(3) graininess composite bacteria agent capable 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 sewage-treating agent of the present invention is subject in water body.So, by changing The volume ratio becoming carbon sponge can effectively change the sewage-treating agent of the present invention hoverheight in water body, uses different volumes ratio The sewage-treating agent of example carbon sponge applies in a treatment tank, can be effectively improved the treatment effect that water pollutes.And add Add the process engineering bacteria of the corresponding polluter in water body corresponding height position, 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 activated carbon be recycled, cost is lower.This Invent the processing speed of waste water more quick, test proves that only need 6h can effectively remove in sanitary sewage organic The material such as matter, ammonia nitrogen so that it is meet discharging standards, and removal effect is notable.
Further, the preparation method of described graininess composite bacteria agent capable is:
(21) starch, sponge structure, activated carbon, sodium polyacrylate, tryptone, phytone, sodium chloride and water are mixed Uniformly carry out high temperature sterilize, be then added in mould be cooled to less than 30 DEG C, make granular formulations;
(22) engineering bacteria is joined mix homogeneously in granular formulations, at a temperature of 25-35 DEG C, then place 1-2d, then will It is put in inorganic salt liquid culture medium and cultivates more than 1 day.
Preferably, described plantation isolation area is three, is disposed in parallel in process pond.
Further, described graininess composite bacteria agent capable includes: starch 55-58 part, activated carbon 28-30 part, sodium polyacrylate 2-3 Part, engineering bacteria 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 graininess composite bacteria agent capable includes three kinds of carbon sponge volumes The dosage form of content, in these three kinds of dosage forms the volume of carbon sponge be respectively sponge structure cumulative volume 5%-10%, 40%-50% and 50%-90%。
Explicitly pointing out as non-in the present invention, described number is weight portion, and percentage ratio is percent by volume.
