The invention relates to a solar
micropower buried integrated
sewage treatment device and belongs to the field of
water treatment equipment. The device comprises an overground device and an underground device, wherein the overground device comprises a solar plate and a solar equipment box; the underground device comprises a housing, wherein a water inlet and a water outlet are formed on two sides of the housing;
sewage enters into the housing from the water inlet, sequentially passes through a baffling adjusting region, a
facultative anaerobic
precipitation region, a buffer region, an aerobic zone, a secondary
settling region and a water outlet pond and finally flows out from the water outlet. Aerobic zone filler is suspended in the aerobic region, a solar
micropower aerating
system is arranged at the bottom of the aerobic zone, and the operating power of the solar
micropower aerating
system is provided by the solar plate. According to the technical scheme, the problem that in a rural
sewage treatment process, a
power grid is not perfect, sewage is hard to centralize and equipment is inconvenient to maintain is solved, and meanwhile, the housing of the equipment can be directly buried underground, so that the actual occupied area can be greatly reduced, and the device has beneficial technical effects and remarkable practical value.
