Description
Technical field
The invention belongs to water treatment field, particularly a kind of processing system carrying out advanced treatment of wastewater reuse using embrane method
System.
Background technology
Water is the irreplaceable resource that the mankind depend on for existence and development, and is increasingly becoming global economy and society is sustainable
The restraining factors of development.China is the very short country of water resource, is one of 12 Ge Pin lands that abounds in rivers and lakes that the United Nations announces.With warp
The development of Ji, water shortage problem is increasingly severe, and insufficient water brings about great losses to urban industry, causes to resident living simultaneously
Many difficult and inconvenient, the one kind becoming social development hidden is disturbed.The 80% of urban water supply is converted into sewage, after processing through collection,
Wherein 70% can recycle again.By reusing sewage, the available of cities and towns can be made in the case that existing output is constant
The water yield increases by more than 50%.The regeneration of therefore municipal sewage be increase income and decrease expenditure, mitigate water pollution, improve the ecological environment,
Solve one of effective way of urban water shortage.
Conventional sewage disposal technology is after biochemistry etc. is processed, and reaches the water standard of middle water, can be used for city
Greening etc., but for winter, the particularly north, the water yield that greening needs is considerably less, and this part water cannot utilize, or quilt
Discharge wastes, and therefore creates the advanced treating of sewage, and it is many that the water after process can replace new water to meet industrial circulating water etc.
The demand of kind.Adopting reverse osmosis membrane technology the advanced treating of sewage more at present, but reverse osmosis membrane can produce substantial amounts of condensed water, this
Part water salt content is very high, if discharge still can cause water pollution.

The water pump of filter（103）, more medium filter（104）, self-cleaning filter（105）, ultra-filtration membrane device（106）, locate through pre-
Water after reason flows into pretreatment and produces water tank（107）,（Two）Advanced treating part, including booster pump（201）, cartridge filter
（202）, high-pressure pump（203）, reverse osmosis membrane apparatus（204）, reuse water tank（205）, recycle-water supply-water pump（206）.（Three）Concentrated water
Recovery section, including forward osmosis membrane device（301）, draw liquid storage device（302）, draw liquid regenerating unit（303）, draw liquid
Booster pump（304）, dope dehydration and drying processing meanss（305）.Sewage conduct after the simple process such as routine biochemistry, coarse filtration
The raw water of the system is from import（101）Enter raw water storage pool（102）, through water pump（103）Multimedium mistake is sequentially passed through after supercharging
Filter（104）, self-cleaning filter（105）And ultra-filtration membrane device（106）, it is stored in pretreatment through pretreated clear water above
Produce water tank（107）；Clear water produces water tank from pretreatment（107）By booster pump（201）Supercharging, feeds cartridge filter（202）, warp
Cartridge filter（202）Again through high-pressure pump after filtration（203）Boosting, then through reverse osmosis membrane apparatus（204）Advanced treating, reverse osmosis
Permeable membrane device（204）It is divided into two parts water, a part is water purification injection reuse water tank after advanced treating（205）, then through reuse
Water supply-water pump supplies water to user；Reverse osmosis membrane apparatus produce a part of concentrated water and flow into forward osmosis membrane device after processing（301）, warp
Removing a part of water after crossing forward osmosis membrane device becomes dope, enters back into dope dehydration and drying processing meanss（305）, enter and just ooze
Permeable membrane device（301）Also draw liquid, draw liquid and pass through forward osmosis membrane extract water from reverse osmosis concentrated water, drawing liquid is from drawing
Take liquid storage device（302）Through drawing liquid booster pump（304）Feed forward osmosis membrane device, after forward osmosis membrane device
Draw liquor stream and enter to draw liquid regenerating unit（303）, draw liquid regenerating unit and can produce pure water inflow reuse water tank（205）, draw
The liquid that draws that liquid regenerating unit produces is taken to return to and draw liquid storage device（302）.
Present invention application forward osmosis membrane becomes dope with drawing liquid and reverse osmosis concentrated water being concentrated further, more dry through dehydration
Change is processed, and decreases the problem of environmental pollution that condensed water discharge causes, and applies the naturally osmotic principle of forward osmosis membrane from anti-
Water is drawn it is not necessary to apply pressure, not only producing water water quality reaches the mark of pure water for more energy-conservation, therefore the system in infiltration concentrated water
Standard, can replace new Water circulation in the water for industrial use of various high demands, and have energy-conservation, the advantage reducing discharging.
