Description
Technical field
This utility model belongs to hazardous waste processing technology field, is specifically related to a kind of high concentration waste emulsified mixture processing means.
Background technology
Emulsion mainly contains machine oil and surfactant, emulsifying agent is added formulated with oil emulsion dilute with water as required, emulsion is after repeatedly Reusability, becoming sour in various degree can occur, performance reduces, regularly replace new emulsion, so just creating a large amount of waste emulsified mixture, it is characterized in various in style, CODcr and oil content concentration are high, intractability is big, waste emulsified mixture is in addition to having the harm of general oily waste water, effect due to surfactant, machinery oil is highly dispersed in water, animals and plants, aquatile is more easy to absorb, and biology is also harmful to by surfactant itself, some water-fast noxious substances also can be made to be dissolved, therefore, process to waste emulsified mixture is the most very urgent.
Conventional waste emulsified mixture processing method includes: acidization, salting out method, membrane filter method, chemical oxidization method, heating etc..Different breaking methods is respectively arranged with pluses and minuses, but the restricted application of breaking method, and fixing method is difficult to adapt to different types of waste emulsified mixture, and for the process of same type waste emulsified mixture, it tends to be difficult to adapting to the change of water quality, treatment effect is unstable.The conventional materialization breaking method response time is long, and very flexible needs to add substantial amounts of medicament, and the sludge quantity of generation is very big, easily causes secondary pollution.Salting out method is swift in response, and the breakdown of emulsion time is short, but the most single medicament cannot breakdown of emulsion, need polytype salt compound, this adds increased screening medicament difficulty；Membrane filter method breakdown of emulsion applied range, but demulsification is undesirable, and the requirement to pretreatment is the highest, and it is stifled serious to there is film dirt, the problems such as the Membrane cleaning cycle is short, and above-mentioned each processing method is only applicable to process a certain waste emulsified mixture；But in actual process, the kind usually containing emulsion is more, and complicated component, such as: emulsifying liquid waste water, electroplating wastewater, percolate etc., use single method cannot realize focusing on, and be unable to reach preferable breakdown of emulsion and the effect of degraded CODcr.
Conclude waste emulsified mixture and process the difficult problem that faced, mainly include following some: first, waste emulsified mixture is difficult to process, and environmental hazard is big；Second, for different types of waste emulsified mixture, the treatment effect difference of various breaking methods is very big, and screening suitable breaking method wastes time and energy；3rd, waste emulsified mixture breakdown of emulsion operating cost is the highest, complex process, and chemical agent can increase the ion concentration in waste emulsified mixture.4th, either chemical agent breakdown of emulsion or heating demulsification type, all can destroy component and the character of waste oil, reduce the value of waste oil after breakdown of emulsion.
Chinese patent literature CN 104649481 A discloses a kind of equipment for processing waste emulsified mixture, comprising: except oil slick device, for carrying out pending waste emulsified mixture except oil slick processes, remove and float on the oil slick on waste emulsified mixture liquid level；Oily-water seperating equipment, for the waste emulsified mixture eliminating oil slick carries out oil-water separation process, removes the dispersed oil being suspended in waste emulsified mixture；Apparatus for electrochemical treatment, the waste emulsified mixture after processing oil-water separation carries out electrochemical treatments so that it is in oil emulsion and dissolved oil flocculation, obtain eliminating oil slick, dispersed oil and its oil emulsion and bulk processing waste emulsified mixture that dissolved oil has been flocculated；Wherein, the aluminium sheet and the nano ceramics film that use the power on carry out described electrochemical treatments；Wherein, utilize the nano ceramics film of power-off that bulk processing emulsion after staticly settling process is carried out hyperfiltration treatment, obtain the clear water without oil slick, dispersed oil, oil emulsion and dissolved oil.This device is by after electrochemical treatments, alumen ustum precipitation is generated after aluminum hydroxide precipitation generation coagulation that oil emulsion in waste water and dissolved oil produce with anode, aggregation, become SS class material to be flocculated, can be by further filtering removal, but but there is oil emulsion and dissolved oil component and character is destroyed, reduce the value of waste oil, additionally it uses nano ceramics film to retain the pollutant after flocculation, although can be with the oily substance after traps flocculated, but it is stifled serious to there is also film dirt, the problems such as the Membrane cleaning cycle is short.
