The invention discloses a
sewage treatment apparatus, which comprises a valve, a steam pipeline, a spraying head, a
flue gas
discharge pipe, a cover, a furnace, an
evaporation panel, gas inlet holes,a stove head, an annular support, a total
pipe and a water pump, wherein the opening on the top portion of the furnace is fixedly connected to the cover through a
flange structure, the
evaporation panel is arranged inside the furnace, and is tapered, the edge of the
evaporation panel overlaps on the annular support welded on the inner wall of the furnace, the stove head for heating is arranged below the evaporation panel, and is connected to a fuel
system by a pipeline, a plurality of the gas inlet holes for supplying air for
combustion are arranged at the bottom portion of the furnace, and one end of the
flue gas
discharge pipe is welded at the through hole position on the middle portion of the evaporation panel. According to the present invention, the water can be rapidly sprayed to thehigh-temperature evaporation panel by the spraying head so as to rapidly produce high-temperature steam while the water is changed into steam, and the internal particles and inorganic substances are precipitated, such that the efficient
sewage treatment can be achieved without the adding of the compound.
