Abstract

The invention provides magnetic packing based on waste plastic and a preparation method of the magnetic packing. The preparation method comprises the following steps: preparing a plastic substrate, magnetic ferrite powder and magnetic stripy bodies in sequence, so as to obtain the magnetic packing based on waste plastic finally. The magnetic packing consists of two parts, namely the plastic substrate and the magnetic stripy bodies, wherein the plastic substrate is waste plastic in solid wastes; the magnetic stripy bodies are prepared by wrapping magnetic ferrite powder by using plastic films; the magnetic stripy bodies are inserted into holes in the plastic substrate in a penetration manner; two ends of the magnetic stripy bodies are knotted in the through hole positions; the knots are greater than the holes in size. By adopting the magnetic packing, reutilization of the solid waste is achieved, the environment pollution is alleviated, and a novel idea is provided for treatment on waste plastic and magnetic ferrite powder; the magnetic stripy bodies on the surface of the magnetic packing have a magnetic catalysis function on microorganisms, so that the activity of the microorganisms inside a bioreactor is improved, the pollution degradation property of the microorganisms and the degradation efficiency of the bioreactor are improved, and the biological filming effect is good.

Description

technical field [0001] The invention relates to a magnetic filler based on waste plastics and a preparation method thereof, belonging to the technical field of water treatment. Background technique [0002] With the rapid development of the economy, the production and usage of plastics are increasing. Plastics are easy to age and have a short service life. A large number of plastic products, especially packaging, are discarded after 6-12 months, and some become waste plastics after 1-2 years. As a result, waste plastics are increasing day by day. Waste plastics are often resistant to corrosion and difficult to decompose. If they are not handled properly, they will not only have a great impact on the landscape and ecosystem, but even endanger human health. The resource utilization of waste plastics can not only protect the environment, but also turn waste into treasure and save resources. The recycling industry of waste plastics has become an indispensable resource-based e...
