The invention relates to the technical field of advanced sewage treatment, in particular to an energy-saving pollution-free marine sewage advanced treatment and recovery device, which comprises a pretreatment tank, an activated carbon adsorption assembly, an RO membrane filtration assembly and a sludge recovery tank; wherein domestic black water is discharged into a black water treatment tank after being subjected to flocculation and sedimentation treatment, and sludge generated by pretreatment is discharged into a sludge recovery tank; the treated water is adsorbed and filtered by the activated carbon adsorption assembly and the RO membrane filtration assembly and then enters a treated water recycling pipeline to be recycled, and the generated sludge enters a sludge recycling tank; the kitchen grey water is subjected to oil-water separation treatment and then enters an independent activated carbon adsorption assembly to be treated, and generated sludge enters a sludge recovery pool; sludge in the sludge recovery pool is crushed by the crushing assembly, then decomposed into toxic and harmful substances by anaerobic bacteria, then enters the leakage cavity, is dried by the heatingpipeline after water is filtered out layer by layer, and is taken out after being dried, so that the sludge is convenient to store and reutilize.
Description
technical field [0001] The invention relates to the technical field of sewage advanced treatment, in particular to an energy-saving and pollution-free marine sewage advanced treatment and recovery device. Background technique [0002] According to the definition of the International Maritime Organization, domestic sewage from ships refers to discharges and other wastes from any type of toilet and urinal; discharges from washbasins, bath tubs and drainage holes in these spaces in medical rooms (pharmacies, wards, etc.); Effluents from spaces containing live animals; or other wastewater mixed with effluents as defined above. "Grey water" refers to drained washing water, kitchen sink water, shower water, laundry water, bath water, and face water, etc. [0003] With the development of the shipping industry, the discharge of domestic sewage from ships has gradually become an important cause of water environment pollution and ecological balance damage. The technical level of my ...
