WCMBR-(B+G) type shipboard membrane-based domestic sewage treatment device


This device uses a Sequencing Batch Reactor (SBR) membrane process to treat organic pollutants. Wastewater first enters a buffer tank to adapt to biological treatment. This tank can accommodate three times the peak hydraulic load. When the water level in the tank reaches the starting level, it is transferred to an SBR tank with soft packing material for SBR biological contact oxidation treatment. The treated water enters a clear water tank. When a certain water level is reached, it enters the membrane module or is directly discharged. The effluent filtered by the membrane module is disinfected with ozone or ultraviolet light before being discharged overboard, meeting the requirements of IMO MEPC.159(55). This product has obtained CCS type approval certificates, IMO certificates, USCG, ABS and EC certificates, and national invention and utility model patent certificates. In 2008, it was included in the Jiangsu Provincial Science and Technology Achievements Transformation Special Fund Project. Features: It adopts an external membrane, which is convenient for replacement and maintenance; various measures are adopted to extend the service life of the membrane; a buffer tank and standby mode are adopted to meet the requirements of three times the peak load; ozone disinfection or ultraviolet disinfection is adopted to avoid secondary pollution and achieve good decolorization; PLC program control is adopted for more convenient control and maintenance; SBR technology is adopted, with a high sludge load rate, more thorough treatment, and very little sludge discharge; an automatic sleep program is set to adapt to zero-load conditions; multiple treatment methods are set to meet the requirements of different sea areas; this device can also be used to treat concentrated wastewater collected by vacuum. Due to the relatively small hydraulic load, the membrane method is more adaptable.
