Background technology
IMO.MEPC.159 (55) resolution that subordinate Marine Environmental Protection Committee of International Maritime Organizaton of United Nations passed through on October 13rd, 2006 has been made brand-new annotation to international anti-pollution convention " MARPOL73/78 "; wherein the index of discharge water makes SS ≯ 35mg/L into by SS ≯ 50mg/L, BOD
5≯ 50mg/L makes BOD into
5≯ 25mg/L, coliform ≯ 250/100ml makes ≯ 100/100ml former no COD into
CrThe discharge index requirement now makes COD into
Cr≯ 125mg/L.Use traditional marine sewage treatment system all can not adapt to such strict emission control standards, can not satisfy the requirement of in the world environmental protection more being paid attention to.
Since 1973 issue international anti-pollution convention, successively employing biochemical process, physico-chemical process, pulverizing sterilization, dilution method, vacuum the two poles of the earth biochemical process, aerobic/many marine sewage treatment systems such as anaerobic process have appearred, still, because:
1, the restriction of marine condition, volume of compartment is very little on the ship, waves, tilts, envrionment conditions such as vibration is abominable, and particularly the narrow and small grade of service clearance causes the difficulty in the device design.
2, international convention is mainly human body removal waste fluid and wash-down water on the ship to the definition of sanitary sewage on the ship, the waste water that comes from the lavatory just, be difficult to handle than it land municipal effluent, particularly on the ship as vacuum toilet is set, more difficult to the waste water that comes from washing water quantity vacuum collection system seldom.
3, new pact makes traditional treatment process too far behind to catch up to the improvement of discharge water index.By land, in recent years because development of auto-control technology, make the technology of the sequence bioreactor radiance of being reset, be exactly no longer to use the plug-flow method, but collection " water inlet-aeration-precipitation-discharging-leisure " is in a cabinet, can save the cupboard volume, this is desirable on ship just, but the peak hydraulic load Special Circumstances that reach on the ship more than three times are difficult to reply.
The embrane method processing is also in the ascendant in recent ten years by land, reaches its maturity.But majority is to be immersed in the bio-reactor, is referred to as Submerged MBR, and condition restriction is difficult to indiscriminately imitate on the ship, therefore, must move to this external solution maintenance, maintenance problem and manage to solve the design requirements of ship rule to the marine low-pressure pressurized vessel.
