Alum is a common ore that is characterized by being fine and not easily precipitated. It is a product produced by the reaction of sulfur-containing iron ore with copper sulfide ore, and is commonly found in coal mine tailings and wastewater. The production of alum flowers has a certain impact on the environment and human health, and appropriate measures need to be taken to deal with it.
Use backgrounds. The coal mining industry is one of the main producers of alum. In the process of coal mining and processing, a large amount of wastewater is generated, which contains a large amount of sulfurous wastewater. When this wastewater comes into contact with iron ore and copper sulfide ore, the reaction forms alum. The fine particles of alum make it difficult to precipitate, so that the sulfur-containing alum particles in the wastewater are suspended in the water, which brings certain harm to the environment and the human body.
Impact on the environment.
1.Water pollution: Alum particles in sulfur-containing wastewater are suspended in the water, making the water body turbid and reducing the water quality. This will not only affect the living environment of aquatic organisms, but also bring certain problems to domestic and industrial water.
2.River siltation: After the alum particles enter the river with the wastewater, they will gradually precipitate at the bottom of the river, resulting in an increase in siltation, aggravating the silt layer of the river, affecting the hydraulic conditions of the river, and thus affecting the balance of the water flow and the ecological environment of the river.
Effects on human health.
1.Water pollution: If alum flowers are suspended in drinking water, it may cause water pollution and endanger human health. Substances such as iron and sulfur contained in alum flowers are harmful to human health.
2.Respiratory diseases: Alum flower particles are suspended in the air for a long time, which is easy to be inhaled into the respiratory tract by the human body, and long-term exposure to high concentrations of alum flower particles may lead to the occurrence of respiratory diseases.
Alum flower treatment method.
When handling alum flowers, appropriate measures should be taken to reduce their impact on the environment and the human body.
1.Comprehensive utilization: Alum can be used to produce chemical raw materials such as iron sulfate and copper sulfate to reduce resource waste and environmental pollution.
2.Sedimentation separation: The use of physical and chemical methods, such as gravity sedimentation, centrifugal sedimentation and drug precipitation, etc., to precipitate the alum flower particles to reduce their pollution to water bodies and rivers. Commonly used treatment methods also include sedimentation tanks, filters, etc.
3.Separation process improvement: Some advanced processes and technologies, such as electrochemical separation, membrane separation, etc., can more effectively separate alum flowers from wastewater and improve the separation effect.
Summary. Alum is a fine and non-precipitating ore that has a certain impact on the environment and human health. In order to reduce pollution to the environment and protect human health, appropriate treatment methods need to be adopted. Comprehensive utilization, precipitation separation and separation process improvement are common methods for treating alum flowers. Through reasonable treatment and management, the environmental problems caused by alum flowers can be effectively reduced and sustainable development can be achieved.
