Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, specifically an integrated device for removing low concentrations of total nitrogen from wastewater treatment plant effluent. Background Technology
[0002] Wastewater treatment plant effluent refers to the residual water produced after wastewater treatment, also known as sludge biochemical liquid. The effluent contains a certain amount of suspended solids, organic matter, microorganisms, etc., and needs to be treated during the treatment process to meet the discharge standards or reuse requirements.
[0003] Furthermore, wastewater often contains a large amount of total nitrogen. Therefore, the removal of total nitrogen is also an important indicator of whether wastewater meets discharge standards.
[0004] For the treatment of low concentrations of total nitrogen, existing methods involve adding an appropriate amount of lime to the inside of the wastewater tank to react with the substances contained in the total nitrogen, thereby achieving the purpose of removal. However, during the reaction with lime, precipitates are generated and accumulate at the bottom of the wastewater tank. Most existing treatment methods require workers to enter the tank to remove them, which is slow, time-consuming, and labor-intensive, affecting the efficiency of subsequent wastewater treatment.
[0005] Therefore, it is necessary to propose an integrated device for removing low concentrations of total nitrogen from wastewater treatment plant effluent. Utility Model Content
[0006] To address the shortcomings of existing technologies, this utility model provides an integrated device for removing low-concentration total nitrogen from wastewater treatment plant effluent. It has the advantages of eliminating the need for manual cleaning of the internal tank, facilitating easy cleaning, and improving treatment efficiency, thus solving the problems mentioned in the background technology.
[0007] This utility model provides the following technical solution: an integrated device for removing low-concentration total nitrogen from wastewater treatment plant effluent, comprising a treatment tank:
[0008] The processing chamber is equipped with a sedimentation frame inside, and the outer side of the sedimentation frame is attached to the bottom of the processing chamber.
[0009] Both sides of the processing box are fixedly connected to U-shaped frames. A connecting shaft is rotatably connected inside the U-shaped frame. Connecting columns are fixedly connected to the two sides of the sedimentation frame. V-shaped connecting rods are fixedly connected to adjacent connecting columns. A connecting rope is connected to the end of the V-shaped connecting rod. The other end of the connecting rope is wrapped around the outer surface of the U-shaped frame.
[0010] Preferably, a motor is mounted on the side of the processing box, and the output shaft of the motor is fixedly connected to the end of the U-shaped frame.
[0011] Preferably, fixed pulleys are installed on both sides of the upper surface of the processing box, and the outer surface of the fixed pulleys is in contact with the lower side of the outer surface of the connecting rope.
[0012] Preferably, fixed pulleys are installed on the top of both sides of the processing box, and the outer surface of the fixed pulleys is in contact with the lower side of the outer surface of the connecting rope.
[0013] Preferably, filter grooves are provided on both sides of the sedimentation frame.
[0014] Preferably, a placement box is installed on the left side of the processing box, and a discharge pipe is installed on the right side of the processing box, with a valve installed on the discharge pipe.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] This integrated device for removing low-concentration total nitrogen from wastewater treatment plant effluent operates by uniformly adding lime, placed inside the tank, to the wastewater. Through stirring and sedimentation, the lime reacts with the total nitrogen in the wastewater to form a precipitate, which accumulates inside a sedimentation frame. The treated wastewater is then discharged from the tank. A motor drives a connecting shaft to wind up a connecting rope, which, in conjunction with a V-shaped connecting rod and a connecting column, lifts the sedimentation frame, thus removing the precipitate from the tank. This design effectively treats low-concentration total nitrogen in wastewater, neutralizes the pH of the wastewater with lime, and rapidly processes the precipitate produced during the reaction, allowing for continued wastewater treatment. No manual intervention is required to clean the precipitate from inside the tank, reducing processing steps and improving efficiency. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figure 1 , Figure 2 and Figure 3 An integrated device for removing low concentrations of total nitrogen from wastewater treatment plant effluent includes a treatment tank 1.
[0028] The processing chamber 1 is equipped with a sedimentation frame 110 inside, and the outer side of the sedimentation frame 110 is attached to the bottom of the interior of the processing chamber 1.
[0029] Both sides of the processing box 1 are fixedly connected to U-shaped frames 117. A connecting shaft 119 is rotatably connected inside the U-shaped frame 117. Both sides of the sedimentation frame 110 are fixedly connected to connecting columns 112. V-shaped connecting rods 113 are fixedly connected to adjacent connecting columns 112. A connecting rope 116 is connected to the end of the V-shaped connecting rod 113. The other end of the connecting rope 116 is wrapped around the outer surface of the U-shaped frame 117. A motor 118 is installed on the side of the processing box 1. The output shaft of the motor 118 is fixedly connected to the end of the U-shaped frame 117.
[0030] In use, lime is evenly added to the sewage inside the treatment tank 1, and the sewage and lime are mixed and stirred by an external stirring mechanism to ensure that the lime can fully react with the total nitrogen in the sewage. The precipitate produced by the reaction of lime and total nitrogen settles for a period of time and accumulates inside the sedimentation frame 110. At this time, the treated sewage is discharged. The operation of motor 118 drives the connecting shaft 119 to wind up the connecting rope 116, so that the connecting rope 116, V-shaped connecting rod 113 and connecting column 112 cooperate to lift the sedimentation frame 110, thereby taking out the precipitate inside the treatment tank 1. At this time, the sedimentation frame 110 moves to the top of the treatment tank 1, which makes it convenient for workers to treat the precipitate inside the sedimentation frame 110.
[0031] As a preferred technical solution of this utility model, fixed pulleys 114 are installed on both sides of the upper surface of the processing box 1. The outer surface of the fixed pulleys 114 is in contact with the lower side of the outer surface of the connecting rope 116. Fixed pulleys 115 are installed on the top of both sides of the processing box 1. The outer surface of the fixed pulleys 115 is in contact with the lower side of the outer surface of the connecting rope 116.
[0032] The combined use of fixed pulley 114 and fixed pulley 115 ensures the stability of the connecting rope 116 in lifting the sedimentation frame 110, while avoiding friction between the connecting rope 116 and the processing box 1, thus ensuring the service life of the connecting rope 116.
[0033] As a preferred technical solution of this utility model, filter grooves 111 are provided on both sides of the sedimentation frame 110.
[0034] The filter tank 111 can effectively drain excess water from the sedimentation box 110, reducing the burden on workers in handling sediment.
[0035] As a preferred technical solution of this utility model, a placement box 2 is installed on the left side of the processing box 1, and a discharge pipe 3 is installed on the right side of the processing box 1, with a valve 4 installed on the discharge pipe 3.
[0036] The container 2 is used to hold the required lime material, and the discharge pipe 3 and valve 4 are used to discharge the treated wastewater.
