Fully Automatic A/O Domestic Sewage Treatment System for School Campus

This A/O biological domestic sewage treatment system is professional environmental protection equipment specially designed for school campuses, university dormitory areas, teaching areas and campus public living areas. Campus domestic sewage mainly comes from student bathing, washing, canteen drainage and daily domestic water, containing a large amount of organic matter, suspended solids, nitrogen and phosphorus substances.

Adopting mature and reliable A/O biochemical treatment technology, this system realizes efficient decomposition and purification of campus sewage. With automatic operation, stable treatment effect and low operating cost, the equipment can effectively solve campus domestic sewage discharge problems and meet environmental protection discharge standards. It is the preferred supporting sewage treatment equipment for new campus construction and old campus environmental renovation projects.

Campus domestic sewage first enters the regulating tank to balance water volume and water quality, reducing the impact of peak sewage discharge on the system.

The sewage flows into the anaerobic tank first to decompose macromolecular organic pollutants and improve sewage biodegradability. Then it enters the anoxic tank and aerobic tank for denitrification, dephosphorization and organic degradation. Through continuous aeration and biochemical reaction, COD, BOD and ammonia nitrogen are effectively removed.

After precipitation and fine filtration, the treated water reaches standard discharge. The system supports automatic sludge reflux and periodic sludge discharge to ensure long-term stable and efficient operation.
