Description
Technical field
The present invention relates to a kind of device for being used to carry out waste water anaerobism or scarce Aerobic Process for Treatment, belong to wastewater processing technology neck
Domain.
Background technology
In the prior art, the processing to waste water typically uses anaerobism, anoxic and aerobic reaction.Anaerobism refers in a kind of non-
Oxidation state, anaerobic reaction are used to release phosphorus bacterium, can change the biodegradability of sewage.Anoxic is the state of oxidation of hypodactylia oxygen, is lacked
Oxygen is reacted for NO3-N and NO2-N denitrification denitrogenation.It is aerobic to refer to oxygen abundance, it is available for aerobic microbiological to utilize, it is aerobic
React and remove BOD with aerobic activated sludge for nitrifying.Generally use anaerobism, anoxic and aerobic association response, it is useless to reach purification
The purpose of water.
Following various combinations can be carried out to the anaerobism, anoxic and aerobic reaction of sewage：
1. traditional anaerobism, anoxic and aerobic process (A2/O techniques), carried out with anaerobism, anoxic and aerobic order.
It is less in content of organics during A2/O PROCESS FOR TREATMENT waste water, it is necessary to containing more organic matter to ensure carbon source in water
In the case of, the technique can make denitrification denitrogenation undesirable, and the nitrate nitrogen that returned sludge brings anaerobic zone into makes polyP bacteria release phosphorus not
Fully, the polyP bacteria then influenceed in aerobic zone inhales phosphorus, causes effluent quality unstable, is extremely difficult to good simultaneous denitrification and removes
Phosphorus effect.
2. anaerobism and aerobic combined process (A/O techniques), major function is biological phosphate-eliminating.Anaerobic stages, polyP bacteria release
Phosphorus；Aerobic stage, phosphorus is absorbed, when discharging excess sludge, phosphorus is together excluded.
3. anoxic and aerobic combined process, major function is biological denitrificaion.Anoxic phases, nitrate, nitrite, nitric acid
Nitrogen and cultured water are converted into nitrogen.If ammonia nitrogen in sewage is very high, then by the sewage backflow of aerobic stage to anoxic pond.
In existing sewage disposal device, exist single anaerobic reactor, aerobic reactor, anaerobism with it is aerobic compound anti-
Answer device and scarce aerobic reactor.And anaerobism, anoxic and aerobic process (A2/O techniques) then use the structures of reaction tank more, take up an area
Area is big, and treatment effeciency is low.
But the equipment currently without multiple combinations processing can be carried out to waste water, allow it according to required technique
