Using block carbon sponge as the carrier of complex microorganism, so that obtained water treatment agent had both maintained carbon sponge oil suction and had not inhaled
The characteristic of water, the ability of specific superpower absorption grease and organic solvent, it is close can to absorb 215 ~ 913 times of sole mass of difference
The oil of degree, and absorption efficiency is ultrafast, can significantly remove the grease in biological sewage；Preparation method of the invention is simultaneously using blocky
Carrier of the carbon sponge as complex microorganism so that complex microorganism in the water treatment agent in sanitary sewage it is nitrogenous, contain
Phosphorus and other organic pollutants are degraded in advance, meanwhile, utilize enzyme agent mixed liquor (sodium chloride, lime, the carbonic acid of block carbon sponge
Sodium, chitosan, earthworm fibrinlytic enzyme and water) decompose organic matters such as protein, fat, starch, fiber in sewage, a variety of processing phases
In conjunction with substantially increasing treatment effect (except SS rate, except COD rate and oil removal rate are up to 99%)；Utilize the iron of different size weight
Block (being implanted into it in carbon sponge together before the molding of block carbon sponge) is to change the density of block carbon sponge, and then carbon sponge exists
Buoyancy in water controls the hoverheight (carbon of different densities of the carbon sponge in water body by the iron block of different size weight
It is distributed in different height in the same cesspool of sponge investment and starts simultaneously at progress sewage treatment), effectively improve sanitary sewage disposal
Efficiency reduces medicine consumption；For water treatment agent prepared by the present invention not using the chemical reagent that will appear secondary pollution, majority is natural
Environment-friendly materials, more safety and environmental protection；Carbon sponge is as carrier, on the one hand, it has 99.9% porosity, and adsorptivity is fabulous, separately
On the one hand, it repeats and is recycled after remaining oily substance in the methods of burning removal carbon sponge, reduce cost.
The present invention is described by above-mentioned related embodiment, however above-described embodiment is only to implement example of the invention.
It must be noted that the embodiment disclosed is not limiting as the scope of the present invention.On the contrary, be included in claim spirit and
The modification of range and impartial setting are included in the scope of the present invention.
