Problems solved by technology

The stem bark of ramie has long fibers, high elasticity, high heat resistance, and good insulation. It can be used as an excellent textile raw material. Ramie root is a traditional Chinese medicine that can be used as medicine. Too many ramie stalks are discarded, and the adsorption effect of raw biochar prepared from ramie stalks is not ideal when used as an adsorbent for water pollutants

Embodiment 1

[0031] A ramie biochar for purifying waste water is prepared from the following quality raw materials: 10 g of egg shell powder and 10 g of ramie rod powder.

[0032] A preparation method of ramie biochar for purifying waste water, comprising the following steps:

[0033] S1, get ramie pole, peel, dry, pulverize and cross 60 mesh sieves to obtain ramie pole powder; Get egg shell washing, drying, pulverizing, cross 60 mesh sieves, obtain egg shell powder;

[0034] S2. Weigh 10g egg shell powder and 10g ramie rod powder and place them in a ball mill, add ZrO 2 Grinding balls for 60min;

[0035] The ZrO 2 The particle sizes of the grinding balls are 0.2cm, 0.6cm, and 1.0cm, respectively, and ZrO with a particle size of 0.2cm, 0.6cm, and 1.0cm 2 The mass ratio of grinding balls is 1:4:6, and the total mass is 120g;

[0036] S3. After ball milling, the ramie biochar is obtained by carbonization at a constant temperature of 800 °C for 2 hours.

Abstract

The invention belongs to the technical field of biochar, and particularly relates to ramie biochar as well as a preparation method and application thereof.The ramie biochar for purifying wastewater is prepared from the following raw materials in parts by mass: 1-2 parts of egg shell powder and 1 part of ramie stem powder; the preparation method of the ramie biochar for purifying wastewater comprises the following steps: weighing 1-2 parts of egg shell powder and 1 part of ramie stem powder, mixing to obtain mixed powder, and uniformly crushing; s3, after crushing, keeping the temperature at 650-800 DEG C for 2-3 hours, and carbonizing to obtain ramie biochar; the prepared ramie biochar is used for removing phosphate in water, the adsorption performance can reach 100%, and the ramie biochar adsorbing phosphate can be directly used as a fertilizer with high added value to be added into soil.

Description

technical field [0001] The invention relates to the technical field of biochar, in particular to a ramie biochar and a preparation method and application thereof. Background technique [0002] Phosphorus content in water is one of the important indicators affecting water quality. When the phosphate content in water exceeds 10 μg / L, the water body is prone to eutrophication. Ramie stem bark has long fiber, high elasticity, high heat resistance and insulation, and can be used as an excellent textile raw material. Ramie root is a traditional Chinese medicine, which can be used as medicine. Too many ramie rods are abandoned, and the adsorption effect of the original biochar prepared from ramie bone is not ideal when it is used as an adsorbent for water pollutants. Therefore, it is necessary to propose a high-performance ramie biochar to treat and repair eutrophic river and lake water bodies, restore the use function of water bodies, and effectively alleviate the problem of lack...
