Description

A kind of town sewage high standard denitrification dephosphorization system without additional carbon
Technical field
The present invention relates to a kind of sewage disposal system, is a kind of town sewage high standard denitrogenation dephosphorizing without additional carbon System.
Background technology
With the continuous aggravation of body eutrophication, the denitrogenation dephosphorizing of town sewage receives much concern always.Traditional biology Denitrification dephosphorization technique is widely applied in urban wastewater treatment, but exist energy and material consumption is higher, technological process is longer, In place of the deficiencies of floor space is larger, in the case where sewage carbon-nitrogen ratio is relatively low, it is also necessary to add substantial amounts of external carbon source.Cause This, development and application are efficient, green, the sewage disposal novel process system of low-carbon are as the important of current and future sewage disposal Trend.
As novel biological dinitrification technology, Anammox can be saved significantly compared with traditional denitrification process process Energy consumption, without additional carbon, and sludge yield is small, has broad based growth prospect, by the wide of domestic and international sewage disposal researcher General concern.The technology is under anaerobic, to pass through peculiar microorganism colony, directly using ammonia nitrogen as electron donor, nitrite Nitrogen is final electron acceptor, ammonia nitrogen and nitrite nitrogen is transformed into nitrogen, without providing organic carbon source, you can realizes that biology is de- Nitrogen.
At present, Anammox technical research is concentrated mainly on high temperature industrial waste water with high ammoniac nitrogen with engineer applied or sludge is detested The denitrogenation of oxygen digestive juice, the denitrogenation processing application study for town sewage are also very limited.Urban wastewater treatment amount is big, composition Complexity, influence factor are more, research and develop and are adapted to the prevailing technology Anammox technology of town sewage to have important reality meaning Justice.
Anammox technology, which is used for town sewage, still has many more distinct issues.For example, influent ammonium concentration It is relatively low with water temperature and when substantially fluctuating, nitrobacteria(NOB)Effective suppression and anaerobic ammonia oxidizing bacteria(Anammox)Effectively cut Stay it is more difficult, therefore, it is necessary in certain applicable elements and operational factor when the technology is used for the urban wastewater treatment of normal temperature Under, the denitrification effect of stability and high efficiency could be obtained.In addition, the actual motion clearance and stability of denitrification of anaerobic ammonium oxidation Limited by many factors, it is difficult to directly obtain the effluent quality of low concentration, to obtain the Nitrogen/Phosphorus Removal of high standard, must also Dephosphorization unit and fine denitrogenation unit must be set.Therefore, it is merged and integrated with traditional denitrification dephosphorization technique system, filled The advantages of Anammox techniques save carbon source, the energy are waved in distribution, and conventional art is stable, reliable, can be town sewage, especially It is the efficient low-consume denitrogenation dephosphorizing offer new way of low carbon-nitrogen ratio sewage, and forms new process for removing nitrogen and phosphor from sewage system.
Because organic matter can have a negative impact to autotrophic type anaerobic ammonia oxidizing bacteria, reacted in sewage into Anammox Need to remove it as far as possible before device, but if its direct aerobe is aoxidized, consider from resource reclaim angle and unreasonable.When In the preceding prevailing technology application study of Anammox in the world, it is substantially all and anaerobic sludge digestion and effluent Anammox phase With reference to promote power self-support and carbon to neutralize.It is significantly different with foreign town sewage quality, China's town sewage, particularly south Side area, concentration of wastewater is relatively low, and content of organics is low, inorganic suspended solid ratio is high, and carbon-nitrogen ratio is generally relatively low, to denitrogenation Dephosphorization is very unfavorable, and therefore, the high standard stably reaching standard for handling water outlet should be used as the primary goal of process system, sludge acidifying and Anaerobic digestion is developed as internal carbon source and the important means of mud decrement, takes into account the energy profit of organic matter of sewage on this basis With.
Organic matter and suspended solid are separated in form of a sludge, directly as carbon source, or after everfermentation again It is a kind of warp for recycling " internal carbon source " organic matter during adding to traditional biological denitrification dephosphorization technique as high-quality carbon source Help effective approach.Main component in sludge is carbohydrate, protein, fat and grease, and inherently one kind can quilt The carbon source utilized, ferment under anaerobic can also output great amount of soluble organic matter, the especially VFA of small molecule, It is the high-quality matrix easily utilized by denitrifying bacterium and dephosphorization bacterial., can using sludge or sludge fermentation liquid supplement water-inlet carbon source Biological denitrification dephosphorization efficiency is improved, strengthens the operation stability and reliability of process system.
The content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art, there is provided it is a kind of can effectively remove it is organic in sewage Thing, suspended solid and nitrogen and phosphorus thing, it is easy to accomplish urban wastewater treatment firm stable water outlet is up to standard, reduces energy and material consumption, simultaneously Promote the recycling of sewage and a kind of town sewage high standard denitrification dephosphorization system without additional carbon of recovery energy.
