Cold Plasma Generation Technology Is Another Way For Leather Factory Sewage Treatment.

With the extensive use of leather materials in many industrial fields, the "three wastes" produced by leather processing are also increasing. Under the situation of increasingly obvious contradiction between economic development and environmental protection, the pollution control of leather industry requires not only macroeconomic regulation and control of government policies, but also the regulation of the leather industry. Need New sewage technology and production equipment have been continuously researched in the industry. Recently, cold plasma generation technology has been applied in leather pollution control.

In view of the low temperature in winter in northern China, Shandong Laizhou Qing Zhi environmental protection equipment research institute is committed to applying cold plasma generation technology to sewage treatment in low temperature environment and has achieved success.

It is reported that most sewage treatment plants use activated sludge process to treat sewage, that is, mainly through the role of microorganisms to remove organic pollutants in sewage. Low temperature has a significant effect on the removal rate of organic matter. When the water temperature is below 13 C, the treatment effect of activated sludge system drops sharply. When the water temperature is below 4 C, there is almost no treatment effect.

According to the introduction, this technology is not affected by the water temperature. Even if the water temperature is less than 4 degrees, it can also carry out sewage treatment. There is no water quality requirement for the sewage of the industry, and the cold plasma treatment has more powerful oxidation capacity.

　　 meanwhile This technology greatly shortened the sewage treatment cycle, and cold plasma treatment did not involve microbial cultivation. Due to the perfection of cold plasma generation technology, its cost and operation cost are lower than the conventional two stage biological treatment method, which has obvious economic advantages.

　　 Leatherwear The treatment of industrial pollution is not only a result of the environment, but also a part of leather production enterprises' transformation and upgrading.
