Composite ceramic water purification agent

Abstract

The invention discloses a composite ceramic water purification agent, which is a porcelain granule or a pottery shard or a clay pipe with a porous mesh structure obtained by calcining a blank. The blank comprises the compositions according to the following weight percentage: 30 to 90 percent of carbon, 4 to 30 percent of silicon dioxide, 1 to 10 percent of zinc oxide, 0 to 15 percent of sodium sulfate and / or potassium sulfate, 1.5 to 6 percent of calcium oxide, 1.5 to 8 percent of aluminum oxide, 1 to 6 percent of magnesia, and 0.5 to 3 percent of ferric oxide. The porous mesh structure has the characteristics of decoloring and deodoring; a material with antibacterial and algae-inhibiting characteristics is a built-in electric field on a microscopic structure which mainly comprises zinc oxide and so on; and the built-in electric microfield effect is utilized to change surface characteristics of microorganisms, which can inhibit the propagation and growth of the microorganisms to achieve the aims of antibacterium and algae inhibition.

Description

1. Technical field [0001] The invention relates to a water purifying agent, in particular to a composite ceramic water purifying agent. 2. Background technology [0002] In the industrial or civil field, the methods for removing microorganisms in liquid or gaseous media generally fall into the following categories: [0003] 1. Filtration method: let the liquid or gas medium flow through a porous filter body with a smaller pore size, let the liquid or gas pass through, and the bacteria are trapped. This method requires that the pore size of the product must be extremely narrow step by step, and the pore size may not be greater than 0.2 microns. Based on the characteristics of this method, its filtration flux or daily filtration efficiency is relatively low. [0004] 2. Ultraviolet disinfection method: This method uses the killing effect of ultraviolet rays on microorganisms to remove microorganisms in liquid or gaseous media. UV lamps are usually placed in reservoirs and ha...

[0006] 4. Chemical agent method: silver-based antibacterial agents obtain antibacterial properties through the action of dissolved silver ions on microorganisms. Although they have good antibacterial properties, they also make water bodies The silver ions in the water exceed the relevant water quality standards. In addition, its timeliness and anti-aging properties have always been to be further improved; studies have shown that chlorine-containing preparations (including liquid chlorine and chlorine dioxide) will lead to the generation of such as chloroform, Carcinogens such as hypochlorite
