【摘要】：酒糟和污泥是工業(yè)廢棄物之一。酒糟為釀酒工業(yè)廢棄物,污泥為污水廠的沉淀物經(jīng)脫水而成的。酒糟以飼料資源化為主,而污泥多以填埋處置為主,不能有效的治理其二次污染的問(wèn)題,如何對(duì)其兩者進(jìn)行綜合利用,實(shí)現(xiàn)其處理的資源化與合理化,改善周圍的環(huán)境,防止對(duì)周圍環(huán)境造成污染具有重要的意義。酒糟、污泥混合后可實(shí)現(xiàn)其理化性質(zhì)互補(bǔ)協(xié)同效果,將酒糟與污泥均勻混合,酒糟因此變得緊實(shí)。將酒糟-污泥作為碳濃縮吸附劑合成的原料,在不同反應(yīng)溫度條件下制備碳濃縮吸附劑。旨在考察不同炭化溫度和不同酒糟與污泥比例條件下制備碳濃縮吸附劑的表征,選擇出對(duì)氨氮、磷和重金屬鉻的最佳制備及其吸附條件。碳濃縮吸附劑制備與表征研究結(jié)果顯示：400℃～500℃的條件下制備的碳濃縮吸附劑產(chǎn)率較低；而在600℃～700℃范圍內(nèi)炭化產(chǎn)生的碳濃縮吸附劑的性質(zhì)和結(jié)構(gòu)相對(duì)穩(wěn)定。不同碳濃縮吸附劑的pH值總體表現(xiàn)為700℃600℃500℃400℃,pH從7.4增加到10.1,即多數(shù)碳濃縮吸附劑為堿性。揮發(fā)性有機(jī)物含量隨炭化溫度升高亦呈增加趨勢(shì)。FT-IR分析結(jié)果顯示：碳濃縮吸附劑富含大量的芳香族建,低溫下制備的碳濃縮吸附劑還含有飽和的烴基和長(zhǎng)鏈烴基。隨反應(yīng)溫度增加,碳濃縮吸附劑中脂肪性烷基鏈基本消失,而芳香性逐漸變多。SEM分析結(jié)果顯示：隨著炭化溫度升高碳濃縮吸附劑從盲孔數(shù)目減少到表面空穴增多,形成堆疊狀態(tài),并且堆疊狀態(tài)物質(zhì)表面較粗糙。碳濃縮吸附劑吸附氮廢水實(shí)驗(yàn)結(jié)果顯示：反應(yīng)溫度400℃～700℃之間時(shí),酒糟：污泥為20：80時(shí)制取的碳濃縮吸附劑的吸附性能最佳,其對(duì)氨氮的去除率分別為71.9%、82.8%、83.9%和81.1%。對(duì)含磷廢水吸附研究結(jié)果顯示：炭化溫度400℃～700℃范圍內(nèi)吸附含磷廢水時(shí)最佳比例為酒糟：污泥為0：100(污泥占生物質(zhì)含量100%),400℃的碳濃縮吸附劑對(duì)廢水中磷呈解吸狀態(tài)、500℃～700℃碳濃縮吸附劑對(duì)廢水磷的去除率分別為35.7%、53.1%、68.5%。對(duì)含Cr(Ⅵ)廢水吸附研究結(jié)果顯示：吸附重金屬鉻廢水時(shí)最佳比例為酒糟：污泥為90：10,炭化溫度400℃～700℃的碳濃縮吸附劑對(duì)Cr6+的去除率分別為87.9%、91.5%、94%和99.1%。采用碳濃縮吸附劑對(duì)副品紅廢水進(jìn)行吸附,吸附最佳時(shí)間為150min,吸附過(guò)程中溫度和pH對(duì)其影響不明顯,最佳的碳濃縮吸附劑的添加量為10g/300mL,采用兩級(jí)或者多級(jí)吸附的方式能夠減少吸附劑的使用量。鐵屑-碳濃縮吸附劑偶聯(lián)反應(yīng)過(guò)程中最適的反應(yīng)條件是pH 3±0.1,鐵屑的最適加入量10g/300mL,鐵屑與碳濃縮吸附劑的質(zhì)量比1：1,反應(yīng)時(shí)間40 min,反應(yīng)溫度對(duì)鐵屑.碳濃縮吸附劑偶聯(lián)反應(yīng)影響不明顯。在雙氧水參與的鐵屑-碳濃縮吸附劑偶聯(lián)反應(yīng)過(guò)程中,最佳的反應(yīng)條件為pH4±0.1,雙氧水的最適加入量35 mmoL,反應(yīng)時(shí)間30 min,反應(yīng)過(guò)程與溫度的關(guān)系不明顯。碳濃縮吸附劑再生實(shí)驗(yàn)過(guò)程中,再生溫度為700℃,程升溫度為40℃,再生時(shí)間為40 min,再生次數(shù)為3-4次為最佳再生條件,氮?dú)饬魉賹?duì)再生效果幾乎無(wú)影響。
[Abstract]:Lees and sludge is one of the industrial waste lees. For the brewing of industrial waste, sewage sludge sediment is formed by dehydration. The lees feed resources mainly, and sludge to landfill disposal, not effective governance of secondary pollution, how to carry out the comprehensive utilization of two, to achieve its processing resources and rationalization, improve the surrounding environment, which is of great significance to prevent pollution of the surrounding environment. Lees, the mixed sludge can achieve the physicochemical properties of complementary and synergistic effect, the lees and sludge mixed evenly, thus became more compact. The lees lees and sludge as carbon adsorbent concentration synthetic material, preparation carbon concentration of adsorbent under different temperature conditions. In order to prepare carbon adsorption characterization of thickening agent under different carbonization temperature and different lees and sludge ratio conditions, selection of nitrogen, phosphorus and heavy The best preparation and adsorption conditions of metallic chromium. Carbon concentrating adsorbent preparation and characterization of the study shows: 400 to 500 DEG C under the condition of preparation of carbon adsorbent concentration yield is low; the structure and properties of carbon concentration of adsorbent and carbonization at 600 to 700 DEG C range is relatively stable. Different carbon adsorbent concentration pH value of the overall performance of 700 C 600 C 500 C 400 C, pH increased from 7.4 to 10.1, the most concentrated carbon adsorbent is alkaline. Volatile organic content also increased the.FT-IR analysis results showed that with the carbonization temperature, carbon concentration of adsorbent is rich in aromatic large building under low temperature, preparation of carbon adsorbent concentration also contains saturated hydrocarbon and long chain alkyl. With the reaction temperature increased, the adsorption of carbon enriched fatty alkyl chain agent disappeared, and the aromaticity becomes multi.SEM analysis results show that with the temperature rising High concentration carbon adsorbent from surface to reduce the number of blind hole increased to form a stack, and the stack state material with rough surface. The adsorption of nitrogen enriched carbon wastewater experiment results show that: the reaction temperature is 400 DEG C to 700 DEG C, lees: sludge is 20:80 carbon adsorbent for the adsorption of concentrated performance is best. The 82.8% of the ammonia nitrogen removal rate were 71.9%, 83.9%, and 81.1%. of wastewater containing phosphorus adsorption results showed that the carbonization temperature 400 to 700 DEG C within the adsorption of phosphorus containing wastewater when the best proportion was: 0:100 (sludge lees sludge biomass accounted for 100%, 400 C content) carbon concentration adsorbent for wastewater phosphorus is desorption state, 500 to 700 DEG C carbon concentration adsorbent for wastewater phosphorus removal rates were 35.7%, 53.1%, 68.5%. of Cr (VI) wastewater adsorption results showed that the adsorption of heavy metal chromium wastewater is the best proportion For the lees: sludge as 90:10, carbonization temperature 400 to 700 DEG C carbon adsorbent concentration on the removal rate of Cr6+ were 87.9%, 91.5%, 94% and 99.1%. using carbon adsorbent for concentrated Parafuchsin wastewater by adsorption, the best time for adsorption of 150min, temperature and pH on adsorption process of its influence is not obvious amount of carbon concentration the best adsorbent for 10g/300mL, using two or more stages of adsorption can reduce the amount of adsorbent used. Iron - carbon adsorption concentration and the best reaction conditions of agent coupling reaction in the process of the pH 3 + 0.1, the optimum amount of 10g/ iron 300mL, iron and carbon concentration of adsorbent the mass ratio of 1:1, reaction time is 40 min, the reaction temperature of the iron. Influence of adsorbent carbon concentration is not obvious. In the coupling reaction of H2O2 in iron - carbon concentration and adsorbent coupling reaction, the optimum reaction conditions for pH4 + 0.1, the hydrogen peroxide water Suitable amount of 35 mmoL, the reaction time is 30 min, the relationship between reaction temperature and carbon concentration is not obvious. The adsorbent regeneration process, regeneration temperature is 700 DEG C, Cheng l temperature is 40 DEG C, the regeneration time is 40 min, the number of regeneration is 3-4 times for the best regeneration conditions, nitrogen flow rate has little effect on the the regeneration effect.
