Description
Technical field
The utility model is related to a kind of devices for being used to carry out waste water anaerobism or scarce Aerobic Process for Treatment, belong to Wastewater Treatment Technology
Art field.
Background technology
In the prior art, anaerobism, anoxic and aerobic reaction are generally used to the processing of waste water.Anaerobism refers in a kind of non-
The biodegradability of sewage can be changed for releasing phosphorus bacterium in oxidation state, anaerobic reaction.Anoxic is the state of oxidation of hypodactylia oxygen, is lacked
Oxygen reaction is for NO3-N and NO2-N denitrification denitrogenation.It is aerobic to refer to oxygen abundance, it is utilized for aerobic microbiological, it is aerobic
Reaction removes BOD for nitrifying with aerobic activated sludge.It is useless to reach purification for generally use anaerobism, anoxic and aerobic association response
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) are carried out with anaerobism, anoxic and aerobic order.
During A2/O process waste water, need in water containing more organic matter to ensure carbon source, it is less in content of organics
In the case of, which 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 influenced 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 absorbs phosphorus, and when discharging excess sludge, phosphorus is excluded together.
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, there are individual anaerobic reactor, aerobic reactor, anaerobism with it is aerobic compound anti-
