WCBx-20C Seires Biochemical Domestic Sewage Treatment Plant

The method of combining catalytic oxidation, the MBR membrane biological treatment and physical

disinfection sterilization is adopted in the WCBx-C series domestic sewage treatment device; it treats the domestic

sewage of kitchens, W.C., and base room from ship. Since filler is set in the aeration chamber, the chlorine adding

sterilization is adopted, so compare with the products of the same kind, it has the characteristics o f small cubage,

light weight, compact structure and without secondary pollution. The discharged water after the treatment of the

device has reached the effluent standard stipulated internationally, and it accords with the requirement of Resolution

MEPC.227(64) of International Marine Organization Environmental Protection Commission, and International

waste fluid effluent standard.
