微波技術在油田采出廢水處理中的作用

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 油田的開采在國民經濟發展中發揮著重大作用,但隨著現代產技的發展和人民生活水平的提高,環境保護日漸受到重視,因此油田開采過程中所產生的大量污染廢水治理就顯得尤為重要~([1]). 作者： 廖建波卜龍利張愛濤 Author： LIAO Jianbo  BO Longli  ZHANG Aitao 作者單位： 西安建筑科技大學環境與市政工程學院,陜西,西安,710055 期 刊： 化工學報   ISTICEIPKU Journal： CIESC JOURNAL 年，卷(期)： 2010, 61(4) 分類號： X741 關鍵詞： 微波    油田采出廢水    絮凝    鐵/炭微電解    Keywords： microwave    oilfield production wastewater    flocculation    Fe/C micro-electrolysis    機標分類號： TU9 TG1 機標關鍵詞： 微波技術    油田    廢水處理    production wastewater    treatment    microwave coagulation    removal efficiency    corrosion rate    人民生活水平    國民經濟發展    total    開采過程    環境保護    廢水治理    results    points    oil    active    污染    time 基金項目： 陜西省教育廳專項基金，教育部長江學者與創新團隊發展計劃創新團隊項目
