Problems solved by technology

[0008] Most of the above antibacterial agents are used in large-scale use due to high cost, poor antibacterial broad-spectrum or secondary pollution (such as hypochlorous acid, liquid chlorine, bromine, chloramine, chlorophenol, heavy metal salts, etc.), so they are used in garbage disposal. Site is rarely used for odor pollution control

Abstract

The invention relates to a bacterium inhibiting agent for controlling the pollutant gas emission during the household garbage collection and transportation process, preparation and applications thereof. The bacterium inhibiting agent is a plant extract, which is composed of the following raw materials: mint, galangal, Chinese honey locust, licorice, Sichuan Chinaberry fruit, and nux vomica. The bacterium inhibiting agent is made of pure plant extracts, has stable chemical and physical properties, is friendly to human and environment, and is pollution-free and non-dangerous. The bacterium inhibiting effect of terpane compounds, eugenol compounds, saponin, liquiritigenin, toosendanin, and alkaloid substances in mint, galangal, Chinese honey locust, licorice, Sichuan Chinaberry fruit, and nux vomica is utilized to effectively inhibit the bacteria in garbage, and the bacterium inhibiting agent has a very good effect on removing odors and sterilizing and disinfecting the air.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a bacteriostatic agent for controlling the discharge of polluted gas in the collection and transportation process of domestic garbage, and its preparation and application. Background technique [0002] With the development of the economy, the improvement of people's living standards, the growth of urban population and the expansion of urban areas, the amount of urban waste generation has increased year by year. Taking Shanghai as an example, the daily output of domestic waste in Shanghai exceeds 10,000 tons. Such a large amount of waste usually needs to be compressed and transferred before being collected and transported to the waste treatment plant. The process of compressing and transporting domestic waste, as the joint point connecting the source of waste generation and the terminal disposal system, is becoming more and more important, and it is an...
