Abstract
The invention discloses a preparation method of magnetic packing. The preparation method comprises the following steps: 3% of magnetic powder, 4% of activated carbon, 2% of starch and 91% of polyvinyl chloride particles are weighed respectively in a weight ratio; the weighed magnetic powder, activated carbon and starch are mixed uniformly; 10% of a wetting dispersant is weighed and added to the 91% of polyvinyl chloride particles and sufficiently mixed; the prepared mixture I of the magnetic powder, the activated carbon and the starch and the prepared mixture II of the wetting dispersant and the polyvinyl chloride particles are mixed sufficiently until a powdery additive is attached to the surfaces of the polyvinyl chloride particles; the prepared mixture is fed into a feeding hopper of an injection molding machine and subjected to extrusion molding through a packing mold; biological packing after injection molding is magnetized on a magnetizing machine, and the modified PVC (polyvinyl chloride) packing is obtained. With adoption of the magnetic packing prepared with the method, the concentration of dissolved oxygen can be increased, enzymatic synthesis can be induced and stimulated, enzyme activity can be maintained, the growth rate of microorganisms can be increased, material metabolism can be promoted, and the biological treatment efficiency of sewage can be increased remarkably.
Description
Technical field
The present invention relates to technical field of sewage, particularly a kind of preparation method of magnetic fillers.
Background technology
The advantage of biomembrance process and pollutants removal rate more high uniqueness comparatively strong to the adaptability of water quality, the water yield because of it, more and more receiving publicity in field of environmental engineering.Biomembrance process is that to be attached to inert support epontic, based on microorganism, has stronger absorption and the structure of biodegradability.There is provided the inert support of attached growth of microorganisms to be referred to as filtrate or filler, therefore, biologic packing material is the core technology in water treatment.
Along with the development of plastics industry, biologic packing material develops into the various plastic fillers of high-ratio surface sum lightweight from the solid filtrate of the low specific surface areas such as rubble, slag and coke.
Biologic packing material is microorganism carrier, closely related with the effect of system cloud gray model.Therefore, selected biologic packing material must meet following characteristic:
1, there is higher specific surface area, for microorganism provides sufficient growing space, be conducive to adhering to higher biomass.
2, there is certain voidage, the turbulent flow of air-flow and current height of formation can be made, strengthen the mass transfer between liquid and gas.
3, there is active surface, surface moist is good and have certain roughness, be easy to microorganism at filling surface apposition growth.
4, there is chemical stability and thermostability, nontoxic, the normal growth of microorganism can not be affected.
5, there is certain physical strength and light weight, wear-resisting, withstand voltage.
6, cheap.
Existing filler can be divided into by material: natural zeolite, gac, polyethylene, polypropylene, urethane and polyvinyl chloride etc., although wherein natural zeolite, active carbon filler have higher surface-area, better absorption property and price is lower, there is the easily defect such as blocking, weak, the aging microbial film difficult drop-off of microorganic adhesion ability; Though common plastic filler easily processing and install, porosity is high, not easily block, not easy to be filmed equally.These shortcomings have had a strong impact on sewage treating efficiency and debugging cycle.
Summary of the invention
The object of the invention is: be starting point from these essential characteristics of filler, create the environment being more conducive to microorganism growth, to improve treatment effect and the efficiency of sewage, therefore the present invention proposes a kind of preparation method of magnetic fillers.
The technical solution adopted for the present invention to solve the technical problems is:
A preparation method for magnetic fillers, comprises the steps:
Step 1: by weight taking 3% magnetic, 4% gac, 2% starch and 91% polyvinyl chloride particles respectively;
Step 2: the magnetic taken, gac and starch are mixed;
Step 3: the Ricinate taking 10% again adds in 91% polyvinyl chloride particles, and fully mixes;
Step 4: mixture obtained with step 3 for mixture obtained for step 2 is fully mixed, to Powdered additive adhesion on the surface of polyvinyl chloride particles;
Step 5: mixture obtained for step 4 is dropped in the loading hopper of injection moulding machine, by filling mould extrusion molding.
Step 6: magnetized on magnet charger by the biologic packing material injected, obtains modified PVC filler.
Further, described step 2,3 and 4 is uniformly mixed all at normal temperatures.
Further, described magnetic, described gac and described starch are all solid powder.
The invention has the beneficial effects as follows: the magnetic fillers adopting the present invention to prepare can increase oxygen in water concentration, induce and excite enzymic synthesis and maintain enzymic activity, accelerate the speed of growth of microbial cells, promote substance metabolism, the biological treatment efficiency of sewage can be significantly improved.
Embodiment
Be below most preferred embodiment of the present invention:
Taking 3kg magnetic, 4kg gac and 2kg starch respectively mixes stand-by, take the polyvinyl chloride particles of 91kg and the Ricinate of 10kg again, and both are fully mixed, add the mixture of stand-by magnetic, gac and starch again, it is made to mix by stirrer, until Powdered additive adhesion is on the surface of polyvinyl chloride particles; Obtained final mixture is dropped in the loading hopper of injection moulding machine, by filling mould extrusion molding; The biologic packing material injected is magnetized on magnet charger, obtains modified PVC filler.
Magnetic in the present invention, gac and starch are all solid powder.
Preparation process of the present invention is all carried out under normal temperature condition, does not also have particular requirement to humidity.
More than show and describe ultimate principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
