Example Embodiment

[0027] Example 1

[0028] ① Take 1.3 kg of coking coal, 0.7 kg of pitch, 1.5 kg of long flame coal, and 1.2 kg of blue charcoal powder, and mix them evenly, and then crush them with a sample preparation machine to make a homogeneous mixture A of 150 mesh 1 .

[0029] ② Take 5kg of penicillin hyphae at 120℃ for pre-drying treatment, and crush it to a powder with a particle size of 150 mesh, and then use phosphoric acid with a ratio of 1:1.5 for pickling activation. The concentration of phosphoric acid used is 70%. The activated hyphae are heated in an oil bath at 150°C, under constant stirring, until the hyphae are matured to be plastic, and the maturation time is 1h to obtain the hyphae pretreatment component B 1 .

[0030] ③ Take 0.05 kg of tapioca starch, 0.05 kg of polyethylene glycol, 0.05 kg of polyvinyl alcohol and 0.05 kg of baking soda and dissolve them in 0.05 kg of water and 0.05 kg of ethanol to obtain the binding 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...
