Abstract

The invention discloses an oxide ceramic filter material and a preparation method. The oxide ceramic filter material comprises the following compositions by weight portion: 10 to 60 portions of CaO, 1 to 60 portions of MgO, 10 to 40 portions of SiO2, 5 to 20 portions of Al2O3, 0 to 15 portions of TiO2, 0 to 25 portions of ZnO and 0.1 to 1 portion of Fe2O3. The basic principle of the filter material is to complete the function of high-efficiency filtration by the function that adsorbed antibacterial materials subjected to physical filtration release active oxygen when reacting with water. The oxide ceramic filter material mainly aims to solve the problem of water quality deterioration caused by various pollutants in water bodies, and simultaneously has strong sterilization and algae removal properties.

Description

technical field [0001] The present invention relates to a filter material for water treatment and its preparation method, in particular to a kind of water treatment which is composed of various oxide ceramic powders and specially treated, and is suitable for water quality of various surface waters and reused reclaimed water. Filter material and its preparation method. The water treatment filter material has the excellent performance of decontamination and deodorization, COD reduction, and sterilization and algae killing performance. Background technique [0002] Filter media play an important role in the water treatment industry. There are many new filter materials reported in the literature, and the general development trend is that more attention is paid to the research and application of oxide ceramic filter materials. However, most of the existing oxide ceramic filter materials mainly solve the effect of physical filtration. The functions of other filter materials foc...
