Household garbage bioreactor and aerobic-anaerobic-semi-aerobic circulation treatment method

Abstract

The invention discloses a bioreactor, which comprises a reactor, a horizontal perforation ventilation pipe, a vertical perforation ventilation pipe, a percolate adjusting tank, a percolate discharge guide pipe, a water seal tank and an air collection cover. The horizontal ventilation pipe is installed at the bottom end inside the reactor, and two ends of the horizontal ventilation pipe are both communicated with the external. One end of the vertical ventilation pipe is communicated with the horizontal ventilation pipe, and the other end of the vertical ventilation pipe is communicated with the external. A submersible sewage pump is arranged in the percolate adjusting tank, a water outlet of the submersible sewage pump is communicated with a water distributor through a percolate recharge pipe, and the water distributor is arranged at the top of the reactor. One end of the percolate discharge guide pipe is communicated with the bottom of the reactor, the other end of the percolate discharge guide pipe is communicated with the percolate adjusting tank, and an outlet of the percolate discharge guide pipe is located above the highest water line of the percolate adjusting tank. The percolate discharge guide pipe, the percolate recharge pipe and the horizontal ventilation pipe are respectively provided with a switch valve. The water seal tank is arranged at the upper end of the reactor, and air collection cover is installed on the water seal tank and covers the opening end at the top of the reactor, and an air discharge port is arranged on the air collection cover. An aerobic-anaerobic-semi-aerobic circulation treatment method of household garbage is further disclosed.

Description

technical field [0001] The invention relates to the technical field of domestic waste treatment devices, in particular to a bioreactor and a domestic waste aerobic-anaerobic-quasi-aerobic cycle treatment method. Background technique [0002] With the development of the economy and the acceleration of the urbanization process, the output of urban domestic waste is increasing day by day. The phenomenon of garbage siege forces people to pay attention to the treatment of urban domestic waste very early. At present, sanitary landfill, incineration and composting have been formed. Large-scale conventional treatment technology for domestic waste. However, the pollution and treatment of rural domestic waste has not received enough attention, resulting in a serious lack of treatment methods and technologies for rural domestic waste. [0003] Sanitary landfill is currently the main treatment method for urban domestic waste. This technology mainly relies on the action of microorganism...

AI Technical Summary

Problems solved by technology

However, the current urban domestic waste treatment technology is not only expensive, but also large-scale and highly intensive, which cannot adapt to the characteristics of relatively low rural economic level, relatively small domestic waste production, and scattered discharge.
