微波技術(shù)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(jīng)濟(jì)發(fā)展中發(fā)揮著重大作用,但隨著現(xiàn)代產(chǎn)技的發(fā)展和人民生活水平的提高,環(huán)境保護(hù)日漸受到重視,因此油田開采過程中所產(chǎn)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(xué)環(huán)境與市政工程學(xué)院,陜西,西安,710055 期 刊: 化工學(xué)報   ISTICEIPKU Journal: CIESC JOURNAL 年,卷(期): 2010, 61(4) 分類號: X741 關(guān)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(jī)標(biāo)分類號: TU9 TG1 機(jī)標(biāo)關(guān)鍵詞: 微波技術(shù)    油田    廢水處理    production wastewater    treatment    microwave coagulation    removal efficiency    corrosion rate    人民生活水平    國民經(jīng)濟(jì)發(fā)展    total    開采過程    環(huán)境保護(hù)    廢水治理    results    points    oil    active    污染    time 基金項(xiàng)目: 陜西省教育廳專項(xiàng)基金,教育部長江學(xué)者與創(chuàng)新團(tuán)隊發(fā)展計劃創(chuàng)新團(tuán)隊項(xiàng)目
