Positive penetration sea water desalinization strong brine processing technology and processing system

The invention discloses a positive penetration sea water desalinization strong brine processing technology which comprises the following steps: adopting a positive penetration membrane component, using strong brine obtained by desalting sea water as drawing liquid, using freshwater as charging liquid, discharging the strong brine from the positive penetration membrane component after the strong brine obtained by desalting sea water mixes part of freshwater permeated from a charging side at a permeation side of the positive penetration membrane component and turns into diluted standard-reachingbrine; and discharging residue of the charging liquid from the positive penetration membrane component. The invention also discloses a positive penetration sea water desalinization strong brine processing system which comprises a charging fluid water pump, a positive penetration membrane module, a drawing liquid water pump connected with a transmission side of the positive penetration membrane module, wherein a charging fluid side of the positive penetration membrane module is connected with the charging fluid water pump and provided with a residual charging fluid discharging port, and the transmission side of the positive penetration membrane module is provided with a diluted standard-reaching brine discharging port. The invention can dilute strong brine obtained by desalting sea water to the level of the original sea water, thus avoiding the rising of local sea area salinity when sea water is discharged and protecting marine environment.
