Embodiment 1

[0028] ① Take 1.3kg of coking coal, 0.7kg of asphalt, 1.5kg of long-flame coal, and 1.2kg of blue charcoal powder, mix them uniformly mechanically, and then crush them with a sample making machine to make a 150-mesh uniform mixture A 1 .

[0029] ②Take 5kg of penicillin hyphae and pre-dry them at 120°C, and crush them to a powder with a particle size of 150 meshes, then use phosphoric acid at a ratio of 1:1.5 for pickling and activation, and the concentration of phosphoric acid used is 70%. The activated mycelium was heated in an oil bath at 150°C, and stirred continuously until the mycelium was matured to plasticity, and the curing time was 1 hour to obtain the mycelium pretreatment component B 1 .

[0030] ③ Dissolve 0.05kg of tapioca starch, 0.05kg of polyethylene glycol, 0.05kg of polyvinyl alcohol and 0.05kg of baking soda in 0.05kg of water and 0.05kg of ethanol to obtain the bonding component C 1 .

Abstract

The invention discloses a VOCs adsorbent prepared from hypha solid waste resources and coal, and a preparation method thereof, and belongs to the field of environmental protection, solid waste utilization and catalysis. The problems of poor adsorption performance and short service life of an existing adsorbent are solved. The preparation method comprises the following steps: mechanically mixing coking coal, asphalt, long flame coal and semi-coke powder in proportion, and crushing by a sampling machine in a unified manner; pickling and activating penicillin hyphae, curing, mechanically mixing with pulverized coal, baking soda and cured starch, adding water, and kneading; and granulating the obtained mixture, carbonizing, and washing with water to obtain the high-performance VOCs adsorbent.The high-performance VOCs catalyst is prepared by taking the waste hyphae as the main raw material, so that the problems of low activity and poor adsorption performance of the catalyst are solved, thecomprehensive utilization of hypha solid waste resources is realized, and the damage of solid wastes to the environment is reduced.

Description

technical field [0001] The invention belongs to the technical fields of environmental protection, solid waste utilization and catalysis, and specifically relates to a high-performance VOCs adsorbent prepared by using penicillin mycelia solid waste resources and coal resources and a preparation method thereof. Background technique [0002] Penicillin waste mycelium is a residue produced during the preparation of penicillin in the biopharmaceutical industry, and it is a dangerous solid waste. According to the survey, my country's penicillin production accounts for one-third of the world's total, and the waste mycelia produced by major pharmaceutical factories every year is tens of thousands to hundreds of thousands of tons, which is huge and causes serious pollution to the environment. At present, domestic treatment methods include: incineration, burial or feed treatment, but incineration and burial will cause serious environmental pollution, and the treatment as animal feed h...
