Abstract
Description
technical field
[0001] A biological desulfurization device that converts sulfur-containing compounds into elemental sulfur. Specifically, it is a set of devices that can remove sulfur compounds in flue gas and wastewater and recover elemental sulfur through high-efficiency bioreactors and integrated automatic control. Background technique
[0002] In the atmospheric environment, sulfur dioxide emitted by humans has become the primary pollutant, especially in my country. my country's most important primary energy is coal, accounting for about 70% of my country's energy consumption. Coal usually contains 0.25% to 7% sulfur, and the SO produced during the combustion process 2 It is discharged into the atmosphere along with the flue gas, causing acid rain. According to statistics, in 2005, the total emission of sulfur dioxide in the country was 25.49 million tons, exceeding the total control target (18 million tons) by 7.49 million tons, of which the total emission of industr...
