Abstract
The invention discloses an emulsion breaker. The emulsion breaker comprises the following components: an initiator, a surfactant, urea and water. The emulsion breaker has the advantages of high oil removal efficiency, no substance producing toxicity to microorganisms, good oil solubility, and capability of reducing the wall-hanging phenomenon of oil residues and blockage of pipelines, improving the mobility of the oil residues and aiding the recycling of waste oil. When the emulsion breaker is specifically used, less emulsion breaker is used, the reaction time is short, and byproducts have no adverse impact on the subsequent biochemical treatment.
Description
Technical field
The invention belongs to chemical field, relate to a kind of demulsifier.
Background technology
The high concentration that coal chemical industrial waste water is coal solidifying, produce in the trans-utilization of liquefaction, gasification containing organic matter, cyanogen, ammonia nitrogen,The pollutant industrial wastewaters such as heavy metal. Wherein organic pollution comprise oils, phenols, polycyclc aromatic compound and nitrogenous, oxygen,The heterocyclic compound of sulphur etc. Coal chemical industry enterprises waste discharge is taking high concentration gas washing wastewater as main, and in comprehensive wastewater, CODcr existsAbout 5000mg/l, ammonia nitrogen be at 200-500mg/l, total oil 200-400mg/L.
Along with the progress of Coal Chemical Industry industry constantly has new method and technology for the treatment of coal chemical industrial waste water, its technology respectively has excellentBad. So utilizing several different methods associated treatment coal chemical industrial waste water is the developing direction of Coal Chemical Engineering Industry wastewater processing technology. Anaerobism-Aerobic Combined Treatment coal chemical industrial waste water can obtain desirable treatment effect, and operational management and cost are relatively low, and this technique is coalWastewater from chemical industry mainly select technique. But come water concentration higher and while containing more hardly degraded organic substance water outlet be difficult to stably reaching standard.Therefore carrying out into water pretreatment oil removing is to solve the important channel that biochemical influent concentration is high, bio-toxicity is large, organic pollution load is large.In waste water, oils is divided into heavy oil, light oil, dissolved oil, emulsion, the conventional gravity oil removal of pretreatment at present, oil removal by air bubbling, absorptionExcept wet goods technique. The sewage that enters aerobic stage must be controlled total oil content amount lower than 50mg/L, preferably should be less than 20mg/L. ThusThe effect of visible oil removing directly determines the success or failure of coal chemical industrial waste water biochemical treatment.
Within open day, be on December 30th, 2015 Chinese patent CN105198040A Invention Announce one can be used for oil-in-water typeThe method that emulsifying waste water fast emulsion breaking purifies. The method is by making full use of the special boundary of high-effect water-oil separating material to oil and waterFace characteristic, reaches the object of fast emulsion breaking and water-oil separating, can be used for oil-in-water type emulsus waste water to carry out breakdown of emulsion purification. RightThere is the feature such as Water-In-Oil, oil-in-water in oil emulsion, dispersed oil in coal chemical industrial waste water, and this demulsifier stress efficacy is single, difficult fullFoot Coal Chemical Industry processing requirements.
Within open day, be a kind of crude Treatment demulsifier of Chinese patent CN105176575A disclosure of the invention on December 23rd, 2015,Formula is: 2184,25 parts of polyethers demulsifiers; 2189,25 parts of polyethers demulsifiers; 10-15 parts of methyl alcohol or absolute ethyl alcohols;35-40 parts, water. This demulsifier is applicable to contain the operating mode that concentration is higher, has obvious difference compared with coal chemical industrial waste water oil-containing feature,And contain organic solvent micro-follow-up biochemical treatment is had to impact.
The Chinese patent CN105174552A invention that open day is on December 23rd, 2015 relates to a kind of Coal Chemical Industry high-concentration sewageOil removal treatment method; Its concrete steps are as follows: high Coal Chemical Industry strong sewage is entered to oil removing breakdown of emulsion unit and add demulsifier and help solidifyingAgent, makes the oily substance breakdown of emulsion in waste water reach removal effect; Then the waste water after oil removing breakdown of emulsion is entered to absorbing unit, pass throughAdsorbent is further removed solid suspended particle and the oily substance in waste water. It is more that this processing method adds pharmaceutical quantities, needs againAdd adsorbent, complex disposal process, is unfavorable for large-scale promotion utilization.
The Chinese patent CN105107235A that open day is on December 2nd, 2015 the invention discloses a kind of for oil-in-water breastDemulsifier that liquid system separates and preparation method thereof and application. Described method comprises the steps: 1) shitosan and acid are mixed,Obtain chitosan solution; 2) PMAm and chitosan solution mixing are left standstill, obtain shitosan-PMAmHydrogel; 3) shitosan-PMAm hydrogel is carried out to frozen dried, obtain demulsifier. This demulsifier specific aim listOne, be not suitable for the oil-containing features of Coal Chemical Industry uniqueness, use in this regard scope wideless.
For processing coal chemical industrial waste water, above treatment process technology is single, is difficult to obtain desirable breaking milk and removing oil outlet effect,Therefore, a kind of reliable for coal chemical industrial waste water treatment technology, easy and simple to handle demulsifier of exploitation, solves Coal Chemical Industry oil removal treatment difficultyTopic, significant to Coal Chemical Industry industry sustainable and healthy development.
