Description

Technical Field

[0001] The utility model relates to the field of sewage treatment, in particular to a pressurized reverse osmosis sewage treatment device. Background Art

[0002] Reverse osmosis membrane is an artificial semipermeable membrane with certain characteristics made by simulating biological semipermeable membrane. It is the core component of reverse osmosis technology. The principle of reverse osmosis technology is to separate these substances and water under the action of a pressure higher than the osmotic pressure of the solution, based on the fact that other substances cannot pass through the semipermeable membrane. The pore size of the reverse osmosis membrane is very small, so it can effectively remove dissolved salts, colloids, microorganisms, organic matter, etc. in water.

[0003] The principle of RO reverse osmosis is to separate the solute from the solvent in the solution under a pressure higher than the osmotic pressure of the solution by means of the selective interception effect of the reverse osmosis membrane that only allows water molecules to pass through, thereby achieving the purpose of purifying water or concentrating the solution.

[0004] The working principle of RO reverse osmosis membrane mainly includes the following steps:

[0005] Osmosis: When the same volume of dilute solution and concentrated solution are placed on both sides of a semipermeable membrane, the solvent in the dilute solution naturally passes through the semipermeable membrane and flows spontaneously to the concentrated solution side. This phenomenon is called osmosis.

[0006] Reverse osmosis: When a pressure greater than the osmotic pressure is applied to the concentrated solution side, the flow direction of the solvent will be opposite to the original osmotic direction and begin to flow from the concentrated solution to the dilute solution side. This process is called reverse osmosis.

[0007] Selective permeation: RO reverse osmosis membrane has high permeability to water molecules, and has high retention performance for impurities such as dissolved salts, colloids, organic matter, bacteria, etc. in water, thereby achieving water purification.

[0008] The RO reverse osmosis core material is generally installed inside the membrane shell. When removing the core material inside the membrane shell, it is necessary to use a screwdriver to insert into the water inlet pipe at the top of the core material, and use the lever principle to remove the reverse osmosis core material from the membrane shell. This requires the use of tools, which is time-consuming and labor-intensive. Utility Model Content
