Description
Technical Field

Background
The activated sludge process is an aerobic biological treatment of sewage, invented and applied by Clark (Clark) and Gage in England in approximately 1913 at the Lawrence sewage test station of Manchester. Nowadays, the activated sludge process and its derivative modified processes are the most widely used methods for treating municipal sewage. It can remove soluble and colloidal biochemical organic substances, suspended solids and other substances adsorbed by activated sludge from sewage, and can also remove a part of phosphorus and nitrogen, and is a general name of various methods for biologically treating microorganisms (micro-organisms) suspended in water by wastewater.
The activated sludge process is a biological waste water treating technology, and is mainly a biological waste water treating process with activated sludge as main component. This technique mixes and agitates the wastewater with activated sludge (microorganisms) and aerates to decompose organic contaminants in the wastewater, and biosolids are then separated from the treated wastewater and optionally partially returned to an aeration tank.
In the activated sludge process, aeration is not separated, wherein aeration is mainly realized by using an aerator which follows a double-membrane theory, and the double-membrane theory is characterized in that gas absorption is a process of transferring an absorbent in a gas phase to a liquid phase through interphase. When gas and liquid contact each other, even if the body of fluid is turbulent, a stable gas stagnation layer (gas film) and a stable liquid stagnation layer (liquid film) are still respectively arranged at two sides of the gas-liquid phase, and in the absorption process, the molecules of the absorbate move from the gas-phase body to the gas film surface, then pass through the gas film in a molecular diffusion mode to reach the gas-liquid two-phase interface, dissolve into the liquid phase on the interface, and then pass through the liquid film from the liquid-phase interface in a molecular diffusion mode to enter the liquid-phase body.
Many present aerators can get into debris in the use, lead to the jam for the treatment effect is not good, and the even degree of aeration also can't satisfy people's demand, and the resistance is great simultaneously.
