Buried Domestic Sewage Treatment Equipment for Water Treatment Projects
Buried domestic sewage treatment equipment uses biological contact oxidation to remove BOD, COD and ammonia nitrogen from domestic sewage.
YAOTONG designs and manufactures customized water treatment equipment based on raw water quality, flow rate, suspended solids concentration, discharge standard and site conditions. This product can be supplied as a standalone unit or integrated into a complete treatment system.
Working Principle
Primary sedimentation > contact oxidation > secondary sedimentation > disinfection > sludge tank > fan room and control
Process flow: Primary sedimentation > contact oxidation > secondary sedimentation > disinfection > sludge tank > fan room and control
