The utility model discloses a micro-power domestic
sewage treatment device which comprises an
oil separation area, a septic area, an anaerobic area, an aerobic area, a clear water recycling area, an
aeration device arranged at the aerobic area and a solar device for supplying power to the
aeration device, the kitchen washing
oily wastewater is used for irrigating farmland crops after passing through the
oil separation area, the septic area, the anaerobic area, the aerobic area and the clear water recycling area; the septic zone comprises at least three continuous cells, namely a first
cell, a second
cell and a third
cell, the first cell is communicated with the
oil separation zone, and the third cell is communicated with the anaerobic zone; the first cell is further communicated with a flushing side
sewage pipeline, and the third cell is further communicated with a washing water and
bathing water collecting
pipe. Through
continuous treatment of the oil separation area, the septic area, the anaerobic area and the aerobic area, organic matters and nutritive salts in
sewage are effectively removed, the biodegradability of the sewage is improved, the treated clear water can be used for farm
irrigation, and the cyclic utilization of
water resources is realized.
