【摘要】：電驅(qū)動(dòng)膜技術(shù)是開發(fā)較早并在工業(yè)上應(yīng)用較為廣泛的膜分離技術(shù)之一。本論文提出了采用電驅(qū)動(dòng)膜技術(shù)處理高含鹽廢水和重金屬?gòu)U水,目的是解決高含鹽廢水及重金屬?gòu)U水等難處理污水的處置,電驅(qū)動(dòng)膜法根據(jù)自身的工作原理,適合處理這兩種廢水,這種方法的優(yōu)點(diǎn)是處理后可以達(dá)標(biāo)排放,缺點(diǎn)是濃水需要進(jìn)一步處理。本文以模擬溴化鈉代表高含鹽廢水,以模擬銅離子代表重金屬?gòu)U水,采用電驅(qū)動(dòng)膜處理的方法進(jìn)行研究,研究以膜對(duì)電壓、電流密度、濃度變化、能耗為主要操作參數(shù),研究不同的參數(shù)對(duì)處理效果的影響,處理結(jié)果以是否可以達(dá)到達(dá)標(biāo)排放為主。電驅(qū)動(dòng)膜研究高鹽廢水的結(jié)果表明,當(dāng)溴化鈉的濃度約為15000mg/L,經(jīng)過(guò)設(shè)備處理后濃度可最低降至115 mg/L,這時(shí)水中的鹽度遠(yuǎn)低于排放標(biāo)準(zhǔn),這種工藝可以被用來(lái)去除溴化鈉。電驅(qū)動(dòng)膜研究重金屬?gòu)U水的結(jié)果表明,銅離子的濃度停留在約150mg/L時(shí),能耗和處理效果達(dá)到最優(yōu)的結(jié)果,如銅離子濃度的增大,能耗明顯上升,但此方法處理含銅廢水的成本較大。實(shí)驗(yàn)同時(shí)測(cè)定了電驅(qū)動(dòng)膜在處理反滲透濃水方面的應(yīng)用,得出的結(jié)論為該方法能量消耗低,每噸水運(yùn)行電耗僅為2 kWh,且回收率高,系統(tǒng)回收率為75%,該處理過(guò)程無(wú)需換熱裝置,電膜產(chǎn)水可直接進(jìn)RO,按山東地區(qū)年平均水溫15°C加熱至25°C計(jì)算,每噸水加熱需蒸汽費(fèi)用約3元,因此該方法減少蒸汽消耗,節(jié)省費(fèi)用。電驅(qū)動(dòng)膜技術(shù)作為一種高科技手段,以其節(jié)能高效、無(wú)三廢產(chǎn)生、節(jié)約占地等優(yōu)點(diǎn)必將越來(lái)越廣泛地應(yīng)用于精細(xì)化學(xué)工業(yè),食品和醫(yī)療領(lǐng)域的特種分離,為產(chǎn)品的分離提純發(fā)揮越來(lái)越大的作用。
[Abstract]:Electrodrive membrane technology is one of the membrane separation technologies developed earlier and widely used in industry. In this paper, the treatment of high salt wastewater and heavy metal wastewater by electrodrive membrane technology is put forward. The purpose of this paper is to solve the problem of high salt wastewater and heavy metal wastewater treatment. The electrodrive membrane method is based on its working principle. This method is suitable for the treatment of these two kinds of wastewater. The advantage of this method is that it can be discharged up to standard after treatment, but the disadvantage is that the concentrated water needs further treatment. In this paper, simulated sodium bromide is used to represent high salt wastewater and copper ion is used to represent heavy metal wastewater. The main operating parameters, such as membrane voltage, current density, concentration change and energy consumption, are studied in this paper. The effect of different parameters on the treatment effect was studied. The results of electrodrive membrane study show that when the concentration of sodium bromide is about 15 000 mg / L, the concentration of sodium bromide can be reduced to 115 mg / L after treatment, and the salinity of the water is far below the discharge standard. This process can be used to remove sodium bromide. The results of electrodrive membrane study on heavy metal wastewater show that when the concentration of copper ion stays at about 150mg/L, the energy consumption and treatment efficiency reach the optimum results, such as the increase of copper ion concentration, the increase of energy consumption, However, the cost of treating copper-containing wastewater by this method is high. At the same time, the application of electric drive membrane in the treatment of reverse osmosis concentrated water was determined. The conclusion is that the energy consumption of this method is low, the electricity consumption per ton of water is only 2 kWhs, and the recovery rate is high, and the system recovery rate is 75%. The electric membrane can produce water directly into RO.The annual average water temperature of Shandong Province is 15 擄C to 25 擄C. the steam cost per ton of water heating is about 3 yuan, so the steam consumption is reduced and the cost is saved by this method. As a kind of high-tech means, electrodrive membrane technology will be more and more widely used in the separation of fine chemical industry, food and medical field, because of its advantages of energy saving and high efficiency, no waste generation, saving of land, etc. For the separation and purification of products play a more and more important role.
