Abstract

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>.

Description

technical field [0001] The invention belongs to a light unfired ceramsite used for wastewater treatment and a preparation method thereof, and belongs to the field of wastewater treatment. Background technique [0002] With the development of industry, heavy metal pollution is becoming more and more serious. The spread of heavy metal wastewater pollution through the food chain will have a profound impact on the environment. Heavy metal wastewater pollution has gradually become a global research topic. [0003] Ceramsite is a relatively cheap product for wastewater treatment, but the existing research on ceramsite is generally prepared by sintering and unfired methods. The development of sintering method is relatively mature, but the process of preparing ceramsite is relatively complicated and the cost is high; while the non-sintering method avoids high-temperature sintering, but it has relatively high requirements for raw materials, and it is not easy to prepare high compress...
