Along with the development of China's economic society, the dependence of oil is inevitably increased.Owing to Oil spills easily causes the pollution to surrounding soil in the process such as oil exploitation, transport, additionally the discharge of oily waste water also result in a series of soil with serious petroleum pollution problem.Petroleum pollution enters and local ecosystem, plant and health can be brought and be had a strong impact on after soil, as destroyed ecosystem stability, affect the absorption of Plant To Nutrient material, some highly toxic petroleum hydrocarbon compounds are accumulated in food chain and health are worked the mischief.Therefore soil with serious petroleum pollution problem has caused the extensive concern of various circles of society, and corresponding soil restoring technology is always up the focus of Recent study.Current administering method mainly includes Physical, bioanalysis and chemical method.In numerous soil restoring technology, surfactant potentiation eluting (SurfactantEnhancedWashing, SEW) technology is high, simple to operate because of its removal efficiency, it is believed that be the soil with serious petroleum pollution recovery technique of most prospect at present.Cleaning fluid composition used includes the moon, nonionic surfactant, auxiliary agent and water, petroleum hydrocarbon contaminant in soil is transferred to and is reached soil remediation purpose in cleanout fluid by the solubilization mainly utilizing surfactant in soil cleaning process, wherein auxiliary agent may advantageously facilitate the dissolution of organic contaminants in soil, improves the eluting effect of surfactant.If but the oil-containing cleanout fluid after eluting is directly discarded, not only cause the waste of medicament, increase rehabilitation cost, and environment can be caused secondary pollution.Therefore, develop a kind of method purifying oil-containing cleanout fluid, it is achieved recycling of cleaning agent, there is significant economic benefit and important environmental benefit.
The method processing oily waste water at present mainly has solvent extraction, ultrafiltration, photochemical treatment and absorption method etc..Research shows, absorption method is capable of the efficient removal to oily waste water, and absorption method most critical part is in that the screening of adsorbent.Natural organic adsorbent corn cob material (after broken for corncob processing, is made through strict screening；Main component: cellulose, hemicellulose, lignin etc.) owing to having loose structure, and C in glucose basic ring in cellulosic molecule6Primary hydroxyl group on position and C2、C3On secondary hydroxyl group and lignin structure in exist aromatic radical, methoxyl group, carbonyl, alcoholic extract hydroxyl group, phenolic hydroxyl group, carboxyl isoreactivity group, the quantity of the reaction increase adsorption functional group such as oxidation, esterification, etherificate and then raising absorbability can be passed through.
The present invention is using corn cob as raw material, after it is carried out pretreatment, it is modifiied by recycling anion surfactant further, for removing the petroleum pollution in oil-containing cleanout fluid (containing the moon, nonionic surfactant, auxiliary agent and petroleum pollution), it is achieved the regeneration of cleanout fluid.
Summary of the invention
It is desirable to provide a kind of method utilizing modified corn core adsorbent to purify eluting soil with serious petroleum pollution cleanout fluid, namely corn cob is carried out pretreatment and anion surfactant modifiies, become the adsorbent of function admirable, in order to purify the cleanout fluid after eluting soil with serious petroleum pollution, it is achieved the regeneration of cleanout fluid.
Technical scheme:
A kind of method utilizing modified corn core to purify eluting soil with serious petroleum pollution cleanout fluid, step is as follows:
1) pretreatment of corn cob powder
Corn cob is made the corn cob powder of 80-100 order through washing, crushed after being dried, it is added in sodium hydroxide solution or sulfuric acid solution, at room temperature magnetic agitation 1-3h, it is 6-7 that corn cob powder is washed to after filtration washing liquid pH, then dry for standby at 50-100 DEG C；
2) anion surfactant is utilized to prepare modified corn core adsorbent
Corn cob powder after above-mentioned pretreatment is added in aqueous solution of anionic surfactant, stirs, then ultrasonic Treatment 5-15min, the powder washing that will obtain after solid-liquid separation, dry at 90-110 DEG C afterwards, obtain modified corn core adsorbent；
3) oil-containing cleanout fluid purifies
Above-mentioned modified corn core adsorbent addition was processed in the cleanout fluid of soil with serious petroleum pollution, after mix homogeneously at 20-50 DEG C heating in water bath, and pass into the air that flow is 10-100mL/min and carry out stripping, solid-liquid separation is carried out after magnetic agitation 20-60min, namely the cleanout fluid after being purified by supernatant is used for cleaning soil with serious petroleum pollution again, according to the cleaning efficiency of oil in contaminated soil, evaluating the corn cob adsorbent purification efficiency to oil-containing cleanout fluid；Collecting attached oil corn cob adsorbent is specifying place to carry out burning disposal.
Described step 1) in the concentration of sodium hydroxide solution be 0.4-0.7mol/L, the concentration of sulfuric acid solution is 2.5-4mol/L；The amount ratio of corn cob powder and sodium hydroxide solution or sulfuric acid solution is 0.04-0.5g/mL.
Described step 2) in anion surfactant be dodecylbenzene sodium sulfonate (LinearAlkylbenzeneSulfonate, LAS) or sodium lauryl sulphate (SodiumDodecylSulfate, SDS)；The amount ratio of corn cob powder and anionic surfactant solution is 0.02-0.3g/mL.
Described step 3) in the amount ratio of modified corn core adsorbent and oil-containing cleanout fluid be 0.002-0.02g/mL.
It is an advantage of the current invention that:
The method is being removed in oil-containing cleanout fluid while unrecovered oil hydrocarbon, realize to anion surfactant in cleanout fluid, nonionic surfactant again with, cost cloudy, nonionic surfactant water-soluble liquid eluting soil with serious petroleum pollution is utilized thus significantly reducing, also eliminate the secondary pollution because cleanout fluid remaining petroleum hydrocarbon causes, the corn cob adsorbent of attached oil can carry out burning harmless treatment in appointment place, so method has significant economic benefit and environmental benefit.
