采气废水中有机物去除方法/Methods of organic contaminants removal in natural gas-produced wastewater[J]
, 2015 新疆油田天然气开采过程中产生的大量高矿化度、高COD的含油废水,难以处理处置,严重影响了气田的正常生产活动,危害到气田周边土壤安全和荒漠植被的生存.为实现该类废水的达标排放,选取COD和总石油烃含量为考察指标,研究比较了紫外(UV)、臭氧(O3)及紫外臭氧联合处理(UV/O3)法对该类废水的处理效果,进一步考察了pH和O3发生量对UV/O3法处理效果的影响.研究结果表明,3种方法处理废水60 min后,废水COD由处理前的563 mg/L分别下降至处理后的479、334.9和314 mg/L ...
