Description
Technical field
What the present invention relates to is a kind of method of environmental protection technical field, specifically is a kind of method for optimizing stability of aerobic granular sludge.
Background technology
Nitrogen and phosphorus pollution is one of principal element of China's body eutrophication, wherein attaches most importance to ammonia and nitrogen pollution especially: become respectively in densely populated Huaihe River, the Yangtze valley and be ranked first and the 2nd contamination index; And in Taihu Lake of extensively being paid close attention to and Dian Chi, although the permanganate index of most lake surfaces has belonged to III class water, because the nitrogen and phosphorus pollution severe overweight, overall water quality still belongs to V class or even bad V class.The body eutrophication that ammonia and nitrogen pollution inspires causes algae to multiply in a large number, and dissolved oxygen concentration reduces in the water body, and the algae toxin concentration raises, the corrupt smelly situation of hydrobiont mass mortality and even generation, even make whole water body lose due ecological functions.On the other hand, the ammonia nitrogen that enters into natural water body is become nitrate and nitrite by bacterial oxidation easily, also can cause dissolved oxygen concentration decline in the water body, the harm water ecological setting; The nitrate of tap water middle and high concentration and nitrite then can cause baby's methemoglobinemia and nitrosamine type cancer.Therefore, the sewage water denitrification of the tertiary treatment of sewage, particularly city and surrounding area has become control and has improved the key of pollution situation such as China's body eutrophication, and exploiting economy denitrification process efficiently then is the only way of reaching this purpose.
Because there are many shortcomings such as technology is loaded down with trivial details, treatment efficiency is low, running maintenance complexity in existing wastewater biological denitrificaion technology, and the eutrophication pollution that countries in the world face is severe day by day, and the researchist has carried out many effort for this reason and successfully developed novel denitrification process such as SHARON, CANON, ANAMMOX etc.But these technologies all only are effective in the purification of ammonia nitrogen pollutant, also promptly all need to finish organic removing in the waste water in early stage, thereby cause unfavorable situations such as technology is loaded down with trivial details, occupation of land is wide, investment is big, operation and maintenance cost height.The aerobic particle mud technology of Ti Chuing was owing to parameters such as nutrition in the SBR cycle of operation and dissolved oxygen change greatly in the last few years, particularly the microorganism on the different loci is subjected to mass transport affects and faces different nutrition and dissolved oxygen environment in the granule sludge, therefore has the ability of the de-carbon of denitrogenation simultaneously.Does yet this technology lock into its effect main body mark ether handkerchief N peaceful of spraining? cultivate that acclimation period is long, operation stability is still unsatisfactory) and still fail to be promoted in actual applications.
Find through literature search prior art, Li Xiaomings etc. are in " Bioresource technology " (Biological resources technology, 2009, the Enhanced aerobic sludge granulation in sequencingbatch reactor by Mg that delivers on 100:64-67)
2+Augmentation (strengthening granular sludge in the batch type aerobic particle sludge reactor by adding magnesium ion) mentions the magnesium ion that adds 10mg/L in the batch type aerobic particle sludge reactor and can accelerate the granular sludge process, but fails effectively to improve the stability of granule sludge.China's application number is that the rare earth element solution of having put down in writing in 200610069502.5 the patent application by regularly add 30mg/L in the batch type aerobic particle sludge reactor promotes the method that granule sludge forms, same not mentioned influence to granule sludge stability.
Summary of the invention
The present invention is directed to the prior art above shortcomings, a kind of method for optimizing stability of aerobic granular sludge is provided, by in the batch type aerobic particle sludge reactor, adding functional filamentous fungus flora, can shorten granule sludge and form the required time, and can significantly improve concentration, density, subsidence rate and the metabolic activity of mud in the system, make in the time of work simplification that effluent quality obviously improves.
The present invention is achieved by the following technical solutions, the present invention includes following steps:
