[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 s

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 ...
