Description

Sewage treatment plant a dopts physical and chemical method to treat ship's domestic sewage.The sturcture type and technical performance of this device is designed and manufacture according to GJB2957-97 Marine sewage treatment system general specification. While satisfy the requirement of IMO resolution MEPC.159(55).This device has characteristics of small size,light weight and compact structure, especially suitable for small installation space room.

Sewage treatment plant is operated in a full automatic control way and set up with alarm device. When the sewage load in the tank is to show anomalous high water, the alarm device will have alarm signal. This device is passive contact and can provide remote alarm signal.

The water discharging for this device meets the IMO standard. The water discharge meets the international stipulated discharging standard , and accords with the request of MEPC159(55) resolution of international maritime organization on environmental committe and international waste liquid discharge standard. The device flushing water is applicable to clean seawater and fresh water.

Principle
First the sewage is input into the treatment tank by the way of nature inflow. When the sewage in the tank up to the middle level, the device begins in process operation, and the working time controlled by PLC. At the time sewage with solid residue is repeated rush by crushing pump in the tank, till the residue can pass the net. At the same time, the washing water constantly flushes the net in order to prevent the solid residue from being accumulated on the net and blocking the net. And through the filter treated sewage from the flow pump life into a series of setting tank. In the setting tank to slow down in , sinking of suspended solids in sewage. Settlement of the sludge from the sludge return pump to send back to cabinet from processing crushed recycling process. The treat sewage settling tank in a series of gradually clarified, when the drawer of a clear liquid to the neutral position, pump work. After the precipitation of liquid container delivered to emissions ,until the setting tank until water level reaches low, pump automatically stop working. When the clean liquid discharge cabinet to high level, discharge pump work ,clean liquid treated by UV disinfection unit to overboard discharge, emissions unit water level reaches low counter. Discharge pump automatically stops working. Now begin to discharge backwash cabinet, until the water level of discharge cabinet reach middle level, device start the next stage working.

Marine Sewage Treatment Plant belongs to the key devices for prevention of pollution form ships in seas. 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 wastes from the toilets on vessels and also called “black water”, to meet the effluent standards of IMO. MEPC.159(55), and discharge the effluent overboard .

The device be used in ship vessels and oil platform. The water quality after treatment can reach the national reuse water quality requirements. It is also applicable to treat the galley、shower drainage which is called  “grey water” on condition that the “grey water” is pretreated and there should select a bigger capacity model to match with.

This device has obtained Authorized Patent and Practical new patent, meanwhile has been obtained the Type Approval of CCS and IMO circular in April 2009, and it in February 2011 by German- Lloyd (GL) type approval certificate MED made, while providing ABS, DNV, BV, RS and other classification societies certificate.

Principle Description
This device adopts the principle of Activated Sludge, Bio-contact Oxidation and Membrane Biological Reactor (MBR) to digest organic pollutant. MBR can treat organic pollutant efficiently, drastically and cleanly to ensure the effluent can meet the requirements of resolution MEPC.159 (55) and other much hasher requirements.
Specification
 1、Adopting horizontal circular design, ellipse closures on both ends, pressure resistance and compact structure.
 2、The device is adopted auto-control and compliance with the requirement of 24-hours unattended cabin.
 3、Adopting the “MBR” technology, devices allow to the narrow size, solve the conflict of small space of cabin, but big volume of device.
 4、The intermittent aeration in bio-membrane tank and hollow fiber membrane tank, form the process of “aerobic – anoxic”,resolve the problem of “nitrogen and phosphorus removal”.
 5、The device adopts the patented technology of the sludge automatic "gas formulation" and the film "s" online "cleaning of the sludge and membrane tanks.
 6、”On-line” cleaning technology, making the dirt on membrane off automatically, recover membrane flux. Solve the problem of open cleaning or replacement of membrane difficultly caused by small space in cabin.
 7、The effluent after further treatment can be reached at the requirement of “water recovery”.
