摘要
由于含有持久性有机污染物(Persistent Organic Pollutants,POPs)的废水排放增加,而传统污水处理技术对POPs基本不具备处理能力,因此造成了极大的环境污染.与传统的光催化技术相比,过一硫酸盐(Peroxymonosulfate,PMS)光催化体系由于增加了新的活性氧硫酸根自由基(SO_(4)^(-)·),且能够促进羟基自由基(·OH)的产生,成为处理POPs的一种有效方法.基于此,本文综述了金属氧化物及非金属催化剂类石墨相氮化碳(g-C_(3)N_(4))分别与PMS联用在降解POPs领域的研究现状,在分析他人研究结果的基础上,对PMS光催化体系的研究方向和重点进行展望.
The rapid development of human civilization has led to an increase in the discharge of wastewater containing persistent organic pollutants(POPs).Because the traditional sewage treatment technology basically does not have the treatment capacity for POPs,it has caused great environmental pollution.Compared with the traditional photocatalytic technology,peroxymonosulfate(PMS)photocatalytic system has become an effective method for the treatment of POPs because it adds a new reactive oxygen sulfate radical(SO_(4)^(-)·)and can promote the production of hydroxyl radical(·OH).Based on this,this paper summarizes the research status of metal oxide and non-metallic catalyst graphite carbon nitride(g-C_(3)N_(4))combined with PMS in the field of degradation of POPs.Based on the analysis of the research results of others,the paper predicts the research direction and focus of PMS photocatalytic system.
