Problems solved by technology

Improper disposal of expired medicines is one of the important ways for medicines to enter the environment. According to statistics, about 70% of the medicines in the family medicine cabinet will be idle until they expire, and more than 88% of the expired medicines will be discarded with domestic garbage, or poured into toilets, sinks, etc. Entering into the environment in other ways, leading to drug pollution of the environmental medium and its corresponding ecological risks

Embodiment example

[0028] A harmless treatment method for expired drugs, comprising the following steps:

[0029] (1) Collect common expired antibiotic drug pidotimod granules, remove the outer packaging and mix;

[0030] (2) Collect waste oyster shells from coastal oyster breeding areas, pass through mechanical crushing, mechanical grinding, and pass through a 0.2mm sieve to obtain oyster shell powder;

[0031] (3) Fully mix the prepared oyster shell powder and expired medicine in a mass ratio of 1:60;

[0032] (4) Mix the above mixture with steel balls with a diameter of 3 mm in a mass ratio of 1:60 and place them in a ball mill, and run at a speed of 250 r / min for 4 hours to achieve harmless treatment.

[0033] The harmless effect evaluation test is as follows:

[0034] Tested strains: nitrogen-fixing bacteria

[0035] Liquid LB medium: Weigh 10g tryptone (Tryptone), 5g yeast extract (Yeastextract), 5g NaCl, dilute to 1L with deionized water, adjust pH to 7.4 with 1mol / L NaOH, sterilize R...

Abstract

The invention relates to a harmless treatment method for expired medicines. The waste oyster shells are crushed and ground through a 0.2mm sieve, mixed with expired medicines, placed in a stainless steel tank body of a planetary ball mill, and stainless steel beads are added to the tank body. After capping, in accordance with the loading mode of the ball mill at 250r / min for 4 hours, the harmless disposal of expired drugs can be completed. The technology of the invention makes full use of the adsorption and fixation characteristics of waste oyster shell calcium carbonate, realizes the harmless treatment and disposal of expired drugs under the action of mechanical kinetic energy degradation, and has good environmental and social benefits.

Description

technical field [0001] The invention belongs to the technical field of harmless treatment and disposal of waste, and relates to a harmless treatment technology for expired medicines. Background technique [0002] The environmental pollution of human and animal drugs has become one of the thorny issues in the prevention and management of environmental pollution. The proliferation of drug resistance genes and even the emergence of super bacteria have threatened human health and social sustainability. Improper disposal of expired medicines is one of the important ways for medicines to enter the environment. According to statistics, about 70% of medicines in household medicine cabinets will be idle until they expire, and more than 88% of expired medicines will be discarded with household waste, or poured into toilets, sinks, etc. and other ways into the environment, resulting in drug pollution of environmental media and its corresponding ecological risks. Therefore, the develop...
