Description
Technical field
The present invention is the improvement to acidication method and hydrolysis acidification pool in the wastewater treatment, relate in particular to a kind of settling tank that omits, do not need mud to reflux, with water inlet mix, quiescent setting, water outlet be the continuous hydrolysis acidification technique and the hydrolysis acidification pool of basic loop cycle.
Background technology
Anaerobic hydrolysis-acidification is an effective means of handling high density and/or organic wastewater with difficult degradation thereby, along with the sewage disposal water outlet requires to bring up to I level A standard from I level B standard, acidication efficient becomes a key that contains the further low-cost reduction water outlet of indegradable industrial effluent Sewage Plant COD.The routine hydrolysis acidification technique divides mud method (suspension growth mode) and embrane method (apposition growth mode) two big classes usually.
Mud method acidication technology, the high density anaerobe is that active sludge adsorbs decomposition COD to anaerobic fixed film reactor in the pond by keeping, for active sludge being run off and keeping high sludge concentration in the hydrolytic tank, settling tank with treatment capacity is set in the hydrolytic tank back usually, by the post precipitation mud-water separation mud is refluxed, guarantee that biological concentration is to adapt to the impact that the water yield changes in the hydrolytic tank, promptly hydrolysis biochemical reaction and precipitate and separate mud are finished at two separate tanks internal fixing respectively.The complete mixed hydrolysis acidifying of Chinese patent CN1693233 urban sewage treatment process for example, municipal effluent is sent into hydrolysis acidification pool, stir, the sewage of discharging from hydrolysis acidification pool enters settling tank, and mud is back to hydrolysis acidification pool, the sewage that comes out from settling tank enters follow-up aerobic treatment operation.Mud method acidication need be provided with the treatment capacity settling tank, and mud return-flow system (reflux pipeline and refluxing unit) need be set, and has increased occupation of land and construction costs, and working cost; Secondly, trade effluent content is higher in sewage, and difficult degradation dissolved organic matter content is higher and toxic to microorganism, the loose not free settling of biological floe that causes hydrolysis to generate, common precipitate and separate is difficult to reach required sludge concentration, also mainly come inorganic particle suspended substance in the water even reach required sludge concentration, cause sludge activity lower, thereby influence hydrolysis effect; Besides, since the hydrolysis biochemical reaction be directly intake at a hydrolysis acidification pool, water outlet, the Inlet and outlet water short circuit phenomenon can appear when stirring is short of power, can not guarantee full pond sludge concentration homogeneity, also can influence treatment effect, cause impact follow-up continuous operation aerobic system.
Need build the shortcoming of settling tank at the mud method, many improvement and array configuration appear, as baffled reactor (ABR), flow lifting type Sludge Bed etc., though making acidication technology biochemical reaction and muddy water precipitate and separate carries out in the body of same pond simultaneously, finish hydrolysis reaction when sewage rises and sink to separating in the pond, do not need to build settling tank in addition and saved land used with mud.But be subjected to the required conditionality of mud-water separation in the body of same pond, current can't reach sufficient turbulent fluctuation allows microorganism contact with the COD thorough mixing, and the scope of application has limitation.For example the baffle plate type reactor is based on mud and forms particulate state and sink easily, but only is suitable for the easy biochemical organic waste water of high density, and when water inlet was difficult to biochemistry, it was little and loose to form particle, and separation efficiency just can reduce; The flow lifting type Sludge Bed is based on rising sewage when passing mud layer to suspending or the absorption of colloidal COD is decomposed, and lower to the removal efficient of solvability COD.Secondly, two processes of hydrolysis reaction and precipitate and separate are carried out in the body of same pond simultaneously, biochemical reaction requires good mixing to flow, and mud-water separation requires the static slow contradiction of current to be difficult to coordinate, all can't operate in optimum regime separately, and the scope that ascending current and decline mud reach running balance is very little, so the actual motion instability.
Chinese patent CN1962480 peripherally-distributed water deflection composite reactor for hydrolysis and acidification adopts three grades of concentric(al) circless to form the pond body, has made up flow lifting type, traverse baffle, combined stuffing.Though the deficiency that adopts upflow-type reactor to remedy the embrane method biofilm and come off, though occupation of land was bigger when a plurality of pond was arranged but take up an area of less in circular pond itself, use filler to exist the embrane method investment big, filler is safeguarded inconvenient, filler easily stops up, and the shortcoming of structure and operational management complexity.
Chinese patent CN101003404 upward flow type composite anaerobic hydrolysis and acidification treater and method thereof are by the circulation realization acidication of suspended sludge.Need to keep certain upflow velocity by adjusting pump flow, make mud be in suspended state, this method has increased operation energy consumption, and suspend or colloidal COD principle owing to be still by sludge absorption, the same existence removed the lower shortcoming of efficient to solvability COD, can only be applicable to the specified conditions of those COD for suspension or colloidal.
Chinese patent CN101205108 has the high-efficiency composite hydrolysis acidification pool technology of sewage disposal and sludge reduction functions concurrently, have simultaneously in hydrolysis acidification pool that the backflow excess sludge is batched, water conservancy diversion flap and Turbulent wing panel strengthen function facilities such as reaction mass transfer, efficient sloping plate deposition, in same hydrolysis acidification pool, realize anerobic sowage biological degradation, solid-phase contaminants high efficiency separation and hold back, function such as mud is subdued.Replace the independently settling tank of primary sedimentation pond and mud method by in the pond, establishing to sloping plate deposition, strengthen suspended substance and hold back efficient,, realize the decrement treatment of solid-phase contaminants and mud simultaneously to backflow excess sludge hydrolysis liquefaction.But this method not only exists colloid and dissolubility pollutant are removed inefficient deficiency, and multiple technologies are combined, cause structure and operational management more complicated, to the adaptive faculty reduction of amount of inlet water water quality.
Embrane method acidication technology, for example Chinese patent CN201386044, CN201330193 are described, and biological attachment is on filler, and COD is decomposed in effluent stream microorganism absorption when filler.By filler fixed growth microbial film, can not need mud-water separation and backflow, save and taken up an area of big settling tank part, but the biofilm difficulty, coming off of fixed biofilm is its two big deficiency, for example can cause the microbial film big area to come off when water quality and quantity fluctuates, cause the fluctuation of acidication efficient, the effluent quality fluctuation is unstable, secondly, the investment of biofilm filler is big, and needs regular maintenance, replacing, has increased working cost and maintenance, replacing workload.
Above-mentioned deficiency still has is worth improved place.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, and a kind of sewage hydrolyzing souring method that does not need to be provided with separately settling tank is provided.
Another object of the present invention is to provide a kind of realization aforesaid method, hydrolysis acidification pool simple in structure.
The present invention's first purpose realizes, the main improvement is to make sewage hydrolyzing acidifying whole process, at least being divided into into, water mixes reaction (being called for short water inlet stirs), static mud-water separation (abbreviation quiescent setting), three successive processess of water outlet, three processes are finished in three or above different pond respectively simultaneously, successively finish the hydrolysis sequential process with the preface batch mode in the same pond, handle and realize being back to back water, thereby overcome existing acidication needs to finish respectively fixed function in two ponds deficiency, realize the object of the invention.Specifically, sewage hydrolyzing souring method of the present invention, comprise hydrolysis biochemical reaction, mud-water separation, water stirs to it is characterized in that being divided into the acidication process at least, three or respectively of quiescent settings, three sequential processes of water outlet, three processes to finish simultaneously in the upper storage reservoir, wherein aforementioned three processes are then successively finished in turn in each pond, and each pond water of being back to back.
Before enumerating embodiment, do a summary introduction by the basic function and the effect that can reach the present invention earlier, make those skilled in the art have one clearly to understand to the art of this patent scheme.
Sewage hydrolyzing souring method of the present invention, stir by hydrolytic process being divided into water inlet at least, quiescent setting, three processes of water outlet are carried out in turn, and three processes are carried out at least simultaneously in three or above different pond, realize continuous hydrolysis by the water of being back to back, the acidication whole process is separately carried out in three or the above separate tanks that more adapts to each stage condition of acidication, have better hydrolysis effect.Promptly when continuous hydrolysis, water mixes at least always to have a pond to be in into, and a pond is in quiescent setting, and a pond is in water state, and each treating pond forms the water of being back to back by communicating pipe or canal and moves continuously; And three processes of hydrolysis are moved in each separate single pond continuously in alternate cycle in treating processes.Say that simply in the continuous hydrolysis treating processes, at least three separate tanks are three processes that are hydrolyzed simultaneously, in the treating pond be in chronological sequence in turn preface criticize three processes of hydrolysis.
In addition, when big the and/or processing requirements of the hydrolysis difficulty of disposing of sewage is high, can also be regulated by increasing treating pond quantity, after the agitation phases of for example can in the same work period, intaking, set up the independently stirring reaction stage again, thereby make hydrolysis cycle regulating more meticulous (hydrolytic process is got carefully, regulates and control meticulous).Four reaction tanks for example are set, corresponding into water stirring, stirring reaction, quiescent setting, four sequential processes of water outlet of being divided in each pond, four processes are finished in four separate tanks respectively simultaneously.
Hydrolysis acidification pool of the present invention comprises and handles single pond, it is characterized in that hydrolysis acidification pool has three at least, and is adjacent and/or be oppositely arranged, and has connecting passage to constitute technology to be communicated with, to be respectively equipped with whipping appts and inlet and outlet control valve door in each treating pond.
Among the present invention:
Each treating pond is born various process in three processes of acidication respectively at synchronization, then bears three processes of acidication in turn at different time, and acidication is continuously carry out.Each pond is provided with arrangement, have no special requirements from function, can arrange arbitrarily, forming technology by communication passage is communicated with, for shortening connection line, and saving is taken up an area of, so adopt adjacent and/or be oppositely arranged, can also make the shared pool wall of adjacent treating pond save construction investment (being particularly useful for the rectangular configuration pond) like this, this structure also helps the setting of communication passage simultaneously, and simplify each treating pond and be communicated with communication passage, for example can on shared pool wall, offer valve control water hole, and other water treatments adjacent pool commonly used is crossed stream mode, but it is necessary that this is not technology of the present invention institute, if do not consider to save factors such as land used, can divide fully to be arranged, this can't influence the enforcement of this patent method.Consider that simultaneously each pond will finish the acidication whole process in turn, so whipping appts and inlet and outlet control valve door all are set in each pond.The same prior art of the enterprising flowing water Valve in each pond is mainly used in the control Inlet and outlet water, controls automatically for convenient the realization, better adopts electric control valve.
Communication passage, main effect is communicated with each treating pond, make each pond replace three processes of acidication, according to each treating pond arrangement mode and processing requirement difference, the communication passage form also can have different the variation, for example can be a connectivity slot or pipe, also can be a relatively large reaction tank, can also be simplified to a connected well, look the processing water yield and determine.Wherein better be to adopt the connectivity slot form, for example can expand as reaction tank, be built-in with whipping appts, not only can make water inlet, water outlet be plug-flow and switch, and higher, or handle waste water difficult degradation composition and amount for a long time at processing requirements, it can also be increased as a relatively large agitating reaction pond, rise simultaneously to be communicated with and switch and reaction stop dual-use function,, improve hydrolysis ability to increase the system response total residence time.
The interior agitating device of each treating pond (comprising connected reaction pond), be mainly used in different time and finish the function that mixes in the acidication process, in theory whipping appts is not particularly limited, as long as can realize that the water treatment that fully mixes function can both be employed with whipping appts, look pond type and size and select to adopt.For realizing automatic control, each pond whipping appts can be by time variable control working time and/or operation stirring intensity.
As previously mentioned, when the big and/or processing requirements of the hydrolysis difficulty of disposing of sewage is high, can also be regulated, so treating pond of the present invention can be provided with 4 or more as required, form technology by pipeline and be communicated with by increasing treating pond quantity.Take up an area of utilization ratio for improving to greatest extent, each pond design is a kind of better to be that each pond is onesize, can certainly be that 3 ponds are onesize, and size is determined according to design requirements in the 4th pond.
Sewage hydrolyzing souring method of the present invention (being called for short CCHAS technology) and hydrolysis acidification pool, water mixes owing to make the acidication process be divided into into, quiescent setting, three sequential processes of water outlet, and three processes at least three or with upper storage reservoir in simultaneously/finish respectively, in the treating pond then in chronological sequence in turn preface criticize and finish aforementioned three processes, and the water of being back to back.With respect to prior art, because hydrolysis divides process stage to finish, can guarantee required top condition of each stage of hydrolysis in different ponds, improve hydrolysis effect, many ponds are carried out simultaneously and can be realized continuous hydrolysis.In two ponds, finish fixed routine than the prior art acidication respectively, can omit and establish settling tank in addition, save and take up an area of; Hydrolytic process is finished in more single pond, has better solved biochemical reaction requirement good mixing and has flowed, and mud-water separation requires current immobilized contradiction.Secondly, acidication muddy water separates the back water outlet through quiescent setting, the less looser microorganism that difficult precipitation forms the mud flco is separated and is stayed in the biological tank, biophase is horn of plenty more, special bacterium is rised in value becomes dominant bacteria, makes to obtain decomposition originally by the macromole COD that acidication is opened, thereby has ensured the processing efficiency of subsequent treatment process, and technology regulation and control handiness is good, does not need filler.Besides, owing to be to split three treating ponds by handling water yield design, acidication takes up an area of the total area not to be had to increase substantially, overcome conventional mud method hydrolytic tank, for keeping high sludge concentration, behind the hydrolytic tank settling tank must be set, increase the deficiency of taking up an area of and investing, can save the soil more than 20%, save investment more than 30%.Treating pond of the present invention can modular design and expansion, more helps waste water treatment engineering built by separate periods and enlarging.In addition, each treating pond of this method replaces Inlet and outlet water, belong to again with the activated sludge process is the main body acidication, sludge concentration and activity are higher in the pond, and biomass is big, mud age (SRT) is long, does not only need to be provided with filler, and can keep remarkable advantages bacterial classification in the hydrolytic tank, the specific aim that reaches all contaminations is removed, and can reduce the impact to follow-up continuous operation aerobic system, and can omit the mud refluxing unit.Acidication divides three process branch ponds to carry out simultaneously, and is undertaken by UNICOM's unit circulation plug-flow, also the Inlet and outlet water short circuit phenomenon can not occur, has guaranteed each pond sludge concentration homogeneity, can guarantee hydrolysis effect.Each reaction tank periodically moves with the preface batch mode, not only can realize the water of being back to back, and operating parameter is easy to adjust, each cycle length and the period length conveniently regulating and controlling that all can be in operation wherein, it is more flexible that variable range is counted in the increase pond, thereby strengthened capacity of resisting impact load, decomposing the from generation to generation long special bacterium of hardly degraded organic substance is simultaneously rised in value even is become dominant bacteria, make more hardly degraded organic substance can be broken down into the small molecules easily biodegradable organics, and help the final organic pollutant of removing in follow-up aerobe pond.Plane, treatment process pond combined and instant, adjacent and/or build jointly relatively, more can save soil and construction costs.The inventive method is particularly useful for cities and towns industry and sanitary sewage disposal, both can be used for existing sewage work's hydrolysis acidification pool and equalizing tank upgrading also be can be used for newly-built sewage work, and according to handling water yield built by separate periods.Build the many lattice of Chi Tiwei jointly, the structure stress condition is good.Acidication process is at three and finishes simultaneously with upper storage reservoir, and acidication three processes are alternately finished in single pond, is different from the key distinction feature of existing acidication for the inventive method and pond type.
Below in conjunction with several specific embodiments; essence of the present invention is further understood in exemplary illustration and help; but the embodiment detail only is for the present invention is described; do not represent the present invention to conceive whole technical schemes down; therefore should not be construed as the total technical scheme of the present invention is limited; some are In the view of the technician; the unsubstantiality that does not depart from the present invention's design increases and/or change; for example simple the change or replacement of technical characterictic to have same or similar technique effect all belongs to protection domain of the present invention.
