I. Introduction.
As an important branch of the manufacturing industry, the leather industry plays an important role in providing leather products needed for daily life. However, this industry also brings with it some environmental problems, especially pollution. This article will discuss in detail the main ones caused by the pollution caused by tanneries.
2. Wastewater pollution.
The tannery production process generates a large amount of wastewater containing organic and chemical substances. If this wastewater is discharged directly without treatment, it will cause serious pollution to the water source and pose a threat to the surrounding environment and the health of residents.
3. Air pollution.
The tannery produces a large amount of organic waste gases in the production process, such as the exhaust gas from the degreasing and dyeing process of fur, as well as harmful gases such as hydrogen sulfide and nitrogen oxides produced in the tanning process. If these exhaust gases are not directly discharged after treatment, they will cause serious pollution to the atmospheric environment and have an impact on the health of surrounding residents.
4. Noise pollution.
The machinery and equipment of the tannery will produce a lot of noise during operation, which will have an impact on the quality of life of the surrounding residents and even cause harm to human health.
5. Solid waste pollution.
The waste of the tannery mainly includes fur, waste residue, waste materials, etc., which will cause pollution to the environment if not properly treated, and will also occupy a lot of land resources.
6. Summary. In general, the pollution caused by tanneries mainly includes wastewater pollution, air pollution, noise pollution and solid waste pollution. In order to protect the environment, we must strengthen the supervision of tanneries and promote their adoption of environmentally friendly technologies to achieve green production.
