Description

A kind of anaerobism-oxygen-aerobic integratedization sewage disposal device and method of holding concurrently that comprises reuse

Technical field the invention belongs to sewage disposal, reuse technology field.Be particularly related to and realize anaerobism, double oxygen, aerobic three kinds of biological growth states and have the sewage water denitrification dephosphorization and the novel sewage disposal technology and the equipment of water reuse function.

Background technology is well-known, and shortage of water resources, energy shortage, water are seriously polluted to be three big factors of restriction Chinese national economy development.Shortage of water resources causes discharge water path and underground water source deficiency, thereby it is less to make water system can hold the total amount of pollutent, causes water environment pollution easily; Energy shortage makes us can not adopt the processing efficiency height but the big technology of energy consumption is come decontamination, thereby makes reduction low to the ability that water system discharges pollutants, and the two all is the major reason that is unfavorable for water environment protection.High speed development in the face of Chinese national economy, industrial production and people's lives all inevitably produce water pollutant, water pollutant enters after the water body, at first influence is exactly water resources, environment yearbook statistics according to calendar year 2001 State Environmental Protection Administration's issue, a few large watershed water quality of China allow of no optimist, one, two class water quality are only in 30%, and four, five and surpass five class water quality more than 50%, that is to say that water resources more than 50% will lose use value and maybe need to consume and could obtain after the more energy is handled to use.Certainly, develop new water source, excavate new forms of energy, people are carrying out unremitting effort always, pollute yet eliminate water, and particularly high-efficiency low energy consumption ground is eliminated the water pollution and is not only the vital task of environment protection, and are water resources protection and the great task of effectively utilizing.

At present, in order to solve the pollution problem of China's city domestic sewage, country is utilizing domestic and international all kinds of loan to quicken the construction of municipal sewage plant, and this is not talkative not to be a marvelous grand engineering.But should see not putting into operation fully or reach the designing treatment ability in the municipal sewage plant that China has built up at present, tracing it to its cause no doubt has Environmental awareness problem and policy and handling problem, but what must mention is the problem of technology itself.People at present blindly indiscriminately imitate external ready-made technology, in fact ignored an important fact: external mature technology is the high energy consumption under highly developed economic condition supports, expensive treatment process, its home products is promoted by part foreign vendor in order to take this opportunity at present, all conditions in various loans, have been added, handle like this that not only construction cost is huge, building up the back running cost also is a very big burden.And the water technology that is fit to China's national situation should be a less investment, and working cost is low, and the technology that treatment effect is high is higher than external ready-made technology to the requirement of this technology, needs to drop into bigger manpower, financial resources, material resources and researches and develops.

According to the character of water pollutant and the characteristics in subtractive process, we are divided three classes the pollutent in the sanitary sewage usually: organic carbon pollutant, nitrogen-containing pollutant, contain phosphor contaminant; Corresponding pollutant removing process adopts the biomineralization of organic carbon usually, is about to organic carbon and is transformed into carbonic acid gas, and nitrification and denitrification is about to nitrogenous compound and is transformed into nitrogen, and biological dephosphorization is about to P contained compound and is transformed into insoluble inorganic phosphate precipitation.Since the biological species difference of above-mentioned three processes, the biological characteristics difference, and the processing unit of employing and process are all inequality.People consider the difference of each section biological characteristics the earliest, the treatment process that adopts the many equipment of multistage to control respectively, as: aerobic-aerobic-anaerobism, though this technology is convenient to control, can make microorganism be in the optimum growh state, increased processing cost but need replenish new carbon source during owing to anaerobic denitrifying, invested bigger simultaneously because of treatment process is long; People have developed rearmounted nitration processes again for this reason: anaerobism (denitrification)-aerobic (taking off organic carbon)-aerobic (nitrated)-be back to anaerobism section (partial discharge), original carbon source is as the denitrifying energy in this technology utilization sewage, saved the new carbon source that to add, but reflux one is to have increased power consumption, the 2nd, reduced denitrification percent, because denitrification percent is directly related with recurrence rate, reach 90% denitrification percent and just need 9 times of quantity of reflux, power consumption and volume of equipment all increase greatly, and investment does not reduce according to the set goal with working cost; Implement the shortcoming of above-mentioned three kinds of technological processs in order to overcome the segmentation subset, sequencing batch active sludge SBR technology obtains common concern, it has simplified technological process and equipment, in a single devices, finish above-mentioned three processes by controlling different operating parameterss, but, it has sacrificed the top condition and the stability factor thereof of microorganism growth, in fact make various microorganism growth in a single devices, and the different a certain classes of time chien shih fast growth and in addition several classes be suppressed, alternate run successively, total biology efficient does not reach good order and condition.

Simultaneously in order to realize the continuity of sewage treatment process, have to adopt the cycling service of alternately intaking of a plurality of single devices, its plant factor is lower, floor space and investment strengthen, wherein not reach the optimization state also be to cause volume of equipment load not high to biology, need be than one of large equipment volumetrical major reason.Can realize in a single devices that it is the hot issue that people study that successive takes off organic carbon, denitrogenation, dephosphorization always.

M.Ros and J.Vrtovsek have studied a kind of anaerobic-anoxic-aerobic integratedization sewage disposal device, its main body experimental installation is a cylindrical pad tower reactor, a tower body is because the control of oxygen supply position and quantity of reflux realizes three oxygen characteristic subregions: bottom 1/4 is anaerobism section (void tower), middle part 1/4 is anoxic section (filler is arranged), and top 1/2 is aerobic section (filler is arranged); Sewage enters reactor from the bottom, and at first by anaerobic zone, the sewage after anaerobic zone top has refluxing opening with the part anaerobic treatment turns back to inhalant region; Sewage after the anaerobic treatment then upwards enters into the oxygen-starved area, and realize by the aerobic zone water part being back to the bottom, oxygen-starved area in the source of oxygen-starved area trace dissolved oxygen; Then upwards enter into aerobic zone through the sewage after the processing of oxygen-starved area, the dissolved oxygen of aerobic zone derives from the oxygen supply equipment that is located at the aerobic zone bottom.In this reactor, the bottom is equivalent to UASB, and filler is not set, and relies on anaerobic grain sludge realization acidification hydrolization to deviate from the organic carbon pollutent, and particulate suspends and controls by the quantity of reflux of anaerobism section itself.Anoxic section major function is a denitrification, the micromolecular compound that its carbon source can be produced by the hydrolysis of anaerobism section easily provides, nitrifying process is then finished at aerobic section, is incorporated into the anoxic section by backflow, and its primary process is similar to foregoing forward type biological denitrification process.Though this technology has realized serialization single devices anaerobic-anoxic-aerobic sewage treatment process, but self refluxing of anaerobism section needs power wheel drive, aerobic section is to the backflow of anoxic section also consumption of power, the forward type denitrification is not eliminated the requirement of high reflux ratio simultaneously, and high reflux ratio will bring high-solubility oxygen, and it is stable that the control of anoxic section operating parameters is difficult for.

S.H.Chuang, etc. developed another anaerobic-anoxic-aerobic integratedization sewage disposal device, its main equipment is three troughs adjacent one another are of horizontal positioned, first groove is the anaerobism groove, second groove is the anoxic groove, three-flute is an aerobic slot, sewage enters reactor from the anaerobism groove, and overflow backward successively, anaerobism groove and anoxic groove all are provided with stirring with the reinforcing mass transfer process, and the anaerobism groove is by the air oxygen supply and realize whipping process, aerobic slot also is provided with pneumatic blodisc, to improve processing efficiency, simultaneously, its denitrification process still relies on the aerobic slot effluent recycling to realize to the anoxic groove.This reactor does not fundamentally overcome the defective of previous reaction device, and on the contrary, the stirring of anaerobism and anoxic groove has increased power consumption again, and the denitrification rate is still by quantity of reflux control, and quantity of reflux still exists the influence of dissolved oxygen.
