With the continuous progress of science and technology, ruthenium-containing waste residue waste is increasing in industrial production, which has caused great pollution to the environment. Therefore, ruthenium-containing waste residue has become an important task at present. Ruthenium-containing wastes are mainly used in petrochemical, electronics, electroplating and other industries, which contain a large amount of ruthenium, iridium, platinum, etc., if these wastes are not carried out, they will not only cause pollution to the environment, but also cause waste of resources.
*There are many methods for ruthenium-containing waste residues, the most common of which are fire and wet. The fire method refers to the extraction of metals from ruthenium-containing waste residue through high-temperature smelting, while the wet method refers to the extraction of metals from ruthenium-containing waste residue through chemical reaction. In practical application, according to the nature of ruthenium-containing waste residue and the type of metal contained, different methods are selected.
In addition to ruthenium-containing waste, environmental pollution can also be reduced by reducing the generation of ruthenium-containing waste. For example, measures such as improving production processes, improving equipment efficiency, and strengthening management can all reduce the generation of ruthenium-containing waste. At the same time, supervision should be strengthened, relevant laws and regulations should be formulated, and the generation and management of ruthenium-containing waste residue should be regulated and managed.
There are several main types of ruthenium-containing waste:
1.Ruthenium-containing waste catalysts: Catalysts used in petrochemical, pharmaceutical, fine chemical and other fields will be damaged by reduced activity and impurity pollution to varying degrees during use, thus losing their original catalytic performance. These spent catalysts contain a large amount of ruthenium, iridium, platinum, etc., so they are of high value.
2.Ruthenium-containing wastewater treatment sludge: In the wastewater treatment process, a large amount of sludge will be generated, which contains a large amount of harmful substances such as heavy metal ions and organic matter. These sludges need to be treated and disposed of to avoid secondary pollution to the environment. Because the sludge contains a large amount of ruthenium, iridium, platinum, etc., it can be utilized.
3.Ruthenium-containing exhaust aerosols: During the production process, a large amount of exhaust aerosols will be generated, which contain a large number of harmful substances such as metal particles and organic matter. These exhaust aerosols can be collected and disposed of to avoid pollution to the environment. Because the exhaust aerosol contains a large amount of ruthenium, iridium, platinum, etc., it can be utilized.
4.Ruthenium-containing solid waste: In the production process, a large amount of solid waste will be generated, which contains a large amount of harmful substances such as *** and organic matter. These solid wastes need to be treated and disposed of to avoid pollution to the environment. Because solid waste contains a large amount of ruthenium, iridium, platinum, etc., it can be utilized.
In the process of ruthenium-containing waste residue, the following points need to be noted:
1.Safety first: Since ruthenium-containing waste residue may contain harmful substances, such as heavy metal ions, organic matter, etc., it is necessary to pay attention to safety issues during the treatment process, such as wearing protective clothing, gloves and masks.
2.Environmental protection priority: In the process of ruthenium-containing waste residue, it is necessary to pay attention to environmental protection issues, such as reducing secondary pollution and rational use of resources.
3.Benefit maximization: In the process of ruthenium-containing waste residue, it is necessary to pay attention to the problem of benefit maximization, that is, to improve the efficiency as much as possible, reduce costs and improve product quality.
4.Standardized management: In the process of ruthenium-containing waste residue, it is necessary to pay attention to standardized management issues, such as establishing a sound system, strengthening supervision and formulating relevant laws and regulations.
Ruthenium-containing waste residue is an important environmental protection work, which can reduce environmental pollution, save resources and improve economic benefits. In practical application, it is necessary to select appropriate methods and technologies according to the specific situation, and at the same time strengthen management and supervision to ensure the smooth progress and sustainable development of the work.
