The invention pertains to the technical field of environment protection, and particularly relates to a simple
sewage treatment device of an alternate
aeration basin and a treatment technique thereof, wherein the treatment device comprises the
aeration basin, an aerator, a water inlet pipeline, a water outlet pipeline, a
sludge discharge pipeline, a communicating pipeline and a control valve. In implementation, a natural pond or flat field in the downwind direction in a built-up area of villages and towns is selected, and the alternate
aeration basin is formed by excavation and mounding; an impermeable membrane is laid around the alternate aeration basin, bricks are laid on the impermeable membrane after the communicating pipeline, the water inlet pipeline, the water outlet pipeline and the
sludge discharge pipeline are installed, and
cement mortar is plastered, thus completing the construction of the basin body. Then, the aerator or a mixer, an electric /
pneumatic valve and the
control system are installed, and then the
sewage treatment device can be put into service and used. The
sewage treatment device adopts a timing
control mode of set time or a mode of online feedback real-
time control for
sewage treatment. The
sewage treatment device has high treatment efficiency, small occupied area, and has low
capital investment and short construction cycle compared with UNITANK and alternative oxidation ditches of three ditches; and through matched set time or real-
time control of operation, the
system can be suitable for shifty
water quality and quantity of sewage in villages and towns, and can runs automatically.
