摘要
我国正处于工业化与城市化的快速发展时期,高浓度氨氮废水的大量排放给生态环保与国民安全带来了巨大的挑战.本文首先总结了目前在工业生产领域中常见的处理方法为生物法和物化法,如生物脱氮法(生物法)、折点氯化法(物化法)、化学沉淀法(物化法)、吹脱法(物化法)等.随后,从解决常规吹脱法中存在的易堵塞等问题出发,综述了负压脱氨技术的研究现状,重点介绍了负压脱氨技术原理及其技术的发展与应用,以期为高浓度氨氮废水处理的工程化应用提供支持.
Abstract
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.
