Abstract

The invention provides a preparation method and an application of a biochar-Ni / Fe layered double hydroxide composite material, relates to the fields of biomass processing and biochar modification, inparticular to a preparation method and an application of modified biochar and aims to solve the problem of poor adsorption performance in the process of removing pesticides and other organic pollutants in / from water bodies in the prior art. Biochar and a layered double hydroxide material are composited, thereby fully playing respective functions and generating superposition effects. The biochar-Ni / Fe layered double hydroxide composite material is used for adsorption of organic pollutant atrazine, except heavy metals.

Description

technical field The invention relates to the fields of biomass processing and biochar modification, in particular to a preparation method and application of modified biochar. Background technique Black and odorous water in urban areas not only brings poor sensory experience to the masses, but also a prominent environmental problem that directly affects the lives of the masses. According to the clear requirements for the treatment of black and odorous water bodies in the "Water Pollution Prevention and Control Action Plan", by 2020, the black and odorous water bodies in the built-up areas of cities at the prefecture level and above in my country will be controlled within 10%, and the black and odorous water bodies in urban built-up areas will be eliminated in general. However, the original pollution in the current agricultural life has not been completely eliminated, and new pollution has begun to spread, so the treatment of organic pollutants in water bodies is imminent.
