Embodiment 1

[0028] A method for the harmless co-processing of waste drug residues in pharmaceutical factories in cement kilns, the flow chart is shown in figure 1 shown, including the following steps:

[0029] Fill penicillin mycelia waste residue with a water content of 95wt% (that is, a solid content of 5wt%) into a closed waste drug residue storage tank (1000t in storage capacity), a total of six sealed waste drug residue storage tanks are equipped with explosion-proof and gas collection devices;

[0030] Put the lumpy quicklime into the storage shed (12000t in reserve); put the lumpy quicklime in the storage shed into the crusher for crushing, and send it to the steel plate storage shed through the conveying equipment (6000t in storage);

[0031] ③ Combine the crushed quicklime with the step The penicillin mycelia waste residue in the medium is added to the digestion device for digestion in a ratio of 1:2.8 by weight to obtain a digested product. The digestion time is 5min, and...

Embodiment 2

Abstract

The invention discloses a cement kiln harmless pharmaceutical factory waste residue co-processing method, and relates to the technical field of waste water and waste residue processing. The method comprises the following steps: waste residues are injected into airtight waste residue storage tanks; bulk calcined lime in a storage shed is broken and stored; the broken calcined lime and the waste residue are added into a digestion device for digestion to obtain a digestion object, wherein the moisture content of the digestion object is smaller than or equal to 20%; the digestion object is placed into an airtight digestion object storage tank for storage and standby use; the waste residue storage tanks and the digestion object storage tank are provided with gas collection devices; the digestion object and raw materials for cement production are mixed for compounding, wherein the mass fraction of the digestion object is 20-80%, and the mass fraction of the raw materials for cement production is 80-20%; and the materials and gases collected by the storage tanks are fired into cement clinkers which conform to national standards under the temperature of 1350-1500 DEG C by using a cement production line, and exhaust gases after processing the waste residues by a cement kiln conform to the national standards. The cement kiln harmless pharmaceutical factory waste residue co-processing method is simple, low in cost and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of waste water and waste residue treatment. Background technique [0002] Waste drug residue mainly refers to antibiotic mycelium waste residue, which mainly contains crude protein, sugar and other nutrients and a small amount of residual antibiotics. It is easy to ferment and deteriorate and emit foul smell. It has a high moisture content (above 90%) and is difficult to dehydrate. In 2008, the country listed antibiotic mycelium residues in the list of hazardous wastes. With the continuous expansion of the scale of my country's pharmaceutical companies, only about 42 million tons of antibiotic mycelium waste residues (water content 90%) are produced in the country every year. How to safely and effectively dispose of large-scale waste medicine residues has become a major problem facing my country's pharmaceutical industry today. [0003] The disposal of waste medicine residues generally includes the followin...
