METHOD OF ADSORPTION TREATMENT OF WASTE WATERS TO REMOVE PETROLEUM PRODUCTS AND METAL IONS

waste water treatment. SUBSTANCE: adsorbent is prepared by mixing peat, sand, clay or diatomite (20-60%) first with petroleum (10-20%), water, and 3-8% aqueous solution of surfactant (5-10%), and then treated with calcium or magnesium (25-50%), dried, and calcined at 300 to 600 C. Method can be used...

Summary:waste water treatment. SUBSTANCE: adsorbent is prepared by mixing peat, sand, clay or diatomite (20-60%) first with petroleum (10-20%), water, and 3-8% aqueous solution of surfactant (5-10%), and then treated with calcium or magnesium (25-50%), dried, and calcined at 300 to 600 C. Method can be used for treatment of household, process, and surface waste waters from refineries, transport and plating enterprises dealing with petroleum products, lube oils, copper, chromium, lead, iron, and manganese ions. EFFECT: expanded range of recovered substances, simplified and reduced in price waste water treatment technology due use of strong adsorbent with good sorption and filtration properties. 2 dwg, 3 tbl, 5 ex
