Description

Technical Field

[0001] This utility model relates to the field of industrial wastewater denitrification treatment technology, and in particular to an industrial wastewater denitrification treatment device. Background Technology

[0002] Industrial wastewater denitrification is the process of removing nitrogen from wastewater to prevent eutrophication. It is of great significance for preventing eutrophication, protecting human health, meeting environmental regulations, realizing resource recycling and reuse, and enhancing the environmental image of enterprises.

[0003] Chinese Patent Publication No. CN218320851U discloses a denitrification treatment device for high ammonia nitrogen industrial wastewater, relating to the technical field of industrial wastewater treatment equipment. The device includes a storage tank and a recovery tank. The top of the storage tank is connected to an outlet pipe. A perforation communicating with the interior of the outlet pipe is provided on the outlet pipe. An installation plate is slidably disposed within the perforation. A reagent package is disposed on the installation plate. The installation plate has several through holes. A limiting member is provided on the installation plate to limit the position of the installation plate on the outlet pipe. A sealing plate is fixedly disposed on the installation plate to close the perforation. The aforementioned application has the effect of protecting the health of workers.

[0004] In the aforementioned device, industrial wastewater in the storage tank flows into the recovery tank through the outlet pipe. During this process, the industrial wastewater flows through the reagent package in the outlet pipe. However, the outlet pipe is vertical. As the industrial wastewater flows from the storage pipe into the recovery tank through the outlet pipe, it comes into contact with the reagent and then flows directly into the recovery tank. The industrial wastewater that has come into contact with the reagent will not come into contact with the reagent again. Because the industrial wastewater is in a continuous flow state during this process, the contact time between the industrial wastewater and the reagent in the outlet pipe is limited. This results in a short reaction time between the nitrogen oxides in the industrial wastewater and the reagent package, leading to insufficient and ineffective decomposition and removal of the nitrogen oxides in the industrial wastewater. Utility Model Content

[0005] The main purpose of this invention is to provide an industrial wastewater denitrification treatment device that can effectively solve the problem that the limited contact time between industrial wastewater and the denitrification treatment reagent pack leads to the incomplete decomposition and removal of nitrogen compounds in the industrial wastewater.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1 and Figure 2 As shown, an industrial wastewater denitrification treatment device includes an installation platform 2. Support legs 1 are fixedly connected to the lower left side and the front and rear sides of the horizontal part of the installation platform 2. A treatment tank 4 is fixedly connected to the upper left side of the horizontal part of the installation platform 2. A through water inlet pipe 3 is fixedly connected to the upper left side of the outer surface of the treatment tank 4. A flow obstruction component 5 is provided in the inner cavity of the treatment tank 4. A stirring component 6 is provided in the middle of the inner cavity of the treatment tank 4. A spreading component 7 is provided in the upper part of the inner cavity of the treatment tank 4. A secondary treatment component 8 is provided in the upper right side of the horizontal part of the installation platform 2.

[0025] In the specific implementation, industrial wastewater flows into the treatment tank 4 through the inlet pipe 3. The stirring component 6 is turned on, and the operation of the stirring component 6 drives the spreading component 7 to operate. The agent used to denitrify the industrial wastewater is put into the spreading component 7, and the operation of the spreading component 7 spreads the agent in the treatment tank 4 to contact the industrial wastewater flowing into the treatment tank 4.

[0026] The flow-blocking component 5 blocks the flow of industrial wastewater into and out of the treatment tank 4, slowing down the flow of industrial wastewater and prolonging the reaction time between industrial wastewater and reagents.

[0027] The denitrified industrial wastewater flowing out of the treatment tank 4 will flow into the secondary treatment component 8, where the secondary treatment component 8 will further filter the nitrogen compounds in the industrial wastewater. The industrial wastewater filtered by the secondary treatment component 8 will then flow out of the secondary treatment component 8.

[0028] Specifically, in order to prolong the reaction time between the industrial wastewater and the reagent pack that helps complete the denitrification treatment while the wastewater is flowing, thereby improving the denitrification effect of the industrial wastewater, please refer to... Figure 3 The flow obstruction component 5 includes several baffles 51, which are fixedly connected to the left side of the inner surface of the processing tank 4, and several baffles 52 are fixedly connected to the right side of the inner surface of the processing tank 4; the baffles 51 and the baffles 52 are all arranged in a linear array.

[0029] Further reading Figure 4 The stirring assembly 6 includes a motor 61, which is fixedly connected to the lower left of the horizontal part of the mounting platform 2. The output end of the motor 61 is fixedly connected to a rotating rod 62 via a coupling. The upper end of the rotating rod 62 passes through the lower left of the horizontal part of the mounting platform 2, the lower middle of the processing tank 4, the lower ends of several baffles 51 and several baffles 52, and extends into the processing tank 4. Several stirring rods 63 are fixedly connected to the outer surface of the rotating rod 62. The spreading assembly 7 includes a feed pipe 71, which passes through the upper middle of the processing tank 4 and extends into the processing tank 4. A cylinder 72 is rotatably connected to the cylinder 72. The feed pipe 71 is fixedly connected to the upper end of the cylinder 72. The cylinder 72 is fixedly connected to the upper end of the rotating rod 62. Several spreading pipes 73 are fixedly connected to the lower side of the outer surface of the cylinder 72.

[0030] In practice, industrial wastewater flows into treatment tank 4 through inlet pipe 3. The industrial wastewater flows from top to bottom in treatment tank 4. During this process, several baffles 51 and several baffles 52 will block the flow of industrial wastewater, slowing down the flow process and increasing the reaction time between industrial wastewater and the reagent used for denitrification treatment of industrial wastewater. This allows the reagent to more fully decompose the nitrogen oxides in the industrial wastewater.

[0031] When motor 61 is turned on, it drives the rotating rod 62 to rotate, which in turn drives several stirring rods 63 and the cylinder 72 to rotate. The agent is put into the cylinder 72 through the feed pipe 71. The rotation of the cylinder 72 drives several spreading pipes 73 to rotate. During the rotation, the agent in the cylinder 72 will be discharged through the spreading pipes 73 and spread into the treatment tank 4, so that the agent comes into contact with the industrial wastewater and reacts. At the same time, the spreading pipes 73 spread the agent while rotating, which can make the spreading range of the agent larger, thereby increasing the contact area between the agent and the industrial wastewater.

[0032] Several stirring rods 63 rotate to stir the industrial wastewater and the reagent, so that the reagent can be better mixed in the industrial wastewater, thereby improving the efficiency of the reagent in denitrification treatment of industrial wastewater.

[0033] Specifically, in order to perform secondary treatment of nitrogen oxides in industrial wastewater and thus improve the denitrification effect, please refer to... Figure 5 The secondary treatment component 8 includes a rectangular box 81, which is fixedly connected to the upper right side of the horizontal part of the mounting platform 2. Filter layers 82 are fixedly connected to the middle and lower parts of the inner surface of the rectangular box 81. A liquid separation component 83 is provided on the upper side of the inner surface of the rectangular box 81. A through-flow water outlet pipe 84 is fixedly connected to the lower right side of the rectangular box 81. The liquid separation component 83 includes a water box 832, which is fixedly connected to the upper side of the inner surface of the rectangular box 81. Several round holes 831 are opened in the middle of the lower end of the water box 832. A through-flow curved pipe 833 is fixedly connected to the lower right side of the outer surface of the treatment tank 4. The right side of the curved pipe 833 passes through the middle of the upper end of the rectangular box 81 and the middle of the upper end of the water box 832 and extends into the water box 832.

[0034] Both of the above-mentioned filter layers 82 are composed of a support layer, a filter media layer, and a backwashing sludge removal system. The filter media layer is the main part of filtration and biological denitrification. It is usually composed of granular filter media such as quartz sand and ceramsite. A large number of denitrifying bacteria are attached to the surface of these filter media. Through the dual action of physical filtration and biological denitrification, it can effectively remove nitrogen oxides from industrial wastewater. It is a mature technology in the existing technology. The structure and working principle of this solution will not be elaborated further here.

[0035] In practice, the denitrified industrial wastewater flows from the treatment tank 4 into the curved pipe 833, and then flows out from the water box 832 through several round holes 831, and is evenly distributed on the filter layer 82. This prevents the industrial wastewater from concentrating in a certain area of ​​the filter layer 82, which would cause local overload of the filter material and thus improve the overall filtration effect of the filter layer 82.

[0036] As industrial wastewater flows out of the water box 832 and then out through the outlet pipe 84, it passes through two filter layers 82. The two filter layers 82 perform secondary filtration of nitrogen oxides in the industrial wastewater, thereby further improving the denitrification treatment of industrial wastewater without the need for additional treatment of nitrogen oxides in industrial wastewater, thus improving the efficiency of industrial wastewater denitrification treatment.

[0037] It should be noted that the specific installation method, circuit connection method, and control method of the motor-61 used in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0038] The working principle of this utility model is as follows:

[0039] Industrial wastewater flows into treatment tank 4 through inlet pipe 3. Several baffles 51 and several baffles 52 will block the flow of industrial wastewater.

[0040] When the motor 61 is turned on, it drives the rotating rod 62 to rotate, which in turn drives several stirring rods 63 and the cylinder 72 to rotate. The agent is put into the cylinder 72 through the feed pipe 71. The rotation of the cylinder 72 drives several spreading pipes 73 to rotate. During the rotation, the agent in the cylinder 72 will be discharged through the spreading pipes 73 and spread into the treatment tank 4, where it will react with the industrial wastewater.

[0041] Several stirring rods 63 rotate to stir the industrial wastewater and the reagents, so that the reagents can be better mixed in the industrial wastewater;

[0042] The denitrified industrial wastewater flows from the treatment tank 4 into the curved pipe 833, and then flows out through several round holes 831 from the water box 832. The wastewater then passes through two filter layers 82, which perform secondary filtration of nitrogen oxides in the wastewater. Finally, the wastewater flows out through the outlet pipe 84 from the rectangular box 81. The above describes the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made without departing from the spirit and scope of this utility model, and all such changes and modifications fall within the scope of the claims.
