The invention relates to the technical field of
sewage treatment, and discloses energy-saving and environment-friendly
sewage treatment equipment capable of automatically controlling the introduction amount of a reaction solution, which comprises a treatment tank body, a supporting seat is fixedly connected to the interior of the treatment tank body, a
rotating disc is rotatably connected to the outer surface of the supporting seat, and arc-shaped blades are fixedly connected to the outer surface of the
rotating disc; a pushing plate is movably connected to the interior of the arc-shaped blade, a compression spring is movably connected to the side surface of the pushing plate, an
extrusion column is movably connected to the side surface of the pushing plate, one end of the
extrusion column penetrates through the interior of the bag storage base, and an expansion base is movably connected to the position, located at one end of the
extrusion column, of the interior of the bag storage base. The rotating speed of the
rotating disc can be automatically controlled according to the introduction amount of
sewage, then the moving distances of the pushing plates in the arc-shaped blades are different, then the outflow amounts of
chemical reaction liquid are different, the
automatic control effect is achieved, waste is avoided, and certain cost is saved.
