Problems solved by technology

[0004] For this reason, the present invention provides a drug harmless treatment method with good effect and easy operation to solve the problem of relatively large environmental pollution in drug treatment in the prior art. The present invention can process methamphetamine, heroin, marijuana and other drugs Organic matter or its intermediates and solutions in the manufacturing process; the use of supercritical water oxidation method to degrade toxic and harmful organic matter solves the problem of secondary pollution and incomplete degradation of traditional drug treatment

Embodiment 1

[0036] Such as figure 1 As shown, a drug harmless treatment method in this embodiment, step S100, fully dissolve (miscible) the drug sample (solid or liquid) in an aqueous solution to form a drug solution; step S200, add an oxidizing agent to the drug solution , putting the drug solution after adding the oxidant into the reactor for treatment by supercritical water oxidation; step S300, measuring the organic content in the drug solution before and after the reaction, and obtaining the degradation rate of the organic component.

[0037] The above method is to carry out high temperature and high pressure reaction degradation (not required to be soluble in water) in the reactor after the drug is prepared with a certain concentration in water, and the remaining organic matter content in the treated reaction product is detected to determine the achieved after treatment. The degradation rate; the supercritical water that present embodiment adopts refers to the reaction condition tha...

Embodiment 2

[0040] Such as figure 1As shown, a drug harmless treatment method in this embodiment includes all the technical features in embodiment 1. In addition, before the toxic drug powder is fully dissolved in water, it also includes weighing the drug. and stirring treatment, step S100 also includes: weighing the drug sample, using an analytical balance when weighing, the accuracy of the analytical balance is higher than 0.0001g, and the quality of the drug sample is 0.1%-20% of the quality of the drug solution; step S100 It also includes: using a magnetic stirrer to stir the drug solution, and the stirring time is 5 minutes to 60 minutes; drug samples are organic drugs or intermediates and solutions in the manufacturing process of organic drugs, such as methamphetamine, heroin and marijuana (but not only limited to this), can also be used for other toxic organic compounds, organic waste water, sludge, solid waste, etc.; the oxidizing agent is hydrogen peroxide, and the quality of the...

Embodiment 3

[0052] Such as image 3 Shown, a kind of drug harmless treatment method in the present embodiment, sample is methamphetamine (methamphetamine) aqueous solution, methamphetamine and water are made into the concentration of 1.5mg / ml, stand-by after stirring. Aqueous methamphetamine and 30% H 2 o 2 Put it into the reaction kettle, close the reaction heating device, check the air-tightness between each valve and the nut, after the inspection is completed, insert the thermocouple and start heating. The reaction device should be 1 meter away from the wall horizontally, and there should be no shelter around the device. The horizontal distance to the air supply outlet of the building should not be less than 1 meter, the device is installed horizontally, the reaction temperature is 500°C, the pressure is 21MPa, 23MPa, 25MPa, 27MPa, and other conditions remain unchanged. It can be seen from the content and changes of organic components that when the pressure reaches 23MPa, 25MPa, and ...

Abstract

The invention discloses a harmless treatment method for drugs. The harmless treatment method comprises the following steps: step S100, fully dissolving a drug sample in an aqueous solution to form a drug solution; step S200, adding an oxidizing agent into the drug solution, and putting the drug solution added with the oxidizing agent into a reaction kettle for treatment by a supercritical water oxidation method; and step S300, measuring the content of organic matters in the drug solution before and after the reaction to obtain the degradation rate of organic matter components. The method has the advantages of high degradation efficiency (up to 99.99% or above), no secondary pollution and the like, especially has more obvious advantages in treatment of drugs and high-toxicity, degradation-resistant and high-concentration drug-making wastewater, has the advantages of simple equipment structure required by degradation, small unit volume and occupied area and the like, and has wide popularization prospects.

Description

technical field [0001] The invention relates to the technical field of drug treatment, in particular to a harmless drug treatment method. Background technique [0002] In the prior art, for the destruction of drugs, the main methods used at home and abroad are incineration or chemical neutralization, and based on this, various means are used to destroy drugs; but most of the existing processing methods used Both will cause certain pollution to the environment, and the pollutants will also damage groundwater resources. Therefore, it is necessary to find a green and non-toxic drug harmless treatment method using supercritical water to solve the burden and damage to the environment. important practical significance. [0003] There are many kinds of drugs found at present, which can be divided into three categories from the source of drugs: natural drugs, semi-synthetic drugs and synthetic drugs; natural drugs are drugs directly extracted from the original plants of drugs, such...
