摘要
为使煤矿矿井水达到排放标准,考察了不同方法去除煤矿矿井水中的微污染物(以乳化油为主)的效果,其中单一活性炭吸附对乳化油的去除率约80%,臭氧氧化与紫外光氧化对水中乳化油去除率分别为79%和62%。当2种氧化方法结合活性炭吸附时,乳化油去除效果显著提高,去除率均达到98%以上。
To meet the requirement of discharge standard, various methods were investigated for the treatment of micro-pollutants(mainly emulsified oil) in coalmine wastewater. It was found that activated carbon(AC) adsorption process alone could be used to remove about 80% of emulsified oil, whilst either ozone or UV oxidation could be done for 79% or 62% removal, respectively. When using both oxidation processes combined with AC adsorption, the emulsified oil removal rate would reach over 98%.
