Description

Technical Field

[0001] The utility model relates to the field of water supply monitoring, in particular to the technical field of algae growth monitoring simulation experimental devices. Background Art

[0002] In the water supply and water treatment industry, the overgrowth of algae, especially the outbreak of odor-producing algae (such as cyanobacteria), has become a major challenge affecting water quality safety and ecosystem health. Algae not only consume a large amount of dissolved oxygen, causing water hypoxia, but also produce algal toxins that pose a serious threat to human health. Therefore, effectively monitoring and controlling the growth of algae, especially exploring the mechanism of the impact of hydraulic retention time (HRT) on it, has become a key technical requirement for ensuring drinking water safety and maintaining water environment quality.

[0003] Although there are a variety of algae monitoring equipment available to address the problem of algae growth, most of them focus on monitoring the total amount or conventional algae. The development of specific monitoring technology for olfactory algae is still lagging behind, especially in the real-time monitoring and analysis of the growth dynamics of olfactory algae under different HRT conditions.

[0004] Therefore, how to accurately evaluate and regulate HRT to prevent excessive algae growth has become an urgent problem to be solved. Utility Model Content

[0005] In view of the above technical limitations, the utility model aims to design an experimental device specifically for monitoring algae growth, focusing on the direct effect of HRT (hydraulic retention time) on algae growth.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An algae growth monitoring simulation experimental device comprises a light-proof culture barrel, a top cover, a water supply device connected to the lower end of the culture barrel and conveying raw water to the culture barrel, a light source arranged at the upper end of the culture barrel, a sampling port arranged on the side wall of the culture barrel, and an overflow port arranged between the sampling port and the upper edge of the culture barrel;

[0008] The water supply device comprises a light-proof liquid storage tank for storing raw water, and the raw water in the liquid storage tank is transported to the culture barrel in one direction at a fixed flow rate.

[0009] Compared with the prior art, this case utilizes a water supply device connected to the lower end of the culture barrel and an overflow port arranged at the upper end of the culture barrel. The HRT (hydraulic retention time) in the barrel is controlled by different water supply times of the water supply device, thereby realizing real-time monitoring of the growth dynamics of algae under different HRT (hydraulic retention time) conditions.

[0010] In a preferred embodiment, it also includes an input pump for delivering the raw water from the liquid storage tank to the culture barrel at a fixed flow rate, a check valve arranged at one end of the culture barrel, and a water delivery pipe connecting the liquid storage tank and the input pump and the input pump and the culture barrel, wherein the water delivery pipe is a pipe group of different pipe diameters that can be used interchangeably. By replacing input pipes of different pipe diameters, the expansion of real-time dynamic monitoring of HRT (hydraulic retention time) can be further achieved.

[0011] In a preferred embodiment, the input pump is a diaphragm pump, which pumps raw water from the reservoir and adjusts the flow rate of the incoming water so that the living environment of the olfactory algae in the device is completely consistent with that of the reservoir.

[0012] In some embodiments, the water supply device further comprises an aerator for aerating the liquid storage tank to prevent possible accumulation of 2-MIB (2-Methylisoborneol).

[0013] In a preferred embodiment, a plurality of air pipes are provided between the aerator and the liquid storage tank to ensure uniform aeration.

[0014] In a preferred embodiment, the gas delivery pipe is a group of pipes of different diameters that can be used interchangeably.

[0015] In some embodiments, the sampling port includes a first sampling port and a second sampling port spaced apart on the upper and lower side walls of the culture barrel. When sampling, the samples can be taken separately and then mixed and stirred to improve the test uniformity.

[0016] In a preferred embodiment, the first sampling port is arranged at the upper end of the center of the side wall of the culture barrel, and the second sampling port is arranged at the lower end of the center of the side wall of the culture barrel.

[0017] In a preferred embodiment, the distance between the overflow port and the top of the culture barrel and the distance between the second sampling port and the bottom of the culture barrel are the same.

[0018] In some embodiments, the light source is disposed inside the top cover. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following examples further illustrate the features of the present invention and other related features to facilitate understanding by those skilled in the art:

[0022] This invention aims to design an experimental device specifically for monitoring algae growth, focusing on the direct effect of HRT (hydraulic retention time) on algae growth. Figure 1 The present invention provides an algae growth monitoring simulation experimental device, comprising a light-proof culture barrel 100, which is provided with a top cover 110. An external water supply device 200 is connected to the lower end of the culture barrel 100 to deliver raw water to the culture barrel 100. The raw water here refers to filtered reservoir raw water.

[0023] A light source 120 is also provided at the upper end of the culture barrel 100. The light source 120 may be a fluorescent lamp, which is a common choice because it can provide a spectrum close to natural sunlight and is suitable for the growth requirements of most algae. Of course, a combined LED light source may also be used. In a preferred case, the light source 120 may be provided on the top cover 110 for easy disassembly and installation.

[0024] The culture barrel 100 is provided with a sampling port 130, and an overflow port 140 is provided between the upper end of the sampling port 130 and the upper edge, i.e., the top of the culture barrel 100. When the water supply device 200 delivers raw water, the excess water overflows through the overflow port 140, that is, the present case can be monitored in real time.

[0025] Please refer to Figure 2 , explaining the arrangement relationship between the sampling port 130 and the overflow port 140, for the convenience of explanation, Figure 2 The sampling port 130 and the overflow port 140 are arranged on opposite sides, and their directions can be arranged as follows: Figure 1 The same side shown, its protection scope should not be limited by the accompanying drawings. In some embodiments, the sampling port 130 includes a first sampling port 131 respectively arranged at the upper end of the side wall of the culture barrel 100 and a second sampling port 132 arranged at the lower end of the side wall of the culture barrel 100. In this way, through the two sampling ports spaced apart from each other, the samples can be taken separately and then mixed and stirred to improve the uniformity of the test. In the preferred case, the first sampling port 131 is arranged at the upper end of the center of the side wall of the culture barrel 100, and the second sampling port 132 is arranged at the lower end of the center of the side wall of the culture barrel 100, and the distances between them and the center are equal. Figure 2 For the sake of clarity, the center line L1 is used to represent the center as described above.

[0026] As a preferred embodiment, when the height of the center line L1 is assumed to be 2d, the height of the second sampling port 132 is d, the height of the first sampling port 131 is 3d, and the height of the overflow port 140 is 4d, and the height of the entire culture barrel 100 is 5d. That is, at this time, the distance between the overflow port 140 and the top of the culture barrel 100 and the distance between the second sampling port 132 and the bottom of the culture barrel 100 are the same. Through such a uniform opening design, the culture and sampling in the barrel are more uniform.

[0027] Please continue to refer to Figure 1 The water supply device 200 includes a light-proof liquid storage tank 210 that can store the raw water as described above. It also includes an input pump 220, which transports the raw water in the liquid storage tank 210 to the culture barrel 100 at a fixed flow rate. This is also one of the experimental conditions of this case. This condition is a commonly used setting in water treatment experiments and will not be repeated here. For the selection of the input pump 200, a diaphragm pump is preferred. The key feature of the diaphragm pump is that a flexible diaphragm is used to isolate the transported liquid from the pump's piston and pump cylinder, which can protect the important components of the pump from direct erosion by the transported liquid. Therefore, it is more suitable for experimental devices.

[0028] The water supply device 200 also includes a check valve 221 disposed at one end of the culture barrel 100, and a water pipe 230 connecting the liquid storage tank 210 and the input pump 220, and the input pump 220 and the culture barrel 100. Here, the water pipe 230 is a pipe group of different pipe diameters that can be used interchangeably. By replacing the input pipes 230 of different pipe diameters, the expansion of the real-time dynamic monitoring of HRT (hydraulic retention time) can be further achieved.

[0029] In this way, the hydraulic retention time in the barrel is controlled by running the input pump of the water supply device at different times per hour, thereby achieving real-time monitoring of the growth dynamics of algae under different HRT (hydraulic retention time) conditions.

[0030] In practical applications, since the algae growth monitoring experimental device in this case is a continuous monitoring, it is necessary to aerate the liquid storage tank 210 to prevent possible accumulation of 2-MIB (2-Methylisoborneol).

[0031] For its specific implementation, please continue to refer to Figure 1 The water supply device 200 also includes an aerator 240 for aerating the liquid storage tank 210. A plurality of air pipes 241 are provided between the aerator 240 and the liquid storage tank 210, and a vent valve 242 is provided at each connection with the liquid storage tank 210. In a preferred case, the plurality of air pipes 241 can be evenly distributed in the liquid storage tank 210 to improve the uniformity of aeration of the liquid storage tank 210. Specifically, the air pipes 241 are groups of pipes of different diameters that can be used interchangeably, and the adjustment of the aeration amount can be expanded.

[0032] As mentioned above, this case protects an algae growth monitoring simulation experimental device, and all technical solutions that are the same or similar to this case should be deemed to fall within the scope of protection of this case.
