, it is necessary to carry out ** when dismantling work, and repair or secondary sale. This not only saves resources, but also contributes to environmental protection. At the same time, the equipment can help enterprises reduce the cost of demolition and improve economic benefits.
In the case of the dismantling of the chemical plant of the Baros Group, the dismantled equipment was carried out and re-sold, realizing the effective use of resources.
3. Sludge reduction and waste liquid treatment.
The disposal of hazardous waste is a crucial part of the demolition work. If not treated effectively, it will cause great harm to the environment. Therefore, the resulting waste liquid and sludge need to be treated comprehensively during the demolition process. Some modern sludge reduction technology and waste liquid treatment technology can effectively reduce the volume and toxicity of waste and achieve environmental protection effect.
In the case of the dismantling of the chemical plant of the Baros Group, the waste liquid and sludge after the demolition were treated with sludge reduction and waste liquid treatment, which effectively protected the environment and ecosystem.
4. Tank dismantling and hazardous waste treatment.
In the process of dismantling rural steel structures, there is a large amount of hazardous waste, including oil tanks. Removing a tank requires an environmental assessment and risk assessment, as well as the selection of appropriate technology for dismantling. At the same time, it is necessary to carry out comprehensive hazardous waste treatment work, and transport hazardous waste to a special treatment center for treatment.
In the case of the dismantling of the chemical plant of the Baros Group, the removal of the oil tank was carried out using the Barros immovable fire waterjet cutting and demolition technology to ensure the safety and environmental protection requirements of the dismantling process. At the same time, a comprehensive hazardous waste treatment work has been carried out to ensure the safe disposal of hazardous waste and environmental protection.
5. Environmental protection construction.
When dismantling rural steel structures, environmental protection factors need to be fully considered. During the construction period, it is necessary to classify and dispose of garbage, rationally use energy resources, and ensure the environmental protection of the construction process.
In the case of the demolition of the Baros Group's chemical plant, we used environmentally friendly construction materials and strictly implemented environmentally friendly construction procedures to ensure the environmental protection of the construction process.
To sum up, the evaluation of rural steel structure demolition needs to comprehensively consider many factors such as safety, environmental protection, economic and social benefits. Reasonable cleaning and replacement, equipment, sludge reduction, waste liquid treatment, oil tank dismantling, hazardous waste treatment and environmental protection construction can protect the environment and ecosystem to the greatest extent, and at the same time, it can also make the demolition work more efficient and economical.
