Progress in Conventional Treatment Methods and New Negative Pressure Ammonia Removal Technologies for Ammonia Nitrogen Wastewater
China is currently in a period of rapid development in industrialization and urbanization,and the large discharge of high concentration ammonia nitrogen wastewater poses a huge challenge to ecological environmental protection and national safety.This paper first summarizes the common treatment methods in the industrial production field at present,including biological method and physicochemical method,such as biological denitrification method(biological method),breakpoint Chloride process method(physicochemical method),chemical precipitation method(physicochemical method),blow off method(physicochemical method),etc.Subsequently,starting from solving the problems of easy blockage in conventional blowing off methods,the research status of negative pressure deamination technology was reviewed,with a focus on introducing the principle of negative pressure deamination technology and its development and application.This review aims to provide support for the engineering application of high concentration ammonia nitrogen wastewater treatment.
