Technical field:
The present invention relates to a kind of method, belong to the environmental pollution treatment technology field with arsenic removal in the utilizing intermittent electric field water.
Background technology:
In recent years, the arsenic contamination in the water body is serious day by day, and it is then more and more urgent to administer arsenic contamination.At present, the method for improvement arsenic contamination mainly contains the precipitator method, ion exchange method, biochemical process etc.Though precipitator method treatment effect is good, needs a large amount of precipitation agents and easily cause secondary pollution.
Threatened by arsenic contamination at present water body, the inventor explores a kind of with arsenic removal method in the utilizing intermittent electric field water through a large amount of research.By literature search, do not see the open report identical with the present invention.
Summary of the invention:
The objective of the invention is to overcome the deficiency of prior art, and a kind of method with arsenic removal in the utilizing intermittent electric field water is provided.
The present invention utilizes iron ion purity height, can very strong affinity be arranged with arsonium ion, can effectively be combined into the characteristics of the extremely low sedimentable matter of solubility, adopt the parallel plate electric field arrangement of conventional ferroelectric pole plate, the anodal iron ion that produces is combined with arsenate in the water by electric field action; In addition, hydroxide radical that water electrolysis produces and iron ion generate the extremely strong colloid of adsorptive power, and arsenate sinks under water after being wrapped and adsorbing.Whole process is under the effect of utilizing intermittent electric field, and the effect that adds the intermittent time makes reaction process more abundant, has shortened action time, reduces power consumption greatly.
The present invention adopts the parallel plate electric field arrangement of ferroelectric pole plate, with the direct current utilizing intermittent electric field arsonium ion in the water is handled, and its parameter is: 10 volts-50 volts of adjustable voltages, 30 seconds-150 seconds action time, 10 seconds-140 seconds intermittent time.
The present invention has that cost is low, quantities is little, easy and simple to handle, efficient, power consumption less, non-secondary pollution; To the not influence of zooplankton, plant and fish, easily big area is administered the advantage of arsenic contamination in the water body.
