Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater treatment experimental device based on BFM membrane treatment. Background Technology

[0002] As a technology that combines the advantages of biological treatment and membrane filtration, biofilm technology has shown outstanding performance in the field of wastewater treatment in recent years, especially in terms of improving treatment efficiency, enhancing system stability and reducing land area.

[0003] However, based on the current commissioning and operation of wastewater treatment plants, under conditions of low organic matter concentration influent, there is a risk that the amount of carbon source and coagulant added can easily lead to water quality exceeding the standards, which greatly increases the operating cost and maintenance difficulty of the water plant. Therefore, it is necessary to design a wastewater treatment experimental device based on BFM membrane treatment to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a wastewater treatment experimental device based on BFM membrane treatment to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A wastewater treatment experimental device based on BFM membrane treatment includes:

[0007] A wastewater treatment tank, wherein several mounting frames are provided inside the wastewater treatment tank, and several BFM membrane bodies are fixedly connected inside the mounting frames;

[0008] A fixing bracket is fixedly connected to one side of the mounting frame, and a fixing hole is provided on one side of the fixing bracket;

[0009] A water flow sensor is fixedly connected inside the fixing hole, and a placement groove is provided on the inner wall of the sewage treatment tank;

[0010] A positioning component is disposed on one side of the mounting frame and is used to position the mounting frame.

[0011] Preferably, the positioning component includes:

The pretreated wastewater is then sent to an equalization tank to regulate its quality and quantity, ensuring the stability and effectiveness of subsequent biological treatment. Once inside the wastewater treatment tank, the treated wastewater undergoes bio-enhancing technology using the BFM membrane, where organic matter is degraded by microorganisms into water and carbon dioxide, achieving the desired wastewater treatment effect. A heating wire, when in operation, heats a temperature-conducting frame, transferring the heat to the wastewater in the treatment tank, ensuring the wastewater reaches a suitable temperature for microbial degradation.

[0028] In this embodiment, by setting up a sewage treatment tank 1, when the staff sends the treated sewage into the sewage treatment tank 1, the suspended solids, sediments and some large particulate matter in the sewage can be removed through pretreatment. The pretreated sewage is then sent to an equalization tank to regulate the water quality and quantity of the sewage to ensure the stability and effectiveness of subsequent biological treatment. The treated sewage is then sent into the sewage treatment tank 1, so that after entering the sewage treatment tank 1, the treated sewage can undergo microbial degradation of organic matter in the sewage through the biological efficiency process of the BFM membrane body 3, converting it into water and carbon dioxide, thereby achieving the experimental effect of sewage treatment.

[0029] Specifically, the positioning component includes a card plate 9, which is fixedly connected to one side of the mounting frame 2. Several slots 10 are provided on the inner wall of the sewage treatment tank 1, and the card plate 9 and the slots 10 are movably fitted together.

[0038] In this embodiment, by setting a heating wire 16, when the heating wire 16 is working, the heating wire 16 can heat the temperature conducting frame 8. At this time, the temperature on the temperature conducting frame 8 can be transferred to the sewage in the sewage treatment tank 1, so that the sewage in the sewage treatment tank 1 can reach a suitable temperature for microbial degradation.

[0039] Working steps: 1. By setting up a sewage treatment tank 1, after the treated sewage is sent to the sewage treatment tank 1, the suspended solids, sediments and some large particles in the sewage can be removed through pretreatment. The pretreated sewage is then sent to an equalization tank to regulate the water quality and quantity to ensure the stability and effectiveness of subsequent biological treatment. After the treated sewage is sent to the sewage treatment tank 1, the organic matter in the sewage can be degraded by microorganisms through the biological efficiency process of the BFM membrane body 3, and converted into water and carbon dioxide, thereby achieving the effect of sewage treatment experiment. By setting up a heating wire 16, when the heating wire 16 is working, it can heat the temperature conducting frame 8. At this time, the temperature on the temperature conducting frame 8 can be transferred to the sewage in the sewage treatment tank 1, so that the sewage in the sewage treatment tank 1 can reach a suitable temperature for microbial degradation.

[0040] 2. By setting a water flow sensor 6, the water flow sensor 6 can detect the flow rate of water when passing through the BFM membrane body 3.

By setting a mounting plate 12, after the mounting plate 12 is movably fitted together with the mounting groove 11, the upper end of the mounting frame 2 can be placed inside the sewage treatment tank 1, which facilitates the fixing of the mounting frame 2 inside the sewage treatment tank 1 later. By setting a bolt 14, after the bolt 14 is threadedly connected to the threaded hole 15, the mounting plate 12 can be fixed inside the mounting groove 11.
