The invention discloses an environment-friendly
sewage treatment device, which belong to the technical field of
sewage treatment, the problems that when
sewage treatment is carried out,
impurity filtration cannot be carried out step-by-step , clogging is easily generated, a
grating plate is not easy to replace and impurities are not easy to clean are solved. Technical key points are that: the device is characterized by comprising a
sewage treatment tank and a filter
grating plate, the upper side of one end of the
sewage treatment tank is connected with a water inlet
pipe; a water outlet
pipe is connected below one end of the
sewage treatment tank; a filtering
grating plate is mounted in the sewage treatment box; the filter grating plates are provided with filter holes, the filter grating plates divide the interior of the sewage treatment box into a plurality of filter cavities, the filter cavities are internally provided with
sludge discharge assemblies, and by arranging the drawing type filter grating plates, sewage can be conveniently filtered step by step, the filter grating plates can be conveniently assembled and replaced, and the operation is convenient and fast; impurities and
sludge can be conveniently pumped out through a blow-off
pipe, impurities attached to the surface of the filtering grating plate can be conveniently scraped away, and filtering holes are preventedfrom being blocked.
