Abstract

The invention relates to a tourmaline ceramic supporting TiO 2 —The preparation process of NCP solid-supported photocatalyst, which belongs to the field of water purification agent processing; the tourmaline ceramic supports TiO 2 —The preparation process of NCP immobilized photocatalyst includes the following specific steps: 1) Preparation of tourmaline ceramics; 2) TiO 2 —Preparation of NCP composite photocatalyst; 3) Tourmaline ceramic supported TiO 2 —Preparation of NCP-immobilized photocatalyst. The present invention utilizes multi-element doped TiO prepared by tourmaline ceramics 2 / TCB composite photocatalyst, multi-element co-doped TiO 2 / TCB composite photocatalyst can deeply process HOCs in water under natural conditions, and generates "zero" waste. It is an environmentally friendly green product.

Description

technical field [0001] The invention belongs to the field of water purifier processing, in particular, relates to a tourmaline ceramic loaded TiO 2 —The preparation process of NCP immobilized photocatalyst. Background technique [0002] With the development of industry and agriculture, a large and increasing amount of HOCs must eventually enter the natural water cycle system and inevitably appear in drinking water; especially the abuse of human and veterinary drugs, the flood of electronic and plastic waste, make emerging Organic harmful substances are constantly emerging in drinking water; they are highly toxic and highly bioaccumulative, and even in a very small amount, they will pose a great risk to human health. In my country, the level of individual persistent organic pollutants in the water system is at the high end in the world. [0003] It is necessary to completely remove HOCs in drinking water to protect human health. At present, the removal of HOCs is not consid...
