Embodiment Construction

[0015] The present invention mainly modifies two kinds of activated carbons by changing the type, concentration and treatment temperature of the acid, and compares the adsorption of the simulated dye wastewater Rhodamine B solution by the activated carbons that have not been treated and treated under different conditions, and obtains the rhodamine B The solution has a modified activated carbon powder with a strong adsorption effect.

[0016] 1. Treatment of activated carbon powder

[0017] Weigh 3 parts of activated carbon powder (5g), add 30mL hydrochloric acid (HCl) solution of different concentrations respectively, stir at room temperature for 4 hours, boil and wash the activated carbon treated with hydrochloric acid with distilled water until neutral, and then dry to obtain 2-4 No. sample for standby; use nitric acid (HNO 3 ) instead of hydrochloric acid, and the same method was used to process activated carbon to obtain No. 5-7 samples for later use; 4 parts of activated ca

Abstract

The invention discloses an application of modified activated carbon in sewage treatment. The application is characterized in that the modified activated carbon is selected from activated carbon treated with hydrochloric acids and nitric acids of different concentrations, or treated at a high temperature. After the activated carbon used in the invention is treated with hydrochloric acids and nitric acids of different concentrations at different temperatures for a certain period of time, the adsorption capability of activated carbon powder is increased remarkably, and a good treatment effect on sewage containing rhodamine B serving as a dye is achieved particularly.
