Composite organophosphorus degrading enzyme emergency rescue decontamination agent application and preparation method thereof

Abstract

The invention discloses a composite organophosphorus degrading enzyme biological decontamination agent for emergency rescue and decontamination operation at chemical disaster accident environmental scene. The decontamination agent mainly consists of organophosphorus hydrolase, organophosphorus anhydride hydrolase, diisopropyl fluorine phosphatase, organochlorine degrading enzyme and trehalose, wherein all the components reach the following contents in percentages: 80-90% of organophosphorus hydrolase, 3-5% of organophosphorus anhydride hydrolase, 2.5-3% of diisopropyl fluorine phosphatase, 5-10% of organochlorine degrading enzyme and 0.5-1% of trehalose. The decontamination agent has the following advantages: compared with traditional chemical, physical and mechanical decontamination modes, the composite organophosphorus degrading enzyme biological decontamination agent has such advantages as no poison, no corrosion, high catalysis efficiency, low use level and wide application range, can be used for decontamination and disinfection for staff, clothes, equipment, soil and water sources polluted by organophosphorus, organochlorine and sulfides, in particular, is suitable for emergency rescue and decontamination in pesticide leakage accident scenes, and cannot cause secondary environmental pollution.

Description

technical field [0001] The invention relates to a compound enzyme-based biological decontaminant for emergency rescue and decontamination at the scene of a chemical disaster accident environment. To be precise, it is an application of a compound organic phosphorus-degrading enzyme emergency rescue decontaminant. It is a major emergency rescue measure to eliminate the toxic hazards of infected bodies and contaminated areas. Background technique [0002] Hazardous chemical leakage and other accidents occur from time to time due to factors such as natural disasters, survey and design defects, improper use of equipment, illegal transportation, terrorist attacks, local wars, etc., which seriously threaten the lives of the people, cause huge economic losses, and damage the ecological environment. If it is damaged, it will also affect social stability. For example, the Tokyo subway "sarin gas incident" in Japan in 1995, and the "biochemical weapon incident" in Syria in 2013. In r...

AI Technical Summary

Problems solved by technology

For example, mechanical decontamination and physical decontamination methods are difficult to detect, have many ways of injury, sudden and rapid spread of hazardous chemical disasters. It is also difficult to implement rescue, and may cause poisoning of combatants and serious environmental damage. Pollution

In the chemical decontamination method, special attention should be paid to whether the chemical reaction between the decontaminant and the poison produces new toxic substances to prevent the reaction from happening again. The implementation of chemical decontamination in poisoning accidents requires the use of equipment and consumes a large amount of decontamination agents, so the cost of use higher
