The existing problems of an offshore platform electrolytic domestic sewage treatment device were analyzed.Through process calculation,the original tank was used as a biochemical function tank,and MBR treatment unit was added.By adding activated sludge and salt-tolerant bacteria,and after cultivation and domestication,the COD removal rate of the equipment was increased from 58%to 80%,and the effluent COD was stable at about 125 mg/L.It effectively solves the problems of low pollutant removal efficiency of the original equipment and unstable operation of the equipment,and eliminates the hidden dangers of environmental protection existing in the old equipment.
