Liquid booster pump（304）, dope dehydration and drying processing unit（305）.Sewage after the simple process such as routine biochemistry, coarse filtration by making
It is the raw water of the system from import（101）Into raw water storage pool（102）, through water pump（103）Multimedium is sequentially passed through after supercharging
Filter（104）, self-cleaning filter（105）And ultra-filtration membrane device（106）, pretreated clear water is stored in pre- place more than
Reason produces water tank（107）；Clear water produces water tank from pretreatment（107）By booster pump（201）Supercharging, feeds cartridge filter（202）,
Through cartridge filter（202）Again by high-pressure pump after filtering（203）Boosting, then through reverse osmosis membrane apparatus（204）Advanced treating, instead
Permeable membrane device（204）It is divided into two parts water after advanced treating, a part is water purification injection reuse water tank（205）, then pass through back
Supplied water to user with water supply-water pump；A part of concentrated water is produced to flow into forward osmosis membrane device after reverse osmosis membrane apparatus treatment（301）,
By removing a part of water after forward osmosis membrane device as dope, dope dehydration and drying processing unit is entered back into（305）, into just
Permeable membrane device（301）Also have and draw liquid, draw liquid by forward osmosis membrane extract water from reverse osmosis concentrated water, draw liquid be from
Draw liquid storage device（302）By drawing liquid booster pump（304）Forward osmosis membrane device is fed, by after forward osmosis membrane device
Draw liquid flow into draw liquid regenerating unit（303）, drawing liquid regenerating unit can produce pure water to flow into reuse water tank（205）,
The liquid that draws for drawing the generation of liquid regenerating unit is returned to and draws liquid storage device（302）.
The utility model application forward osmosis membrane turns into dope with liquid concentration further to reverse osmosis concentrated water is drawn, then by de-
Water drying and other treatment, reduces the problem of environmental pollution that condensed water discharge is caused, and using the naturally osmotic principle of forward osmosis membrane
Water is drawn from reverse osmosis concentrated water, it is not necessary to apply pressure, more energy-conservation, thus the system not only producing water water quality reaches pure water
Standard, new Water circulation can be replaced in the industrial water of various demands high, and with energy-conservation, the advantage of emission reduction.
Brief description of the drawings
The structural representation of the embrane method advanced treatment of wastewater reclaiming system that Fig. 1 is provided for the utility model.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment describes the utility model in detail, Fig. 1 provides for the utility model
The structural representation of embrane method advanced treatment of wastewater reclaiming system, as illustrated, the system sewage by routine biochemistry, coarse filtration
Etc. the water after simple process as raw water, including three parts device：（One）Preprocessing part, including sewage is by simple process
Afterwards as the original water inlet of system（101）, raw water storage pool（102）, water lifted to more medium filter from raw water storage pool
Water pump（103）, more medium filter（104）, self-cleaning filter（105）, ultra-filtration membrane device（106）, it is after pretreatment
Water flows into pretreatment and produces water tank（107）,（Two）Advanced treating part, including booster pump（201）, cartridge filter（202）, high pressure
