Process specification
1)Improved AO+MBBR process
Improved AO+MBBR process flow chart
This process is one of the most common processes in the purification tank. It has the characteristics of simple process and convenient maintenance. Our company has improved the original process, which is slightly different from the ordinary AO process. Anaerobic-anaerobic-aerobic (A2O) process is mainly composed of grille, sedimentation separation tank, facultative filter bed, anaerobic filter bed, biological filler filter, treatment tank and disinfection tank. After removal of large suspended particulates, floats and sediments by grille interception, domestic sewage flows to sedimentation separation tank for further precipitation, in which supernatant enters facultative oxygen filter biochemical tank, denitrification reaction is carried out by heterotrophic microorganisms to remove NH3-N and degrade organic matter in sewage, and then quantitatively transfers into filler by intermittent transfer pump. In aeration and biofilter, autotrophic aerobic microorganisms degrade organic matter and nitrate ammonia nitrogen in sewage. Nitrite is returned to anaerobic filter bed biochemical tank for biological denitrification treatment. Finally, the treated tank is discharged into disinfection tank. The backwash water of the biofilm filler is returned to the solid-liquid separation tank regularly.
2)improved AO+MBR process
Improved AO+MBR process flow chart
This process is one of the most popular sewage treatment technologies at present. It is a new sewage treatment technology that combines membrane separation technology with biotechnology. It uses membrane separation equipment to intercept activated sludge and macromolecule organic matter in biochemical reaction tank, thus eliminating secondary sedimentation tank. As a result, the concentration of activated sludge is greatly increased. The hydraulic retention time (HRT) and sludge retention time (SRT) can be controlled separately, while the refractory substances are continuously reacted and degraded in the reactor.
Compared with traditional biological treatment methods, membrane-bioreactor technology greatly strengthens the function of bioreactor through membrane separation technology. It has the advantages of high biochemical efficiency, strong resistance to load impact, stable effluent quality, small area, long sludge discharge period and easy to realize automatic control.
3、Large Intelligent Integrated Sewage Treatment Equipment
In view of the centralized residential areas in rural areas and new rural areas, the company has developed large and medium-sized intelligent domestic sewage purification tanks for centralized residence of more than 100 people. Through laying sewage collection pipelines, it has established sewage treatment stations for centralized treatment.
Large-scale intelligent integrated sewage treatment equipment, process selection mainly adopts two types of process: improved AO + MBBR and improved AO + MBR.
