Ji'nan city sanitation scientific research institute. In 2015, the city of Ji'nan produced 4740 tons of domestic waste, of which 3639 tons of municipal solid waste in urban and Jiyang county were all shipped to the second living waste comprehensive treatment plant in Ji'nan and its incineration plant and its The sanitary landfill is disposed of harmlessly, 70% of which is used for incineration. The remaining thousand tons of garbage will be sent to landfill sites in Zhangqiu, Pingyin and Shanghe respectively.
according to the annual growth rate of 3.5%, the daily output of garbage in the urban area in 2020 will reach 4166 tons, nearly 700 tons more than it is now. Gao said that Ji'nan's urban domestic waste is not classified as mixed garbage, and food waste accounts for nearly 60% of the total. Different from the past, the water content of garbage now is about 80%. Before the incineration process, it is necessary to increase working procedures and reduce the water content of refuse by compressing.
reporter found that there is only one living garbage disposal plant used 6 years ago in Ji'nan, which was once known as the largest waste incineration power generation project in the country, and the amount of disposal was about 2600 tons on incineration and landfill day. Now, the daily waste of more than 3600 tons has made the sole treatment plant overrun, and some refuse is difficult to deal with effectively.
in the face of increasing waste, 4 years ago, Ji'nan tried to classify garbage. In 2012, the four color garbage classification method was conducted in the calendar. According to public reports, the district finance set up special funds for garbage sorting work, not less than 5 million yuan per year. However, due to the classification of human machine garbage and the poor classification effect, the classification work was suspended in March 2015.
the next step will determine the five grade method of garbage disposal
it is understood that in 2015, Ji'nan city city management department and a waste clothing recycling company, in succession in the city's residential community set up 520 special collection boxes, residents voluntarily put in, the company can collect about 2 tons of waste clothing on average daily. All these waste clothes are transported to the Wuxi production base for production, recycling and reuse. The head of the company said.
food waste accounted for a large proportion, and easy to become the main reason for the two pollution in storage, transportation and disposal. In this regard, at the end of 2015, the urban management department carried out the pilot work on the comminution of household organic waste in the community of Jinxiu Street office in Huaiyin District, Huaiyin District Office of Xing Fu Street, and set up a unified household kitchen waste crusher for 250 households and cultivate the habit of smashing organic waste in place. At present, the pilot work of classification is being pushed forward, and the reduction rate of rubbish is over 40%.
in order to eliminate food waste, a Zhangqiu technology company also demonstrated the use of cockroaches (cockroaches) to convert kitchen waste into protein feed. After cockroaches eat waste, they produce organic fertilizer. At present, the project runs in Zhangqiu, and it can handle 20 tons of kitchen waste on a single day. It is expected to be implemented in the urban area in the first half of next year.
in the future, how does Ji'nan continue to classify garbage? The responsible person in charge of the municipal sanitation research institute will introduce the next step to determine the five grade method of garbage disposal. That is, garbage disposal can be divided into five levels: source reduction, direct utilization, indirect utilization, energy utilization and landfill disposal. Direct use is to establish the relevant channels to make use of the direct use of waste, such as furniture, wine bottles, electrical appliances and so on, which can be used directly to improve the utilization rate of metal, newspapers, organic materials and so on, to reduce the consumption of material.
