Description
Technical field
The present invention relates to the preparation method of a kind of sewage-treating agent, particularly relate to graininess sewage disposal composite bacteria agent capable
Preparation method.
Background technology
Sewage-treating agent as the term suggests need exactly a kind of additive used when sewage disposal, as polyacrylamide,
PAMC, PAMA, nonionic, amphion polyacrylamide, aluminium polychlorid etc. are not
Can use as sewage-treating agent with in purposes.
The method that water processes has a lot, but existing method for treating water has at physical treatment process, method of chemical treatment and biology
Logos.Physical treatment process is simplest water treating method, and it reclaims the undissolved suspension in sewage by physical separation effect
Pollutant, physical treatment process can only process some simple waste water and process, but processes the most incomplete, it is difficult to reach discharge standard；
Method of chemical treatment causes medicine to consume very greatly, sludge quantity is very big；Biological treatment is to be made the pollutant in sewage by microbial metabolism
Dissolving, but the method investment is big, operating cost is high.
Summary of the invention
It is an object of the invention to the problem of the equal existing defects of sewage disposal in prior art that solves, it is provided that reduce medicine and consume into
This, reduce sludge quantity, increase water pollutant matter treatment effeciency and carry high water contamination treatment effect graininess sewage disposal be combined
The preparation method of microbial inoculum.
For reaching above-mentioned purpose, technical scheme is as follows:
The preparation method of graininess sewage disposal composite bacteria agent capable, including the component of following weight portion:

Even carry out high temperature sterilize, be then added in mould be cooled to less than 30 DEG C, make granular formulations；
(2) microbial inoculum is joined mix homogeneously in granular formulations, at a temperature of 25-35 DEG C, then place 1-2d, then by it
Put in inorganic salt liquid culture medium and cultivate more than 1 day；
Wherein, described starch 45-65 part, activated carbon 20-40 part, sodium polyacrylate 1-6 part, microbial inoculum 1-3 part, tryptone 2-10
Part, phytone 1-3 part, sodium chloride 1-2 part, water 200-400 part；The particle diameter of described activated carbon is 20-200 mesh；This sponge
Structure is the granule that particle diameter is not more than 1cm, the volume 30-50% of the total volume of this sponge structure.
Further, described sponge structure includes carbon sponge.Owing to carbon sponge only has oil absorption, not there is water absorption,
And the weight of this carbon sponge is extremely light, by changing carbon sponge volume in the present invention, and then effectively change the density of the present invention,
Effectively change the buoyancy that composite bacteria agent capable of the present invention is subject in water body.So, can be effective by changing the volume ratio of carbon sponge
Change the composite bacteria agent capable of the present invention hoverheight in water body, use the sewage disposal composite bacteria agent capable of different volumes ratio carbon sponge
Apply in a treatment tank, the treatment effect that water pollutes can be effectively improved.And it is added into water body corresponding height position
Locate the process microbial inoculum of corresponding polluter, the treatment effect that water pollutes can be greatly enhanced.
Further, described starch 50-60 part, activated carbon 25-35 part, sodium polyacrylate 1-3 part, microbial inoculum 1-2 part, Trypsin
Peptone 2-8 part, phytone 1-3 part, sodium chloride 1-2 part, water 230-300 part.
Further, described starch 55-58 part, activated carbon 28-30 part, sodium polyacrylate 2-3 part, microbial inoculum 1 part, pancreas egg
White peptone 3-5 part, phytone 1-2 part, 1 part of sodium chloride, water 250-260 part.
Preferably, the volume of described sponge structure 42-45% of the total volume.
Explicitly pointing out as non-in the present invention, described number is weight portion, and percentage ratio is percent by volume.
The present invention compared with prior art, has the following advantages and beneficial effect:
The present invention has reduction medicine consumption cost, reduces sludge quantity, increase water pollutant matter treatment effeciency and propose high water contamination process
The advantages such as effect.
