Abstract
Description
technical field
[0001] The invention relates to waste water treatment equipment in the field of environmental protection, in particular to a waste water ammonia nitrogen stripping treatment reaction device. Background technique
[0002] With the vigorous development of petrochemical, pharmaceutical, pesticide and fine chemical industries, a large amount of high-concentration ammonia nitrogen wastewater is produced in the process of chemical production. If such wastewater is discharged directly without treatment, it will cause great damage to the water environment.
[0003] At present, the treatment methods for high-concentration industrial ammonia-nitrogen wastewater mainly include: stripping method, steam stripping method, ammonia distillation method, and chemical precipitation method. Among them, the chemical precipitation method has not yet been applied in large-scale engineering due to its high operating cost and complicated operation; the three methods of air stripping,...
