Description
Technical field
The present invention relates to a kind of sewage-treatment plant and method thereof, specifically ship sewage treatment dress
Put and method.
Background technology
Ship sewage treatment is an important content in vessel pollution control field, oil-containing in vessel oily water
Polytype oil, its source includes: lubricating oil, steam cylinder oil and hydraulic oil, cleaning agent, foaming agent (AFFF),
Paint and solvent etc..In vessel oily water a part oil in water in emulsified state, it is difficult to separate.If
These vessel oily waters do not do and effectively process and directly discharge, and can cause the pollution of ocean and river environment.
The decomposition of oils can produce the noxious substance such as benzopyrene and other polycyclic aromatic hydrocarbon, the on the one hand meeting of these catabolites
Be there is direct toxic action in biology;On the other hand, when the water containing micro oil is used for cultivating or irrigating, quilt
Bio-absorbable and be enriched with, by food chain enter human body, be detrimental to health.IMO data shows, the world
Cabin bilge oil-polluted water amount discharged every year by average single ship is the 1/10 of this ship gross tonnage, it has been found that illegal row
The oil content of the cabin biloge water gone out is up to 50000ppm.There is up to ten million ton oils the most every year by each
Kind of approach enters water body, and oil can form monolayer oil film and cover the water surface, makes water body and air exclusion and anoxia,
Produce stench, affect aquatile growth even dead.Within 2004, IMO makes rule in MEPC107. (49)
Fixed, instead of old MEPC60. (33) pact, add in new execution standard containing oil emulsion " C "
The test requirements document of liquid, therefore the effective technology processing vessel oily water of exploitation is significant.
The processing method of the vessel sewage of research, mainly has Physical, physical-chemical process, life the most at present
Thing chemical method, electrochemical process, chemical demulsification method and advanced oxidation processes.Various methods have certain applicable bar
Part and pluses and minuses.Bioanalysis, owing to being limited by the cultivation of microorganism and growth conditions, is transported at actual boats and ships
Row operating process can produce various problems.Therefore, for having the biology of preferable treatment effect containing sewage
Processing method should not use.Use membrane technology oil-polluted water to be processed, in external boats and ships the most
Application, and studies in China and application are the most less.It addition, for ship sewage treatment effect that reuse can be reached
Really, the rarest research of domestic and international this respect.In order to process for biloge water in time on boats and ships,
If biloge water can reach the water quality requirement of reuse after certain process, it is achieved " zero-emission simultaneously
Put ", so can not only save the volume of sewage storage cabinet in boats and ships, reduce consumption of raw materials, also achieve
Being continuing with after the recycling of oils resource and sewage disposal, the reuse of sewage can be substantially reduced supply
Demand, reaches the purpose of energy-saving and emission-reduction.
Oil and water can form emulsion under certain condition, and this emulsion in most cases presents oil-in-water
(O/W) or the form of Water-In-Oil (W/O), there is relative stability under certain condition.Ultrasonic dehydration
Have low cost, effective, do not produce the outstanding advantages such as secondary pollution.Ultrasonic emulsion breaking utilizes ul-trasonic irradiation
The displacement effect produced in the fluid media (medium) that character is different realizes oil-water separation.Owing to ultrasound wave is at You Heshui
In be respectively provided with good conductivity, so ultrasonic dehydration is applicable to various types of emulsion.Ultrasound wave
Breakdown of emulsion can reduce the temperature of breakdown of emulsion, the most just thus can reduce heating set with breakdown of emulsion
Standby and energy consumption, can also cancel the high-tension electricity dehydration equipment of complexity simultaneously.Ultrasound wave and demulsifier have good
Synergism, it can improve the functioning efficiency of demulsifier, reduce the consumption of demulsifier.Ultrasound wave and chemistry
Demulsifier combines has good development prospect for emulsification crude oil demulsification dehydration, particularly to those with conventional
Dewatering type is difficult to the crude oil emulsion breaking emulsion and dewatering proved effective.
Kynoar PVDF ultrafiltration membrane is the macromolecular material of a kind of function admirable, steady with the chemistry that it is good
Qualitative, radiation resistance and thermostability, mechanical strength are big, high tenacity, antiacid caustic corrosion, preparation technology are simple,
The plurality of advantages such as cost is relatively low, apply widely in fields such as waste water process and reuses.But due to tool itself
Have strong-hydrophobicity, surface energy is low, wettability is poor, particularly applies in aqueous phase system separation process, is passing
Making flux depression due to Adsorption of solute and Pore Blocking during matter, separation process needs bigger driving
Power, in separation process, membrane flux and two main Separation Indexes of interception capacity constantly decline, and clean very
Difficulty, shortens the service life of film.In order to decelerating membrane pollution, film surface can be carried out hydrophilic modifying,
Pollutant are made to be difficult to deposit on the surface of the film and just can make the pollution on film surface under less effect power
Thing is removed.Along with the hydrophilic improvement of pvdf membrane, permeability of the membrane, resistance tocrocking and stability are the most available
Preferably improving, the overall performance of film is promoted, and has significantly expanded its range of application.Modification for film
Being divided into two big classes one is film matrix modification, and including being blended, copolymerization process, another kind is membrane surface modification.
Photoelectro-catalytic oxidation technology is a kind of high-level oxidation technology, has equipment simple, easily controllable, and
The advantages such as secondary pollution will not be brought, be described as the water technology of " environmental friendliness ".Photoelectrocatalysioxidization oxidization
Technology is the technology of a kind of oil-polluted water of can effectively degrading, and the speed of photoelectrocatalysioxidization oxidization degradation of organic substances is bright
The aobvious independent role speed sum higher than photochemical catalytic oxidation with electrocatalysis oxidation reaction, thus light and electric process tool
There is significant synergism.TiO2 is one of catalysis material the most of greatest concern, but applies in reality
In there is the problem that electron-hole pair recombination rate is high.TiO2 nanotube have even structure, high-sequential,
Specific surface area is big, stable chemical nature and advantage, precious metals pt and SnO2 and TiO2 such as reusable receive
Mitron can reduce electron-hole pair recombination rate after mixing, improves photocatalysis efficiency.
