Abstract
The invention discloses a method of treating city sewage with an anaerobic-aerobic two sections of membrane biological reactor, which relates to a method of treating the sewage, aiming at solving the problem that the method of treating the sewage with the aerobic process and anaerobic process alternately can not utilize the gaseous resource generated in the process of sewage treatment which cause available resource to be wasted. The water treated by the anoxic reactor is pumped into the aerobic reactor and the following data is controlled and maintained: the pH value is 6.5-7.5; the temperature is 22 to 28 DEG C; hydraulic retention time keeps at 5.5-6.5 hours; content of sludge in the sewage is 9.5-10.5g/L and sludge retention time is 100-160d. The invention has the advantages that: energy saving is realized. As the invention can recycle the resource in the process of sewage treatment, the generated energy can be used for generating power and also used as operation power for a reflux pump of sludge concentrated solution in an up-flow anaerobic sludge reactor; thus saving the adding amount of reagent in the aerobic process stage and realizing the good effects of organic pollutants removal, deoxidization and phosphorous removal.
Description
Technical field
The present invention relates to a kind of water treatment method.
Background technology
Although membrane bioreactor is used for many years, and the application of success is arranged also in actual engineering.But the anaerobic membrane bioreactor development is but very slow, basic not application in actual engineering.Along with becoming increasingly conspicuous of energy problem in the world wide, the problem that China energy faces is also more and more urgent and severe.Therefore, country proposes to save energy and reduce the cost, protect the policy of environment, and aspect energy-conserving and environment-protective, emphasis is the exploitation of energy-conserving and environment-protective technology.The anaerobic treatment of sewage can produce the gaseous state energy such as methane and hydrogen, and degraded product often all is a little small-molecule substances simultaneously, and these materials are easy to be utilized by Institute of Micro-biology in follow-up biochemical treatment.And at present in the technology of membrane bioreactor is used, often adopt the in the majority of aerobic membrane bioreactor separately, between or have some anaerobic membrane bioreactor to be handled reports of high concentrated organic wastewater, such as number of patent application is 200410046448.3, open day is on December 14th, 2005, publication number is CN1706758A, name is called the application for a patent for invention of " Alternate aerobic-anaerobic completely mixing active sludge process ", the water treatment method that a kind of aerobic-anaerobic is used alternatingly is disclosed, but the gaseous state energy that this water treatment method can not utilize in the water treatment procedure to be produced makes the utilizable energy source be wasted.
Summary of the invention
The objective of the invention is in order to solve the gaseous state energy that water treatment method that existing aerobic-anaerobic is used alternatingly can not utilize in the water treatment procedure to be produced, the problem that causes the utilizable energy source to be wasted provides a kind of method of anaerobic-aerobic two-stage membrane bioreactor Treating Municipal Sewage.Method of the present invention realizes according to the following steps: one, with intake pump 5 municipal effluent is driven in the upflow type anaerobic sewage sludge reactor 1, the pH value of sewage is 6.2～7.5 in the control upflow type anaerobic sewage sludge reactor 1, temperature is 22～28 ℃, hydraulic detention time (HRT) is 2.5～3.5 hours, sludge retention time (SRT) is 70～120d, the clearance of representing the COD of organic contamination substrate concentration is 65～75%, the water outlet acetic acid concentration is 47～75mg/L, and the gas production rate of methane is 0.4～0.7m
3/ kgCOD.d; Two, will be driven in the anoxic reacter 9 through the water that upflow type anaerobic sewage sludge reactor 1 is handled, control pH value is 6.5～7.3, temperature is 22～28 ℃, hydraulic detention time (HRT) is 2.5～3.5 hours, the content of mud is 9.5～10.4g/L in the sewage, and sludge retention time (SRT) is 96～105d; Three, to be driven in the aerobic reactor 10 through the water that anoxic reacter 9 is handled, control pH value is 6.5～7.5, temperature is 22～28 ℃, hydraulic detention time (HRT) is 5.5～6.5 hours, the content of mud is 9.5～10.5g/L in the sewage, sludge retention time (SRT) is 100～160d, it is more than 96% that the clearance of the COD of organic contamination substrate concentration is represented in check at last, ammonia-N removal rate is more than 93%, the clearance of phosphorus is more than 92%, reach national reuse water standard, get final product handling qualified reuse water extraction in the aerobic reactor 10 with suction pump 15 then.The invention has the beneficial effects as follows: one, save energy.Because the present invention can reclaim the energy in the Treating Municipal Sewage process, the energy that is produced can be used for generating, and as the power of upflow type anaerobic sewage sludge reactor mud concentrated solution reflux pump running.Two, save the dosage of aerobic treatment stage medicament.Because small-molecule substance generations such as acetate are arranged in the upflow type anaerobic sewage sludge reactor, acetate can be used as the needed carbon source of denitrification in the anoxic reacter simultaneously again.Thereby save the dosage of anoxic reacter carbon source, reduce the consumption of medicament.Simultaneously, the part phosphorus in the sewage is removed through denitrification dephosphorization, has also saved needed carbon source of denitrification and the required oxygen-supplying amount of aerobic suction phosphorus.Three, it is good to remove organic pollutant, deoxidation, phosphor-removing effect.Organism part in the municipal effluent is converted into the gaseous state energy, and a part is converted into needed carbon source of anoxic stage, therefore organic clearance height.Nitrogen in the system and phosphorus are removed through the denitrification dephosphorization process, not only save running cost, and treatment effect are good.
