Abstract

The invention provides a reused nano-coating structure for sewage treatment and an application method thereof. The nano-coating structure is obtained through preparing sulfur-doped nano titanium dioxide, preparing a modified coating material by using the obtained sulfur-doped nano titanium dioxide, preparing an aluminum-alloy micro-arc-oxidated film, and coating the micro-arc-oxidated film with the obtained modified coating material. The reused nano-coating structure for sewage treatment, provided by the invention, has the advantages of high catalytic degradation efficiency, easiness in recovery and reuse and can be recycled repeatedly by a special application method.

Description

technical field [0001] The invention relates to the technical field of sewage treatment materials, in particular to a nano-coating structure and an application method for recycling and treating sewage. Background technique [0002] Excessive consumption of water resources and environmental pollution lead to the shortage of water resources has become a major issue of global concern. Especially under the premise of uneven distribution of water resources in my country and relatively poor water resources, due to supervision and other issues, the pollution of water resources is very serious. Water pollution destroys the ecological environment, endangers human health, affects the vitality of the people, and greatly restricts the development of the national economy. Therefore, sewage treatment and essence are a major problem that needs to be solved urgently. [0003] The main factors affecting water quality are organic pollutants and microorganisms in water. Organic pollutants deg...
