Description

Water plant and shaft-like activated carbon microbial inoculum combined purifying method
Technical field
The present invention relates to a kind of sewage water treatment method, particularly relate to water plant and combine only with shaft-like activated carbon microbial inoculum Change 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 reduction cost, Reduce sludge quantity, increase water pollutant matter treatment effeciency and carry the water plant of high water contamination treatment effect and shaft-like activated carbon bacterium Agent combined purifying method.
For reaching above-mentioned purpose, technical scheme is as follows:
Water plant and shaft-like activated carbon microbial inoculum combined purifying method, comprise the following steps:
(1) process in pond arrange two or more and for current sequentially through plantation isolation area, set in this plantation isolation area Putting stone, stone is provided above phytoplankton；
(2) microbial inoculum is prepared；Described microbial inoculum includes: starch 45-65 part, shaft-like activated carbon 20-40 part, sodium polyacrylate 1-6 part, work Journey bacterium 1-3 part, tryptone 2-10 part, phytone 1-3 part, sodium chloride 1-2 part, water 200-400 part；Described shaft-like activity The diameter of charcoal is less than 5mm；This microbial inoculum also includes that particle diameter is not more than the sponge structure of 1cm, and the volume of this sponge structure accounts for cumulative volume 30-50%, sponge structure includes carbon sponge；
(3) microbial inoculum is put in the process pond beyond packing area.
Owing to carbon sponge only has oil absorption, not there is water absorption, by changing carbon sponge volume in the present invention, enter And effectively change the density of the present invention, effectively change the buoyancy that microbial inoculum of the present invention is subject in water body.So, by changing carbon sea Continuous volume ratio can effectively change the microbial inoculum of the present invention hoverheight in water body, uses the bacterium of different volumes ratio carbon sponge Agent applies in a treatment tank, can be effectively improved the treatment effect that water pollutes.And it is added into water body corresponding height position Put the process engineering bacteria locating corresponding polluter, the treatment effect that water pollutes can be greatly enhanced.
By above-mentioned setting, also can the sponge structure in this composite bacteria agent capable and shaft-like activated carbon be recycled, cost is more Low.The present invention is more quick to the processing speed of waste water, test proves that and only needs 6h effectively to remove in sanitary sewage The materials such as organic matter, ammonia nitrogen so that it is meet discharging standards, and removal effect is notable.
Further, the preparation method of described microbial inoculum is:
(1) starch, sponge structure, sodium polyacrylate, tryptone, phytone, sodium chloride and water mix homogeneously are carried out High temperature sterilize, is then cooled to less than 30 DEG C and makes platy structure；The thickness of platy structure is identical with the length of shaft-like activated carbon；
(2) shaft-like activated carbon ultraviolet light is carried out sterilizing, then engineering bacteria is joined mix homogeneously in shaft-like activated carbon；
(3) it is blended with uniform and arranged side by side being inserted in platy structure of shaft-like activated carbon of engineering bacteria, platy structure is cut Become bulk, then at a temperature of 25-35 DEG C, put it in inorganic salt liquid culture medium and cultivate more than 1 day.
Preferably, described plantation isolation area is three, is disposed in parallel in process pond.
Further, described microbial inoculum includes: starch 55-58 part, shaft-like activated carbon 28-30 part, sodium polyacrylate 2-3 part, work Journey bacterium 1 part, tryptone 3-5 part, phytone 1-2 part, 1 part of sodium chloride, water 250-260 part.
In order to reach the most quickly wastewater treatment efficiency, described microbial inoculum includes the agent of three kinds of carbon sponge volume contents Type, in these three kinds of dosage forms, the volume of carbon sponge is respectively 5%-10%, 40%-50% and 50%-90% of sponge structure cumulative 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 cost, reduces sludge quantity, increase water pollutant matter treatment effeciency and carry high water contamination treatment effect Etc. advantage.
