Description

Technical Field

[0001] The utility model relates to the technical field of biological indicator detection, in particular to a biological indicator detection device for new pollutants in wastewater. Background Art

[0002] Bioindicators are a method of detecting environmental pollutants through biological reactions. They are often used to monitor pollutants in wastewater. Bioindicators can be specific microorganisms, aquatic organisms or plants, and they have different sensitivities to specific pollutants in the environment. There are many types of new pollutants that may exist in wastewater, and there may be residues of various industrial chemicals in wastewater, such as solvents, heavy metals, volatile organic compounds, etc. These chemicals come from waste and wastewater discharge during industrial production processes.

[0003] Among them, heavy metal copper in industrial wastewater is the most harmful. When heavy metal copper is detected by biological indicators, the indicator is usually poured directly into the test sample and then placed in a culture dish for culture. It is easily affected by the external environment, which reduces the accuracy of the test results and easily ignores the heavy metal content in the wastewater, which in turn has a negative impact on the surrounding environment. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art that the indicator is directly poured into the test sample and then placed in a culture dish for culture, which is easily affected by the external environment, thereby reducing the accuracy of the test result, and easily ignoring the heavy metal content in the wastewater, thereby having a bad impact on the surrounding environment. A biological indicator detection device for new pollutants in wastewater is proposed to solve the shortcomings of the prior art that the indicator is directly poured into the test sample and then placed in a culture dish for culture, which is easily affected by the external environment, thereby reducing the accuracy of the test result, and easily ignoring the heavy metal content in the wastewater, thereby having a bad impact on the surrounding environment.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A biological indicator detection device for new pollutants in wastewater comprises a box body, a box cover, two inner plates and a partition, wherein the box cover is movably arranged on the top of the box body, and both sides of the box cover are fixedly connected with side plates for facilitating the taking and placing of the box cover, and the partition is fixedly arranged inside the box body, and two inner plates are fixedly arranged inside the same box body, and the two inner plates are respectively located on both sides of the same partition, and placement grooves for placing culture dishes are opened on the two inner plates, and support seats are fixedly connected to the four corners of the bottom of the box body.

[0007] In a possible design, the bottom of the box cover is fixedly connected to a bottom frame, the bottom of the bottom frame is fixedly connected to a sealing ring, the outer top of the box body is fixedly connected to a connecting frame, the top of the connecting frame is provided with a slot matching the bottom frame and the sealing ring, and the bottom frame and the sealing ring both fit into the same slot.

[0008] In a possible design, two circular holes are provided on both sides of the top of the box cover, the inner walls of the two circular holes are fixedly connected with oxygen supply tubes, and the tops of the two oxygen supply tubes are provided with tube covers.

[0009] In a possible design, grooves are provided at the bottoms of the two side panels for facilitating the removal and placement of the box cover.

[0010] In a possible design, a connecting plate is fixedly connected to one side of the box body, connecting blocks are fixedly connected to both sides of one side of the connecting plate, the adjacent sides of the two connecting blocks are rotatably connected to the same rotating column, two bottom blocks are fixedly sleeved on the rotating column, the tops of the two bottom blocks are fixedly connected to the same clamping plate, the tops of the clamping plates are fixedly connected to an elastic band for fixing the clamping plates, and a fixed column is fixedly connected to one side of the box body, and the elastic band is sleeved on the fixed column.

[0011] In a possible design, a plurality of placement plates for placing culture dish placement boxes are fixedly connected to one side of the box body, a blocking bar for blocking the placement boxes is fixedly connected to one side of the top of the plurality of placement plates, and a notch is provided on the front side of the plurality of placement plates for facilitating the taking of the culture dish placement boxes.

[0012] In a possible design, the number of placement slots opened on the top of the two inner plates is set to be multiple.

[0013] In a possible design, a plurality of label frames for marking culture dishes are fixedly connected to the tops of the two inner plates, and the plurality of label frames are respectively located at the front sides of the plurality of placement slots.

[0014] In the present application, when in use, the bottom frame and the sealing ring of the box cover are taken out from the card slot on the connecting frame through the side plate and the groove, and the box cover is removed from the box body, and then the culture dish placement box on the placement plate is opened, and the culture dish is held. Since the baffle and the notch are arranged on the placement plate, the placement box is prevented from falling, and the placement box is convenient to take, thereby improving the practicality and flexibility of the device, and the required wastewater samples and cryptoalgae biological indicators are cultured in the culture dishes, and wastewater samples from different regions and different times are set at the same time, thereby ensuring the comprehensiveness of the test results, saving time and improving the test efficiency, and then placing multiple culture dishes in the placement groove on the inner plate, and adding copper ion solutions of different concentrations and biological indicator culture dishes at the same time.

The box body and box cover are made of glass, which is convenient for observing the sample detection process. After placing the culture dish, the sample record of each culture dish is placed in the label frame of acrylic board material on the inner plate, which is convenient for observing and operating the sample. When the box cover is closed, it is sealed by a sealing ring to reduce the interference of the outside world on the culture dish, and the biological indicator is infused through the oxygen supply tube to ensure its survival, which is convenient for detecting wastewater. After recording it through text, the elastic band on the splint can be removed from the fixed column, and the record text is placed on the connecting plate and clamped by the splint, which is convenient for finding the record text. It can also record all aspects of the sample data in time. During the detection process, when copper algae is exposed to an environment containing high concentrations of copper ions, its growth may be inhibited. This can be judged by observing the growth of copper algae under different copper ion concentrations. If copper algae grows slowly or stops completely under high concentrations of copper ions, it may mean that there is copper pollution, and high concentrations of copper ions may have an adverse effect on the leaves of copper algae. The leaves of copper algae may fade to green or yellow. The change in leaf color can be an indicator that the wastewater contains too high a concentration of copper ions. At the same time, the culture dish can be observed through a microscope. Under the influence of high concentrations of copper ions, copper algae cells may undergo morphological abnormalities or cell wall damage. These changes can be observed through a microscope, further indicating the presence of copper ions. Through testing, heavy metal pollution in wastewater can be detected to ensure the safety of water quality.

[0015] The beneficial effects of the utility model are:

[0016] In the utility model, by sealing the culture dish, the interference of the external environment on the culture dish can be reduced, thereby improving the accuracy of heavy metal detection of wastewater, ensuring the credibility of the detection results, and realizing multiple groups and control groups for culturing. Wastewater samples from different regions and at different times can be set at the same time, thereby ensuring the comprehensiveness of the detection results, saving time, improving detection efficiency, and facilitating the taking and placement of record texts and the culture dishes used, thereby improving the practicality and flexibility of the device.
