Application

Marine sewage treatment plant belongs to the key devices for prevention of prollution form ships in seas and oceans according to the revised Annex IV of the International Convention of the Prevention of Pollution(MARPOL 73/78).This device is applicable to treat the sewage,which means human body wastes and the wastes from the toilets onvessels and which is also called "black water".

The device also can be used in terrestrial sewage,besides in ship vessels and oil platform.The water quality aftertreatment can reach the national reuse water quality requirements.It's also applicable to treat the galley,showerdrainage which is called"gray water" on condition that the "gray water" is pretreated and these should select a bigger capacity model to match with.

Specification

1.Adoptinghorizontal circular design,ellipse closures on both ends,pressure resistance and compact structure.

2.The device is adoptedauto-control,and compliance with the requirment of24h unattened cabin.

3.Adopting the"MBR" technology,devices allow to the narrow size,and solve the conflict of small space of carbin,but big volume of device.

4.The intermittent aeration in bio-membrane tank and hollow fiber membrane tank,form the process of "aerobic-anoxic",andresolve the problem of "nitrogen and phosphorus removal.

5.The device is adopting the principle of"air-lifting"to transfer the sludge from sediment tank and membrane tank to aeration tank,meantimes the"pump stops and air never stopped",so as the scale on the membrane surface comes dowm.Due to back flushing and clean the membrane "online" usd technol;oge patent.

6."Online" cleaning technology,making the dirt on membrane off automatically,recover membrane flux.It can be solved the problem of openning the cleaning or replacement of the membrane difficultly caused by the small space in cabin.

7.The effluent after further treatment can be reached at the requirment of"water recovery".
