Embodiment 1

[0032] This embodiment provides a figure 1 The shown biogas power generation system by in-situ digestion and degradation of organic matter in the community includes a buffer tank 2, a mixing tank 3, a concentration tank 4 and an anaerobic digestion tank 5 connected in sequence; the feed port of the buffer tank 2 is connected to the community kitchen drainage main , the community kitchen drainage mains are respectively connected to the kitchen sewers in the community, and the kitchen sewers in the community are respectively provided with garbage breakers 1, and the mixing pool 3 inlet is connected to the outlet of the buffer pool 2 and the community The toilet flushing wastewater drainage main pipe is connected to each toilet 6 in the community. The upper part of the anaerobic digestion tank 5 is provided with an exhaust pipe, and the exhaust pipe is connected to the desulfurization tower 9 feed ports. The desulfurization tower The outlet of the tower 9 is connected to a gas in...

Embodiment 2

[0047] On the basis of embodiment 1, the present embodiment provides a resident community of 10,000 people, which produces 1.44 tons of excrement every day on average, 3.6 tons of kitchen waste, and 100 kg of green waste. figure 1 The specific implementation process of processing it is shown in the technological process.

[0048] The food waste of various companies is crushed by the food waste crusher 1 to form materials with a particle size of about 2mm, which is easier to hydrolyze. The food waste crusher 1 adopts a commercially available civil waste crusher; the processed food The kitchen waste is collected through the community kitchen drainage main and enters the buffer pool 2 for hydrolysis. The time is about 10 days, and the volume of the buffer pool 2 is 300m 3 about.

[0049] The hydrolyzed wastewater, toilet flushing wastewater and green waste are mixed in the mixing pool 3, the mixing time is about 6-12 hours, and the volume of the mixing pool 3 is 450m 3 about. ...

Abstract

The invention provides a community organic matter in-place digestion degradation biogas preparation electrical power generating system. According to the community organic matter in-place digestion degradation biogas preparation electrical power generating system, kitchen waste of each household in a community is smashed into small particle organic waste, and is mixed with toilet wastewater of each household and community green garbage, and high concentration waste water is obtained via concentration; the high concentration waste water is subjected to anaerobic digestion so as to obtain biogas and a digestion liquid; biogas is subjected to desulfuration purifying so as to obtain pure biogas, the biogas is used for generating electric energy via combustion in an internal combustion engine, and electric energy is recycled back to users in the community; the digestion liquid is treated so as to obtain a fertilizer and terminal waste water; and terminal waste water is subjected to simple treatment in septic tanks, and then is discharged into municipal sewage pipe networks. The community organic matter in-place digestion degradation biogas preparation electrical power generating system is capable of realizing pretreatment of waste sources, and in-place anaerobic digestion, so that technological process is short, treatment cost is low; kitchen waste is not stacked or transported, environment pollution is not caused, and transportation cost is reduced; and at the same time, electric energy generated by the community organic matter in-place digestion degradation biogas preparation electrical power generating system can be used, new energy policy subsidies from the government can be obtained, and economic efficiency maximization is realized.

Description

technical field [0001] The invention belongs to the technical field of energy and environmental protection, and in particular relates to a biogas power generation system by in-situ digestion and degradation of organic matter in a community and its application. Background technique [0002] At present, the organic waste treatment method in urban communities is that the kitchen waste is merged into the municipal waste into the waste treatment plant for incineration and landfill, and the toilet flushing sewage is discharged into the urban underground water pipe network and collected in the sewage treatment plant for treatment. On the one hand, this treatment method wastes the chemical energy of the organic waste itself, on the other hand, it increases the load of the garbage treatment plant and the sewage treatment plant, and increases the cost of organic waste during transportation. [0003] Chinese patent CN102167468B discloses "a combined treatment process of urban sludge, f...
