Bioactive filler applied to water treatment field

Abstract

The invention discloses bioactive filler. The filler is used for water treatment, sewage and waste water treatment. A natural pumice stone is used as the raw material of the filler and is processed into the needed particle shape; the optimum grain density of the filler is 500-800kg / cm<3> and the optimum inflow porosity is 40-50%. Most of all, the filler is especially suitable for a trickling filter, an anaerobic biofilter, a filter, a biological fluidized bed, a biological aerated filter, a high-load biofilter, a tower-type biofilter and an activated biofilter.

Description

technical field [0001] The invention relates to a bioactive filler applied in the field of water treatment. Background technique [0002] In the existing water treatment technology, the traditional fillers are mainly in the shape of clay, rare earth processed ceramsite, sand, and polymer injection molded rings and balls, which not only have low mechanical properties and small surface area, but also And there are still some problems in use. [0003] Pumice, also known as basalt, is a porous rock with certain chemical activity formed when underground magma is sprayed into the air and cooled during volcanic eruptions. At present, the use of pumice is mainly used as lightweight aggregate, thermal insulation material filler, concrete natural lightweight aggregate in building materials, cement active mixed material, preparation of clinker-free cement, filter agent in the chemical industry, drying Agents, catalysts, molecular sieve storage enzyme carriers in petrochemical industr...
