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

A VOCs adsorbent prepared by using mycelia solid waste resources and coal and its preparation method, which belong to the field of environmental protection, solid waste utilization and catalysis, can solve the problems of poor adsorption performance and short life of existing adsorbents. , long-flame coal, and semi-coal powder are mechanically mixed in proportion, and uniformly crushed with a sample making machine. The penicillin mycelium is acid-washed and activated, and after being matured, it is mechanically mixed with the above-mentioned coal powder, baking soda and cured starch, and mixed with water. After the mixture is granulated, it is carbonized and washed with water to obtain a high-performance VOCs adsorbent. The invention uses waste mycelium as the main raw material to prepare high-performance VOCs catalyst, which not only solves the problems of low catalyst activity and poor adsorption performance, but also realizes the comprehensive utilization of mycelium solid waste resources and reduces the impact of solid waste on the environment. destroy.

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...
