Abstract

The present invention discloses a bio-active filler for treating waster and controlling and treating sewage and waste water. Said filler is made up by using natural pumice as raw material, and can be made into the granular form with required size, and the granular density of said filler is 500-800 kg / cu.m perfectly, and its porosity is 40-50% perfectly. Said invented filter is specially applicable to trickling filter bed, anaerobic biological filter, biological fluidized bed and other various filters.

Description

technical field [0001] The invention relates to a bioactive filler used for water treatment, sewage and waste water treatment. Background technique [0002] In the existing 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 exist in use. with some questions. [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. It is light in weight and can float on the water surface, so it is called pumice. 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 and desiccant in the chemical industry ...
