Abstract

The invention relates to a bamboo carbon composite adsorbent which comprises 20-90 parts of bamboo carbon powder, 1-50 parts of anion mineral powder, 2-25 parts of diatomite powder and 5-30 parts of binding agent. The invention has the advantages that: (1) the impurity adsorbing capability of the carbon powder, the anion release capability of the anion mineral powder and the loose expansion capability of diatomite are reasonably combined together, therefore, the bamboo carbon composite adsorbent has more favorable impurity adsorbing capability, higher anion and far infrared release capability and better purification adsorbing function; (2) because of the loose expansion function of the diatomite, the adsorbent has smaller density and light part weight, is used for a hollow glass filling type drying adsorbent instead of a molecular sieve and can be better suitable for the requirement of construction and greatly reduce the cost; and (3) after carrying out coating modification and high-temperature calcination processing, the adsorbent has high strength and hardness and favorable chemical stability, is not dissolved in water and can be used as a water purified adsorbent and an air purified adsorbent.

Description

technical field [0001] The invention relates to a new purification and environmental protection material, in particular to a granulated bamboo charcoal composite adsorbent and a preparation method thereof. Background technique [0002] my country has a large number of rich bamboo plant resources, and its planting area and output rank first in the world. Bamboo resources have the characteristics of strong regeneration ability, short growth cycle, and fast growth (one-year branch, two-year maturity, three-year felling and utilization) and other characteristics. And once planted, it can be continuously grown and utilized, with low planting labor and high utilization rate. Therefore, the bamboo resources can be applied in the fields of chemical industry, medicine, agricultural soil improvement and the like. In particular, it is good for farmers to increase their income, and it is of great significance for the construction of a new rural circular economy. At the same time, bamb...
