Description
Invention field
The present invention relates to a kind of employing and can more effectively remove the intermittent aeration of nitrogen in the waste water and phosphorus and the waste water advanced processes system that catalytic oxidation, use flow into organic back denitrification process simultaneously.
Background technology
Pollutants in waste water matter can be divided into the nutrient salts such as organism, nitrogen and phosphorus with biochemical oxygen demand (BOD) (BOD) expression.So far, when the waste water processing station, mainly be with organism as process object, the nitrogen of considerable part and phosphorus are not removed and are discharged in rivers and creeks and the lake, thereby become the reason that eutrophication and red tide produce, so the waste water advanced processes becomes the practical expectation of people always.
The nitrogen in the past that can use when wastewater treatment, the process of removing of phosphorus roughly are divided into back denitrification process and preceding denitrification process.With methyl alcohol, acetate, the oxynitride that in the nitrogen oxidation trough of last stage, generates with follow-up denitrification reaction groove reductive after denitrification process have the advantage that running management is easy, processing efficiency is excellent, but owing to will prepare methyl alcohol, its problem is that required processing costs is too much.
In order to alleviate methyl alcohol is supplied with electron donor, the raising of processing costs, the preceding denitrification process that organism in the waste water is used for denitrogenation, its structure has following problem: need be with the reaction solution internal recycling of the nitrogen oxidation trough denitrification reaction groove to the last stage, the internal recycling flow is 2～4 times of inflow wastewater flow rate, therefore the pump facility take and expenditure on power and facilities management expense too much, also flow into the denitrification reaction groove from nitrogen oxidation trough free oxygen by internal recycling water adverse current, therefore cause organism to be wasted, and nitric efficiency is low, is difficult to turn round under top condition.
Because this internal recycling and the preparation problem that methyl alcohol brought research and development occurred the inflow organism in the waste water is reclaimed, replace the tendency of methyl alcohol in order to eliminate as the back denitrification process in denitrogenation source.Wherein an example generates organic acid and is used for denitrification reaction for flowing into the sedimentary living mud fermentation of solid organic matters in the waste water.
But this method has restricted, is applicable to that having the possible solid organic matters of precipitation is contained in situation in the waste water in a large number.
As the organism in the waste water is reclaimed, be used for other method of back denitrification reaction, this method flows into organism and is adsorbed in active mud for making, and makes its precipitation and is used for denitrification reaction afterwards.
This method is owing to the organism of the colloidal particle size with non-settling is also adsorbed, reclaims by active mud, therefore have researching value for organism deficiency, C/N than the advanced processes of low waste water, below describe by the content of this method to conventional art.
Fig. 1 represents to be used for and will flow into the example of the previous methods of the back denitrification reaction that organism that waste water contains adsorbs with active mud, and being described as follows of its process is described.
It is transferred by the organism that flows in the waste water, adsorb with active mud, the anaerobism adsorption tank that phosphorus is emitted, with the mud separation after the absorption, to go up clarification of water and flow into nitrogen oxidation trough the 1st settling tank, the organism and the oxidized nitrogen oxidation trough of oxynitride that contain in the separated last clarification of water of adsorb organic compound, the nitrogen oxidation trough flows out the 2nd settling tank that water is carried out solid-liquid separation, the oxynitride that contains in the last clarification of water of the 2nd settling tank is by the active mud adsorbed organic matter reductive denitrifying tank of transferring from the 1st settling tank, remaining organism is decomposed, finish the aerator tank again of the surplus picked-up reaction of phosphorus, aerator tank is again flowed out water carry out solid-liquid separation, to precipitate mud and be transplanted on adsorption tank, last clarification of water constitutes as effusive the 3rd settling tank for the treatment of water.
According to the method for Fig. 1, in 3 settling tanks, each settling tank all needs mud to transfer pipe arrangement, mud shifting pump facility, therefore needs too much setup fee and keeps overheads, floor space.Especially, complicated owing to the unit process number is many, therefore have the problem of running management difficulty, so be not the method that hope is used.
Fig. 2 is the method in the past after a method to Fig. 1 is improved, and it constitutes at nitrogen oxidation trough filled biomass membrane carrier, and microorganic adhesion is bred in carrier, has omitted 1 follow-up settling tank, and adsorption tank is made of the aerobism groove.Because adsorption tank is the aerobism reactive tank, therefore the deposition efficiency in the 1st settling tank is improved, and before the mud that the 1st settling tank is recovered was shifted into denitrifying tank, its formation must comprise through the dephosphorization groove.Owing to appended the dephosphorization groove, need setup fee and keep overheads, wide space, the unit process number is many and complexity is not still eliminated.In addition, adsorption tank is the single condition of aerobism, and under the aerobism condition, the oxidation operation amount increases, and its formation is wasted the inflow organism that should be used for denitrification reaction to greatest extent.
The related method shown in Figure 3 of technology in the past that will be used for denitrification reaction by the inflow organism that active mud adsorbs, owing to be filled with biofilm carrier at the nitrogen oxidation trough, therefore 1 settling tank in intermediate stage is omitted, since the adsorption tank that under anaerobism, turns round, the mud that reclaims in the 1st settling tank before flowing into denitrifying tank the dephosphorization groove of process also can be omitted.Therefore, method shown in Figure 3 is that process is the simplest in the conventional art, in Korea S, be method although it is found that than the more Zao exploitation of method illustrated in figures 1 and 2 of nearest research, simple property that technology constitutes and economy aspect further improve (Water Science Technology.Vol.34 on the contrary, No.1-2, pp.119-128,1996).
But method shown in Figure 3 is in order to be applied to have the processing occasion of actual scale, and also existing needs the problem that solves, below by the order of unit process this problem described.
At first, this problem is relevant with the above-mentioned adsorption tank in first process, because above-mentioned adsorption tank turns round under anaerobic single condition, have the advantage that can save other dephosphorisation reaction groove, still, in the 2nd settling tank, the active mud of stagnating under the non-aeration condition at 2～3 hours still is detained under the anaerobism condition in adsorption tank, therefore might actively reduce, flow into the possible deterioration of organic adsorption efficiency, the settleability in the 1st settling tank might reduce.
If the adsorption efficiency deterioration, organic loading increases in follow-up catalytic oxidation groove, and organism is wasted, and the oxygen demand increases, and aeration power increases, and the nitrogen oxidation also reduces.If the precipitation threshold of mud reduces, the organic loading that then flows into the catalytic oxidation groove increases, and produces vicious cycle.
Below be and the relevant problem of above-mentioned catalytic oxidation groove of mode in the past that because above-mentioned catalytic oxidation groove turns round under the single condition of aerobism, so the nitrogen oxidation is finished smoothly.But, oxidized fully the nitrogen oxidising process from the dissolved organic matter that the 1st settling tank flows into, therefore can't all be used for denitrification reaction.Therefore, organism in flowing into waste water mainly is made of colloidal particle, when having littler solvability, can't be adsorbed by active mud at adsorption tank, almost all flow into above-mentioned catalytic oxidation grooves and oxidized, because the solid organic matters that is adsorbed by active mud is also few, therefore organism deficiency in follow-up denitrification reaction groove, nitrogen is removed efficiency degradation.Because drainage is excessive, with the processing field certain distance is arranged, if the waste water residence time prolongs, solid organic matters almost disintegrates to become and has solvability, so the problems referred to above will become more deep.
Especially, C/N than low water in, be difficult to be adsorbed by active mud, can't reclaim, no matter dissolved organic matter can be applied to denitrification reaction to greatest extent, if be technology in the past, flow into into the deliquescent organism of the catalytic oxidation groove of aerobism condition will be all oxidized.In addition, because above-mentioned catalytic oxidation groove is turned round under the aerobism condition continuously, so the oxygen transmission efficiency is low, the aeration dynamic efficiency also can't satisfy.
Because above-mentioned denitrifying tank is the reactive tank that is in the anaerobism state for stirring with non-aeration usually, so its structure can't be tackled the variation of inflow condition neatly.For example, when the nitrogen compound concentration that flows into water increases, when the nitrogen oxidation can't fully be carried out in the catalytic oxidation groove of last stage, in above-mentioned denitrifying tank, can't normally carry out denitrification reaction, the removal deficiency of nitrogen.
As the problem relevant with the non-Economy of settling tank, in said process, need 2 settling tanks, from above-mentioned 2 settling tanks, extract mud out, be transplanted on respectively in its reactive tank, therefore need 2 groups mud shifting pump, thereby need facility expense and expenditure on power too much.
As the problem that in the advanced processes process that standard activity mud process is related with above-mentioned technology is in the past improved, occurs, so far, Korea S uses nearly all waste water processing station by mainly carrying out standard activity mud process that the 1st settling tank, active mud aerator tank, the 2nd settling tank that organism handles simply constitute and builds and turn round, and is extremely urgent to the improvement of advanced processes process.But, Korea S waste water C/N is than low, the insufficient situation of inflow organism that is used for advanced processes is many, therefore wishes to adopt and can reclaim organic efficient back denitrogenation method as much as possible, thereby proposed to flow into the organic method that is used for the back denitrification reaction with slurry conveyed absorption.
But, be adsorbed groove alternate structure owing to being improved as the advanced processes facility less than mud process for general's standard activity in the past, most cases does not need the occupation of land of building, adsorbed organic mud in order to reclaim, append the inflow slurry conveyed to the 1st settling tank, append the mud of inflow owing to extract out from the bottom of settling tank, if with flow more is benchmark, can not produce by the insufficient problem of settling tank water surface discharge, but, owing to have too much flow to flow out, therefore produce the deterioration of settling tank efficient sometimes owing to whirling motion.
In addition, most occasions are to be provided with the surface aeration machine that is rotated rotating aeration of car and stirring at the water surface in the standard activity mud aerator tank in the past.At this moment, immobilization carrier becomes the obstacle of aeration and stirring, in order not become the stirring obstacle of aerator tank, flowing carrier and rotation car are bumped and breakage, the biofilm carrier that uses is limited, when the surface aeration machine of setting is replaced with air exhaust type,, and bring noneconomic problem because original device is discarded and newly-increased.
The present invention proposes for the problem that solves above-mentioned conventional art existence, therefore its purpose is to provide a kind of organic rate of recovery raising that makes, can tackle the variation of inflow condition flexibly, can be easy and be applicable to that economically the advanced processes when in the past handling improves, high-level efficiency is used the organic advanced processes system that flows into.
Summary of the invention
In order to solve owing to adsorption tank in technology in the past constitutes the problem that produces by aerobic or anaerobic single reaction groove, pressing adsorption tank, the 1st settling tank, the catalytic oxidation groove, aerator tank again, the order of the 2nd settling tank, the precipitation mud of the 2nd settling tank is transplanted on first reactive tank, the precipitation mud of the 1st settling tank is transported to second reactive tank and in the technology that constitutes, for anaerobism and aerobic condition are hocketed, in the present invention, above-mentioned adsorption tank constitutes by possessing the intermittent aeration groove that makes aeration and non-aeration stir intersection intermittent aeration means repeatedly according to the condition that sets.
According to above-mentioned intermittent aeration groove, can eliminate following non-Economy factor: if for adopting the adsorption tank of the conventional art shown in Figure 2 that turns round under the single condition of aerobism, the oxidized and waste of organism under continuous aerobic condition; Flowing into the oxynitride that is contained the slurry conveyed of above-mentioned aerobism adsorption tank from the 2nd settling tank does not have denitrogenation and flows in the follow-up process; For dephosphorisation reaction must be provided with other dephosphorisation reaction groove that the mud that leads to the 1st settling tank is transferred pipeline.
In addition, can alleviate following problems: adopting in the technology in the past shown in Figure 3 that under anaerobic single condition, turns round, problem as adsorption tank, the active mud of carrying from the 2nd settling tank of non-aeration halted state is owing to flow into the adsorption tank of anaerobism condition, be exposed to for a long time can not the non-aeration condition of continuously feeding air under, therefore the activity of active mud reduces.In addition, the problem that precipitation threshold reduces in the 1st settling tank also is improved.
Adopt above-mentioned intermittent aeration groove of the present invention, under the anaerobism condition of non-aeration whipped state, finished the denitrification reaction that flows into the oxynitride that is contained in the mud, finished the dephosphorisation reaction of from active mud microorganism, emitting phosphorus; In same reactive tank, carry out aeration again, if be converted to the aerobism condition, owing to adopting active mud microorganism to finish the picked-up that surpasses of phosphorus, therefore the phosphorus that flows in the water is removed, because the aerobism condition is by repeatedly, so microbic activity and settleability improve.Like this, intersection by anaerobism and aerobic condition repeatedly, organism is wasted on the one hand, active and settleability reduces, organic adsorptive capacity does not reduce, even do not append other dephosphorisation reaction groove of the slurry transportation pipeline that leads to the 1st settling tank, can efficiently phosphorus be removed yet, owing to be the intermittent aeration groove of periodically aeration being opened again under the anaerobism condition of dissolved oxygen element not having, so aeration efficient also is enhanced.
Here, the action of above-mentioned intermittent aeration means is DO consistency controller and the ORP controller interlock that timer or its induction part are provided with in reactive tank.Especially, in the process that the adsorption efficiency and the settleability of adsorption tank are confirmed, in order to adopt to make induction part to the adjusting reflection in intermittent aeration cycle in the MLSS tester of the water surface setting of the 1st settling tank and the method for above-mentioned aeration means interlock.
Above-mentioned intermittent aeration means can be used the associated plant of agitator in air dispelling device and the water, and the associated plant of agitator or contriver have invented in surface aeration machine and the water, the known technology such as intermittent aeration device of pump-injector mode commonly used.
In addition, be the problem that the single conditioned response groove of aerobism produces in order to eliminate catalytic oxidation groove owing to conventional art, in the present invention, it is used in the intermittent aeration catalytic oxidation groove that has been equipped with the intermittent aeration means in the above-mentioned catalytic oxidation groove and constitutes.Promptly, above-mentioned intermittent aeration catalytic oxidation groove is when aeration state, aerobism condition, finished the nitrogen oxidation that nitrogen compound is converted into nitronic acid salt, under non-aeration condition, anaerobism state, oxynitride that generates during aerobism and the oxynitride that contains in the slurry conveyed that the 1st settling tank flows into are finished denitrification reaction from the deliquescent different decomposed organic reduction of having of the 1st settling tank inflow, therefore insufficient organism is used for denitrification reaction to greatest extent flexibly, has improved the removal efficient of nitrogen.
