Under the operation of Wang Xinping, an environmental engineer of Mindray, an equipment research and development unit, the four water outlets and several large trash cans below slowly rose. There is an underground trash can corresponding to each classified throwing port on the ground, and each trash can has a capacity of 660 liters. Four trash cans can meet the needs of a small community with about10.5 million people.
It is understood that buried garbage collection equipment also has many intelligent functions. For example, when the volume or weight of garbage reaches 85%, the trash can will send out a pickup alarm and push the pickup information to the management, and will stop responding when it reaches 95%; When the equipment senses that smoke is generated in the trash can or the temperature is too high, it will automatically extinguish the trash can; When a living thing falls into the trash can, the life detector will give an early warning to remind the manager at the first time; Design rainwater pipe groove around the equipment to prevent rainwater from entering the trash can and causing mixed flow of rain and sewage; The trash can is also equipped with a biological deodorizing device, which automatically sprays deodorizing liquid every once in a while to react with garbage odor molecules, so as to deodorize and prevent odor from overflowing.
The system can set the working time, intensity and frequency remotely and work automatically.
In the past, there was a problem of low utilization rate of biocides caused by splashing in garbage disposal stations. After the outbreak of COVID-19 epidemic, Mindray Environment has successfully launched the latest disinfection and epidemic prevention function recently through intensive research and development and debugging. Wang Xiaobin, director of Mindray's environmental research and development, introduced that the equipment is based on the closed space of buried barrels, atomized into tiny particles of 10- 100 micron with broad-spectrum biocide, which can be sprayed in the underground closed space regularly to kill germs in the air and garbage. It is worth mentioning that the disinfection system can also set the working time, intensity and frequency remotely to work automatically according to the needs of epidemic prevention, and prompt the disinfectant supplement in time.
According to the Guidelines for Preventive Disinfection of novel coronavirus Infected with Pneumonia in Sanitation Industry issued by Shenzhen Urban Management Department, garbage collection containers such as FRP plastic trash cans and small garbage houses need to be cleaned and collected twice a day, washed with water once a day and disinfected with disinfectant. When working, sanitation workers need to wear work clothes (or protective clothing), masks and gloves, and wash their hands and change their work clothes in time after the operation is completed. Wang Xiaobin said that burying trash cans is safer, more economical, more efficient and more sustainable than traditional methods, and it can save about 70% of biocides.
It is understood that more than 20 such buried garbage disposal facilities have been installed in Shenzhen. Wang Xiaobin revealed that the free upgrade of Shenzhen facilities will be completed within one week, making them all have the functions of disinfection and epidemic prevention. "The key epidemic prevention sources of garbage will be safe and harmless, providing citizens with a more fashionable and healthier living environment."
