Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and in particular relates to a continuous wastewater treatment tank. Background Technology

[0002] Wastewater refers to wastewater generated from industrial production or urban production and daily life. Because wastewater contains a high concentration of pollutants, it can only be recycled and reused after environmental treatment. Environmental treatment of wastewater not only effectively solves the problem of water waste but also effectively avoids water pollution.

[0003] Microbial wastewater treatment is not only highly efficient but also environmentally friendly, making it a crucial step in modern wastewater treatment. Microbial wastewater treatment primarily includes aerobic and anaerobic treatment. Aerobic treatment involves pumping oxygen into the wastewater through aeration to meet the oxygen requirements of aerobic microorganisms for degrading organic and inorganic matter. Anaerobic treatment, on the other hand, requires an oxygen-free environment where anaerobic microorganisms perform environmentally friendly treatment of organic and inorganic matter in the wastewater.

[0004] However, most current wastewater treatment tanks are single-type tanks, meaning that aerobic treatment requires aerobic tanks and anaerobic treatment requires anaerobic tanks. Since anaerobic treatment is mostly a multi-step anaerobic degradation process, the actual wastewater treatment process requires a large number of tanks, resulting in a high cost for the entire wastewater treatment process.

[0005] Furthermore, the large number of tanks leads to an increase in the number of operational steps in the treatment process, which in turn makes the process of microbial degradation of wastewater treatment quite complicated. The entire process requires a high level of professional competence from the operators, and the complex treatment process results in low efficiency in wastewater treatment. Utility Model Content

[0006] Based on the above background, the purpose of this utility model is to provide a continuous sewage treatment tank.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A continuous wastewater treatment tank includes a tank body, which is divided into several independent anaerobic treatment chambers and aeration chambers by several baffles.

[0009] The top of the tank is connected to several negative pressure pipes that are respectively connected to the oxygen-free treatment chamber and the aeration chamber;

[0010] The lower end of the partition is fitted with a material pipeline for conveying materials between the cavities. A valve is installed on the material pipeline, and the valve stem passes through the tank body.

[0011] The aeration chamber is equipped with an aeration mechanism, and the continuous wastewater treatment tank also includes a stirring mechanism, which is used to stir the wastewater in the treatment chamber.

[0012] The mixing mechanism includes a long rotating shaft rotatably connected between the partitions, and a number of blade assemblies located in the processing chamber are fixedly connected inside the long rotating shaft.

[0013] The drive end of the long rotating shaft is located on the outside of the tank, and a drive motor is installed on the drive end of the rotating shaft.

[0014] Preferably, a sewage pump pipe is installed and connected to the left side of the tank, and a drain pipe is connected to the bottom right side of the tank;

[0015] Valves are installed on both the pump sewage pipe and the clean water discharge pipe.

[0016] Preferably, the longitudinal cross-sectional shape of the partition is circular; the partition is welded to the inner wall of the tank cavity.

[0017] Preferably, the aeration mechanism includes an aeration inlet pipe that penetrates the tank body;

[0018] The air outlet end of the inlet aeration pipe is equipped with and connected to several outlet aeration pipes, which are located inside the aeration chamber; several aeration holes are opened on the outlet aeration pipes.

[0019] An aerator is connected to the air inlet end of the aeration pipe.

[0020] Preferably, the aeration pipes are distributed in several layers on the aeration pipe, and each layer has several aeration pipes distributed in a circumferential manner.

[0021] Preferably, a plurality of the baffles divide the tank body into an aeration chamber and a first anaerobic treatment chamber, a second anaerobic treatment chamber, a third anaerobic treatment chamber, and a fourth anaerobic treatment chamber.

[0022] Preferably, the blade assembly includes a plurality of blades symmetrically arranged on the left and right sides.

[0023] Preferably, the blades are arranged at an angle;

[0024] The blades located on the left are tilted to the left, and the blades located on the right are tilted to the right.

[0025] Preferably, the drive motor is fixedly mounted on the tank body via several connecting screws.

[0026] This utility model has the following beneficial effects:

[0027] 1. During operation, the operator controls the opening and closing of the valve by rotating the valve stem. When it is necessary to pump wastewater from the aeration chamber into the adjacent first anoxic treatment chamber, the valve on the negative pressure pipe connected to the top of the first anoxic treatment chamber is opened. After creating a vacuum in the first anoxic treatment chamber, the operator rotates the valve stem at the corresponding position, and the wastewater is pumped into the first anoxic treatment chamber. This process is repeated, allowing wastewater to be sequentially anoxically treated from the aeration chamber through the first to the fourth anoxic treatment chamber, significantly improving the wastewater aeration efficiency.

[0028] The above method enables the integrated aerobic and anaerobic treatment of wastewater within a single tank. This approach not only allows for the treatment of wastewater in stages but also integrates complex treatment steps into a single tank.

[0029] 2. By adopting an integrated treatment approach, not only is the installation cost of wastewater treatment equipment greatly reduced, but the above approach also greatly simplifies the wastewater treatment process from aerobic aeration to anaerobic degradation, thus significantly improving wastewater treatment efficiency.

[0040] Example 1

[0041] like Figure 1 As shown in Figure 5, a continuous wastewater treatment tank includes a tank body 1. The tank body 1 is divided into several independent anaerobic treatment chambers and an aeration chamber A by several partitions. Specifically, four circular partitions 5 (fixed by welding) are arranged sequentially from left to right in the tank body 1, dividing it into an aeration chamber A (aerobic degradation treatment), a first anaerobic treatment chamber B, a second anaerobic treatment chamber C, a third anaerobic treatment chamber D, and a fourth anaerobic treatment chamber E from left to right.

[0042] Meanwhile, the top of tank 1 is connected to several negative pressure pipes 13, which are respectively connected to the anoxic treatment chamber and the aeration chamber A. Valves are installed on the negative pressure pipes 13.

[0043] The lower end of the aforementioned partition 5 is fitted with a material pipe 51 for conveying materials between the cavities. A valve is installed on the material pipe 51, and the valve stem 511 (the valve stem 511 is fixedly connected to a valve plate that controls the opening or closing of the valve) passes through the tank body 1. Specifically, in the existing manner, the valve stem 511 is rotatably connected to the tank body 1, and the rotatable connection position of the tank body 1 is sealed in the existing manner.

[0044] During operation, the operator controls the opening and closing of the valve by rotating valve stem 511. When it is necessary to pump wastewater from aeration chamber A into the adjacent first anoxic treatment chamber B, the valve on the negative pressure pipe connected to the top of the first anoxic treatment chamber B is opened. After creating a vacuum in the first anoxic treatment chamber B, the operator rotates valve stem 511 at the corresponding position, and the wastewater is then pumped into the first anoxic treatment chamber B. This process is repeated, allowing wastewater to be sequentially anoxically treated from aeration chamber A through the first anoxic treatment chamber B up to the fourth anoxic treatment chamber E, thus significantly improving the wastewater aeration treatment efficiency.

[0045] The above method enables the integrated aerobic and anaerobic treatment of wastewater through a single tank 1. This method not only enables the step-by-step treatment of wastewater, but also integrates complex treatment steps into a single tank 1.

[0046] The left side of the aforementioned tank 1 is connected to a sewage pump pipe 11, and the bottom right side of the tank 1 is connected to a drain pipe 12; both the sewage pump pipe 11 and the drain pipe 12 are equipped with valves. During operation, the operator pumps sewage into the tank through the sewage pump pipe 11, and after undergoing the above-mentioned steps, it is discharged from the fourth anoxic treatment chamber E.

[0047] Example 2

[0048] like Figure 1 As shown in Figure 5, based on the structure of Example 1, the aeration chamber A is provided with an aeration mechanism 4, which is used to aeration the wastewater.

[0049] The specific structure of the aeration mechanism 4 is as follows: the aeration mechanism 4 includes an inlet aeration pipe 41 that penetrates the tank 1; the outlet end of the inlet aeration pipe 41 is equipped with and connected to a plurality of outlet aeration pipes 42, the outlet aeration pipes 42 being located in the aeration chamber A; the outlet aeration pipes 42 are provided with a plurality of aeration holes; according to the existing method, the inlet end of the above-mentioned inlet aeration pipe 41 is equipped with and connected to an aerator.

[0050] During operation, the operator turns on the aerator (and simultaneously turns on the corresponding negative pressure pipe) to aerate the sewage. The aeration process agitates the sewage airflow while providing oxygen for the degradation of aerobic microorganisms (the sewage first enters aeration chamber A for aerobic degradation).

[0051] Specifically, the aeration pipes 42 are distributed in several layers on the inlet aeration pipe 41, with each layer having several aeration pipes 42 distributed in a circumferential manner. The wastewater is treated by aeration through the aeration pipes 42 located within the wastewater layer.

[0052] Example 3

[0053] like Figure 1As shown in Figure 5, this embodiment, based on the structure of Embodiment 2, after aeration and aerobic degradation, the wastewater enters a multi-step anaerobic degradation process. Specifically, the anaerobic degradation steps are as follows: the continuous wastewater treatment tank also includes a stirring mechanism 3, which is used to stir the wastewater in the treatment chamber. The stirring mechanism 3 includes a long rotating shaft rotatably connected between partitions 5 (in accordance with conventional methods disclosed in the prior art, bearings rotatably connected to the long rotating shaft are installed on the partitions 5). Several blade assemblies located within the treatment chamber are fixedly connected to the long rotating shaft. The drive end of the long rotating shaft is located outside the tank body 1 (same as in the prior art, a sealed bearing is installed at the penetration point between the tank body 1 and the long rotating shaft). A drive motor 31 is installed at the drive end of the rotating shaft (the drive motor 31 is fixedly installed on the tank body 1 via several connecting screws). In the prior art, the long rotating shaft is rotatably connected to the partitions 5.

[0054] The specific structure of the blade assembly is as follows:

[0055] Each blade assembly includes several blades symmetrically arranged on the left and right sides. The blades are made of stainless steel. Specifically, the blade on the left side (the first blade 33) is inclined to the left, and the blade on the right side (the second blade 32) is inclined to the right.

[0056] The blades are elliptical in shape. During operation, the rotating blade assembly, with its bidirectional tilting design, amplifies the agitation of wastewater. This thorough agitation increases the efficiency of anaerobic degradation treatment.

[0057] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
