The invention discloses a
system and process for micro-power
sewage treatment in a
plateau environment. The
system includes a tank body, wherein the tank body is arranged on a low-temperature
antifreeze layer on surface of the
plateau, the tank body is provided with a functional
pool, and the functional
pool includes an anaerobic
pool, an anoxic pool, an aerobic pool, a
sedimentation pool and a purification tank. The process comprises the steps: selecting a lighting environment, adopting a good lighting zone in the
plateau environment as the selected zone, performing digging so as to form an installation pit under the surface of the selected plateau zone, installing a
solar power supply device on the ground surface, introducing
sewage from the anaerobic pool, adding matched composite
nitrifying bacteria according to the characteristics of the
sewage, guiding the sewage to flow through the entire
system, finally discharging the sewage from the purification pool, and heating the sewage inside the tank body through a
heating element so as to maintain the temperature at 15-25 DEG C. The invention aims to solve the problems of inconvenient
sewage treatment, high cost,
high energy consumption and no suitability for wide and sparsely-populated areas in the plateau environment are solved.
