When dealing with solid waste, the principles of "minimization, resource utilization, harmlessness and sustainable development" should be followed, and the concept of circular economy and green development should be implemented.
Solid waste should be categorized according to recyclable, hazardous, wet and dry waste, and put into the corresponding garbage cans or recycling facilities. This helps to recycle resources and reduce pollution to the environment. Recyclable solid waste items (e.g. paper, glass, plastics, metals, etc.) are sorted and recycled, processed and reused. Recycling reduces the need for raw materials, energy consumption and environmental impact.
The non-recyclable and hazardous solid waste is treated by incineration. Solid waste is burned at high temperatures to generate heat and the flue gases are treated through purification facilities to minimize environmental pollution. Solid waste that cannot be recycled and incinerated is buried in landfills. Solid waste decomposes gradually in landfills, but it produces harmful gases and leachate that pollute soil and water. Therefore, landfills require the selection of suitable sites and strict management.
Some solid wastes belong to special categories, such as hazardous wastes, medical wastes, electronic wastes, etc., which need to be treated according to their characteristics. For example, hazardous waste requires specialized collection, storage and treatment to prevent harm to the environment and human health.?
Precautions for treating solid waste
1. Safe storage: solid waste needs to be stored safely before treatment to avoid leakage or other hazards. Use suitable containers for sealing and labeling, and placed in a special solid waste storage area, away from ignition sources and flammable materials.
2, choose the appropriate treatment: according to the nature and quantity of solid waste, choose the appropriate treatment. For example, physical treatment, chemical treatment, incineration, landfill and so on. Ensure that the treatment method meets the requirements of environmental protection and minimizes the impact on the environment.
3. Safe operation: When dealing with solid waste, it is necessary to take safe operation measures, including wearing personal protective equipment, avoiding direct contact with hazardous substances, breathing harmful gases and so on. Follow the relevant operating procedures and safety guidelines to ensure the safety of personnel and the environment.
4. Monitoring and recording: The solid waste treatment process is monitored and recorded, including the source, quantity, treatment method and treatment effect of solid waste. This helps to trace and evaluate the treatment effect, as well as meet the requirements of regulators and stakeholders.
