Problems solved by technology

At present, the biological carriers at home and abroad mainly include: ceramics, activated carbon, slag, quartz sand, plastic balls, polystyrene balls and other copolymer materials. High consumption, difficult to remove the film; there is less amount of film hanging, low efficiency of organic matter treatment; slow growth of microorganisms, not easy to fix, low reaction speed, large loss, etc.

Embodiment 1

[0030] A. Mix 120 parts by weight of polyether, 0.3 parts by weight of alkyl tin oxide, and 60 parts by weight of N,N dimethylformamide in proportion. At about 25°C, add 4 parts by weight of isocyanate, add water and stir, and enter foaming stage, add 3 parts by weight of nano-attapulgite to make the water treatment filler have good hydrophilicity;

[0031] B. Stir for 15 minutes, add 1.5 parts by weight of dimethyl silicone oil for defoaming. At this stage, 8 parts by weight of polarized iron powder and 4 parts by weight of modified carbon powder are added to change the internal molecular bonds of the material and enhance the yin and yang of the redox reaction Pole, internally produces compounds with strong adsorption capacity;

[0032] C. After reacting at 25°C for 3 hours, the material is in the coagulation process, and 10 parts by weight of dibutyl hydroxytoluene compound is added to improve the stability and surface activity of the material;

Abstract

The invention relates to a polarization modified biological carrier and a preparation method thereof. The preparation method includes mixing and stirring polyether, alkyltin oxidant, N,N-dimethyl formamide, isocyanate and water according to the proportion; then adding nanometer palygouskite when the mixtures are in the foaming stage; stirring the mixtures for 15 minutes, adding dimethyl silicone oil for defoaming, and blending polarization iron powders and modified iron powders so as to change inner molecular bond of materials, enhance anode and cathode of a redox reaction and produce compounds with a high adsorbing ability in the interior; adding dibutylated hydroxytoluene to increase the stability and surface activity of materials after the mixtures react for 3 hours at a temperature of 25 DEG C when the materials are in the process of condensing; and finally, cutting the condensed materials into blocks after solidifying and molding. According to the polarization modified biological carrier and the preparation method thereof, by means of the polarization modified materials, the surface activity of the biological carrier is greatly improved, and sewage treatment effects are good.

Description

technical field [0001] The invention belongs to the field of environmental protection, and relates to a polarization-modified biological carrier and a preparation method thereof. More specifically, the invention relates to a polarization-modified biological carrier for sewage treatment and a preparation method thereof. Background technique [0002] The increasingly serious water pollution is one of the main problems facing our country's environmental protection. Sewage biochemical treatment technology is the main technology in sewage treatment, and biological carrier is the core of biochemical treatment technology. At present, the biological carriers at home and abroad mainly include: ceramics, activated carbon, slag, quartz sand, plastic balls, polystyrene balls and other copolymer materials. It consumes a lot of money, and it is difficult to remove the film; there is a small amount of film hanging, and the treatment efficiency of organic matter is low; the growth of micro...
