摘要:

随着工业规模的扩张,难降解废水的类型和排放总量逐年递增,产生的废水具有较高生物毒性,寻求高效能的难降解废水处理技术成为研究趋势。利用自由基的高氧化能力直接矿化污染物或通过改变分子结构提高污染物的可生化性,是当前处理难降解废水的主流思路和有效途径。过硫酸盐氧化是一种新兴的难降解废水高效处理技术,活化后会产生以·OH和SO4 •-为主的多种活性自由基。其具有较强的氧化性能,在多种难降解废水处理实验中得到验证。综述了过硫酸盐氧化技术处理垃圾渗滤液、印染废水、化工废水、含新兴污染物废水等难降解废水的最新研究进展,对不同活化方式包括物质输入型、能量输入型和物质-能量耦合输入型的过硫酸盐活化反应机制、废水处理效果及技术经济性能进行了探讨,并对该技术的发展方向和工程应用前景提出展望,以期为活化过硫酸盐氧化技术的发展和工程应用提供有益参考。

Abstract:

With the rapid development of industries, the types and amount of refractory wastewater discharge are increasing, and the wastewater is highly bio-toxicity. It has become a trend to seek high efficiency technologies for treatment of refractory wastewater. Using high oxidation capacity of free radicals to mineralize pollutants directly or to improve the biodegradability of pollutants by changing the molecular structure is the mainstream idea and effective way to treat refractory wastewater. Persulphate oxidation is an emerging technology for efficient treatment of refractory wastewater. It generates a variety of reactive radicals mainly including ·OH and SO4 •-, which have strong oxidation performance and have been verified in the treatment of refractory wastewater experiments. The latest research progresses of persulphate oxidation for the treatment of refractory wastewater such as landfill leachates, dyeing wastewater, chemical wastewater, and wastewater containing pharmaceuticals and personal care products were reviewed. The reaction mechanisms, wastewater treatment efficiencies and techno-economic performance of various activation method including substance-input, energy-input and coupled substance-energy-input activated persulphate oxidation were discussed. The development direction and engineering application prospects of the technology were also presented, with a view to provide useful references for the development and engineering application of activated persulphate oxidation technology.

Key words: persulphate, activation, oxidation, refractory wastewater
