Waste water initially enter multi-medium filtering device assembly, suspension and glue in the multi-medium filtering device assembly in preliminary removal waste water
Body, suspension is reduced to below 5mg/L in making the water outlet after filtering；Subsequently into active carbon filter component, in activated carbon mistake
Partial organic substances and the chlorine residue in waste water are removed in filter module, and waste water is decolourized, through active carbon filter component mistake
The suspension in water outlet after filter is less than 0.1mg/L；Then hyperfiltration membrane assembly is entered through the water outlet of active carbon filter component,
Under effect of water pressure, waste water is entered inside milipore filter in hyperfiltration membrane assembly by outside milipore filter, and the particle diameter in waste water is more than
0.01 micron of particulate matter or solute molecule is isolated on milipore filter, and clean water enters in milipore filter hollow pipeline, and defeated
Send and store into ultrafiltration water tank；Clear water point two-way in ultrafiltration water tank：Enter security personnel under feed water by reverse osmosis pumping action all the way to filter
Device, another road through branch line respectively control valve action under enter multi-medium filtering device assembly, active carbon filter component and
Hyperfiltration membrane assembly, for being backwashed to multi-medium filtering device assembly, active carbon filter component and hyperfiltration membrane assembly；Through ensuring public security
Water outlet after filter enters RO reverse osmosis membrane assemblies, and RO reverse osmosis membrane assemblies are used to the salinity in water removal, through RO reverse osmosis membranes
The total salinity of water outlet after component is less than 400mg/L；Enter reuse water tank reuse through the water outlet after RO reverse osmosis membrane assemblies, and in RO
Drawn on the outlet pipeline of reverse osmosis membrane assembly and be partly into reuse water tank reuse, clear water and cleaning agent in water tank is cleaned
Mix, then cleaned water pump and cleaning filter are delivered to hyperfiltration membrane assembly and RO reverse osmosis membrane assemblies respectively, to milipore filter
Effluent recycling after component and the cleaning of RO reverse osmosis membrane assemblies is to cleaning water tank.
9. desalination process according to claim 8, it is characterized in that：The intake pressure of ultrafiltration apparatus<0.2Mpa.
10. desalination process according to claim 8, it is characterized in that：The intake pressure of RO reverse osmosis membrane assemblies<
1.8Mpa。
