Preferably, described middle low concentration Bacteria Culture area filling elastic filler.
Preferably, described middle low concentration bacterium is at least one in pseudomonad, bacillus.
Preferably, modified fiber yarn high microsteping obtained in described low concentration Bacteria Culture area block coefficient spinning is filled out
Material.
Preferably, described low concentration bacterium is at least one in nitrifier, pseudomonad, bacillus.
Accompanying drawing 1 is the schematic diagram of multifunctional and composite type microbial bacteria group sewage treatment process.As illustrated, a kind of many work(
Can compound microbial flora fall sewage treatment process, specially cultivate combined many sewage strain classifted training technologies, A areas are highly concentrated
Degree Bacteria Culture area, in B areas concentration Bacteria Culture area, and in C areas low concentration Bacteria Culture area, low concentration Bacteria Culture area of D areas.
Soft-filler is filled in A areas, and easily, Bacteria Culture concentration is high for biofilm（8000-10000mg/L）, bacterial species are few（Substantially
It is some species based on bacterium and fungi）But, measure big 8000-10000mg/L, bacterium can remove highly concentrated in waste water
Degree material；Combined stuffing is filled in B areas, biofilm is easier to, and bacterial species are more, and Bacteria Culture concentration is higher, bacterium
The middle and high concentration material in waste water can be removed；Elastic filler is filled in C areas, biofilm is more difficult, and Bacteria Culture concentration is relatively low,
Bacterium can remove the middle low concentration material in waste water；High microsteping filler is filled in D areas, biofilm is more difficult, easily comes off, only
Having part bacterium can survive, and the Bacteria Culture concentration is relatively low, and bacterium can remove middle low concentration material in waste water and more difficult
The organic matter for the treatment of.
The condition such as cultivation temperature of microorganism is the temperature of suitable micro-organisms growth in the present invention, belongs to the known normal of this area
Know.
Present disclosure is described in further detail below by way of specific embodiment.
Embodiment 1：
For the biochemical treatment of dyeing waste water, it is divided into four regions, as shown in Figure 1.First region（A areas, similarly hereinafter）Using
High concentration microorganism cultivation region, Two Areas（B areas, similarly hereinafter）The concentration Bacteria Culture area in, the 3rd region（C areas, under
Together）The low concentration Bacteria Culture area in, the 4th region（D areas, similarly hereinafter）Using low concentration Bacteria Culture area.High-concentration culturing
Area is high due to concentration, tolerates impact load, can be reasonably resistant to the impact load of raw water, particularly concentration situation higher
Under, effect is particularly evident, and first region microorganism is mainly to vulcanize based on the facultative strain such as bacterium, and the dissolved oxygen in waste water is dense
Degree is decreased obviously, and low to 0.5 ~ 1.0mg/L, concentration of organic wastewater also drastically declines, while sulfide of detection etc. is to micro- life
The index that thing strain has certain toxic action also declines to a great extent herein（Result of the test shows that sulfide index can be from 10mg/L
It is reduced to below 1mg/L）；Two Areas microorganism is mainly based on denitrifying bacterium, the dissolved oxygen in waste water 1.0 ~
Between 1.5mg/L, denitrification is obvious, in four regions, the clearance highest of ammonia nitrogen（Result of the test shows that ammonia nitrogen refers to
Mark can be reduced to below 5mg/L from 50mg/L, and clearance is up to 90%）；3rd region, dissolved oxygen in waste water 1.5 ~
Between 2.0mg/L, this moment, trizonal microorganism fungus kind belongs to conventional bacterial classification（Mainly some bacteriums, such as false unit cell
Bacterium, bacillus etc.）, to the pollutant of waste water（Particularly organic matter）Removal efficiency highest；4th region microorganism is main
Based on nitrifier, common bacteria, the dissolved oxygen of waste water in more than 2.0mg/L, play certainly by the now degraded to trace organic substance
Qualitative effect, such as organic matter.
Embodiment 2：
For the biochemical treatment of the organic wastewater in heavy metal, most of heavy metal has been before four regions are entered, in waste water
Removal.It is divided into four regions, concentration bacterium is trained during first region uses high concentration microorganism cultivation region, Two Areas to use
Foster area, low concentration Bacteria Culture area in the 3rd region use, the 4th region uses low concentration Bacteria Culture area.Micro- life
The strain of thing is same as Example 1.High-concentration culturing area is high due to concentration, tolerates impact load, can be reasonably resistant to raw water
In the case that impact load, particularly concentration are higher, effect is particularly evident, first region, the dissolved oxygen concentration in waste water
It is decreased obviously, low to 0.5 ~ 1.0mg/L, concentration of organic wastewater also drastically declines, while heavy metal of detection etc. is to microorganism
The index that strain has certain toxic action also declines to a great extent herein；Two Areas, dissolved oxygen in waste water 1.0 ~
Between 1.5mg/L, denitrification is obvious, in four regions, the clearance highest of ammonia nitrogen；3rd region, in waste water
Between 1.5 ~ 2.0mg/L, this moment, trizonal microorganism fungus kind belongs to conventional bacterial classification to dissolved oxygen, the pollution to waste water
Thing（Particularly organic matter）Removal efficiency highest；4th region, the dissolved oxygen of waste water in more than 2.0mg/L, now to trace
Decisive role, such as organic matter, ammonia nitrogen index are played in the degraded of organic matter.
