[0020] The following examples can make those skilled in the art understand the processing method of the present invention more fully, but do not limit the present invention in any way:
[0021] The process for producing heavy metal wastewater series treatment agents is as follows:
[0022] Add 500 kg of raw silica gel into the corrosion-resistant stirring reaction kettle, and then add 1500 liters of one-equivalent hydrochloric acid or nitric acid from the high-level metering tank; start heating and boiling. The stirring speed is controlled below 60 rpm, so as not to damage the silica gel. Stir and pickle at the bubble point temperature for 6 hours, then pass cooling water to the jacket of the reaction kettle to cool down, and release the silica gel when the temperature of the material in the kettle drops to normal temperature. The released silica gel is filtered out in the filter washer to remove the acid solution, and then the silica gel is washed with deionized water. When ...
