This is the organic fertilizer, swill, leftovers, peels, vegetables, leaves and so on, which turns wet garbage into treasure.
When it comes to garbage, you will think of smelly swill and flying flies in restaurants, which is the impression of most people on kitchen garbage.
With the improvement of people's living standards, the amount of kitchen waste has gradually increased, accounting for about 30%-50% of urban domestic waste. How to deal with wet garbage, mainly kitchen waste, has become a new goal for researchers.
In so many cities in this country, there is no shortage of terminal treatment equipment for wet garbage. What's the difference between the products you developed?
Faced with our doubts, the engineers of Daming Puwei described the results of their visit and investigation-at present, there are some problems in garbage disposal, such as difficult deodorization, high energy consumption, secondary pollution and low efficiency. Specifically, high salt and high oil in garbage will lead to prolonged treatment cycle, which will easily produce odor and sewage and cause secondary damage to the environment.
After comparing and testing a lot of methods, we finally made our own "garbage disposal machine". Small machines can handle 150 kg of wet garbage, and it takes more than 4 hours to digest it, but at present, it takes nearly one day to treat it by similar methods.
We know that yogurt fermentation has a suitable time and temperature, and the fermentation of wet garbage also needs a formula. The device designed by them can fully mix the compound bacteria liquid with the kitchen waste at 60 to 80 degrees Celsius, thus achieving the purpose of low-temperature fermentation. At the same time, by vacuumizing, the fermentation process inside the equipment is in a high pressure range, which is convenient for the rapid fermentation of kitchen wet garbage.
The kitchen waste treatment device developed by Daming Puwei eats wet garbage. What are digestive products? The answer is fertilizer and pollution-free water. The author saw at the scene that Daming Puwei used garbage treatment equipment, and after nearly 5 hours of fermentation, 37 kg of garbage was converted into 1 1 kg fertilizer. "We control the water produced in the fermentation process within a certain range and finally discharge it from the atmosphere in the form of water vapor. Through the simple treatment of odor, the pollution to the environment is greatly reduced. " Engineer Daming Puwei said, "After experimental verification, the fertilizer produced after wet garbage treatment can promote plant growth; If it is made into pellet feed, it can feed economic insects and drive the follow-up industry. " After chatting with the author, I went to Hefei to attend an Expo with the wet garbage glycolysis treatment device in the kitchen.
At present, Daming Puwei's garbage disposal equipment has been well received by many parties. At present, the cost of treating wet garbage per kilogram is only 1.54 yuan, not counting the economic benefits brought by chemical fertilizer production. We hope that these "wet resources" will no longer be a burden on the environment, but will give back nutrients to nature. "
