It was received in 5 minutes!"Change" organic fertilizer in wet garbage is very sought after

The Yangtze River Daily Da Wuhan Client July 6th (Reporter Gong Ping) "Without 5 minutes each time, many colleagues report that fertilizer is easy to use, flowers and vegetables are particularly suitable, and some people come to lead!" Recently, Wuhan, Wuhan The relevant person in charge of the Municipal Natural Resources and Planning Bureau told the Yangtze River Daily reporter that the wet garbage in the unit of the unit was placed on a demonstration station on the ground. After more than half a year of operation, the response was good. A new exploration of cyclic use.

Recently, the reporter saw the "Wet Rown Treatment Demonstration Station" in the Courtyard of the Municipal Natural Resources and Planning Bureau. The demonstration station was located in a corner near the cafeteria. In front of the pavilion, there is a "smiley face" composed of vertical green plants. The display on the background shows the weight information of the daily and monthly fertilizer. Several meters apart are pre -processing equipment.

The processing process is simple. First, pour the kitchen waste from the cafeteria into the pre -processing equipment for crushing and filtering water, and enter the degradation machine after pre -processing; the equipment is automatically operated, and the effect of special bacteria shall be used. Dowt the wet garbage into organic fertilizer base materials within 24 hours; when the biodegradation of more than 80%of the material in the biodegradation machine, open the material warehouse door and start "stirring and reverse", and automatically produce. The organic fertilizer after the discharge is placed naturally for more than two weeks. After mixing with the soil 1: 5, it can be used as a green soil and planting flowers and fruits.

According to the relevant person in charge, the natural placement time is calculated, about once every two weeks of fertilizer, which can be distributed about 40 bags. Each time it is distributed, colleagues actively queue up to collect. Preliminary estimates that 100 kg of wet garbage produces about 20 kg of organic fertilizer, which has changed slightly according to the garbage content, and there is no other waste.

Wet garbage is the main source of odor produced by urban waste transfer stations. The conventional method is to be dragged away every day. Looking for a more suitable "local" processing method.

At the end of last year, the Municipal Natural Resources and Planning Bureau and the Municipal Urban Management Law Enforcement Committee launched the "Wuhan Wet Garbage Demonstration Facilities Application Demonstration and Promotion Research" project, exploring a new way to make wet garbage "become a treasure" nearby. In order to deeply understand the effect of new technologies to dispose of wet garbage, the bureau is one of the demonstration sites, and the processing equipment is introduced for field data collection.

In half a year, in addition to using the instrument to regularly detect the noise and odor generated by the equipment, the research team also set up evaluating the QR code to actively go to the offices with relatively closer distance from the device, and ask my colleagues to "scan the code" one by one to fill in the actual experience.

The survey results show that in the range within one meter of the equipment, some colleagues reported that they could hear the sound of the machine equipment. Within a little farther range, it generally indicated that there was no noise or odor effect.

The reporter interviewed at 12:30 noon on the day, and the equipment started from time to time. Standing in one meter line, he felt that the sound was not harsh; the kitchen waste and organic fertilizer treatment area did not smell obvious odor.

The reporter interviewed several staff who had received fertilizers. Mr. Peng told reporters that when he distributed fertilizer at the demonstration station last week, he specially helped the neighbors of the neighborhood to receive a few bags and did not feel odor. "I have used fertilizers for neighbors, they feel particularly good, and please ask me to take it again." Ms. Yan also said that friends who love to grow flowers and plant vegetables reported that this organic fertilizer is particularly suitable for the balcony planting in the home, which is better than the chemical fertilizer sold outside. Essence "Every time I distribute fertilizer is quite sought -after, I can't get it late."

According to the relevant person in charge, the research project also tracked the operating data of more than 20 other application points in the city in the same way in order to collect the actual data of the efficient processing of urban wet garbage. Developing wet garbage "locally disposal" in conditions where conditions permit not only reduce the pollution generated by transportation, reduce costs, and produce organic fertilizer can also be used for garden landscapes to achieve recycling of resources.

Considering that the processing equipment must not only be practical but also beautiful. To this end, the project also carried out the "Wuhan Wet Garbage Treatment Equipment Maintenance Facilities Design Scheme Collection" activity at the end of last year to carry out 64 design schemes, and rewarded the best schemes through online voting and expert selection through online voting and expert selection. After the event, the integration of excellent plans to form a reference for the design of the "Wet Wet Trash on Wet Garbage Treatment Equipment for Wet Garbage", which provides design guidelines for units and communities that need to build wet garbage in the future.

It is reported that the project plans to track research and equipment upgrades in one year, and finally form an application evaluation report to find the best solution for urban wet waste treatment to help the city's refined management level improvement.
