Organic garbage treatment-energy regeneration combined device and organic garbage treatment method

Abstract

The invention discloses an organic garbage treatment-energy regeneration combined device. The organic garbage treatment-energy regeneration combined device mainly and structurally comprises an enzyme dissolving device, a microbial fuel cell device, a three-section-type biological membrane reactor and an ultrafiltration device. Sewage treated by the combined device can reach the national safety standard, and can be directly discharged or serve as reclaimed water to be reused. According to the invention, the problem that organic garbage is difficult to classify and treat is solved, and meanwhile, waste resource recycling for energy regeneration is realized.

Description

technical field [0001] The invention relates to a combined device for waste treatment combined with sewage treatment, in particular to a combined device for organic waste treatment and energy regeneration. [0002] The invention also relates to a method for treating organic waste by using the above-mentioned device. Background technique [0003] According to reports, the current per capita output of urban waste in China has reached 440 kg / year, and it will reach 352 million tons by 2010, and it will increase year by year. The problem of nowhere to pile up waste and cannot be disposed of is becoming more and more obvious. If proper plans are not adopted, residents will be seriously affected The daily life and production caused a series of serious problems. [0004] Organic waste accounts for more than 50% of urban domestic waste (such as kitchen waste, vegetable collection waste, etc.), and organic waste contains a lot of water (the highest water content of kitchen waste is ...

Problems solved by technology

[0003] According to reports, the current per capita output of urban waste in China has reached 440 kg / year, and it will reach 352 million tons by 2010, and it will increase year by year. The problem of nowhere to pile up waste and cannot be disposed of is becoming more and more obvious. If proper plans are not adopted, residents will be seriously affected life and production, causing a series of serious problems

[0004] Organic waste accounts for more than 50% of urban domestic waste (such as kitchen waste, vegetable collection waste, etc.), and organic waste contains a lot of water (the highest water content of kitchen waste is about 85%). Reduction, recycling, harmless

For example, using the incineration method to treat kitchen waste not only reduces the temperature of the incinerator, damages the furnace body, and reduces its service life, but also easily produces toxic dust particles such as dioxin during the incineration process, resulting in secondary pollution; the composting method is difficult to treat organic waste. , the composting process is uncontrollable, the garbage is easily corrupted, the resource utilization rate is low, and it is difficult to obtain the required fertilizer; the landfill method can be used to dispose of organic waste, which can be decomposed under the action of microorganisms to achieve the reduction of waste, but During the landfill process, the garbage will rot and smell, breeding mosquitoes and other vectors, affecting the surrounding environment and polluting air and water sources

[0005] Nowadays, the more mature organic waste treatment schemes are nothing more than the use of anaerobic fermentation and ecological biological chain method, but the process operation is difficult, the operation cycle is long, and the operation process has serious pollution to the surrounding environment, so it is difficult to reduce waste conveniently and quickly.
