Description

Biological cycle method sewage disposal system
Technical field
The present invention relates to field of environment protection, more particularly, to town domestic sewage treatment technology.
Background technology
On April 3rd, 1914, the young sanitary engineer Edward Ardennes of two, Britain and William Luo Kete are delivered 《Sewage oxidation without filter tank is tested》One text, proposes the concept of " activated sludge ", indicates that activated sludge process is formally absurd fantastic first It is raw.After activated sludge process is born, begin one's study rapidly all over the world, and set about actual construction sewage treatment plant.Nineteen twenty-three, China First wastewater treatment plant using activated sludge process is built up in Shanghai North, and daily handling ability is 3500 cubic metres.Hereafter several years, Shanghai East and West sewage treatment plant also build up in succession, and day output is respectively 1.7 ten thousand steres and 1.5 ten thousand steres.
Today after a century, at least 50000 wastewater treatment plant using activated sludge process are in operation, daily processing all over the world The sewage of at least 5 billion cubic meters.It is no exaggeration to say that, the world without activated sludge process will be difficult to imagine.So, it is living Property sludge be how mankind continuous service a century.
First, this " simple " for being attributable to activated sludge process.One aeration tank, a sedimentation basin, along with backflow, you can group Viability sludge system, completes sewage disposal basic function.It is simple to mean reliable, it is meant that can to popularize, also imply that compared with Low processing cost.Secondly, activated sludge process " powerful " is also major reason.Especially activated sludge process is derived from nature Biotechnology, this is perhaps that it has the basic reason of powerful vitality.
While the huge historical action of activated sludge process certainly, it is necessary to see that it is big in two increasingly highlighted under the new situation Defect:
One is that activated sludge process needs a large amount of power consumptions, is important carbon emission source.According to recent statistics, the sewage disposal in the U.S. The annual kilowatt hour of power consumption 30,200,000,000 altogether in 2011(Only include sewage disposal and regeneration, not including in-situ treatment, sewage collecting and again Unboiled water transmission & distribution), account for the 0.8% of whole society's total electricity consumption then.Japan is as an industrialized country, and sewage disposal power consumption is also accounted for To the 0.8% of the total power consumption of the whole society.The current actual sewage handling rate of China and processing standard are all relatively low, and sewage disposal power consumption is accounted for entirely The ratio of social total power consumption is also relatively low.The high power consumption of sewage disposal, except increase operating cost, also makes important carbon row Put source.
Two be that activated sludge process causes the generation of a large amount of biological sludges.U.S.'s sewage treatment industry produces sludge gross dry weight per year 7500000 tons, Europe produces 10000000 tons per year, and China produces 6000000 tons per year, and total about 30,000,000 tons of the annual production in the whole world is converted to moisture content About 1.5 hundred million tons of 80% dewatered sludge.
The biological sludge that 40% the 60% of these sludge are made up of biomass is living cells constituted with moisture it is special Hydrated structure.Due to large quantity of moisture and organic matter all by " parcel " in the cell, cause dewatering performance of sludge very poor, and be difficult into Row more thoroughly stabilization processes, " burden " as sewage disposal.To improve sludge stabilizing effect, hot water can be used Solution, ultrasonic wave, microwave, the focusing method such as electric pulse and biological enzyme hydrolysis are pre-processed to sludge, make the cell of living cells Wall ruptures, and discharges moisture therein and organic matter, improves dewatering and stable degree, but these Facilities Constructions and runs into This is higher, and that actually builds up is also few.
Activated sludge process realizes that sewage treatment function is that, using high energy consumption as cost, these energy consumptions are used for for microorganism oxygen supply The organic matter in sewage is decomposed, and these organic matters are energy carrier in itself.Therefore, activated sludge process is visually expressed as The technology of " destroying energy with energy ", is also the technology of " emission reduction water pollutant, increasing row greenhouse gases ".
China People University Environment Academy vice-president Wang Hongchen is talked about in " the 8th Environmental Technology forum ":Although active dirty Mud method inertially can also continue to service for the mankind, but we it is reasonable that, it will not persistently turn into the main flow skill of next 100 years Art.
The major function of sewage disposal is organics removal and inorganic nutrient substance, and the former causes black and odorous water, and the latter is then It is the root of eutrophication.50% or so organic matter is resolved into water and carbon dioxide by activated sludge process, and another part is synthesized Biomass, while " destroying energy with energy ", produces a large amount of reluctant biological sludges.
Therefore, people naturally enough wish that sewage disposal is to carry out anaerobism after anaerobism production capacity or separation to organic matter to produce first Can, rather than aerobic oxidation decomposition and synthesis.If organic matter is separated or handled first, it will be left in sewage pending Inorganic nutrient substance.Phos can generally realize efficient removal by biological or chemical process, in the absence of technology barrier, problem master Concentrate on the removal of inorganic nitrogen.Ammonia nitrogen is generally converted into nitrogen by nitrification and denitrification process, and nitrifying process needs A large amount of energy consumptions, therefore people are seeking low energy consumption nitration processes always.In addition, denitrification process needs to consume a large amount of carbon sources, such as Fruit organic matter is separated first, and denitrification can not then be carried out.
If there is low energy consumption and the denitrogenation technology of low-carbon-source demand, great change will occur for sewage disposal process:Using The Anaerobic Treatment of production capacity substitutes the Aerobic Process for Treatment of high energy consumption, first by organic matter removal and recovers energy, and then again by inorganic nitrogen Carry out low energy consumption removal.Discovery, research and the practice of Anammox phenomenon are possible to allow this imagination to come true.
Professor Wang Hongchen represents to think that activated sludge has 3 direction improvement mostly important till now.One is biological Film-activated sludge process(MBBR, IFAS), second is membrane bioreactor(MBR), the 3rd is exactly aerobic particle mud (AGS).These three techniques just inherently greatly improve the efficiency of activated sludge, but we it has to be observed that they not Innovation substantially, they improve efficiency while in various degree add energy consumption.Possible substitute activated sludge Following sewage treatment process is carbon nitrogen two-stage method:First the organic matter in sewage is separated, the sludge isolated is by detesting Oxygen digestion produces methane, or directly carries out Anaerobic Treatment production capacity to sewage, and the sewage containing ammonia nitrogen passes through main flow anaerobism after separation Ammoxidation carries out denitrogenation.By theoretical calculation, using activated sludge process, the pollutant of 1 population equivalent of processing needs the watt-hour of power consumption 44, And above-mentioned carbon nitrogen two-stage method is used, 24 watt-hour energy will be produced by handling the pollutant of 1 population equivalent, so that sewage treatment plant is true Just turn into " energy plant ", and sludge yield is only the 1/4 of activated sludge process.
Terminate at present,《Urban wastewater treatment firm pollutant emission standard》(GB18918-2002)Issue and implement nearly 15 Nian Liao, this standard of 2002 has the possibility substituted by new standard at any time, with the continuous improvement of environmental protection requirement, new mark Brigadier is more strict in old plant.
Therefore, developing a kind of excellent effluent quality, low energy consumption, low-carbon-source, high denitrogenation, the life of sustainable nutrient removal technology Thing round-robin method is that activated sludge innovation of the law substitute technology is imperative.
