Composite ceramic water purifying agent

Abstract

The invention discloses a composite ceramic water purifying agent. The composite ceramic water purifying agent is a porous net-shaped ceramsite or ceramic sheet or ceramic tube obtained by calcining ablank, and the blank comprises the following components in percentage by weight: 30-90% of carbon, 4-30% of silicon dioxide, 1-10% of zinc oxide, 0-15% of sodium sulfate and / or potassium sulfate, 1.5-6% of calcium oxide, 1.5-8% of aluminum oxide, 1-6% of magnesium oxide and 0.5-3% of ferric oxide. The porous net structure has decolorizing and deodorizing characteristics. A material with antibacterial and algae-inhibiting characteristics is mainly composed of zinc oxide and the like, and a built-in electric field is formed in a microstructure. The surface characteristic of microorganisms is changed by utilizing a built-in micro-electric field effect, so that propagation and growth of the microorganisms can be effectively inhibited, and a purpose of resisting bacteria and inhibiting algae is achieved.

Description

technical field [0001] The invention relates to a water purifying agent, in particular to a composite ceramic water purifying agent. Background technique [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 FI 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 have limit...

[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, while obtaining better 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 been to be further improved; studies have shown that chlorine-containing preparations (including liquid chlorine and chlorine dioxide) will lead to the formation of such as chloroform, Carcinogens such as hypochlorite
