[0002] Urban sewage treatment refers to a series of physical, chemical, and biological treatment processes to remove pollutants in sewage to protect the water environment and public health; the treatment process usually includes steps such as pretreatment, primary treatment, secondary treatment, advanced treatment, and sludge treatment; the purpose of pretreatment is to remove large particulate solids and floating objects, primary treatment removes suspended solids through sedimentation, secondary treatment uses biodegradation to remove organic matter, advanced treatment further improves water quality, and sludge treatment involves treating and disposing of the sludge generated during the treatment process.

[0003] Currently, when treating urban sewage by flocculation, generally, the flocculant and sewage are mixed by stirring. However, after the suspended solids in the sewage form large pieces of suspended solids under the action of the flocculant, due to their own gravity, the floating speed towards the water surface is slow, affecting the efficiency of urban sewage treatment and reuse. Based on this, a sewage treatment and reuse device is proposed. Content of the Utility Model

[0022] Embodiment

[0023] As Figures 1-4 shown, a sewage treatment and reuse device includes a recycling bin 1. A treatment chamber 2 and an impurity storage chamber 3 are arranged in the recycling bin 1. A fixing rack 4 is fixedly connected to the top of the recycling bin 1 where the treatment chamber 2 is located. A water supply pipe 5 is fixedly connected to the fixing rack 4. The water inlet end of the water supply pipe 5 is fixedly connected to a water pump, and the water pump is connected to the urban sewage water source. A water extraction pipe 6 is fixedly connected to one side of the recycling bin 1. A water pump is installed at the drainage end of the water extraction pipe 6, and the water extraction pipe 6 is connected to the treatment chamber 2. A medicine box 7 is fixedly connected to the side wall of the recycling bin 1. The medicine box 7 is filled with flocculant. A medicine adding pipe is fixedly connected to the top of the medicine box 7, and a medicine adding pipe 8 is fixedly connected to the bottom of the medicine box 7. An electric valve is installed in the medicine adding pipe 8, and the electric valve opens and closes regularly. The medicine adding pipe 8 is fixedly connected to the recycling bin 1, and the medicine adding pipe 8 is connected to the treatment chamber 2. A first impurity discharge pipe 11 and a second impurity discharge pipe 12 are fixedly connected to the bottom of the recycling bin 1. Solenoid valves are installed in both the first impurity discharge pipe 11 and the second impurity discharge pipe 12. The first impurity discharge pipe 11 is located below the treatment chamber 2, and the second impurity discharge pipe 12 is located below the impurity storage chamber 3. A motor 901 is fixedly connected to the top of the fixing rack 4. The output end of the motor 901 is fixedly connected to a rotating shaft 902. A reciprocating thread is arranged on the rotating shaft 902. A fixing ring 903 is fixedly connected to the rotating shaft 902 below the reciprocating thread. A stirring shaft 904 is fixedly connected to the bottom of the fixing ring 903. An air jet ring 905 is fixedly connected to the bottom of the stirring shaft 904. Air jet holes 906 are formed in the inner ring of the air jet ring 905. The air jet ring 905 is fixedly connected to the rotating shaft 902. The rotating shaft 902 penetrates through the fixing rack 4 and is rotatably connected to the fixing rack 4.

[0024] During use, urban sewage is added into the treatment chamber 2 through the water supply pipe 5 until the treatment chamber 2 is filled with urban sewage and the suspended solids and grease floating above the urban sewage can enter the impurity storage chamber 3. At this time, the water supply pipe 5 slowly adds urban sewage into the treatment chamber 2, while the water extraction pipe 6 extracts the treated urban sewage in the treatment chamber 2, and the amount of water extracted by the water extraction pipe 6 is the same as the amount of sewage slowly added by the water supply pipe 5, so that the suspended solids at the top of the urban sewage in the treatment chamber 2 can continuously flow into the impurity storage chamber 3. During the process of adding urban sewage, the electric valve in the chemical dosing pipe 8 will open to add flocculant into the urban sewage. At the same time, the motor 901 is started to drive the rotating shaft 902 to drive the fixed ring 903 and the jet ring 905 to rotate, and then drive the stirring shaft 904 to rotate to mix the urban sewage and the flocculant, so that the fine suspended solids in the urban sewage can agglomerate into large suspended solids under the action of the flocculant and float to the water surface, and automatically flow into the impurity storage chamber 3 during the process of the water supply pipe 5 slowly adding sewage into the treatment chamber 2. And during the process of sewage treatment and reuse, the electric valve in the chemical dosing pipe 8 will be periodically opened and closed to supplement flocculant into the treatment chamber 2;

[0025] When it is necessary to clean the recycling barrel 1, the solenoid valves installed in the first impurity discharge pipe 11 and the second impurity discharge pipe 12 are opened, so that the sediment in the treatment chamber 2 and the grease and suspended solids in the impurity storage chamber 3 are discharged through the first impurity discharge pipe 11 and the second impurity discharge pipe 12.

[0026] As Figures 2-5 shown, it further includes: a piston cylinder 1003 fixedly connected in the treatment chamber 2, a piston plate 1002 is slidably connected inside the piston cylinder 1003, a filter screen 1001 is fixedly connected to the top of the piston plate 1002, an exhaust pipe 1004 is fixedly connected to the bottom of the piston cylinder 1003, and one end of the exhaust pipe 1004 away from the piston cylinder 1003 is fixedly connected to a connecting ring 1005. Among them, the filter screen 1001 is slidably connected in the treatment chamber 2, an air inlet hole 1006 is opened on the recycling barrel 1, the air inlet hole 1006 is communicated with the piston cylinder 1003, and a one-way valve is installed in the air inlet hole 1006, so that the piston cylinder 1003 can only extract external air through the air inlet hole 1006. A one-way valve is installed in the exhaust pipe 1004, so that the air in the piston cylinder 1003 can only be discharged through the exhaust pipe 1004. The piston plate 1002 is slidably connected in the treatment chamber 2, the chemical dosing end of the chemical dosing pipe 8 is located below the filter screen 1001, the connecting ring 1005 is rotatably connected in the jet ring 905, and the rotating shaft 902 passes through the filter screen 1001 and is threadedly connected to the filter screen 1001.

[0027] During use, when adding urban sewage into the treatment chamber 2 through the water supply pipe 5, the urban sewage will be filtered by the filter screen 1001 before being mixed with the flocculant. During the rotation of the rotating shaft 902, the filter screen 1001 will reciprocate up and down in the treatment chamber 2 under the action of the reciprocating thread. During the downward movement of the filter screen 1001, the piston plate 1002 will slide downward in the piston cylinder 1003, causing the gas in the piston cylinder 1003 to enter the jet ring 905 through the exhaust pipe 1004 and be injected into the sewage through the jet holes 906. And during this process, since the jet ring 905 is in a rotating state, the air injected through the jet holes 906 can be fully contacted with the sewage;

[0028] It can enable large pieces of suspended matter aggregated in the sewage under the action of the flocculant to quickly move upward under the action of the air and reach the water surface. At the same time, when the air passes through the filter screen 1001, it can dredge the filter screen 1001. And since the filter screen 1001 is moving downward, the filter screen 1001 will squeeze the sewage, causing the sewage to pass through the openings of the filter screen 1001, enabling the suspended matter to quickly pass through the filter screen 1001 under the action of the gas and the downward movement of the filter screen 1001, preventing the blockage of the filter screen 1001, ensuring the quality and efficiency of sewage treatment, and thus ensuring the reuse efficiency of sewage;

[0029] When the filter screen 1001 moves upward, the piston plate 1002 will move upward along the inner wall of the piston cylinder 1003, causing the piston cylinder 1003 to draw in outside air through the air inlet hole 1006 and enter the piston cylinder 1003. This process repeats until the operation of urban sewage treatment and reuse stops.

[0030] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
