Abstract
The utility model relates to a drinking water arsenic removal device based on novel membrane materials, which comprises a water inlet pipe, a pressure pump connected with a water inlet pipe; a membrane component that is an electrostatic spinning chlorinated polyvinyl chloride membrane material layer and connected with the pressure pump via pipes; a flow meter and a pressure meter disposed on the pipeline between the membrane component and the pressure pump; and a concentrated liquid discharge pipe and a permeate discharge pipe connected with the membrane component. The utility model can remove arsenic in water, and can further remove trace suspension and bacteria in water. The utility model has the advantages of no secondary pollution, long service life, good effect, and low cost; and is suitable for various occasions, especially remote areas with high arsenic level.
Description
Technical field
The utility model relates to a kind of appliance for treating drinking water, a kind of specifically Arsenic Contamination in Groundwater district arsenic removing apparatus for drinking water.
Background technology
Existing arsenic removing apparatus for drinking water, adopt medicaments such as in water, adding chemical agent, inorganic mineral, activated alumina, bone black or material to carry out chemical precipitation, redox or ion-exchange absorption arsenic removal more, not only arsenic removal efficient is low, producing water ratio is low, consume material cost height, and have unfavorable factors such as easily causing secondary pollution, material life cycle weak point, remote high arsenic mountain area or rural area use inconvenience.
Summary of the invention
The purpose of this utility model provides a kind of novel drinking water arsenic removing apparatus based on the new membrane material, to overcome above-mentioned unfavorable factor, improves arsenic removal efficient, reduces processing cost.
The purpose of this utility model can be achieved by following process: a kind of arsenic removing apparatus for drinking water of the utility model based on the new membrane material, and it comprises: water inlet pipe; Pressure pump links to each other with water inlet pipe; Membrane module links to each other with pressure pump by pipeline, and this membrane module is an electrostatic spinning chlorinated polyvinyl chloride membrane layers; Flow is taken into account tensimeter, is arranged on the pipeline between membrane module and the pressure pump; And concentrated solution vent pipe and see through the liquid vent pipe and be connected in membrane module.
The mould material that the utility model adopted is made through the high-voltage electrostatic spinning technology by chlorinated polyvinyl chloride, and is fibrous by superfine nano, and micropore is arranged again on the nanofiber, and specific surface area is big, can adsorb, filter a part of suspended substance.Because this mould material is a bear electricity type mould material, according to Donnan balance model mechanism, by means of repelling homo-ion ability, can hold back, remove the arsenic that exists with negatively charged ion.
The utility model can further be removed trace suspension thing in the water, bacterium etc. in removing tap water in the arsenic, non-secondary pollution, and life cycle is long, and is effective, and cost is low, the outlying especially high-As area use of convenient various occasions.
Description of drawings
Fig. 1 is the utility model device synoptic diagram.
1: water inlet pipe 2: pressure pump
3: under meter 4: tensimeter
5: membrane module 6: the concentrated solution vent pipe
7: see through the liquid vent pipe
Embodiment
Below in conjunction with accompanying drawing task complete process of the present utility model is further elaborated: contain the former water of arsenic and enter the pressure pump water sucking mouth, through the laggard inbound traffics meter 3 of pressure pump 2 pressurizations, after under meter 3 meterings, enter membrane module 5 then through water inlet pipe 1.In membrane module 5, exist with anionic form because arsenic is many in the water, and electrostatic spinning nano fiber band negative electricity, belong to bear electricity type mould material, according to the donnan equilibrium principle, the arsenic negatively charged ion is stopped in a side of mould material can not be passed through, and does not have arsenic water and then sees through film, thereby reach the purpose of separating beavy metal arsenic.During filtration, concentrated solution is decided according to technology running condition through 6 dischargings of concentrated solution vent pipe or backflow, and the no arsenic water that sees through film uses for the user after liquid vent pipe 7 is discharged through seeing through.Wherein the operating pressure of tensimeter 4 reaction film assemblies according to the variation of operating pressure, can be adjusted operating parameters such as concentrated solution quantity discharged.
Below by embodiment the utility model is further described.
Embodiment 1
Get underground water (opacity, 1.4 degree; Total hardness is (with CaCO
3), 510mg.L
-1Vitriol, 123.2mg.L
-1Nitrate (in N), 60.2mg.L
-1), directly add Na
2HAsO
4Be mixed with the experiment water sample, arsenic concentration is 5.013mg.L
-1, after the filtration of electrostatic spinning chlorinated polyvinyl chloride mould material, the clearance of arsenic reaches 50-70%.
Embodiment 2
Get underground water (with embodiment 1), directly add Na
2HAsO
4Be mixed with the experiment water sample, arsenic concentration is 0.10mg.L
-1, after the filtration of electrostatic spinning chlorinated polyvinyl chloride mould material, the concentration of water outlet arsenic is 0.03mg.L
-1, clearance reaches 70%, and the concentration of arsenic is lower than national drinking water standard (0.05mg.L
-1).
Advantage of the present utility model: adopt electronegative micro/nano fibrous membrane material as filtering material, Need not to add chemical agent, use simply, the clearance height of arsenic, when removing Arsenic in Drinking Water, Can further remove trace suspension thing in the water, bacterium etc., non-secondary pollution, life cycle is long, Effective, cost is low, and convenient various occasions particularly outlying high-As area are used.
