Problems solved by technology

At present, the degradation and monitoring of pollutants are mostly treated separately, and the general operation is complicated, requiring pretreatment or special equipment, many processes, long time and high cost
The commonly used treatment methods have many shortcomings, such as the biodegradation method has a long treatment period and limited treatment capacity; the regeneration energy consumption of the adsorption method is large; the reagents of the chemical method are expensive and easily cause secondary pollution, etc.
The monitoring method also has some disadvantages, such as chromatography requires pretreatment, requires specialized personnel and expensive instruments, sensor analysis is prone to contamination, poor repeatability, and cannot be used for on-site online work

Description

technical field [0001] The invention belongs to the technical field of water pollution control, and in particular relates to a pollutant degradation and monitoring system and its construction method and application. Background technique [0002] With the rapid increase in the discharge of wastewater containing pollutants, some pollutants with certain bioaccumulation, ecotoxicity and refractory self-degradation have adverse effects on human health and the growth and reproduction of animals and plants. For example, the heavy metal hexavalent chromium (Cr(VI)) is easily absorbed by the human body and can cause cancer. Cr(VI) compounds exceeding 10 ppm can cause the death of aquatic organisms. Cr(VI) compounds have been classified as a class of human by the International Agency for Research on Cancer. Serious carcinogen. Common phenolic pollutants, long-term exposure can cause skin and neurological diseases, and excessive intake can cause poisoning. Therefore, the monitoring a...
