Suzhou Hongben: Garbage sorting out of the characteristic road

Suzhou Hongben: Garbage sorting out of the characteristic road

Kunshan Development Zone implements garbage classification, and has made great efforts in technological innovation and service innovation. Through the promotion of garbage classification, it can reduce the amount of garbage, avoid potential pollution and protect the ecological environment. Comprehensive utilization of garbage can produce new products, promote resource recycling, and obtain higher economic benefits. The implementation of garbage classification is related to the formation of green development methods and lifestyles.

The perishable wastes such as leftovers, leftovers, egg shells, melon and fruit peels, tea residues, etc. discarded in the daily life of residents are collectively referred to as kitchen waste. kitchen waste treatment plant. Since Changchun City became a pilot city for the classification of domestic waste, Kunshan Development Zone has actively established a waste treatment system of classified delivery, classified collection, classified transportation and classified disposal to comprehensively promote the classification of domestic waste.

At present, the kitchen waste terminal disposal center of Kunshan Development Zone realizes the classified delivery, classified collection, classified transportation and classified disposal of domestic waste, and promotes the specific work of "integration of the two networks" of domestic waste classification and renewable resource recovery. The waste treatment system is comprehensively transformed and upgraded to the current status of renewable resource recycling in Kunshan Development Zone, scientifically planning a one-stop mobile and convenient recycling point, integrating renewable resources in the entire region, and realizing the overall upgrading of the renewable resource industry through a variety of high-tech technical means, providing the best for the region Garbage sorting work provides overall data and analysis reports.

In order to turn kitchen waste into treasure, the biological fermentation treatment process is adopted. It is understood that the organic waste treatment equipment adopts biological bacterial fermentation treatment. In an aerobic environment, microorganisms are used to convert the organic matter in the organic waste into the organic matter used by plants. fertilizer. In the fermentation chamber, the fermentation temperature is between 50°C and 60°C. By controlling the ventilation and moisture in the fermentation chamber, the organic waste is biodegraded. During the fermentation process, biological bacteria and biological enzymes are added to maximize the organic waste. Decompose and eventually ferment organic fertilizers. For these organic fertilizers, Kunshan Development Zone Kitchen Waste Terminal Disposal Center has signed a preliminary cooperation intention with the environmental protection department. In the early stage, green plant cultivation experiments were carried out. Through the ratio of organic fertilizer and flower soil, it was finally possible to plant green plants and Survival, after many experiments, we have mastered the blending ratio of organic fertilizer and flower soil. Due to the different kitchen waste generated on the dining table of residents in different seasons, the final fermented organic fertilizer has different nutrients. According to different ratios, it is also summarized. Some experiences provide data support for future large-scale promotion.

It is said that garbage is treasure in the wrong place, and garbage sorting is a process of turning waste into treasure. For agricultural production, kitchen waste is rich in organic fertilizers after treatment, and it is a good assistant for the development of green agriculture. The proposal of "garbage classification, returning organic fertilizer to the field" combines the garbage classification in daily life with high-standard farmland construction and green planting.

"In addition to households, factories, enterprises, schools, hotels and other units generate kitchen waste every day. Crops that are too late to be harvested in rural areas and prolifera at sea can be re-invested in agricultural production after recycling." Organic composting Returning to the field conforms to the laws and laws of nature, and realizes the recycling of organic waste resources in farmland.
