Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage purification device based on a reverse osmosis membrane. Background Art

[0002] Reverse osmosis membrane is an artificial semipermeable membrane with certain characteristics made by simulating biological semipermeable membrane, and is the core component of reverse osmosis technology. Reverse osmosis membrane consists of a 0.1-0.3μm thick cortex (dense layer) and a 100-300μm thick porous support layer. 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 the water. The system has the advantages of good water quality, low energy consumption, no pollution, simple process, and easy operation.

[0003] At present, when a sewage purification device equipped with a reverse osmosis membrane filters sewage, due to the intermittent discharge characteristics of sewage sedimentation treatment, when the valve is continuously opened and closed, the sewage flowing into the sewage purification device will experience rapid changes in flow rate, resulting in a water hammer effect, thereby generating a large pressure in the sewage purification device, and the pressure fluctuates greatly. Sewage with a large flow rate change will damage the reverse osmosis membrane in the sewage purification device, affecting the service life of the reverse osmosis membrane, increasing the cost of equipment use, and failing to guarantee long-term sewage treatment operations. In view of this, we propose a sewage purification device based on a reverse osmosis membrane. Utility Model Content
