The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0018] The first embodiment of this application is:

[0019] See also Figure 1 and Figure 2 ,in, Figure 1 It is a schematic diagram of the overall structure of the deep denitrification sewage treatment device of the first embodiment of the present utility model. Figure 2 It is a cross-sectional schematic diagram of a deep denitrification sewage treatment device according to the first embodiment of the present invention. The present invention provides a deep denitrification sewage treatment device, comprising a collecting box 101, a processing chamber 102, an adjusting chamber 103, a sedimentation chamber 104, a spraying assembly and a drug dispensing assembly, wherein the spraying assembly comprises a connecting rod 105, an extension rod 106, a nozzle 107, a rotary joint 108 and a power component, wherein the power component comprises a worm 109, a worm gear 110 and a power motor 116, and the drug dispensing assembly comprises a medicine box 111, a positioning groove 112, a stirring motor 113, a stirring rod 114 and an auxiliary rod 115. The above-mentioned solution solves the problem that the sodium hypochlorite sprayed from the existing sewage treatment deep denitrification device may not be evenly distributed in the entire adjusting chamber 103 due to the fixed position of the nozzle 107, thereby affecting the overall denitrification effect. It is understandable that the above-mentioned solution can also be used to solve the problem of uniform stirring.

[0020] According to this specific embodiment, the treatment chamber 102 is connected to the collection box 101, the regulating chamber 103 is connected to the treatment chamber 102, and the sedimentation chamber 104 is connected to the regulating chamber 103. The collection box 101, the treatment chamber 102, the regulating chamber 103 and the sedimentation chamber 104 are arranged using the sewage treatment principle disclosed in the announcement number CN218755297U. They are connected by a water pump and a hose, and the water pump is used to provide power for the circulation of sewage. A net is set in the collection box 101 to achieve preliminary precipitation, and adsorption materials such as activated carbon, coal, and ion exchange resin are set in the sedimentation layer for adsorption after secondary denitrification, so as to achieve better treatment effect.

[0021] Among them, the connecting rod 105 is rotatably connected to the regulating chamber 103 and is located inside the regulating chamber 103, the extension rod 106 is communicated with the connecting rod 105 and is located inside the regulating chamber 103, the nozzle 107 is connected to the extension rod 106, the rotary joint 108 is connected to the connecting rod 105, the power component is connected to the connecting rod 105, and the drug dispensing assembly is arranged on the processing chamber 102. The sodium hypochlorite solution is placed in a container, and the container is connected to the rotating nozzle 107 through a hose. Pressure is applied to the container, so that the sodium hypochlorite solution enters the connecting rod 105 through the hose and the rotating joint 108, then flows to the extension rod 106, and finally is sprayed out through the nozzle 107. There are multiple extension rods 106, and multiple extension rods 106 are provided with multiple nozzles 107 to expand the range of solution spraying. At the same time, the power component can drive the connecting rod 105 to rotate, and then the extension rod 106 rotates accordingly, playing a role of stirring and mixing. Moreover, due to the design of the rotating joint 108, it will not affect the delivery of external sodium hypochlorite solution.

[0022] Secondly, the worm gear 110 is fixedly connected to the connecting rod 105 and is located above the regulating chamber 103. The worm 109 meshes with the worm gear 110. The output end of the power motor 116 is connected to the worm gear 109. When the power motor 116 is powered on, it drives the worm gear 109 to rotate, which in turn drives the worm gear 110 to rotate, and thus the connecting rod 105 to rotate.

[0023] At the same time, the positioning groove 112 is fixedly connected to the processing chamber 102 and is located at the top of the processing chamber 102; the medicine box 111 is connected to the interior of the processing chamber 102 and is placed in the positioning groove 112. The medicine box 111 is used to place Mg-containing 2+ and PO4 3-The medicine box 111 is placed in the positioning groove 112, and a gravity sensor is provided at the bottom of the medicine box 111. According to the detection of the gravity sensor, the opening of the valve is controlled to control the amount of medicine added, which is beneficial to improving the sewage treatment effect.

[0024] In addition, the stirring rod 114 is rotatably connected to the processing chamber 102 and is located within the processing chamber 102. The output end of the stirring motor 113 is connected to the stirring rod 114. The auxiliary rod 115 is fixedly connected to the stirring rod 114 and is located within the processing chamber 102. When the stirring motor 113 is powered on, it rotates, driving the stirring rod 114 to rotate, stirring the sewage and reagents in the processing chamber 102 for a uniform mixture. Multiple auxiliary rods 115 rotate with the stirring rod 114 to expand the stirring range and achieve a better mixing effect.

[0025] Using a deep denitrification sewage treatment device of this embodiment, the sewage first enters the collection box 101 for preliminary sedimentation, and then is pumped into the treatment chamber 102 by a water pump. The medicine box 111 placed above the treatment chamber 102 is filled with a medicine containing Mg2+ and PO43-. The valve of the medicine box 111 is opened to add the medicine. The amount of the medicine is monitored by a gravity sensor. At the same time, the stirring motor 113 is started to drive the stirring rod 114 and the auxiliary rod 115 to rotate to mix them evenly and perform preliminary denitrification. Then, the sewage is pumped into the regulating chamber 103 by a water pump. In the process, sodium hypochlorite solution is sprayed from the nozzle 107 to mix with the sewage. The design of the multiple extension rods 106 and the nozzle 107 expands the contact range of the solution. At the same time, the power motor 116 is started to drive the connecting rod 105 and the extension rod 106 to rotate. While expanding the contact range, the sewage and the solution are stirred and mixed evenly to perform secondary denitrification. Then the sewage is pumped into the sedimentation tank 104 for adsorption, which makes the sewage treatment cleaner. The sodium chlorate solution is evenly distributed in the regulating tank 103 and is fully mixed, ensuring the overall denitrification effect.
