Description
Technical field
The utility model belongs to a kind of water purification technology, specifically relates to a kind of cleaning treatment system of tap water.
Background technology
Very serious in pollution of waterhead, source quality is very complicated, and Freshwater resources very deficient today, and reverse osmosis desalination technology is undoubtedly the inexorable trend of drinking water treatment.But the use of Reverse Osmosis Water Treatment Technology is subjected to certain restriction because of complicated pretreatment technology and energy consumption problem.The pre-treatment of reverse osmosis system is to influence one of key factor of safe and stable arrangement operation and reverse osmosis economy.Its objective is in order to slow down reverse osmosis membrane and pollute.Conventional reverse osmosis pretreatment process is to adopt more medium filter, activated carbon sterili-sation unit and safety cut-out to carry out pre-treatment, or adds the pretreatment process of reactor and settling vessel before more medium filter.But conventional pretreatment process has complex process, shortcomings such as water quality instability.For overcoming the deficiency that traditional pre-treatment exists, embrane method technology such as micro-filtration, ultrafiltration, nanofiltration are widely adopted in the reverse osmosis pre-treatment in recent years.But there is the deficiency of two aspects in these pretreatment processs: 1) there is membrane pollution problem in the film that is adopted under the stressed outside effect; 2) it is big to handle required energy consumption.It is low to lack energy consumption at present, good processed water quality, simple reverse osmosis pretreatment technology of technology and system thereof.In addition since existing reverse osmosis pretreatment process exist not enough, make reverse osmosis membrane in use exist film to pollute and work-ing life problem such as weak point.
Summary of the invention
The purpose of this utility model is to overcome the complex process that above-mentioned conventional reverse osmosis drinking water treatment technology exists, pre-treatment water quality instability, film is seriously polluted, film is short work-ing life, and defectives such as energy consumption height, thus provide a kind of technology simple, and energy consumption is low, can prevent effectively that reverse osmosis membrane from polluting, and prolongs the drink water purifying treatment system in the life-span of reverse osmosis membrane.
The purpose of this utility model realizes by the following technical solutions:
The utility model provides a kind of cleaning treatment system of tap water, and prepare unit, detection and measurement control unit and supercharging and storage element by pre-filtration units, osmotic treated unit, reverse-osmosis treated unit, disinfection unit, salt solution and form, wherein:
The water side of described pre-filtration units connects the osmotic treated unit by pipeline;
Described permeation unit water side is connected with the feed-water end of reverse osmosis units with pipeline by pump;
The strong brine water side of described reverse osmosis units is connected with permeation unit by a pipeline; The pure water outlet of reverse osmosis units connects disinfection unit;

Salt solution preparation unit connects the unitary opposite side of osmotic treated by pipeline, and detection and measurement control unit are prepared between unit and the osmotic treated unit with water side, the salt solution of pre-filtration units respectively and be connected by signal wire.
The principle of the treatment process that the utility model provides is as follows:
There is corresponding osmotic pressure in the aqueous solution with certain solute concentration, and high concentration solution's osmotic pressure is greater than the osmotic pressure of lower concentration.When the concentration of aqueous solution of permeable membrane both sides is unequal, sees through film by low concentration aqueous solution's one side and enter the water molecules quantity of high concentration solution's one side greater than seeing through the water molecules quantity that film enters low concentration aqueous solution's one side by high concentration solution's one side.Total effect is that the water molecules among the low concentration aqueous solution sees through the side that permeable membrane enters the high concentration solution under the effect of permeable membrane both sides permeable pressure head.The NaCl solution that utilizes the preparation of this principle to have certain salinity places a side of permeation unit permeable membrane with a certain amount of this NaCl solution, makes the osmotic pressure of NaCl solution be higher than the osmotic pressure of former water.In permeation unit, because the osmotic pressure of NaCl solution is higher than the osmotic pressure of former water, water molecules in the former water flows into NaCl solution one side by former water side through permeable membrane under the effect of permeable pressure head, realize the water molecules in the former water (seawater or fresh water) is extracted this purpose.Because this process of osmosis spontaneous generation, so do not need external pressure and heat energy, energy consumption is extremely low.NaCl recycles in the cleaning treatment system of tap water as circulatory mediator.
Advantage of the present utility model is:
(1) use range is wide, and this drinking water treatment system can be used for the purification of sea water desaltination and fresh water;
(2) this drinking water treatment system mainly is made up of osmotic treated and reverse-osmosis treated, and is simple and compact for structure;
(3) unit for treating water before the reverse-osmosis treated unit does not need external pressure and heat energy, and by the variation of phase, energy consumption is extremely not low;
(4) water quality of this drinking water treatment system handles acquisition is good and stable.
