Technical Field
The invention belongs to the technical field of biomass recycling, and particularly relates to a preparation method and an application method of pine charcoal.
Background
Phenolic compounds are an important chemical raw material. However, due to improper emission, the organic fertilizer is widely distributed in various environmental media such as water environment, soil environment and the like, and the large exposure of the organic fertilizer can harm human health. At present, common methods for removing the phenol pollutants comprise an adsorption method, a membrane filtration method, advanced oxidative degradation and the like. In the adsorption process, the choice of adsorbent is particularly important. The biochar has wide raw materials, simple and convenient preparation method and good adsorption performance, and is widely concerned in various fields. This patent technique adopts the pine raw materials to calcine the preparation pine charcoal to the phenol that exists in the environment to adsorb with this adsorbing material and handle phenol, in order to reach the effect that the decrement was eliminated.
The invention content is as follows:
the invention aims to solve the problem of phenolic compound treatment, provides a high-efficiency and low-cost charcoal adsorbing material, and provides a preparation method and an application method of pine charcoal.
In order to achieve the purpose, the invention adopts the following scheme:
wherein the preparation of the pine charcoal comprises the following steps:
(1) cleaning pine, and grinding into powder;
(2) calcining pine wood powder at high temperature in N2Calcining at 600 ℃ for 2h under the environment protection to obtain the pine charcoal.
The method is specifically applied as follows:
(1) putting the pine wood charcoal into the phenol water solution to be treated, wherein the using amount of the biochar is 2.5g/L, and the phenol concentration is 50mg L-1-200mg L-1Adjusting the rotation speed to 150rpm for adsorption;
(2) and stopping the adsorption reaction for 24 hours, and filtering and separating the biochar residue to obtain the adsorption reduction post-treatment liquid.
The invention has the advantages that: the process for preparing the biochar is simple and convenient, the efficiency of adsorbing phenol by the biochar is high, and the treatment period only needs 24 hours. The biochar can be widely applied to soil and water pollution remediation, and is wide in application range.
