The plant adopts biomcmbranc contact oxidation method and srerilizing principle to digest organic pollutant,It has snitable dimension,compact structure,and weight light,flexible starting and running. The structure type and capability are both complied with National Stapdard GB1083-89<>teqnitement,The discharge wager after treatmcnt also fulfill discharge standard requirement of intcrnational Sea Environment protection Committec IMO MEPC.2(VI),The products may be provided with various marine inspection certificates such as CCS,ZY,BV,ABS,DNV,LR.GL,NK and so on. As strong corrosion resistance,it can use seawater to flush sewage in toilets,It is used in oll kinds of new and old ships or oilrigs. Product adaptation population from 10 people to 100 people. Principle description The sewage from toilets is led into shatter tank,Big suspend solid,after shatteredby pump,is led into two stage aeration tanks through grid, In the two stage aerationtanks, the aerobic bacteria grow on wad and forms biology film- In the condition offilling oxygen, the aerobic bacteria chear up organic subestance in,sewage and changeto innocuous carbon dioxide and water. At the same time, the aerobic bacteria is get tobreed, the organic substance is cleared up again.The treated sewage is led into settletank, the sludge settle to tank bottom is back to aeration tank to as bacteria pip andtreat again The treated sewage is discharged overboard by pump that control by a level control system inthe sterilizing tank.
