摘要:

垃圾渗滤液中某些顽固性有机化合物以其紫外线猝灭特性降低了废水的紫外线透射率,进而干扰相关的消毒功效。紫外猝灭物质(UVQS)主要由腐殖酸(HA)、黄腐酸(FA)和亲水性有机物(HPI)三部分组成,不同的处理过程表现出各异的特征和行为。综述了UVQS的相关信息以及可行的技术处理UVQS的研究现状,结果表明,电催化氧化和光催化氧化的降解效果最佳,UVQS类物质去除率最高分别可达95%和98.95%。针对不同质量分数UVQS的去除进行协助优化处理,可以更好地认识和理解UVQS的降解对废水处理的重要性。

Abstract:

Some refractory organic compounds in landfill leachate with UV quenching characteristics reduce the UV transmittance of wastewater, thereby interfere the related disinfection efficacy. Ultraviolet quenching substance(UVQS) consist of three major fractions, humic acids(HA), fulvic acids(FA) and hydrophilics(HPI), each of which has distinct characteristics and behaviors during different treatment processes. The relevant information of UVQS and the research status of feasible technology to deal with UVQS are summarized. Among of them, electrocatalytic oxidation and photocatalytic oxidation has the superior degradation effects, the highest removal rates of which are up to 95% and 98.95% on UVQS substances respectively. And the removal of UVQS with different quality scores is assisted in optimizing treatment, so as to better cognize and understand the importance of UVQS degradation in wastewater treatment.

Key words: landfill leachate, ultraviolet quenching substance, UVQS processing technology, advanced oxidation
