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(guó)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(guò)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(bào)   ISTICEIPKU Journal： CIESC JOURNAL 年，卷(期)： 2010, 61(4) 分類號(hào)： 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(hào)： 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(guó)民經(jīng)濟(jì)發(fā)展    total    開采過(guò)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(zhǎng)江學(xué)者與創(chuàng)新團(tuán)隊(duì)發(fā)展計(jì)劃創(chuàng)新團(tuán)隊(duì)項(xiàng)目
