Description

Technical Field

[0001] The utility model belongs to the technical field of waste collection and storage, and particularly relates to a hazardous waste collection and storage box. Background Art

[0002] Hazardous waste storage boxes are important containers specially used to store hazardous waste. They play a key role in hazardous waste management. However, in the current hazardous waste storage process, the inconvenience of separating solids and liquids has brought about a series of problems. This mixed state makes it extremely difficult to accurately classify and identify waste. The inability to clearly distinguish between solid and liquid components will lead to inaccurate assessments of the nature and degree of hazard of the waste, thereby affecting the selection and decision-making of subsequent treatment methods, and may cause inappropriate treatment methods, bringing potential environmental risks. Secondly, it causes great obstacles to subsequent treatment and disposal links. Many treatment technologies are designed for solid or liquid wastes respectively. It is difficult to implement effective treatment measures in a mixed state, which reduces the treatment efficiency and effect. For example, some treatment processes for solids may not be carried out normally due to the presence of liquids, and vice versa, which greatly limits the treatment capacity and progress. In addition, this inconvenient separation will also affect resource recycling. Some solid or liquid components may originally have recycling value, but they are difficult to extract and utilize in a mixed state, resulting in a waste of resources. In order to solve these problems, it is urgent to develop a hazardous waste storage box. Utility Model Content
