Abstract

The invention relates to a wastewater and waste gas pollutant treatment ball loaded with composite modified nanometer TiO2. The wastewater and waste gas pollutant treatment ball comprises an active microporous ball, the composite modified nanometer TiO2 and a plant-extracted photosensitizer or strong oxidant, wherein the composite modified nanometer TiO2 and the plant-extracted photosensitizer orstrong oxidant are sequentially loaded on the active microporous ball. According to the invention, the composite modified nanometer TiO2 and the plant-extracted photosensitizer or strong oxidant are sequentially loaded on the active microporous ball, so an obtained treatment ball has an active group with high energy; the diameter and the stacking layer thickness of the treatment ball can be determined according to the pollutant concentration and variety; during waste gas treatment, waste gas can be placed in a waste gas exhaust channel; and by utilization of the maze principle, pollutants in the waste gas react with active groups with high energy and are finally converted into substances like CO2 and H2O.

Description

technical field [0001] The invention relates to a loaded composite modified nano-TiO 2 The utility model relates to a waste water and gas pollutant treatment ball, belonging to the field of polluted waste water or flue gas purification treatment facilities. Background technique [0002] my country is becoming the largest country in the manufacturing industry, which has driven the development of the national economy, but at the same time it has also brought serious waste gas pollution problems. Different industries emit different types of waste gas. At present, due to the increasingly complex composition of industrial waste gas, Although the VOCs waste gas treatment methods commonly used in my country can reduce air pollution to a certain extent, they still cannot be effectively treated and completely eradicated. At the same time, due to the rapid development of the industrial industry, the amount of waste gas emissions in the atmosphere has increased significantly. It is di...
