Description
Technical field
The present invention is a kind of microbe carrier of core shell structure and the method for the formula pollution administration water body that drifts along, and belongs to sewage
The technical field of bioengineering of processing.
Background technique
The biological treatment of sewage is the natural process of a microbial life process, is thrown compared to physics and chemical treatment method
Money is few, and low energy consumption.
Sewage Biological Treatment be generally divided into aerobic microbiological processing and the raw speck processing of anaerobism and, these two types of microbe survivals
Oxygen environment requirement completely contradict, while each having irreplaceable biochemical reaction advantage.In order to give full play to
The different advantage of two classes biology, sewage is usually separated undergo " anaerobism " and " aerobic " this twice work respectively in timing and space
Sequence is biodegradable efficiently thorough in the hope of sewage treatment.
Because of the difference of aerobic/anaerobic microbe survival condition and incompatible, two kinds of bioprocess reactions are being carried out
When transition and conversion, need respectively in time or spatially to carry out environment the condition segmentation conversion of aerobic/anaerobic, it is then right
The conversion that flora carries out aerobic/anaerobic flora is cultivated again, this will all occupy and consume plenty of time and place, is caused at sewage
It manages biological method and promotes and applies the low rate bottleneck that time-consuming takes up a large area, seriously constrain pushing away for dirty water living creature processing technique
Wide application.
Water body in nature, especially impounded body, no matter natural or artificial water body, especially eutrophy
Anoxic is presented from bottom to oxygen-enriched water layer, certainly since water surface connects naturally from bottom to top for seriously polluted water body
Touch the high atmosphere of oxygen content and be in oxygen-enriched state, and bottom biological activity oxygen depleted and be in anaerobic condition.
By water body above and below manual agitation, this aerobic/anaerobic micropopulation alternating action may be implemented, but device is high
Expensive and energy consumption.
Aerobic/anaerobic organism must be set in relatively existing Sewage Biological Treatment on space or timing and react incompatible
The technical vulnerability of macro environment, the invention proposes a kind of technical methods of micro that setting aerobic/anaerobic is compatible, pass through
Anaerobic bacteria production gas floats automatically and the oxygen-enriched nitrogen release of the water surface is sunk, and that carrys out high-efficiency low energy consumption handles sewage using biological respinse
New departure.
Summary of the invention
The object of the present invention is to provide the sides of a kind of microbe carrier of core shell structure and the formula pollution administration water body that drifts along
Method, is floated automatically by anaerobic bacteria production gas and the oxygen-enriched nitrogen release of the water surface is sunk, and carrys out utilizing at biological respinse for high-efficiency low energy consumption
