Problems solved by technology

Most of the water pollutants in the cellar are suspended solids, high turbidity, high and severe microbial pollution, and some oil and pesticide residues, which are very different from the secondary purification of urban tap water
Therefore, the formula and sintering process of this traditional ceramic filter element slurry must be improved, otherwise the water quality of the cellar water purification using this filter element cannot be guaranteed

Embodiment Construction

[0016] In order to better understand the present invention, the invention will be described in detail below in conjunction with specific examples.

[0017] As mentioned above, in order to overcome the problem that the existing ceramic filter element has an unsatisfactory purification effect on the water quality of the water cellar, the present invention provides a ceramic filter element developed for areas where rainwater is the only water source in northwest villages and towns and the production process of the ceramic filter element.

[0018] In response to the above situation, a certain proportion of attapulgite and bauxite were added on the basis of the original traditional diatomite firing, which enhanced the filter element's ability to adsorb organic phosphorus and carbamate pesticide residues in the water body and structural stress. At the same time, the sintering temperature of the firing process was optimized and controlled, and the research goal was achieved.

Abstract

The invention relates to a ceramic filter element. The ceramic filter element is sintered by adopting kieselguhr, added with attapulgite and bauxite, as a raw material. The invention also relates to a production process of the ceramic filter element. The attapulgite and the bauxite are added on the basis of the kieselguhr serving as a main raw material in the ceramic filter element; the sintered ceramic filter element filters water through mineralization micropores, and can effectively remove particles, suspension and pathogenic bacteria such as escherichia coli, staphylococcus aureus and thelike in the water; and the ceramic filter element simultaneously has an adsorption effect, can strongly adsorb pesticide residues of organic phosphorus and carbamate in the water, and totally meets the requirement on purification of collected rain serving as drinking water in the northwest rural areas. The ceramic filter element is designed aiming at the improved ceramic slurry in the production process, and the ceramic filter element can reach very high filter precision.

Description

【Technical field】 [0001] The invention relates to a ceramic filter element, in particular to a ceramic filter element and a production process of the ceramic. 【Background technique】 [0002] There are many types of ceramic filter elements fired with diatomite as the main raw material, and are widely used in the purification of drinking water. At present, this kind of ceramic filter element commonly used in the market is aimed at the secondary purification of urban tap water. The filtering target is the secondary pollution of the water supply system and the residual pollutants that have not been completely purified by the water plant. [0003] However, due to the harsh natural conditions and underdeveloped economy in the vast area of ​​Northwest my country, farmers live in extreme poverty, especially the drinking water safety problem seriously perplexes the life and economic development of the local people. There are almost no other sources of drinking water in these areas, ...
