Description
Technical field
The utility model relates to a kind of running water pretreatment unit.Especially a kind of running water chlorion removal device.
Background technology
At present, advantages such as the reverse osmosis membrane purification technique is energy-conservation because of having, efficient, easy to operate, be to prepare the water technology that is most widely used in the purified water now, be widely used at industrial departments such as chemical pharmaceutical, electric power, electronics, bioengineering and environmental projects.But because ro components mostly adopts rolling or hollow fibre membrane component, they are very high to the water quality requirement of water inlet, rolling or hollow-fibre membrane reverse osmosis unit are by the standard of international water treatment meeting, the general water inlet pollution index (FI)＜4 that requires, and the former water of the running water that drink in China city is handled owing to the process disinfection by chlorine, and it is too high to contain chlorine residue, meeting oxidative degradation reverse osmosis membrane, do not meet this standard, can not directly take.
For guarantee reverse osmosis unit safe operation and service life thereof, usually want carry out preliminary treatment to the former water of city tap-water earlier, otherwise the membrane component of fragile key or shorten service life of film increases cost.Domestic preconditioning technique to the counter-infiltration water generally adopts the sealing radiator water storage at present, removes impurity in the water by the double medium filtration method of quartz sand filtration+activated carbon filtration.This method cost is than higher, and the effluent quality instability, exceeds standard easily, and operating cost is also high, and effluent quality shields limited to reverse osmosis membrane.At first, because of adopting the disinfection by chlorine sterilization in the municipal tap water, residual chlorine concentration often exceeds standard in the running water, and the free chlorine that is dissolved in the water can suitably volatilize, and adopts sealing radiator just to limit this effect, does not have the chlorine effect of falling.The second, but the impurity in the quartz sand filtration device filtered water, and but because the quartz sand specification of quality that each equipment producer adopts differs, and quartz sand also has certain solubility in water, can increase the salinity in the water to a certain extent, causes electrical conductivity to raise.And the final purpose of reverse osmosis technology is increased water quality exactly, reduces electrical conductivity, this and our final purpose generation contradiction.The 3rd; active carbon filter can adsorb the chlorine residue that can't remove in the prime filtration; go back peculiar smell, colloid and pollutants such as pigment, heavy metal ion, COD and small organic molecule in the adsorbed water simultaneously; but active carbon is to the absorption of chlorine residue; have a problem that absorption is saturated, in a single day the chlorine ion concentration of active carbon filter water outlet reaches 0.1, the active carbon that must more renew; just can reach the purpose of protection reverse osmosis membrane, and the active carbon renewal cost is also than higher.
The utility model content
The purpose of this utility model just be to provide a kind of scientific and reasonable, operating cost is low, the reverse osmosis membrane purified water system pretreatment unit of water quality easy to control.
For reaching the above object, the utility model adopts following technical scheme:
At first the former water of the running water that the city is drunk injects the open type cistern, and reservoir storage is a foundation according to one day water, opens wide and leaves standstill an evening; Handle by one-level active carbon filter and two-stage activated carbon filter successively then, effluent quality can greatly improve, and carries out reverse-osmosis treated by reverse osmosis membrane more at last.
Concrete structure is: the open type cistern links to each other with water pump, and water pump links to each other with the one-level active carbon filter, and the one-level active carbon filter links to each other with two-stage activated carbon filter, and two-stage activated carbon filter links to each other with reverse osmosis membrane.
Described water pump is provided with one or more.
The one-level active carbon filter conforms to the two-stage activated carbon filter specification.
The utility model design science is reasonable; this device can not only be removed the chlorine residue in the running water effectively; reverse osmosis membrane is played the better protect effect; can also prolong the service life of active carbon and reverse osmosis membrane, and treating capacity is big, good stability; operating cost is lower; can reduce the operating cost of water treatment facilities greatly, be applied to the removal of chlorion in preliminary treatment, running water even the waste water of purified water, can create favorable economic benefit and environmental benefit.
The utlity model has following advantage:
(1) design science is reasonable: the utility model adopts open type pond retaining; and the sealing radiator that does not adopt general producer to adopt supplies water; because adopting the open type pond to open wide leaves standstill; chlorine residue can be volatilized fully in the water; greatly reduce chlorine ion concentration in the water; also remove the burden of chlorine residue, thereby prolonged the service life of active carbon, also protected reverse osmosis membrane better for the subsequent treatment operation has alleviated.
(2) technological process is simple and direct efficient: because the quality of quartz sand differs, and the possibility of increase electrical conductivity soluble in water is arranged, thus do not adopt quartz sand filtration, and select for use the firsts and seconds charcoal absorption to filter.The one-level charcoal absorption is filtered both can be with various pollutant adsorption filtrations such as suspension, colloid and pigment, heavy metal ion, COD and small organic molecule in the water, also can reduce the chlorine ion concentration in the water for the first time, alleviate the dechlorination pressure of two-stage activated carbon filter.Filter by the secondary charcoal absorption, the quality of water outlet has very big change, can effectively ensure the stable operation and the service life of reverse osmosis membrane.
(3) environmental protection and energy saving: the old active carbon that one-level active carbon filter filter core generally adopts two-stage activated carbon filter to change gets final product, can reach the purpose of " refuse reclamation ", and the frequency of changing active carbon reduces, and the utilization rate of active carbon also improves greatly, thereby has reduced operating cost.
