Whatpollutiondoesheavymetalwastecause?

With the increase of population and the continuous development of industry, the amount of various kinds of waste is also on the rise. Therefore, waste not only occupies resources, but also pollutes the environment, so their recycling and treatment is an important issue. There are a lot of waste, such as plastic products, metal waste, rubber products, among which the recycling of metal waste, as well as the recycling of plastic metal mixture, people mainly use metal shredder equipment for shredding and recycling.

 

As heavy metal wastes account for a large proportion of all types of hazardous wastes, they harm the environment in various ways. In the treatment, except some of them can be recycled, most of them need to be stabilized to achieve the goal of harmlessness. Some solid waste in metallurgical industry cannot be directly discharged into the environment due to the contamination of leachable heavy metals and other pollutants.

 

Conventional technology types (such as application more cement or lime solidifying law) a lot, but when used in heavy metal waste treatment has limitations, especially affected by the PH change, when the PH is low, heavy metal waste treatment has limitations, especially affected by the PH change, when the PH is low, heavy metal ions will dissolve out, did not reach the purpose of long-term stabilization, in the final disposal, will produce secondary pollution, increase cement lime can improve the stability and reduce leaching rate, but the processing costs and cured volume also will increase.

 

Whether it is cement or incineration, it will cause some pollution to the environment. Therefore, the emergence of metal shredder is not only an effective solution to environmental pollution, but also a rational use of resources. It is a major discovery of environmental protection equipment.
