Abstract

The present invention relates to a catalytic oxidation apparatus for water treatment, and a production method thereof, and a water treatment process. A purpose of the present invention is to solve the technical problems of difficult removal of organic pollutants from polluted water sources and low water purification efficiency in the existing water treatment technology. According to the present invention, active carbon and quartz sand are subjected to mixing alkalization activation to form the catalytic oxidation apparatus with characteristics of developed pore structure, large specific surface area, high adsorption capacity and high speed; the water treatment process comprises multi-medium filtration-membrane separation-catalytic oxidation and other links, wherein the polysilicic acid structure and the poly iron structure are formed on the surface during the iron supporting and alkalization activation process of the active carbon and the quartz sand in the catalytic oxidation link so as to provide catalysis effects for a variety of difficultly-degraded organic matters; and the apparatus can be used for the rapid and safe treatment of non-standard surface water, groundwater and other emergency water source water under emergency conditions so as to make the obtained water achieve the drinking water standard, and can further be used in the fields of deep treatment, reuse and the like of difficultly-degraded organic polluted wastewater.

Description

technical field [0001] The invention belongs to the field of water treatment, and in particular relates to a catalytic oxidation device for water treatment, a manufacturing method thereof and a water treatment process. Background technique [0002] Water pollution and sudden water pollution accidents occur from time to time. Natural disasters such as earthquakes and floods, and water supply difficulties caused by human factors such as wars and accidents have a great impact on the lives and production of residents and cause serious harm. The study of drinking water supply technology under the conditions of sudden pollution and disasters has attracted widespread attention from all over the world. Developed countries such as the United States, Japan, Israel, and Germany attach great importance to the technical research on water security for sudden pollution accidents. In recent years, my country has carried out a lot of research on emergency water treatment system technology....
