Specific embodiment
With reference to the accompanying drawing and the utility model is described in detail in specific embodiment.
The utility model provides a kind of rural sewage treatment system, as shown in Figure 1, including inlet well 1, in inlet well 1
It is provided with sewage pump, the water outlet of sewage pump is connected with oxidation ditch 2 and sedimentation basin 3, oxidation ditch 2 in turn by pipeline
Being of coupled connections has microbiological fuel cell, and aerator 5 and two impellers 4 are provided in oxidation ditch 2, and two impellers 4 are distinguished
Close to the water inlet of oxidation ditch 2 and the water outlet of oxidation ditch 2, impeller 4 and aerator 5 are connected to microorganism combustion by conducting wire
Expect battery, sludge reflux pump, sludge reflux pump and oxygen are connected with by pipeline between the sludge outlet and oxidation ditch 2 of sedimentation basin 3
Change and sludge dewatering workshop is also connected with by pipeline in the connecting pipe between ditch 2.
Microbiological fuel cell includes the carbon felt electrode 6 in oxidation ditch 2 and the battery 7 outside oxidation ditch 2, is stored
Battery 7 is connect by conducting wire with carbon felt electrode 6, and impeller 4 and aerator 5 are connect by conducting wire with battery 7.
Microbiological fuel cell (MFC) in a kind of rural sewage treatment system of the utility model is with microorganism for catalysis
Chemical energy is directly translated into the device of electric energy by agent, again can convert biological energy source potential in sewage while purifying sewage
It is used for electric energy, reduces water factory's processing cost；Electric flocculation processing is carried out using aerator 5, principle is to be powered on outside
Using water as electrolyte in the case where source, on the one hand hydroxide ion of its electrode in electrolysis Shi Huiyu water, which combines, plays coagulation
