【摘要】：由于采用了與傳統(tǒng)造紙行業(yè)類(lèi)似的抄造成形技術(shù),每生產(chǎn)1噸造紙法再造煙葉產(chǎn)品約產(chǎn)生30～60噸廢水。造紙法再造煙葉生產(chǎn)廢水排放量大、成分復(fù)雜、色度高、化學(xué)需氧量高、纖維懸浮物多、濃度波動(dòng)較大,屬于難處理的高濃度有機(jī)廢水。開(kāi)展造紙法再造煙葉RO濃水的混凝處理研究有實(shí)際意義。本文以高鐵酸鉀(PF)和活性炭(AC)制備了含鐵活性炭(PF-AC),其鐵成分主要起氧化和絮凝作用,活性炭成分起吸附和催化作用的同時(shí)還是絮體形成和長(zhǎng)大的骨架。以聚合硫酸鐵(PFS)、陽(yáng)離子型聚丙烯酰胺(CPAM)、高鐵酸鉀(PF)、活性炭(AC)、含鐵活性炭(PF-AC)為混凝劑,開(kāi)展RO濃水混凝處理研究,繪制了 RO濃水的混凝處理出水水質(zhì)關(guān)于PFS投藥量、CPAM投藥量和pH三因素的響應(yīng)曲面,計(jì)算了 PFS-CPAM-pH對(duì)RO濃水的混凝處理出水水質(zhì)的擬合方程,確定了 PFS、CPAM和pH混凝處理RO濃水的最佳條件,研究了 PF、AC和PF-AC對(duì)經(jīng)PFS-CPAM處理后的RO濃水的后續(xù)處理效果,最后采用PFS、PF-AC和CPAM“混凝-氧化-吸附”處理RO濃水并優(yōu)化了處理過(guò)程。實(shí)驗(yàn)結(jié)果表明,以3000～3500 mg.L~(-1)PFS、1500～2500mg.L~(-1)PF-AC 和 1000μL.L~(-1)CPAM 處理色度 975 倍、COD 404.96 mg·L~(-1)、pH 7.56 和電導(dǎo)率 6.21 mS.cm~(-1) 的 RO 濃水,出水色度、COD、pH和電導(dǎo)率分別為16～29倍、30.83～47.78 mg·L~(-1)、6.91～7.15和6.77～6.86 mS·cm~(-1),達(dá)到《城鎮(zhèn)污水處理廠(chǎng)污染物排放標(biāo)準(zhǔn)(GB 18918-2002)》一級(jí)A標(biāo)準(zhǔn)要求。
[Abstract]:Because of the use of the same technology as the traditional papermaking industry, about 300.60 tons of waste water is produced for each ton of reconstituted tobacco products produced by paper-making process. The wastewater from reconstituted tobacco leaves produced by paper-making process is a kind of high concentration organic wastewater with high discharge, complex composition, high chroma, high chemical oxygen demand, more fiber suspensions and large fluctuation of concentration. It is of practical significance to study the coagulation treatment of RO concentrated water from tobacco leaf by paper-making process. In this paper, ferric activated carbon (PF-AC) was prepared from potassium ferrate (PFF) and activated carbon (AC). Its iron composition mainly oxidizes and flocculates, and activated carbon plays an important role in adsorption and catalysis, at the same time, it is the skeleton of flocs formation and growth. The study on RO concentrated water coagulation treatment was carried out with PFSN, CPAMN, potassium ferrate (PFN), activated carbon (AAC) and ferric activated carbon (PF-ACAC) as coagulants. In this paper, the response surface of the effluent quality of RO concentrated water for PFS dosage and pH was drawn, and the fitting equation of PFS-CPAM-pH to the effluent quality of RO concentrated water was calculated. The optimal conditions for the treatment of RO concentrated water by PFS- CPAM and pH coagulation were determined. The following treatment effect of PFS-CPAM treated RO concentrated water was studied. Finally, the treatment process of RO concentrated water was optimized by using PFS- PF-AC and CPAM "Coagulation-Oxidation-adsorption". The experimental results showed that the RO concentrated water was treated with PF-AC and 1000 渭 L.L~(-1)CPAM. The pH value was 7.56 and the conductivity was 6.21 mg 路cm ~ (-1) 路L ~ (-1) 路L ~ (-1) 路L ~ (-1) 路L ~ (-1) 路L ~ (-1) PF-AC and ~ (1000 渭 L.L~(-1)CPAM), respectively, for the treatment of RO concentrated water with a pH value of 404.96 mg / L ~ (-1) and a conductivity of 6.21 mg 路L ~ (-1). The pH and electrical conductivity of the effluent were 16.829 times and 47.78 mg / L ~ (-1), respectively, 6.91mg / L ~ (-1) and 6.77 ~ 6.86mS / cm ~ (-1) ~ (-1) respectively, which met the requirements of the first class A standard (GB 18918-2002) for the discharge of pollutants from municipal wastewater treatment plants.
