Description
The application divides an application, and the applying date of original application is: 2005.2.30, application number are: 200510003422.5, denomination of invention is: trade effluent and municipal wastewater treatment facility and processing method thereof.
Technical field
The invention belongs to water treatment field, be meant a kind of trade effluent and municipal wastewater treatment method especially.
Background technology
At present, the harm that the paper industry environmental pollution causes is fairly obvious, especially on the pulp production link of paper, because production technique such as the cooking process that adopts, oxidation style can produce a large amount of waste water in process of production.Adopt traditional waste water control method, the efficient of administering sewage is low; Water treating equipment are invested, working cost is big; The energy consumption height has caused many papermaking enterprises that factory effluent is discharged in river, river, the lake water steathily, has seriously polluted water resources, has polluted environment.In addition, the most of municipal effluent of China also directly discharges without effectively handling, and consequent water pollution has become serious environmental problem.
External many new technologies, novel process were introduced into China to nineteen ninety-five in 1975, all were applied in China municipal sewage plant as B method, oxidation ditch process, A/O technology, A2O method, SBR method.Simultaneously, more external advanced persons, the sewage disposal specific equipment has also entered the wastewater treatment in China industry market efficiently, as equipment such as grid maker, submersible pump, desanding device, mud scraper, aerator, gas blower, sludge pump, water extracter, biogas generator, methane boiler, sludge digestion stirring systems.
The municipal sewage plant that China built the eighties in the past is most of to adopt common aeration active sludge treatment process, because this technology is major objective to remove BOD and SS mainly, very low to the clearance of nitrogen phosphorus.
What China adopted more than 80% existing municipal sewage plant is activated sludge process, and all the other adopt one-level processing, enhanced primary processing, stabilization pond method and soil facture etc.
Along with the raising of China to the quality of water environment requirement, revised country " integrated wastewater discharge standard " is (GB8978-1996) also more and more tighter, particularly the requirement to water outlet nitrogen, phosphorus improves, and makes newly-built municipal sewage plant must consider effective removal problem of nitrogen phosphorus.Developed improvement A2O technology and returned sluge denitrification biological phosphate-eliminating technology thus, and begun in actual engineering, to use.Newly-built reaching in the technology that the municipal sewage plant adopted of building, various types of activated sludge processes still are main flow, account for more than 90%, all the other then reach the sewage treatment technologies such as the natural, ecological method of purification that combine with other treatment process for one-level processing, enhanced primary processing, stabilization pond method, biomembrance process.
The industrial sewage processing technological flow mainly comprises workshop sections such as aeration anaerobic treatment, precipitation process, aerobic treatment.Be major objective mainly to remove BOD and SS, but very low to the clearance of nitrogen, phosphorus.
The municipal wastewater processing technological flow mainly comprises workshop sections such as mechanical treatment, biochemical treatment (waterline), sludge treatment.The system that is made of mechanical treatment and biochemical treatment belongs to the second-stage treatment system, and its BOD5 and SS clearance can reach 90%～98%.Treatment effect between firsts and seconds is handled be commonly referred to as that enhanced primary is handled, one-level half is handled or not exclusively level handle, mainly contain high loading biological treatment and chemical method two big classes, BOD5 clearance 45%～75%.Second-stage treatment system with biological dephosphorize denitrification function is commonly referred to degree of depth second-stage treatment.In order to remove specific material, the treatment system that is provided with after second-stage treatment belongs to tertiary treatment, for example: chemical dephosphorization, flocculation filtration, charcoal absorption etc.
One-level biological treatment system is mainly desilting, oil removing, precipitation, and purpose is to remove suspended substance and small part CODcr, BOD5.Along with quantity of wastewater effluent increases day by day, the aggravation of water pollution, and the raising of emission standard, developing into two stage biological handles, on behalf of technology, it technologies such as the conventional oxidation pool, activated sludge process, biological filter, bio-contact oxidation are arranged, and mainly removes CODcr, BOD5, and part NH3-N.Along with deepening continuously of research work, people recognize the organic matter of being not only that causes pollution, and the ammonia of inorganic nature, phosphorus also are the major causes of body eutrophication.Therefore, more strict emission control standards has all been formulated in countries in the world, is removing the organic nutritive substances such as nitrogen, phosphorus of removing simultaneously.In order to adapt to this requirement, develop a collection of degree of depth second-stage treatment technology, or be called secondary half treatment process, mainly contain technologies such as oxidation ditch, integrated activated sludge processing, BAF, the Biostatic pool.
It all is the suspended biological facture that derives from from activated sludge process that current domestic popular sewage treatment process has these technologies such as common aeration (conventional activated sludge method), AB method, oxidation ditch process, SBR method, A2/O method, A/O method, UNITANK method.
1, common aeration (conventional activated sludge method): it is the technology that occurs the earliest, still has great vitality so far, and treatment effect is good, the sludge loading height, Chi Rong is long-pending little, and power consumption is economized, but common aeration does not possess the denitrogenation dephosphorizing function, only can satisfy BOD5, CODcr, three effluent index of SS.
2, SBR method (sequence batch (): generally form, rotate water inlet, aeration, precipitation, left-falling stroke water, leave standstill by one group of four pond.This technology is original treatment process, in modern technologies, can be regarded as anaerobism (dephosphorization), aerobic (remove BOD5 and nitrated), anoxic (denitrogenation), precipitation (removing SS) and combine in the pond, sedimentary mud is retained in the pond and saves mud and take out and rise reflow process.This method is applicable to that the water yield, water quality discharges uniform trade effluent, and can save equalizing tank, reduces investment outlay; But large-scale wastewater treatment plant there is not superiority.
3, oxidation ditch process: oxidation ditch is actually a kind of distortion of activated sludge process, because of the mixed solution of its waste water and active sludge constantly circulates in the channel of cyclic aeration tank, so the someone is called " circulated aeration tank " again.Original oxidation ditch belongs to extended aeration, does not establish primary sedimentation pond, and sewage reaches the nitrated stage, obtains corresponding aerobic treatment, measures less and slaking; Oxidation ditch is with changeing the brush surface aeration, and management is simple.Originally original oxidation ditch is discontinuous running, after develop into continuous operation, set up secondary sedimentation basins, aeration and depositing technology are separated, kinds of processes appears then: DE formula, DT formula, increased preposition anaerobic zone and rearmounted settling tank, return-flow system, and possessed the denitrogenation dephosphorizing function, but its power consumption is bigger, and running expense is higher.
4, A2/O method: the technology of the general denitrogenation dephosphorizing of using always is A2/O (anaerobism, anoxic, aerobic) method.Phosphorus discharges at anaerobic zone, absorbs at aerobic zone, reaches the dephosphorization purpose, and pollutent is removed COD and BOD in the oxidized degraded of aerobic zone; Under the effect of nitrifier, the ammonia nitrogen that organic oxygen transforms is converted into nitrous acid nitrogen and nitrate nitrogen in succession simultaneously; The macro-mixing liquid that contains nitrate nitrogen is back to the oxygen-starved area and carries out denitrification denitrogenation; But the sludge treatment workload is big in its mud reflux technique, and energy-saving effect is poor.
5, AB method: promptly adsorb and two sections biological treatments of biological degradation, generally do not establish preliminary sedimentation tank.The A section is the biological absorption phase of high loading, promptly makes full use of the microorganism (bacterium) in the sewage, is adsorbed as the main BOD of removal with biology, and its running status is with higher sludge loading removal organism more than 50% in short aeration time; The B section is property mud method operation routinely then, and sewage is after handling through the A section, and the BOD concentration that enter the B section this moment reduces significantly, and the time that reaches nitrated is shortened dramatically, and has also reduced the B section and has handled the volume of structures, but also reduced construction costs.Conventional AB method, the about 50-70% of TP clearance, the TN clearance is about 30-40%.The AB method is applicable to the processing high concentration organic sewage, and the BOD removal is worth about 300-350mg/L.
6, UNITANK method: this technology is a kind of novel process based on activated sludge process.Characteristics are that aeration and precipitation are formed one.This technology is divided into some lattice with the pond, head and end alternative aeration and precipitation; But this method does not possess the denitrogenation dephosphorizing function.
In a word, aforesaid method does not still fundamentally solve and administers effluent problem.

A kind of trade effluent and municipal wastewater treatment method, it is with after adding flocculation agent in the sewage, whole flow process is in the change flow morphology, in biochemical polyreaction and the mechanical-physical moving process, pollution factor produces waddingization rapidly in flow process free, granulometric impurity tiny in the water can be generated to be convenient to filtering hydrophilic water-fast agglomerate material.Whole wadding generative process only needs very short time (generally being no more than 40 seconds), just 95% above pollution substance dehydration sub-argument can be become dry-matter.
Technology processing system of the present invention, it mainly comprises: barrier pre-treatment, equalizing tank, the mixing of multistage water, water quality adjusting system, dynamically flocculation, metal membrane filter unit, backwater treatment system.
The barrier pre-treatment: former water is introduced into thick barrier through conduit, is used for removing foreign material such as water hair, fiber, turns round normally to guarantee subsequent disposal safety.The barrier retaining power is strong, adopts full-automatic device, need not artificial periodic cleaning interception dirt.
Equalizing tank: because wastewater flow rate and enter the inhomogeneous of impurity in the discharge of wastewater process, making flow, concentration and the temperature of waste water has variation in a big way in round the clock.For guaranteeing water conditioning, be not subjected to the influence of waste water peak flow or change in concentration, so utilize regulating tank to come regulating pondage and water quality.In addition, waste water can neutralize in regulating tank, and the sewage of discharging is handled, and is used for homogenizing water quality, regulating pondage.With " building municipal sewage treatment design specifications " is foundation, and this pool volume plays homogenizing water quality, prevents sedimentary effect by handling water yield design.
Flocculation and line-blending: the core that the mixed stage of intelligence flocculation and pipeline has been concentrated the entire treatment processing method.Add intelligent flocculation agent in this technical process process, applied fluid dynamics, principle of electrophoresis by process synergic effects such as " compression double electric layer effect ", " charge neutrality ", " adsorption bridgings ", reach flocculating effect.
(1) compression double electric layer effect: adsorption layer and diffusion layer are collectively referred to as electrostatic double layer.Cation concentration reduces from inside to outside gradually in the electrostatic double layer, until with water in cation concentration about equally.Therefore, electrostatic double layer has certain thickness.Add a large amount of ionogen as Xiang Shuizhong, then its positive ion will be clamp-oned diffusion layer and make it attenuation; And then clamp-on adsorption layer, and the electronegativity on glue nuclear surface is reduced, this effect claims compression double electric layer.When electrostatic double layer is compressed, intergranular static is scolded and can will be reduced, and when the kinetic energy of reducing to less than the particle pedesis, particle is adsorption-condensation mutually just.
(2) charge neutrality effect: more than be cohesion between micelle of the same race, and the charge neutrality effect is meant that flocculation agent forms the micelle of positively charged in water, their can and water in electronegative micelle attract each other, thereby make electrical neutralization each other and condense.For this reason, require both quantities of electric charge will be about equally.
(3) adsorption bridging effect: some are the high-molecular coagulant adopting of linear structure, and after metal endures the class flocculation agent form linear high polymer in water, all can the strong adsorption colloidal particle.When the particulate of absorption when increasing, above-mentioned thread-like molecule can be crooked, distortion and becomes net, thereby play the effect of bridge formation, distance between particulate is shortened and bonds mutually, forms thick flocs unit gradually.
This flocculation agent has characteristics such as the preparation method is simple, nontoxic, consumption is few, raw material sources are extensive, be suitable for pH value a wider range and flocculating effect is good, medicament expense is low, and whole water treatment procedure is no more than one minute, has improved water treatment efficiency greatly.
Coarse filtration conservancy trash machine: adopt filtration unit cheaply, leach the floss and the water-fast large particulate matter that produce in the flocculation pipeline.
The smart filtration: the core technology of automatic cleaning strainer is a filter screen, and it has changed traditional filter structure, and filter screen is made the oblique net that tilts to rotate along filter cylinder, utilizes the scraper in the net to produce shearing force with the angle that oblique net forms again.Like this, whatsoever the dirt of type under the effect of shearing force, all can or not sticked on the net wall by chopping; Simultaneously, DA-W type automatic cleaning strainer at the another side of net inner cutter, also is provided with a brush in order to reach better cleaning performance, and along with the rotation of cutting knife, the residual spot that brush also will stick on the inwall is simultaneously cleaned out.
Can on the net wall, produce oil film when filtering oily liquid and stop up the problem of filter screen, on the scraper of automatic cleaning strainer, design a backwash device in order to solve.The principle of work of backwash device is: design a sewage draining exit again in the bottom of strainer, it communicates with the backwash device; And there is a Mgs to control at sewage draining exit.When sensor detecting when mesh is stopped up by oil stain, when starting the scraper rotation, the control valve of sewage draining exit is pressed the program behavior that setting means is carried out open closed, when the moment that control valve is opened, the pressure of pipeline is greater than the pressure of sewage draining exit, produce pressure difference, produce back suction power in the part of backwash device, thereby the oil film on the filter screen is sucked sewage draining exit.
Another design of automatic cleaning strainer is that its filter screen is not to make with dull and stereotyped, because the dull and stereotyped filter screen of making can increase the chance that dirt stops up filter screen, so each root of the filter screen of automatic cleaning strainer all is leg-of-mutton; Its inwall is level and smooth, help the cleaning of scraper and brush, and outer net is an opening triangular in shape, and the dirt that therefore is less than or equal to the filtering accuracy requirement can not be stuck on the filter screen, makes strainer remain good working order.
Another characteristics that automatic cleaning strainer is different from other automatic cleaning strainer are, control center of exterior design at machine, the user can be according to the variation that is filtered liquid (often changing as foreign material content), by switchboard the cleaning process of filter interior is adjusted, thereby guarantee that washing unit can rational and effective clean filter screen, really accomplish initiatively to clean.
The belt filter pressing dehydrator: the belt filter pressing dehydrator is to carry sludge blanket secretly by the strainer of two tensionings up and down, S-shaped process from the roll-in tube of a succession of regular arrangement, the tension force of dependence strainer itself forms squeezing and the shearing force to sludge blanket, capillary water in the sludge blanket is pushed out, obtain the higher mud cake of solid content, thereby realize sludge dewatering.
Sterilizing agent throwing device: be used for killing water bacterium, intestinal bacteria etc., guarantee that effluent quality reaches miscellaneous domestic water quality standard.At present, the domestic apparatus and method for that is used for water sterilization is a lot, as: chlorine dioxide generator, ozonizer, chlorine tablets do speculate, chlorine liquid is wet speculates etc.Sterilizing agent can adopt chlorine bleach liquor, solid chlorine tablets, Babysafe etc.
Water quality adjusting system: because wastewater flow rate and enter the ununiformity of impurity in the discharge of wastewater process, making flow, concentration and the temperature of waste water has variation in a big way in round the clock.For guaranteeing water conditioning system works better, be not subjected to the influence of waste water peak flow or change in concentration, so utilize regulating tank to come regulating pondage and water quality.In addition, waste water can neutralize in regulating tank and the sewage of discharging is carried out pre-treatment.
