【摘要】：進入二十一世紀,伴隨著我國工業(yè)化水平的提高,酚污染事件更是屢見不鮮,給人民的生產(chǎn)生活帶來嚴重不便,對當(dāng)?shù)氐淖匀画h(huán)境造成了相當(dāng)?shù)钠茐�。除酚藥劑有哪�?這些藥劑的去除效果如何,在何種情況下選取哪種藥劑除酚較為經(jīng)濟,酚污染事件的發(fā)生對水廠的處理成本有何影響。這些都是需要研究考慮的問題。高鐵酸鉀、高錳酸鉀、粉末活性炭都是去除水中苯酚的常用藥劑。高錳酸鉀和粉末活性炭不僅自身都有一定的去除苯酚能力,而且兩種藥劑聯(lián)合使用時,可以起到協(xié)同去除苯酚的作用,且去除效果好于二者單獨使用效果的線性疊加。高鐵酸鉀作為新型多功能綠色環(huán)保水處理劑,其反應(yīng)原理與高錳酸鉀相似,但不會提高水的色度以及水中Mn2+的含量。在濃度較高苯酚污染情況下,高鐵酸鉀因其良好的去除效果,綠色環(huán)保的特點成為首選藥劑,具有廣闊的使用前景。 高鐵酸鉀聯(lián)合粉末活性炭去除苯酚沒有達到預(yù)想效果,可能是由于高鐵酸鉀的還原產(chǎn)物氫氧化鐵(Fe(OH)3)膠體沒有起到強化粉末活性炭吸附的作用。利用靜態(tài)試驗,自配模擬苯酚污水。首先單獨投加藥劑,考察每種藥劑的投加量,溶液溫度,pH,反應(yīng)時間等因素對去除效果的影響。其次考察給定環(huán)境條件下,高鐵酸鉀聯(lián)合粉末活性炭,高錳酸鉀聯(lián)合粉末活性炭去除苯酚時不同投加量組合情況下的去除效果。最后根據(jù)實驗結(jié)果結(jié)合市場分析,得出各種藥劑投加情況下的費用預(yù)算,最終給出最為經(jīng)濟的藥劑選擇。(1)配置0.21mg/L的苯酚溶液作為原液�？疾靻为毻都痈咤i酸鉀時投加量,溶液溫度,pH,反應(yīng)時間等因素對去除效果的影響。(2)配置相同原液。考察單獨投加高鐵酸鉀時投加量,溶液溫度,pH,反應(yīng)時間等因素對去除效果的影響。(3)配置相同原液�？疾靻为毻都臃勰┗钚蕴繒r投加量,溶液溫度,pH,反應(yīng)時間等因素對去除效果的影響。(4)配置相同原液�？疾烊芤涸�18℃,pH=7.2,給定反應(yīng)時間情況下高鐵酸鉀聯(lián)合投加粉末活性炭不同的藥劑投加量組合對去除效果的影響,并初步探討其去除機理,分析產(chǎn)生此組去除效果的原因。(5)配置相同原液。考察溶液在18℃,pH=7.2,給定反應(yīng)時間情況下高錳酸鉀聯(lián)合投加粉末活性炭不同的藥劑投加量組合對去除效果的影響,并初步探討其去除機理,分析產(chǎn)生此組去除效果的原因。主要結(jié)論為：(1)自然條件下(18℃,pH=7.2)苯酚污染物濃度為0.21 mg/L時,三種藥劑去除效果在以下投加量時達到最佳效果：高鐵酸鉀投加量8mg/L,可以到達到Ⅳ類地表水環(huán)境質(zhì)量標準；高錳酸鉀投加量3mg/L,可以到達到Ⅰ類地表水環(huán)境質(zhì)量標準；粉末活性炭投加量120mg/L,可以到達到V類地表水環(huán)境質(zhì)量標準。(2)自然條件下(18℃,pH=7.2)苯酚污染物濃度為0.21 mg/L時,高鐵酸鉀聯(lián)合粉末活性炭氧化絮凝吸附去除苯酚效果最好條件為：粉末活性炭投加量120mg/L,高鐵酸鉀投加量8mg/L,可以到達到Ⅳ類地表水環(huán)境質(zhì)量標準。(3)相同自然條件,污染溶度時,高錳酸鉀聯(lián)合粉末活性炭氧化絮凝吸附去除苯酚效果最好條件為：粉末活性炭投加量120mg/L,高錳酸鉀投加量1mg/L,可以到達到Ⅳ類地表水環(huán)境質(zhì)量標準。(4)相同自然條件,污染溶度時,當(dāng)高錳酸鉀投加量為0.8mg/L,粉末活性炭投加量30mg/L時,達到這兩種藥劑經(jīng)濟最優(yōu)組合,苯酚去除率為60.55%,每噸水增加藥劑費用0.614元,設(shè)備總投資費用76萬元,水廠設(shè)備年耗費58520元。(5)相同自然條件,污染溶度時,當(dāng)高鐵酸鉀投加量為lmg/L,粉末活性炭投加量30mg/L時,達到這兩種藥劑經(jīng)濟最優(yōu)組合,苯酚去除率為52.94%,每噸水增加藥劑費用0.626元,設(shè)備總投資費用76萬元,水廠設(shè)備年耗費58520元。(6)正常情況下,當(dāng)水廠正常運行出水即可達標時,一旦發(fā)生苯酚污染物突發(fā)性污染事件時,考慮到去除效果,經(jīng)濟,環(huán)保以及對后續(xù)處理的影響,選擇投加高鐵酸鉀作為處理藥劑較為合適。
[Abstract]:In twenty-first Century, with the improvement of the level of industrialization in China, the phenol pollution events were more common, which brought serious inconvenience to the people's production and life, and caused considerable damage to the local natural environment. The effects of the occurrence of phenol pollution events on the cost of treatment in water plants are all issues to be considered. Potassium ferrate, Potassium Permanganate, powdered activated carbon are commonly used to remove phenol in water. Both Potassium Permanganate and powdered activated carbon not only have a certain ability to remove phenol, but also when the two agents are used together. The effect of synergistic removal of phenol, and the removal efficiency is better than the linear superposition of the two individual use effect. As a new multifunctional green water treatment agent, potassium ferrate is similar to Potassium Permanganate, but it does not increase the color of water and the content of Mn2+ in water. Under the condition of high concentration phenol pollution, potassium ferrate Good removal effect, green environmental characteristics become the first choice agent, and has a broad application prospect. Potassium ferrate combined powder activated carbon removal of phenol did not achieve the desired effect. It is possible that the effect of potassium ferrate iron hydroxide (Fe (OH) 3) colloid has not played the role of strengthening the adsorption of powdered activated carbon. The effects of the dosage of each agent, the temperature of the solution, the pH and the reaction time on the removal efficiency were investigated by adding the simulated phenol wastewater. Secondly, the removal of potassium ferrate combined powder activated carbon and the combination of Potassium Permanganate combined powder activated carbon with different dosage combinations under given environment conditions was investigated. Finally, according to the experimental results combined with market analysis, the cost budget of all kinds of medicaments was obtained, and the most economical choice was given. (1) the phenol solution of 0.21mg/L was used as the original solution. The effects of adding amount, solution temperature, pH, reaction time and other factors on the removal efficiency were investigated. (2) configuration The effect of addition amount, solution temperature, pH, reaction time and other factors on the removal efficiency were investigated. (3) the effects of the same original liquid on the removal efficiency when the powder activated carbon was added separately, the solution temperature, pH, reaction time and other factors on the removal efficiency. (4) the same original liquid was configured, and the solution was at 18, pH=7.2, The effect of the combined dosage of potassium ferrate combined with powder activated charcoal on the removal effect of different dosage of powdered activated carbon under given reaction time was given, and its removal mechanism was preliminarily discussed. (5) configuration of the same original liquid. The combination of the solution at 18, pH=7.2, and the given reaction time of Potassium Permanganate combined with powder powder. The effect of the dosage combination of different agents on the removal efficiency of activated carbon was discussed and its removal mechanism was preliminarily discussed. The main conclusions were as follows: (1) when the concentration of phenol pollutants in natural conditions (18, pH=7.2) was 0.21 mg/L, the removal effect of the three chemicals reached the best effect when the dosage was added below: ferric acid Potassium dosage of 8mg/L can reach the environmental quality standard of type IV surface water, and the dosage of Potassium Permanganate is 3mg/L, which can reach the standard of surface water environmental quality of class I; the dosage 120mg/L of powdered activated carbon can reach the standard of V surface water environment quality. (2) when the concentration of phenol pollutants is 0.21 mg/L under natural conditions (18, pH=7.2), high The best conditions for the removal of phenol by the combination of potassium ferric acid and powdered activated carbon are as follows: the dosage of powdered activated carbon is 120mg/L, and the dosage of potassium ferrate is 8mg/L. (3) the effect of oxidation flocculation and flocculation of Potassium Permanganate combined powder activated carbon for removal of phenol in the same natural conditions and pollution solubility The best condition is: powder activated carbon dosage 120mg/L, Potassium Permanganate dosage 1mg/L, can reach the grade IV surface water environmental quality standard. (4) the same natural conditions, when the pollution solubility, when the amount of Potassium Permanganate adding 0.8mg/L, powder activated carbon dosage 30mg/L, to achieve the optimal combination of these two chemicals, the phenol removal rate of 60.55%, The cost per ton of water increased 0.614 yuan, the total investment cost of the equipment was 760 thousand yuan, the annual cost of the equipment of the water plant was 58520 yuan. (5) the same natural conditions, when the dosage of potassium ferrate was lmg/L and the powdered activated carbon was added 30mg/L, the optimal combination of the two chemicals was reached, the phenol removal rate was 52.94%, and the cost per ton of water increased 0.626. Yuan, the total investment cost of the equipment is 760 thousand yuan, and the equipment of the water plant is 58520 yuan a year. (6) under normal conditions, when the water plant can reach the standard when the water is running normally, it is more appropriate to choose potassium ferrate as the treatment agent in consideration of the effect of removal, economy, environmental protection and the effect on the subsequent treatment.
