[0019] As Figure 1 and Figure 2A sewage treatment device based on activated carbon-based filter bed treatment is shown, including a chemical treatment tank 2 and an activated carbon-based filter bed treatment tank 3. The chemical treatment tank and the activated carbon-based filter bed treatment tank are arranged on a support base 1. The support base is suspended and supported by a number of support feet 15 provided at the bottom. The tops of the chemical treatment tank and the activated carbon-based filter bed treatment tank are both open. A first tank cover 4 is movably connected to the top of the chemical treatment tank. The first tank cover is connected to the chemical treatment tank through a lifting and rotating mechanism. A chemical addition port 7 is provided on the chemical treatment tank. A sealing cover is detachably installed at the feed end of the chemical addition port. A sewage inlet pipe is connected to the side wall at the upper end of the chemical treatment tank. The side wall at the lower end of the chemical treatment tank is connected to a liquid extraction pump 11 through a first conduit. The liquid extraction pump is fixed on the support base and is connected to a solenoid valve provided on the side wall at the lower end of the activated carbon-based filter bed treatment tank through a second conduit.

A U-shaped placement seat 20 is arranged in the activated carbon-based filter bed treatment tank. The upper end of the U-shaped placement seat is detachably connected to the second tank cover. The lower end of the U-shaped placement seat is located directly above the filter plate and is evenly provided with a number of first filter holes. An installation seat 21 for installing the activated carbon-based filter bed is arranged in the U-shaped placement seat. The upper end of the installation seat is detachably connected to the second tank cover. A gravel packing layer 22 is filled in the U-shaped placement seat below the activated carbon-based filter bed. The second tank cover is connected to a water pumping pipe 13 through a liquid collecting hood 31.

During operation, first, the sewage with a relatively low concentration is pumped into the chemical treatment tank. A repair chemical is added to the chemical treatment tank through the chemical addition port. The sewage is treated using the repair chemical. The water flow after chemical repair is sent into the activated carbon-based filter bed treatment tank through the liquid extraction pump. When all the water flow that needs to be repaired has entered the activated carbon-based filter bed treatment tank, the solenoid valve is closed to seal the activated carbon-based filter bed treatment tank. The water reuse pump connected to the water pumping pipe is started. This part of the water flow is filtered successively through the filter plate, the gravel packing layer, and the activated carbon-based filter bed, and finally is conveyed out through the water pumping pipe.

The sewage discharge port passes through the support seat along the second through groove. In the present utility model, large impurities filtered by the filter plate are retained in the activated carbon-based filter bed treatment box below the filter plate. First, start the first electric cylinder to make the sealing plug translate along the first rotating shaft, thereby opening the sewage outlet. Then, start the spiral conveyor motor and use the spiral conveyor blade to discharge the large impurities from the sewage discharge port. This design has the advantages of simple structure, convenient use, and practical and high efficiency.

[0023] As Figure 1The lifting and rotating mechanism shown includes a second mounting seat 8 fixed on the side wall of the chemical treatment tank, a second electric cylinder 9, a transmission plate 10, and a connecting frame 6. The second electric cylinder is vertically fixed on the second mounting seat, the output shaft end of the second electric cylinder is rotatably connected to one end of the transmission plate, and the other end of the transmission plate is connected to the first tank cover through the connecting frame.

The other end of the first valve body is fixed on the outer wall of the second valve body. There is a gap between the inner wall of the first valve body and the outer wall of the second valve body. A first through hole 19-2-2 communicating with the first valve body is opened at one end of the second valve body in the first valve body. The other end of the second valve body is open. The valve core is connected in a piston manner in the second valve body and is connected to one end of the second valve body extending into the first valve body through a spring. A second through hole 19-2-1 is opened on the side wall of the second valve body in the first valve body. The second through hole is sealed by the valve core. When the water flow cannot be pumped out from the activated carbon-based filter bed treatment tank continuously, the continuously working pump body will cause the internal and external pressure difference to increase continuously. At this time, the pressure protection valve will start automatically for protection. The utility model also provides a pressure protection valve. Through the self-protection function of the pressure protection valve, it can prevent the occurrence of structural damage caused by excessive internal and external pressure difference, reducing unnecessary losses.
