Food waste is high in water content and oil content, and it is perishable and stinky. If it is not treated in time, it will affect the surrounding environmental sanitation. At the same time, in the process of cleaning and transportation, it is easy to occur such as leakage and difficult to clean up. Recently, a digester machine was installed in a commercial district in Chengdu have attracted the attention of many netizens because it can treat food waste on site and decompose it into water.

 

On December 10, the reporter came to the business district to find out. The reporter saw on the second basement floor of the business district that the digester machine covered an area of ​​more than 10 square meters. There is a control panel on the outside, which shows the temperature in the machine and the weight of the food waste. Mr. Wen Ke, the person in charge of the disgester machine of an environmental protection company in Chengdu, introduced the machine on October 1, 2019, which handles an average of 1.3 tons of food waste per day. Up to now, dispose of more than 70 tons of food waste.

​

Mr. Wen Ke, said: "If you deal with original food waste, including oil and water, the maximum load is 4 tons per day. In accordance to the different components of the food waste , It has processing cycles, overall usually within 24 hours, all the organic waste will be completely digested. Therefore, our machine can digest all the food waste from shopping malls and complexes daily."

 

Mr. Wen Ke told reporters that the machine uses biological hydrolysis as the core and divides the treatment of food waste into three categories: pretreatment system, biochemical treatment system and water treatment system. The operation of the machine is simple and convenient. The staff only needs to collect the food waste, and then dispose it into the machine, and the machine will automatically complete the treatment.

​

Mr. Wen Ke, said: "After collecting the food waste, the three items of oil, water, and slag are completely separated. The oil is collected and processed by a qualified company for further processing. The separated water and slag are transferred to the degradation equipment, and through the biological bacteria, mimic the digestive function of the animal's stomach, digest all the organic matter, and turn into water and carbon dioxide. If the water enters the water treatment equipment again, it will pass the water treatment. After the equipment (treatment) has reached the municipal level III pipe discharge standard, it enters the municipal sewage pipe network. "

 

Mr. Wen Ke said that the equipment is suitable for use in places where food waste is concentrated in commercial complexes, large hotels, and residential communities, but because the machine is only suitable for the degradation of organic waste, workers' preliminary sorting is essential. He hopes that through the implementation of garbage classification, automatic collection, transportation and disposal of food waste can be realized in the future.

 

Mr. Wen Ke,said: "The direction is to build a platform that integrates the collection, transportation, and processing from the initial intelligent trash can to intelligent collection and transportation and intelligent processing. This will make it easier to monitor from the source of the food waste to the place where it processed."
