Description

A kind for the treatment of unit containing endocrine disrupter pickling waste waters
Technical field
The utility model belongs to the environmental technology field of acid treatment waste liquid, and more specifically, for oceanographic engineering association pickle solution, contained endocrine disrupter is as a kind for the treatment of unit of persistent organism.
Background technology
Can be used for pickling waste waters process main method to be at present classified as follows:
Sulfuric acid washing waste water treatment process mainly contains the methods such as neutralisation, sulphate of iron method, organic extractant solution method, dialysis, ion exchange method.Three kinds of methods next are still in the experimental study stage.There are red iron oxide sulphur ammonium method, wetland method, biological process in addition.In recent years, waste water zero emission is day by day mentioned continually at industrial circle, also becomes the important indicator of every profession and trade in planning examination.Along with progress of research, abroad come into effect with the pickling waste waters of the art breading such as diffusion dialysis-diaphragm electrolysis, biosorption technology, micelle enhanced ultrafiltration method containing endocrine disrupter.
Main technique is introduced
(1) foam separation technique: foam separation is according to the principle of surface adsorption, and the bubble utilizing ventilation bubbling to be formed in the liquid phase is carrier, is separated, is therefore separated also known as steel foams the solute in liquid phase or particle.
Foam separating technology is one of new separation technology grown up the nearly more than ten years.Foam separation is the principle according to absorption, to containing surfactant liquid in aeration, the surfactant in liquid is made to be gathered on liquid-gas interface (surface of bubble), foam layer is formed above main body of liquid, foam layer and liquid phase main body are separated, just can reach the object of condensing surfaces active substance (at foam layer) and purification liquid phase main body.
Foam separation is made up of two primary processes: (1) solute to be separated is adsorbed on liquid-vapo(u)r interface; (2) collect by the material of steel foams to solution-air circle and use chemistry, heat or mechanical method to destroy foam, solute is extracted.Therefore its major equipment is foam column and demister.
Foam separating technology tool has the following advantages:
(1) foam separation structure is relatively simple, is easy to amplify;
(2) simple to operate, consume energy low;
(3) can continuously also can periodical operation;
(4) use at the initial stage of biological Downstream processing, process bulky diluent;
(5) as long as operational condition is reasonable in design, very high separation efficiency can be obtained.
After having carried out testing after analyzing the feature containing the acid waste water of endocrine disrupter and the research of the possibility research to foam separation technique, pickling waste waters is after foam separation process, and COD concentration, total P concentration has and significantly lowers.
(2) Fenton oxidation technique: Fenton's reaction is with ferrous ion (Fe 2+) be catalyzer hydrogen peroxide (H 2o 2) carry out the method for wastewater treatment of chemical oxidation.The system be made up of ferrous ion and hydrogen peroxide, also claims Fenton reagent, and it can generate the hydroxyl radical free radical of strong oxidizing property, generates organic free radical in aqueous and makes it structure deteriorate, final oxygenolysis with hardly degraded organic substance.
Fenton's reaction take ferrous ion as a series of free radical reactions of catalyzer.Principal reaction is roughly as follows:
Fe 2++H 2O 2==Fe 3++OH-+HO·
Fe 3++H 2O 2+OH-==Fe 2++H 2O+HO·
Fe 3++H 2O 2==Fe 2++H ++HO 2
HO 2+H 2O 2==H 2O+O 2↑+HO·
Fenton reagent is by above reaction, continuous generation HO (hydroxyl radical free radical, electrode potential 2.80EV, be only second to F2), make whole system have strong oxidizing property, chlorobenzene, Benzyl Chloride, grease etc. can be oxidized and be difficult to by general oxygenant (chlorine, clorox, dioxide peroxide, ozone, the electrode potential of ozone only has 2.23EV) material that is oxidized.Under the effect of hydroxyl radical free radical, the organic matter degradation of part difficult degradation in sewage is degradable organism, improves the biodegradability of sewage.
(3) A 2/ O technique: A 2/ O technique is primarily of hydrolysis acidification pool, anaerobic pond, aerobic nitrification pond composition.As Figure 1-1.Each reactor unit function:
1. anaerobic reactor, raw waste water and the phosphorous returned sluge of discharging from settling tank synchronously enter, and this reactor major function is release phosphorus, and partial organic substances is oxidized simultaneously;
2. anoxic reacter, premiere feature is denitrogenation, and nitric nitrogen is sent here by aerobic reactor by internal recycle, and the mixing liquid measure of circulation is comparatively large, is generally 2Q (Q is raw waste water flow);
3. aerobic reactor---aeration tank, this reaction member is multi-functional, removes BOD, and nitrated and absorption phosphorus etc. carries out all herein.Flow is that the mixed solution of 2Q is from being back to anoxic reacter here;
4. settling tank, function is mud-water separation, and a mud part is back to anaerobic reactor, and supernatant liquor is as the discharge of process water.
Process characteristic:
1. this technique can be called the simplest synchronous denitrogen dephosphorus technology in system, and total hrt is less than other class technique; This art breading efficiency generally can reach: BOD5 and SS is 90%-95%, and total nitrogen is more than 70%, and phosphorus is about 90%;
2. under anaerobism (anoxic), aerobic alternate run condition, thread fungus can not breed in a large number, and not easily mud filamentous bulking occurs, SVI value is generally less than 100;
3. the phosphorous height of mud, has higher fertilizer efficiency;
4. do not need dispensing in running, two A sections are only with stirring gently, and not increase dissolved oxygen for degree, working cost is low;
5. organic cooperation of anaerobism, anoxic, aerobic three kinds of different envrionment conditionss and different types of microorganisms flora, has the function of organics removal, denitrogenation dephosphorizing simultaneously.
(4) CMF technique: continuous membrane filter (Continuous Membrane Filtration, being called for short CMF) technology is a kind of novel membrane separation process process, by modular structure design, cross flow filter mode and intermittent type is adopted automatically to clean the system of (gas, washing process), a whole set of the closed continuous print membrane filtration system be combined into.
CMF systems technology feature:
1. adopt polypropylene hollow fiber microfiltration membrane or the ultra-filtration membrane of high strength, resistance to oxidation, easy cleaning, long service life;
2. due to the elasticity that PP hollow-fibre membrane is exclusive, micropore can be expanded, and adopts pressurized air backwash technique, makes this film have good membrane flux response rate;
3. pair raw water quality requires low, produces water as clear as crystal, and SDI stable≤3, is better than the inflow requirement of RO system;
4. Systematical control level of automation is high, simple to operate, effectively reduces labor intensity;
5. compact equipment, take up an area little, modular combination design is applicable to the water treatment of various scale;
6. facility investment and working cost cheap, at home and abroad in equipment of the same type, cost performance is the highest.
