Since the end of the 20th century, due to the acceleration of the upgrading of high-tech products, more and more cars, computers, TVs and mobile phones have been discarded. As a result, the environmental pollution caused by toxic metal mercury has become increasingly worrisome. Mercury pollution refers to the mercury and mercury compounds on the environment pollution, is one of the heavy metal pollution. Mercury comes mainly from the atmosphere, soil and water. Combustion of coal and oil, smelting of mercury-bearing metallogenic minerals, emissions from industries that use mercury as feedstock, and energy-saving waste lights that are discarded in everyday life are the major sources of mercury in the atmosphere; the use of mercury-containing pesticides and mercury-containing Sludge fertilizer is the main source of mercury in the soil; chlor-alkali
