Preparation Method, for being purified to water body.
Background technology
PolyP bacteria (PAO) is a kind of special bacterium in conventional activated sludge process, can be incited somebody to action to excess under aerobic state
In phosphorus suction body in sewage, make the several times that in vivo phosphorus content is more than the in vivo phosphorus content of general bacterium, this kind of bacterium is wide
Biological phosphate-eliminating is used for generally.Nitrobacteria (Nitrifying bacteria) is a kind of aerobic bacteria, including nitrous acid
Bacterium and Nitromonas, nitrobacteria have great importance for the cycling conversion of nitrogen in nature, can be oxidized to organic ammonia nitrogen
Cultured water or nitrate nitrogen, are then removed by denitrification, this plays an important role to the removal of Water pollution.It is photosynthetic
Bacterium (Photosynthetic Bacteria) is that occur generally existing in earliest, nature on the earth, there is original luminous energy to close
The prokaryotes of architectonical are the general names for not put the photosynthetic bacterium of oxygen under anaerobic, are that one kind is not formed
The Gram-negative bacteria of gemma ability is using light as the energy, nature can be utilized under anaerobism illumination or aerobic dark condition
In organic matter, sulfide, ammonia etc. carry out photosynthetic microorganism as hydrogen donor and carbon source；Photosynthetic bacteria applies water body
Afterwards, the organic particle in its degradable water body, moreover it is possible to absorb the nuisances such as ammonia, nitrite, the hydrogen sulfide in water body
Matter.Bacillus subtillis（Bacillus subtilis）, be Bacillus one kind, individual cells 0.7~0.8 × 2~3
Micron, uniform coloring, no pod membrane, peritrichous can move, gram-positive bacteria, 0.6~0.9 × 1.0~1.5 microns of gemma,
Ellipse is to column, and central or slightly inclined positioned at thalline, thalline does not expand after sporulation；Bacillus subtilis has very strong cleaning
The short grained effect of rubbish in water has very strong suppression to harmful microorganisms such as vibrios, Escherichia coli and the baculovirals in aquatic products
It makes and uses, additionally it is possible to improve water turbidity problem caused by harmful cyanobacteria is overflowed.These four microbial association uses can play
Go out the purifying water effect of bigger.
Currently, domestic water pollution is increasingly severe, is had attracted much attention using the technology of biological cleaning water body, particularly micro- life
Object water purification microbial inoculum.However, traditional water purification microbial inoculum usually just all releases microorganism putting into the time very short in water
Come, purifying water effect is preferable in a short time, but is difficult to continue to play catharsis.
The content of the invention
The purpose of the present invention is overcome after effect time in existing water purification microbial inoculum input water short, it is difficult to lasting to play purification work
The problem of using.
For this purpose, the present invention provides a kind of compound bacteria microcapsule water purification agent of slow-release, the hair including microcapsules and compound bacteria
