Abstract
The invention discloses an adsorbent for heavy metal wastewater treatment and a preparation method thereof. The adsorbent comprises 100-200 parts of modified zeolite powder, 50-100 parts of modified attapulgite, 25-75 parts of a hydrophilic modifier, 5-30 parts of sodium bicarbonate, 75-150 parts of aluminosilicate powder and 300-600 parts of water. The preparation method comprises the steps: step1, preparing the modified zeolite powder; step 2, preparation of the modified attapulgite; step 3, carrying out hydrophilic modification on the modified zeolite powder and the modified attapulgite; step 4, preparing an adsorbent core; and step 5, wrapping an adsorbent shell. The adsorbent has the advantages of good hydrophilicity, strong adsorption capacity, low price and easiness in separation from wastewater, and the preparation process and required production equipment are simple and are easy for industrial production.
