Description

Technical Field

[0001] This utility model relates to the field of aquaculture wastewater treatment technology, specifically to an aquaculture wastewater treatment device. Background Technology

[0002] Compared to domestic sewage and industrial wastewater, aquaculture wastewater has the following characteristics: 1. Aquaculture wastewater is generally discharged centrally, with high nitrogen pollution load and large volume; 2. The wastewater has a low C / N ratio, making it difficult for traditional biological treatment technologies to effectively remove nitrogen; 3. Aquaculture wastewater contains a high concentration of dissolved oxygen, which competes with nitrate nitrogen for electrons, hindering denitrification. Therefore, an effective nitrogen removal system capable of operating under low C / N and high DO conditions is needed to solve the pollution problem of aquaculture wastewater. Utility Model Content

[0003] The purpose of this invention is to provide a wastewater treatment device for aquaculture, in order to solve the problem mentioned in the background art of effectively denitrifying aquaculture wastewater pollution under low C / N and high DO conditions.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model is a device for treating aquaculture wastewater, comprising:

[0006] A bioelectrochemical tower reactor, wherein the bioelectrochemical tower reactor is equipped with bioelectrochemical packing material.

[0007] A biochemical reactor, wherein baffles are fixedly connected at equal intervals to the inner wall of the biochemical reactor;

[0008] A circulating pump is provided, with its input end threadedly connected to one side of the lower end of the biochemical reactor, and its output end fitted with a reflux pipe. One end of the reflux pipe is threadedly connected to the lower part of one side of the bioelectrochemical tower reactor, and a flow meter is threadedly provided on the side of the reflux pipe closest to the bioelectrochemical tower reactor.

[0009] Furthermore, the upper part of one side of the bioelectrochemical tower reactor is connected to a connecting pipe, and one end of the connecting pipe is connected to the upper part of one side of the biochemical reactor.

[0010] Furthermore, the upper part of the other side of the biochemical reactor is connected to a water outlet pipe, and both one end of the water outlet pipe and the end of the connecting pipe are threaded with solenoid valves.

[0011] Furthermore, there are three partitions, which divide the interior of the biochemical reactor into an inlet zone, an outlet zone, and a wastewater treatment zone, with the wastewater treatment zone being interconnected vertically.

[0012] Furthermore, it also includes a convenient installation structure, which includes a connecting groove, a movable spring, and a positioning post. The connecting groove is symmetrically opened at one end on both sides of the partition, and a movable spring is provided in the connecting groove. A positioning post is provided at one end of the movable spring.

[0013] Furthermore, a first ring block is fixed to one end of the movable spring, and the first ring block is fitted into the connecting groove through a first sleeve fixed in the middle of one side. A second ring block is fixed to the other end of the movable spring, and a sleeve is fixed to one end of the positioning post, and the second ring block is fitted into the sleeve through a second sleeve fixed in the middle of one side.

[0014] This utility model has the following beneficial effects:

[0015] I. This utility model uses manganese ore as a bioelectrochemical packing material, which can efficiently remove nitrate nitrogen from wastewater. The treated wastewater then enters a biochemical reactor to cultivate active biological strains. The strains are then transported to the bioelectrochemical tower reactor using a circulating pump to adhere to the surface of the bioelectrochemical packing material, forming a microbial biofilm. This ensures a high specific surface area of ​​the packing material while improving the ammonia nitrogen removal rate of the bioelectrochemical tower reactor.

[0016] II. Based on the above-mentioned beneficial effects, the baffle used in the biochemical reactor uses a positioning column with elastic connection at one end on both sides for installation and fixation of its own structure. When disassembling, pressure is applied to one side of the baffle to ensure that the positioning column on that side can be disengaged from the connecting groove, so that the other side of the baffle can be easily disassembled. When installing, the reverse steps are applied. Disassembly and assembly are convenient, quick and easy, saving time and effort. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-3 As shown, this utility model is a device for treating aquaculture wastewater, comprising:

[0026] Bioelectrochemical tower reactor 1, with bioelectrochemical packing material 2 inside;

[0027] Bioelectrochemical packing material 2 is made of manganese ore, which can efficiently remove nitrate nitrogen.

[0028] Bioreactor 4, with partitions 5 fixedly connected at equal intervals on the inner wall of bioreactor 4;

[0029] There are three partitions 5, and the partitions 5 divide the interior of the biochemical reactor 4 into an inlet zone, an outlet zone and a wastewater treatment zone. The wastewater treatment zone is connected in a loop.

[0030] The baffle 5 is designed to prevent backflow and allow for multiple flows of wastewater, which in turn allows the wastewater to mix thoroughly with the activated sludge. The inlet and outlet zones are located at the inner ends of the bioreactor 4, while the wastewater treatment zone is located in the center of the bioreactor 4.

[0031] The circulation pump 8 has its input end threadedly connected to one side of the lower end of the biochemical reactor 4, and the output end of the circulation pump 8 is fitted with a return pipe 7. One end of the return pipe 7 is threadedly connected to the lower part of one side of the bioelectrochemical tower reactor 1, and a flow meter 6 is threadedly installed on the side of the return pipe 7 near the bioelectrochemical tower reactor 1.

[0032] The circulating pump 8 transports the active sludge through the return pipe 7 to the bioelectrochemical tower reactor 1, where it attaches to the surface of the bioelectrochemical packing 2 to form a biofilm, thereby increasing the biological reaction area and improving the treatment effect. The flow meter 6 monitors and controls the transport flow rate.

[0033] A connecting pipe 3 is threadedly connected to the upper part of one side of the bioelectrochemical tower reactor 1, and one end of the connecting pipe 3 is threadedly connected to the upper part of one side of the biochemical reactor 4.

[0034] The connecting pipe 3 facilitates the transfer of wastewater treated in the bioelectrochemical tower reactor 1 to the biochemical reactor 4.

[0035] The upper part of the other side of the biochemical reactor 4 is connected to a water outlet pipe 9, and a solenoid valve 10 is threaded on one end of the water outlet pipe 9 and the end of the connecting pipe 3.

[0036] The outlet pipe 9 discharges the treated wastewater, and the solenoid valve 10 is used to open and close the connecting pipe 3 and the outlet pipe 9.

[0037] Working principle: The top cover of the bioelectrochemical tower reactor 1 is opened to allow the conveyor belt to treat wastewater. The wastewater is pre-contaminated with the bioelectrochemical packing material 2, and the pollutants in the wastewater are degraded by the microbial biofilm on the surface of the bioelectrochemical packing material 2. Subsequently, the solenoid valve 10 on the connecting pipe 3 is opened to transport the wastewater to the biochemical reactor 4. To prevent short-circuiting, the biochemical reactor 4 is divided into multiple compartments by the baffle 5, allowing the wastewater to flow multiple times within the reactor. The wastewater is thoroughly mixed with the activated sludge, further degrading the wastewater. Subsequently, the solenoid valve 10 on the outlet pipe 9 is opened for discharge, and the activated sludge is transported to the bioelectrochemical tower reactor 1 through the return pipe 7 by the circulation pump 8, so as to increase the microbial biofilm area by attaching to the bioelectrochemical packing material 2.

[0038] This solution can effectively remove nitrate nitrogen, COD, ammonia nitrogen and phosphorus from wastewater to meet the needs of aquaculture, and does not require the addition of carbon source when the C / N ratio is low, effectively reducing the cost of use.

[0039] Please see Figure 1-3 As shown, this embodiment is based on the above embodiment 1, and also includes a convenient installation structure. The convenient installation structure includes a connecting groove 51, a movable spring 52 and a positioning post 53. The connecting groove 51 is symmetrically opened at one end on both sides of the partition 5, and the movable spring 52 is provided in the connecting groove 51. The positioning post 53 is provided at one end of the movable spring 52.

[0040] One end of the movable spring 52 is fixed with a first ring block 54, and the first ring block 54 is sleeved in the connecting groove 51 through a first sleeve post 56 fixed in the middle of one side. The other end of the movable spring 52 is fixed with a second ring block 55. One end of the positioning post 53 is fixed with a sleeve 58, and the second ring block 55 is sleeved in the sleeve 58 through a second sleeve post 57 fixed in the middle of one side.

[0041] The connecting groove 51 is used in conjunction with the first ring block 54 and the first sleeve 56 to connect the movable spring 52. The second ring block 55 is used in conjunction with the second sleeve 57 and the sleeve 58 to fix the movable spring 52 to the positioning column 53. The structure installation of the partition plate 5 is completed by using the sleeve between the positioning column 53 and the opening in the inner wall of the biochemical reactor 4.

[0042] Working principle: When installing the partition 5, the positioning post 53 on one side of the partition 5 is pre-extended into the corresponding opening on the inner wall of the bioreactor 4, and an inward pressing force is applied to the positioning post 53 on the other side of the partition 5. The positioning post 53 is extended into the connecting groove 51 by the compression of the movable spring 52, and the connecting groove 51 is aligned with another opening on the inner wall of the bioreactor 4. After the force is released, the movable spring 52 returns to its original deformation, causing the positioning post 53 to extend into the opening. The reverse steps are applied when disassembling.

[0043] This solution allows for quick and easy assembly and disassembly of partition 5, saving time and effort.
