Problems solved by technology

In addition, tea trees are perennial shrubs. In order to increase the service life of tea trees and ensure the quality and output of tea every year, tea trees need to be pruned in summer and autumn every year. The branches have not been effectively used at present, and the directly discarded tea tree branches have caused a direct waste of resources
However, so far, there is no report on the application of tea charcoal in water purification materials

Embodiment 1

[0026] A tea charcoal water purification material is prepared from branches mowed in winter. The preparation method specifically includes collecting clean tea tree branches as raw materials, sintering at a high temperature of 650° C. for 2 hours, carbonizing until smokeless, and crushing.

[0027] In this example, the pore diameter of the obtained tea charcoal water purification material is 500nm-65μm, and the specific surface area is 124m 2 / g.

[0028] The test results of dynamic adsorption show that the removal rate of sediment, heavy metals and dyes is 85.3% when the tea charcoal water purification material is loaded into the filter column with a height-to-diameter ratio of 20 and the flow rate is controlled at 5ml / min.

[0029] Put the dried tea charcoal water purification materials into the concentration of 1.5×10 -4 mol / L rhodamine B solution and methylene blue solution, and with stirring, the stirring speed is 300rpm, and the concentration is tested every 20min during...

Embodiment 2

[0037] A tea charcoal water purification material is prepared from branches pruned in autumn. The preparation method specifically includes collecting clean tea tree branches as raw materials, drying at 85°C until the water content is 2%, and then pressing at 12MPa for 10 minutes, and Sinter at a high temperature of 780°C for 6 hours, carbonize until there is no smoke, pulverize at 450rpm for 3 minutes, and pass through a 160-mesh sieve.

[0038] In this example, the pore diameter of the obtained tea charcoal water purification material is 850nm-15μm, and the specific surface area is 186m 2 / g.

[0039] The test results of dynamic adsorption show that the removal rate of sediment, heavy metals and dyes is 93.3% when the tea-charcoal water purification material is loaded into a filter column with a height-to-diameter ratio of 20 and the flow rate is controlled at 5ml / min.

[0040] Put the dried tea charcoal water purification materials into the concentration of 1.5×10 -4 mol / L...

Abstract

The invention discloses a tea-carbon water purifying material, and a preparation method and application thereof. The tea-carbon water purifying material is a powdery porous carbon structure obtained by high-temperature sintering of clean tea tree branches, the pore diameter ranges from 50 nanometers to 80 microns, and the specific surface area is in a range of 90 m<2> / g-500 m<2>g. The preparationmethod of the material comprises collecting the clean tea tree branches as raw materials, carrying out carbonization at a high temperature and carrying out crushing. The application of the material isadsorption of dye, oil, organic solves and heavy metal ions. The result shows that the tea-carbon water purifying material provided by the invention has easily available raw materials and low cost, has no chemical residues after the high-temperature carbonization, contains no chemical reagent components, is a water purification material with zero addition, zero pollution and high benefit, and notonly can efficiently adsorb dye, oil, organic solvents and heavy metal ions in water, but also can be subjected to redox reactions or complexation reactions with active substances, metals and the like in the water. The raw materials are abundant and easily obtained, the preparation method is simple and controllable, and the application prospect is wide.

Description

technical field [0001] The invention relates to the technical field of application of water purification materials, more specifically, to a tea charcoal water purification material and its preparation method and application. Background technique [0002] With the rapid development of the global economy, the demand for industrial and domestic water has doubled, and the resulting water pollution has also increased. Low-pollution water produced in human production and life with low hazards, such as tail water from municipal and industrial sewage treatment plants, discharge water after treatment of large-scale aquaculture water, effluent after treatment of rural domestic sewage, initial rainwater in villages and towns, and agricultural planting Runoff, etc., due to the large amount of water and its ubiquity, driven by the natural water cycle, all types of water have cross-contamination. The water quality problem is a major problem faced by human beings and the organisms they dep...
