Countries around the world generally recognize the importance of protecting the environment. China has listed environmental protection as a basic national policy. Strict requirements are required to prevent and control pollution problems in industrial production. Therefore, in the wet production of zinc , it is necessary to develop in the direction of cleaner production.
According to the wet zinc smelting process, there are the following problems, and adequate attention should be given to environmental protection:
(1) Prevention and control of dust pollution during transportation and use of raw materials;
(2) Pollution and prevention of flue gas (SO 2 ) during roasting;
(3) Utilization of waste residue and prevention of pollution;
(4) The recycling and discharge of wastewater meets environmental protection requirements.
At present, there are many writings in the above four aspects, and will not be repeated here. However, it should be pointed out that there are some strong environmental protection measures in the large and medium-sized wet zinc smelting plants, and the environment has been greatly improved, but the pollution in the small wet zinc smelting plant environment is still serious. The government's environmental protection department should give strong and strict supervision.
In short, in the environmental protection of wet zinc smelting, no matter whether there is a big gap between large factories or small factories and clean production, efforts should be made to improve and strengthen the bare ring measures and improve the environment.
