A2/O Process
Containerized Sewage Treatment Equipment adopts A2/O process, which ensures the removal effect of COD, ammonia nitrogen, total nitrogen and also strengthens the removal effect of phosphorus.Containerized Sewage Treatment Equipmentadopts biofilm process, where microorganisms mainly grow on spherical fillers, which can achieve the separation of hydraulic retention time and sludge retention time, and help to enrich the specialized functional microorganisms which have a long generation time and a good treatment effect, and the biofilm is microbial aggregation with certain thickness, and compared with activated sludge method, biofilm method is more resistant to shock load and the operation of the equipment is more stable. Containerized Sewage Treatment Equipment adopts the design concept of low volumetric loading, and the hydraulic retention time is more than 24 hours, which helps to increase the microbial self-oxidizing ability, and improves the quality of the effluent while reducing the production of residual sludge, and reduces the cost of sludge treatment and the cost of construction of sludge tanks. SMC sewage treatment tank is simple and unmanned operation, the use of Internet of Things technology can realize remote mobile management to save operation and maintenance labor costs.
A²O Process Schematic Diagram
(1) Anaerobic, anoxic, and aerobic, the combination of three different environmental conditions and microbial communities are capable of simultaneously removing organic matter and nitrogen and phosphorus.
(2) In the process of simultaneous deoxygenation, phosphorus removal, and organic matter removal, this process flow is the simplest, and the total hydraulic retention time is also less than other similar processes.
(3) Under the alternating environmental of anaerobic, anoxic and aerobic, filamentous bacteria do not reproduce in large numbers, and the SVI is generally less than 100, so sludge expansion does not occur.
(4) The phosphorus content in sludge is high, generally above 2.5%.
