With the acceleration of industrialization and urbanization, the amount of solid waste generated is increasing year by year, which has caused considerable pressure on the environment. In order to better protect the environment, the classification and treatment of general solid waste and hazardous waste is particularly important. First of all, let's understand the classification of general solid waste.
1. Classification of general solid waste.
General solid waste is mainly divided into two categories: industrial solid waste and domestic solid waste.
1.Industrial solid waste: mainly solid waste generated in the process of industrial production. For example, the production process of machinery manufacturing, chemical industry, mining and other industries will produce a large amount of industrial solid waste. These wastes are diverse, complex in composition, and difficult to dispose of.
2.Domestic solid waste: mainly the waste generated in daily life in the city. For example, food waste, plastics, paper, metals, etc. These wastes are characterized by large quantities and high value.
2. The difference between general solid waste and hazardous waste.
Hazardous wastes are a class of solid wastes that have one or more hazardous properties such as toxic, corrosive, flammable, reactive, or infectious. Compared with general solid waste, hazardous waste is more hazardous.
1.Different treatment requirements: the treatment of general solid waste is mainly harmless, while hazardous waste needs special treatment according to its characteristics and composition to reduce the harm to the environment.
2.Different treatment costs: Due to the special nature of hazardous waste, its treatment cost is usually higher than that of general solid waste.
3.Different hazards: Due to its special nature, hazardous waste will cause great harm to the environment and human health if it is not properly treated.
3. Common ways to destroy general solid waste.
1.Landfill method: This is currently the most commonly used method of solid waste disposal. By filling solid waste into a specific site, it is degraded by using natural conditions such as soil and microorganisms. This method is simple and low-cost, but it occupies a large area and is prone to soil and groundwater pollution.
2.Incineration method: Solid waste is reduced and harmless through high-temperature incineration. This method has a large treatment capacity and good reduction, but the investment is large and has a great impact on air quality.
3.Biological treatment: The metabolic action of microorganisms is used to convert organic matter into stable inorganic matter. This method is environmentally friendly, but it has a long processing cycle and a large footprint.
In order to better protect the environment and reduce the impact of solid waste on the environment, we need to reduce the generation of solid waste from the source, and classify and treat it reasonably. For general solid waste, reasonable classification and effective treatment methods can reduce its impact on the environment; For hazardous waste, strict regulatory measures and special treatment methods are required to ensure that it does not cause harm to the environment and human health.
