Abstract

The invention discloses a method for synchronously removing antibiotic and heavy metal combined pollution in water, and belongs to the technical field of sewage treatment. The method comprises the following steps: adding a glucose-based mesoporous carbon material into a water body containing antibiotics and heavy metals, adjusting the pH value of the solution to 3-7, and carrying out an oscillation reaction at 22-28 DEG C for 180 min, wherein the addition amount of the glucose-based mesoporous carbon material is 0.5 g / L. The method is simple and convenient to operate and mild in condition, andcan realize synchronous and efficient removal of antibiotic and heavy metal combined pollution in the water body.

Description

technical field [0001] The invention relates to a method for synchronously removing combined pollution of antibiotics and heavy metals in water, belonging to the technical field of sewage treatment. Background technique [0002] At present, with the rapid development of livestock and poultry breeding, aquaculture and other industries, antibiotics or heavy metals are frequently detected in the water environment, posing an increasingly serious potential threat to the aquatic ecological environment and human health. The coexistence of antibiotics and heavy metals to form complex pollution has become one of the typical pollution types in the water environment and water treatment process. Due to the complexity of the coexistence characteristics of pollutants, the development of removal technologies for antibiotics and heavy metal complex pollutants has become a research hotspot and difficulty in the field of environment. In the comprehensive analysis of the adsorption and remova...
