【摘要】：本論文針對(duì)徐州某焦化廠遺留場(chǎng)地的多環(huán)芳烴污染情況,選取菲、芘作為目標(biāo)污染物,將烷基糖苷(APG)和十二烷基苯磺酸鈉(SDBS)按不同比例復(fù)配,考察其復(fù)配行為及對(duì)菲、芘的增溶洗脫效果,結(jié)果如下:(1)APG/SDBS復(fù)配體系的復(fù)配行為研究表明:C總一定時(shí),隨著復(fù)配比α增大,表面張力γ和臨界膠束濃度CMC表現(xiàn)出先降低后升高的趨勢(shì);當(dāng)α=0.4時(shí)復(fù)配體系的CMC最小(200mg/l),且當(dāng)α≤0.4時(shí),復(fù)配體系CMC均低于二者單一表面活性劑的CMC;當(dāng)α≤0.7時(shí),實(shí)際測(cè)得CMCexp值低于理想溶液混合的CMC*值,復(fù)配體系表現(xiàn)出較為明顯的增效作用;(2)APG/SDBS復(fù)配體系水溶液中菲、芘的增溶效果研究表明:當(dāng)復(fù)配體系的α一定時(shí),隨著C總的增加菲、芘的Sw和Sw/S*均增加。當(dāng)復(fù)配體系C總一定時(shí),隨著α增大,菲、芘的Sw和Sw/S*先升高后降低,α=0.4時(shí)得到最高值,α=1時(shí)得到最低值;復(fù)配體系對(duì)菲、芘的MSR在α=0.2,0.3,0.4時(shí)較高。當(dāng)復(fù)配體系C總和α一定時(shí),菲的Sw和MSR均大于芘,但是芘的Sw/S*遠(yuǎn)大于菲。環(huán)境溫度由10℃升至50℃,菲、芘的Sw逐漸升高,當(dāng)溫度高于30℃,增加趨勢(shì)變緩;體系p H由5升至10,菲、芘的Sw先增加后緩慢降低,在p H=9時(shí)最大(菲:33.83mg/l、芘:30.68mg/l)。(3)復(fù)配體系在不同濃度、復(fù)配比、固液比、溫度、p H及超聲條件下對(duì)土壤中菲、芘的洗脫率實(shí)驗(yàn)研究表明:復(fù)配體系濃度C總=4000mg/l時(shí),隨著α增大,對(duì)菲、芘的洗脫效率先升高后降低,在α=0.4時(shí)達(dá)到最高值,菲72.4%、芘61.05%,且洗脫效率明顯高于單一的SDBS和APG;α=0.4時(shí),隨著C總不斷增大,復(fù)配體系對(duì)菲、芘的洗脫效率逐漸升高。α=0.4,C總=4000mg/l時(shí),隨著p H升高,復(fù)配體系對(duì)菲、芘的洗脫效率先增加后降低,在p H為9左右達(dá)到最大值(菲:72.78%、芘:61.05%);表面活性劑溶液體積、溫度、超聲時(shí)間的增加,復(fù)配體系對(duì)菲、芘的洗脫效率增加;超聲時(shí)間的增加,復(fù)配體系對(duì)菲、芘的洗脫效率逐漸增大,且超聲顯著提高復(fù)配體系對(duì)菲、芘的洗脫效率,超聲時(shí)間為3h時(shí),菲、芘洗脫效率已從未超聲前的73.4%和61.2%增加至94.2%和91.4%。
[Abstract]:In this paper, we selected phenanthrene and pyrene as the target pollutant in the pollution of polycyclic aromatic hydrocarbons in a coking plant in Xuzhou. The compound behavior of alkyl glucoside (APG) and twelve alkyl benzene sulfonate (SDBS) were investigated in different proportions, and the solubilization and elution effects of phenanthrene and pyrene were investigated. The results were as follows: (1) the study table of the compound behavior of the (1) APG/SDBS compound system Ming: when C is always certain, with the increase of compound ratio alpha, the surface tension and the critical micelle concentration CMC show a tendency to decrease first and then increase. When alpha =0.4 is the minimum CMC (200mg/l) of the compound system, and when alpha < 0.4, the CMC of the compound system is lower than the CMC of the single surfactant of two. When the alpha is less than 0.7, the actual CMCexp value is lower than the ideal solution mixing. The CMC* value of the compound system showed a more obvious synergistic effect. (2) the study on the solubilization of phenanthrene and pyrene in the aqueous solution of the APG/SDBS compound system showed that when the alpha of the compound system was fixed, the Sw and Sw/S* of pyrene increased with the increase of the total C of phenanthrene and pyrene. When the compound system C was always certain, with the increase of alpha, the Sw and Sw/S* of phenanthrene and pyrene were raised first and then decreased, and the alpha =0.4 was reduced. When the maximum value is obtained, the lowest value is obtained at alpha =1, and the MSR of pyrene is higher at alpha =0.2,0.3,0.4. When the compound system C sum alpha is certain, the Sw and MSR of phenanthrene are larger than pyrene, but the Sw/S* of pyrene is larger than phenanthrene. The environmental temperature rises from 10 to 50, and the Sw of phenanthrene and pyrene gradually rises, when the temperature is higher than 30, the trend becomes slow; P H of the system is 5. To 10, the Sw of phenanthrene and pyrene increased slowly and then decreased slowly at P H=9 (phenanthrene: 33.83mg/l, pyrene: 30.68mg/l). (3) the experimental study on the elution rate of phenanthrene and pyrene in soil under the conditions of different concentration, compound ratio, solid-liquid ratio, temperature, P H and ultrasonic conditions showed that when the concentration of the compound system was total =4000mg/l, the elution efficiency to phenanthrene and pyrene with the increase of alpha was increased. First increase and then decrease, the highest value is reached at alpha =0.4, phenanthrene 72.4% and pyrene 61.05%, and the elution efficiency is obviously higher than that of single SDBS and APG. As C increases, the elution efficiency of phenanthrene and pyrene gradually increases with the increasing of C. When alpha =0.4, C total =4000mg/l, the elution efficiency of phenanthrene and pyrene in the compound system increases first and then decreases with the increase of P H, in P H. To reach the maximum value of 9 (phenanthrene: 72.78%, pyrene: 61.05%), the volume, temperature, and ultrasonic time of the surfactant increased, the elution efficiency of phenanthrene and pyrene increased, the ultrasonic time increased, the elution efficiency of phenanthrene and pyrene increased gradually, and the elution efficiency of the compound system to phenanthrene and pyrene was increased significantly by ultrasound, and the ultrasonic time was 3H The elution efficiency of phenanthrene and pyrene has increased from 73.4% and 61.2% before ultrasound to 94.2% and 91.4%. respectively.
