Description

Technical Field

[0001] The utility model belongs to the technical field of wastewater treatment, in particular to a device for treating industrial wastewater containing medium or high concentration thallium. Background Art

[0002] Treatment plants for medium- to high-concentration thallium-containing industrial wastewater are designed to treat industrial wastewater containing high concentrations of thallium. These plants typically utilize technologies such as chemical precipitation, ion exchange, and membrane separation to effectively remove thallium ions from the wastewater, ensuring compliance with environmental emission standards. These plants typically require rigorous process design and operational management to ensure safe and efficient treatment of thallium-containing industrial wastewater.

[0003] Thallium industrial wastewater treatment refers to the treatment of industrial wastewater containing thallium pollutants to meet environmental emission standards or reuse requirements. Thallium is a toxic metal that poses serious hazards to the human body and the environment. Therefore, the treatment of thallium industrial wastewater is very important. Appropriate precipitants, such as sodium hydroxide, sodium sulfide, etc., are used to precipitate thallium ions in the wastewater into solids, and then separate and treat them. Ion exchange resins can selectively adsorb thallium ions and remove them from the wastewater, thereby reducing the concentration of thallium ions. The ion exchange process can effectively remove heavy metal ions in the wastewater, improve the water quality of the wastewater, and make it meet environmental emission standards. Treating thallium-containing industrial wastewater through ion exchange technology can effectively reduce pollution to the environment and protect water resources and the ecological environment. Ion exchange technology is relatively mature, simple to operate, and has relatively low maintenance costs. It includes membrane technologies such as reverse osmosis and ultrafiltration, which can effectively isolate ions and pollutants in wastewater and improve water quality. Oxidants such as hydrogen peroxide and sodium perchlorate are used to oxidize the wastewater to convert thallium ions into a more easily handled form. Through bioreactors or bioreactors, the wastewater is oxidized and converted into a more easily handled form. Biological treatment equipment such as filter tanks use microorganisms to degrade organic matter and some inorganic matter in wastewater, including thallium ions, and combine multiple treatment methods, such as chemical and physical combination, biochemical combination, etc., to comprehensively remove thallium pollutants in wastewater. The treatment of thallium industrial wastewater requires selecting appropriate treatment processes and equipment according to specific circumstances, conducting process design and operation management, and ensuring that the wastewater is effectively treated and no longer causes harm to the environment and human body. The problem with the above technology is that in the process of centralized storage and pretreatment of thallium wastewater, it is necessary to store it in a treatment tank and add additives to the inner cavity of the treatment tank for preliminary pretreatment. However, the inner cavity of the treatment tank does not have a component that can mix and dilute the thallium wastewater and the additive. Therefore, it takes a certain amount of sedimentation to achieve the effect of fully mixing and diluting the thallium wastewater and the additive. The process will consume a lot of time and cost, so it is not convenient for users to quickly carry out centralized treatment of large amounts of thallium wastewater. Utility Model Content
