Internal-rotation magnetic self-diffusion aggregation type wastewater oil stain adsorption column

Abstract

The invention discloses an internal-rotation magnetic self-diffusion aggregation type wastewater oil stain adsorption column, and belongs to the technical field of wastewater oil stain treatment. In an initial state, fixed magnetic columns and movable magnetic columns are in a homopolar opposite state, and repulsive acting forces exist among a plurality of wastewater oil stain adsorption columns,so that the plurality of wastewater oil stain adsorption columns are automatically far away from each other in wastewater to realize self-diffusion, the wastewater oil stain adsorption columns are distributed on the surface of the wastewater to the maximum extent, and oil stains on the water surface are fully and efficiently absorbed; and along with oil absorption expansion of the oil absorption rubber columns, pricking needles are driven to prick water bags, water is lost, the water bags shrink, and the movable magnetic columns rotate around fixed rods by 180 degrees under the mutual repulsion effect of the fixed magnetic columns and the movable magnetic columns until heteropoles of the movable magnetic columns and the fixed magnetic columns attract each other, and at the moment, the endsaway from each other are the heteropoles, so that the plurality of the wastewater oil stain adsorption columns after oil absorption have a mutual attraction effect and get close to one another to beentangled to realize a self-gathering process, and targeted and rapid fishing and collection are facilitated.

Description

technical field [0001] The invention relates to the technical field of waste water oil pollution treatment, and more specifically relates to an inner-rotation magnetic self-diffusion aggregation type waste water oil pollution adsorption column. Background technique [0002] Oily wastewater comes from a wide variety of sources. In addition to a large amount of oily wastewater discharged from oil extraction and processing industries, there are solid fuel thermal processing, wool washing wastewater in the textile industry, tanning wastewater in light industry, railway and transportation industries, slaughtering and food processing, and turning processes in the machinery industry. Among them, the oily wastewater discharged from the petroleum industry and solid fuel thermal processing industry is the main source. [0003] At present, there are many methods for treating oil pollution in industrial and domestic wastewater, such as mechanical recovery, adsorption, chemical dispersi...

Problems solved by technology

[0004] However, when using the adsorption method to treat waste water, because a large amount of adsorption particles need to be put in, firstly, it is difficult to disperse a large number of adsorption particles evenly on the surface of the wastewater; , it is easy to have a large number of adsorption particles that are salvaged before reaching adsorption saturation, making the utilization rate of adsorption particles low
