About the treatment process in sewage treatment

Membrane bioreactor is a new high-efficiency sewage treatment technology that organically combines membrane separation technology with traditional sewage biological treatment technology. It effectively improves the efficiency of mud-water separation through the efficient separation of membrane modules, thereby enabling activated sludge in the aeration tank. Increase in density. Due to the appearance of special-effect bacteria in the sludge, the biochemical reaction rate is greatly improved. This process can greatly reduce the output of residual sludge, which basically solves the large amount of residual sludge existing in traditional biological treatment methods. Problems such as low operating efficiency.


Sewage treatment generally includes the following three stages of treatment: the first stage treatment is to remove the stones, sand and fat, iron ions, manganese ions, grease, etc. contained in the sewage through mechanical treatment, such as grille, sedimentation or air flotation. . Secondary treatment is biological treatment. Pollutants in sewage are degraded and converted into sludge by the action of microorganisms. Tertiary treatment is the advanced treatment of sewage, which includes the removal of nutrients and disinfection of sewage by chlorine, ultraviolet radiation or ozone technology. It is possible that some sewage treatment processes may not include all of the above processes, depending on the treatment objectives and water quality.

Purified water treatment process depends on the quality of the raw water.

If the raw water is municipal tap water, the general process is

Sand filter--Activated carbon filter--Softening (optional)-Security filter--Reverse osmosis--UV disinfection--Production water

For general surface water, sterilize and add flocculants before entering the above process.

If it is well water, add iron and manganese removal filter after sand filtration.

Water is circulated for purification.

Quartz sand filtration is one of the effective methods to remove suspended matter in water. It is an important unit in advanced sewage treatment, sewage reuse and water treatment. Its function is to further remove the pollutants that have flocculated in the water. It achieves the purpose of water purification through the retention, sedimentation and adsorption of filter materials.
