Embodiment 1

[0023] Take out the bacterial aerobic granular sludge in the reactor and put it into a beaker, wash it with tap water for 2-3 times, then wash it with deionized water for 2-3 times and dry it for later use. Measure 250ml of deionized water and pour it into a 500m conical flask, weigh 6.75g of ferric chloride solid in the bottle, cover it and shake it in a shaker until the solid is completely dissolved, then weigh 20-25g of granular sludge ( Wet weight) in a bottle, shake at a constant temperature for 18-24 hours at a temperature of 30-35°C and 150-175rpm. After the granular sludge and the modifier have fully reacted, take out the bottle and let it stand for 5 seconds, then pour it out. Supernatant, add deionized water to wash, wash in this way 4-6 times, until the supernatant is clear, colorless and transparent; add deionized water again and let stand overnight (12-24 hours), then pour out the supernatant, Wash again 2-4 times until the pH in the solution is stable at 4-4.5, a...

Abstract

The invention belongs to the technical field of preparation of a biological material, and particularly relates to a modification method of bacterial biological particle adsorption materials aiming at efficient removal of antimonite. Bacterial aerobic granular sludge is taken as a raw material, and simple chemical modification treatment, including the procedures of washing, mixing vibrating, washing, standing, water solution storage and the like is carried out, so that the removal efficiency of the modified biological particle adsorption materials on Sb(V) is greatly improved. The method disclosed by the invention has the characteristics of being simple in process, convenient to operate, low in cost, short in operation cycle and the like, and above all, no secondary pollution to the environment is generated, so that the modification method is a real resource-saving and environment-friendly biological material modification method. The adsorption material modified by the method disclosed by the invention has the advantages of good settling property, stable biophase, high removal efficiency and the like relatively to the other biological materials.

Description

technical field [0001] The invention belongs to the technical field of biological material preparation, and in particular relates to a modification method of a biological particle adsorption material aimed at efficiently removing antimonate. technical background [0002] Due to the gradual understanding of the environmental behavior and toxicological characteristics of the metalloid element antimony, antimony pollution is attracting more and more attention. Antimony is not an essential element for the human body. When antimony and its compounds combine with sulfhydryl groups in the human body, they will interfere with the activity of enzymes in the body and destroy the ion balance in the cells, causing the cells to be hypoxic and causing metabolic disorders in the human body. Both the U.S. Environmental Protection Agency and the European Union have listed antimony as a priority pollutant and clearly stipulated that the content of antimony in drinking water should not exceed ...
