Abstract

The invention discloses a gas dissolution method and device for an electromagnetic strengthening water medium and belongs to the technical field of water resource purification and protection through magnetic fields. The device comprises an air outlet, a screen mesh, a water inlet, a spray header, a reaction bed, a stuffing discharging port, an air inlet, a water outlet and a housing. A direct-current controlled high current is adopted to form a magnetic field where the gas and the water are magnetized at the same time, then the magnetized gas and the magnetized water medium form a 'combination unit' of magnetic attraction through random movement of molecules. The invention also discloses a method which is lower in energy consumption and cost, and can increase the solvability of the paramagnetism gases in the water, such as oxygen, ozone and the like.

Description

technical field [0001] The invention discloses a method and a device for electromagnetically strengthening gas dissolution in a water body medium, and belongs to the technical field of purifying and protecting water resources by using a magnetic field. Background technique [0002] As people pay more and more attention to environmental protection, relevant laws and regulations are gradually improved, and the requirements for water treatment are becoming more and more stringent. In today's water treatment methods, whether it is activated sludge or some advanced oxidation technologies, it is necessary to The gas dissolved in the water body is used to carry out the process, and the biggest problem currently facing is the incomplete dissolution of the gas and the problem of gas escape. The solubility of any gas in the water body has a saturation in a given state. Value, we use and consume the gas dissolved in water for chemical reactions will consume the concentration of these g...
