Problems solved by technology

[0004] At present, there is no unified standard in the world to supervise and manage the performance of drinking water filters, resulting in uneven quality of drinking water filters on the market. For users, it is very difficult to judge the purification effect of drinking water filters on the market. , some studies have shown that the failure rate of household drinking water filters is relatively high

Abstract

The invention relates to a method for testing the purification effect of a drinking water filter element. The method comprises the following steps: testing the basic performance of a filter element raw material, testing the water purification effect of a formed filter element, and testing and analyzing the microstructure characterization of the formed filter element. Wherein the test of the basic performance of the raw material of the filter element is to test a carbon material in the filter element, and test indexes comprise a moisture content test, an ash content test, a volatile component test and a fixed carbon test; the test of the water purification effect of the formed filter element comprises an adsorption test of the filter element on formaldehyde in water, an adsorption test of the filter element on a permanganate index standard substance (CODMn), an adsorption capacity test and a test of the filter element on the removal rate of trace elements in the water. According to the method, the purification effect of the filter element is tested, the product quality can be better determined in the product development process, the problem that the filtering effect of the filter element does not reach the standard is avoided, theoretical support is provided for application of preparation of the purification filter element from the carbon material, and the method has important theoretical practical significance.

Description

technical field [0001] The invention relates to the technical field of filter elements, in particular to a method for testing the purification effect of drinking water filter elements. Background technique [0002] Drinking water is an indispensable element of human metabolism. Most human diseases are closely related to drinking water. With the rapid development of industry, the acceleration of urbanization and various human activities, rural areas and Urban drinking water has been seriously polluted. The pollutants mainly include organic pollutants, inorganic pollutants, biological pollutants and radioactive pollutants. The main hazards are the "three causes" (carcinogenic, teratogenic and mutagenic) produced by organic pollutants. Problems, drinking water pollution has become a hot spot of global concern, carbon materials have strong adsorption, is one of the main materials for drinking water purification. [0003] As a porous material with strong adsorption properties, c...
