Abstract

The invention discloses a ceramic filter element of diatomite composite activated carbon as well as a production method thereof. The key point of the technical scheme is as follows: the filter elementconsists of the following raw material components in parts by mass: 80 to 90 parts of diatomite, 8 to 15 parts of activated carbon, 3 to 5 parts of polyvinyl alcohol, 2 to 3 parts of calcite, 2 to 3parts of a hargil powder, 2 to 3 parts of dolomite, 2 to 3 parts of a pore-forming agent and 0.5 to 1.0 part of a burning accelerant; and after semi-dry pressing forming, the effects of removing colloidal substances such as silt and rust from water, improving the turbidity of the water, removing the residual chlorine of the water, enabling the pH value of the water to be slightly weak alkaline andadapting to the internal environment of a human body are achieved.

Description

technical field [0001] The invention relates to the field of filter elements, in particular to a ceramic filter element of diatomite composite activated carbon and a production method thereof. Background technique [0002] Water is the source of life and is closely related to people's health. With the development of economy, people's requirements for water quality are getting higher and higher. However, due to the rapid development of industry and the vigorous development of mining, the water quality of most surface water sources in the country is deteriorating. [0003] Installing a filter under the household faucet can effectively intercept bacteria and absorb organic matter and heavy metal ions remaining in the water, improve the quality and taste of drinking water, and retain trace elements necessary for the human body. At present, there are two types of faucet water purification filter elements on the market: hollow fiber membrane filter elements and ceramic membrane f...
