Light-weight non-sintered ceramsite for wastewater treatment and preparation method of light-weight non-sintered ceramsite
The invention discloses light-weight non-sintered ceramsite for wastewater treatment and a preparation method of the light-weight non-sintered ceramsite. According to the preparation method, zeolite powder and coal ash are taken as main raw materials; quicklime, phosphogypsum, Portland cement, ferrous sulfide and aluminum powder are taken as auxiliary ingredients; sodium chloride, attapulgite, sodium silicate, sodium tripolyphosphate, potassiam polyoxyethylene laurylether phosphate, nanometer aluminum oxide and nanometer silicon dioxide are taken as additives. The preparation method comprises the steps of material preparation, mixing, pelletization and forming, and steam curing. The prepared light-weight non-sintered ceramsite has the advantages that the compressive strength is higher than 15 MPa, and the apparent density is lower than 0.9 g/cm<3>.
