2+The influence of precipitation.
Preparation contains the source water sample that Cd concentration is 1900ug/L, adopts the water sample lab scale of 7 1L, with the best pH value control range of checking except cadmium.By controlling different chemical precipitation ph value of reaction, all add 10% polymeric aluminum chlorides solution of 2ml then, detect supernatant and contain cadmium concentration.Result of the test is as follows:
The water sample numbering | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
Ph value of reaction | 7.85 | 9.36 | 9.84 | 10.08 | 10.29 | 10.52 | 10.72 |
Supernatant cadmium content (ug/L) | 1897.6 | 1488.1 | 685.8 | 204.3 | 198.6 | 91.2 | 301.6 |
Obviously, when the solution pH value was 10.5 left and right sides, the cadmium content in the supernatant was minimum.
In addition, need to prove, except after the ph value of reaction of cadmium controls well, throw aluminium polychloride (PAC) and produce AL (OH)
3Can absorption catch Cd (OH)
2Sediment, the amount of throwing aluminium polychloride (PAC) also has considerable influence to the effect except cadmium.Following content still can draw the optimised quantity that drops into aluminium polychloride (PAC) by experiment.
The preparation pH value is about 10.5, and contains 7 of the water samples that cadmium is 1900ug/L, and result of the test is as follows:
The water sample numbering | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
Throw 10%PAC amount (ml) | 0 | 0.5 | 1 | 1.5 | 2 | 2.5 | 3 |
PH value behind the coagulating | 10.5 | 10.35 | 10.13 | 9.76 | 9.45 | 9.08 | 8.96 |
Supernatant cadmium content (ug/L) | 1886.9 | 1764.7 | 1236.9 | 548.1 | 298.1 | 150.4 | 115.7 |
The result shows: along with the amount of throwing PAC increases, the Cd in the water sample supernatant (OH) 2 effect of settling are obvious.But along with after the amount of throwing PAC in the 1L water sample surpasses 3ml, the supernatant cadmium ion content decline of water sample can slow down.
Therefore, the preferred version of this embodiment, step is added in polymeric aluminum chlorides solution and the active carbon powder, and the concentration of the polymeric aluminum chlorides solution of interpolation is 10%, and the polymeric aluminum chlorides solution that adds and the volume ratio of the 3rd solution are 1: 333.
In addition, add in polymeric aluminum chlorides solution and the active carbon powder in step, the active carbon powder that adds and the mass ratio of the 3rd solution are 1kg: 60T, and active carbon powder preferably adopts 200 purpose active carbon powders, so active carbon can adsorb the most of organic substance in the solution fall, and can effectively wash the DF film, prolong the useful life of DF film.
More than the recovery and treatment method of a kind of cadmium telluride diaphragm solar battery provided by the present invention is described in detail, used specific case herein principle of the present invention and execution mode are set forth, the explanation of above embodiment just is used for helping to understand method of the present invention and core concept thereof.Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention, can also carry out some improvement and modification to the present invention, these improvement and modification also fall in the protection range of claim of the present invention.
