微波技术在油田采出废水处理中的作用
Abstract：The process of microwave flocculation and Fe/C micro-electrolysis was used to treat several oilfield production wastewater, and the effects of microwave on flocculation, disinfection, de-oiling and decrease of the corrosion rate were investigated.The results showed that microwave coagulation could reduce 20% dosage for PAC and 30% for PAM, and the settling time of microwave flocculation was only 1/4 of normal flocculation, and total removal efficiency of COD for the wastewater reached 96%.Microwave could effectively kill total growth bacteria (TGB) and sulfate-reducing bacteria (SRB) in the wastewater, and the removal of bacteria reached 99%.Microwave accelerated oil-water separation and promoted emulsion-breaking simutaneously, and the average removal efficiency of oil was 95%.Microwave also played an active role in the reduction of corrosion rate, and the average corrosion reduction reached 90% in the microwave assisted process, which was 10 points higher than that in normal process.摘要： 引言 油田的开采在国民经济发展中发挥着重大作用,但随着现代产技的发展和人民生活水平的提高,环境保护日渐受到重视,因此油田开采过程中所产生的大量污染废水治理就显得尤为重要~([1]). 作者： 廖建波卜龙利张爱涛 Author： LIAO Jianbo BO Longli ZHANG Aitao 作者单位： 西安建筑科技大学环境与市政工程学院,陕西,西安,710055 期 刊： 化工学报 ISTICEIPKU Journal： CIESC JOURNAL 年，卷(期)： 2010, 61(4) 分类号： X741 关键词： 微波 油田采出废水 絮凝 铁/炭微电解 Keywords： microwave oilfield production wastewater flocculation Fe/C micro-electrolysis 机标分类号： TU9 TG1 机标关键词： 微波技术 油田 废水处理 production wastewater treatment microwave coagulation removal efficiency corrosion rate 人民生活水平 国民经济发展 total 开采过程 环境保护 废水治理 results points oil active 污染 time 基金项目： 陕西省教育厅专项基金，教育部长江学者与创新团队发展计划创新团队项目【微波技术在油田采出废水处理中的作用】相关文章：
