The package sewage treatment plant principle is a kind of biochemical treatment which combine activated sludge microbiological method and new biological membrane manner. In treatment process, large bacteria and bacteria membrane update, adopt biological carrier, improve the contact efficiency of micro- organism and pollutant matter in sewage; the whole treatment equipment produce anaerobic-anoxia- aerobic three kind of environment take turns function, improve purified water ability of different kind of microbial population, intensify organism removal and nitrogen and phosphorus removal function.
Combine our company past success practice, suggest sue biofilm manner treatment process, plan to adopt A/O biological contact oxygen process as main treatment manner. Such process is more mature, has certain history, widely used in textile system factories, such process main device has equalize tank,aeration tank and clarifier etc. equalize tank mainly use to equalize waste water quality and quantity in each pollutant source, prevent form impact to aeration tank, prevent bacteria die. Thus, it will be better of sewage stay long time in equalize tank, but it should consider construction expense.
