Light-weight ceramsite wastewater treatment method
The invention discloses a light-weight ceramsite wastewater treatment method. Zeolite powder and coal ash are adopted as main raw materials, quick lime, phosphorus gypsum, Portland cement, ferrous sulfide and aluminum powder are adopted as auxiliary components, and sodium chloride, attapulgite, water glass, sodium tripolyphosphate, potassiam polyoxyethylene laurylether phosphate, nanometer aluminium oxide and nanometer silicon dioxide are adopted as additives; the preparation method comprises the steps of material preparing, mixing, pelleting and molding and steam curing; the compressive strength of the prepared light-weight non-sintered ceramsite is greater than 15 Mpa, the apparent density is lower than 0.9 g/cm<3>, and by using the ceramsite wastewater treatment method, the treatment rate of metal ions Pb reaches 99.99%.
