Preferably, bodied ferric sulfate mass fraction is 10~15% in the polymeric ferrous sulphate solution, the swelling
The native and bodied ferric sulfate mass ratio is 1:5.
Further, in the composite treating agent bodied ferric sulfate and the copper industry wastewater quality volume ratio be 10~
30mg/L。
Preferably, bodied ferric sulfate and the copper industry wastewater quality volume ratio are 20mg/ in the composite treating agent
L。
Specifically, the composite treating agent is added to before copper industry waste water the wastewater pH being adjusted to 6~8.
Preferably, the composite treating agent, which is added to before copper industry waste water, is adjusted to 7 for the wastewater pH.
Preferably, the time that is stirred to react is 1~5min.
Preferably, the sedimentation time is 1~5min.
The utility model has the advantages that compound using bentonite and bodied ferric sulfate in the application, the two is shown in can have in the presence of synergistic effect
Effect removes the copper in copper removal industry waste water, and the independent role removal rate compared to bentonite and bodied ferric sulfate is high, reaches discharge standard.

Comparative example 1
Bentonite in embodiment 3 is replaced with etc. to the bodied ferric sulfate of quality, other conditions are the same as embodiment 3.
Comparative example 2
Bodied ferric sulfate in embodiment 3 is replaced with etc. to the bentonite of quality, other conditions are the same as embodiment 3.
Comparative example 3
The bentonite of 3 moderate of embodiment is replaced with to the kaolin of equivalent.Other conditions are the same as embodiment 3.
Comparative example 4
Specific preparation process is as follows for composite treating agent used: taking ferrous sulfate (FeSO4·7H2O) and bentonite, it is being added
Distilled water is stirred, and is uniformly mixed.The concentrated sulfuric acid is added dropwise, 3min is stirred to react after submitting, is then slowly added dropwise 30%
H2O2, after being added dropwise to complete, reaction 1h is stirred at room temperature.After the reaction was completed, it still aging one day, places 15 days, is gathered after concentrated
Closing ferric sulfate/bentonite composite treating agent, (wherein each raw material additional amount guarantees bodied ferric sulfate and bentonite ratio and embodiment 3
In it is roughly the same).
Composite treating agent obtained above is configured to solution according to method in embodiment 3 again, it is useless to be then added to copper industry
In water, actual conditions finally take that treated with embodiment 3., and water is detected.
The detection structure of copper content (wherein copper industry waste water as shown in table 1 below in each embodiment and comparative example processed waste water
Middle copper ion concentration is 18.476mg/L):
Table 1
The composite treating agent that bentonite and bodied ferric sulfate are compounded to form it can be seen from the data in above-mentioned table 1 is to copper
Industry Cu in waste water ion removal rate with higher, treatment effect is much higher than the effect that bentonite, bodied ferric sulfate are individually handled
Fruit；Secondly, it can also be seen that bodied ferric sulfate and other clays carry out compound inorganic agent to the removal effect of Cu in waste water ion
Effect of the fruit also much smaller than bentonite and the compound inorganic agent of bodied ferric sulfate；In addition, in polymerised sulphur in compared with the prior art
The iron standby composite treating agent that bentonite is added in the process and is reacted and is generated of acid, the preparation of the application composite treating agent is simple,
It is with short production cycle and more preferable for the composite treating agent effect of copper ion removal effect the application.
It should be appreciated that described above, the specific embodiments are only for explaining the present invention, is not intended to limit the present invention.By
The obvious changes or variations that spirit of the invention is extended out are still in the protection scope of this invention.
