[0028] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as being limited to the examples set forth herein; on the contrary, these embodiments are provided so that the present disclosure will be more comprehensive and complete, and the concepts of the example embodiments are fully conveyed to those skilled in the art. The described features, structures, or characteristics may be combined in one or more embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present disclosure. However, those skilled in the art will appreciate that the technical solutions of the present disclosure may be practiced while omitting one or more of the specific details, or other methods, components, devices, steps, etc. may be adopted. In other cases, known technical solutions are not shown or described in detail to avoid obscuring various aspects of the present disclosure.

[0029] In addition, the accompanying drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the figures represent the same or similar parts, and their repeated description will be omitted. Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities can be implemented in software form, or implemented in one or more hardware modules or integrated circuits, or implemented in different networks and / or processor devices and / or microcontroller devices.

[0030] The flowcharts shown in the accompanying drawings are only exemplary and do not necessarily include all the steps. For example, some steps may be decomposed, while some steps may be combined or partially combined, so the actual execution order may change according to the actual situation. In addition, all the terms "first", "second", "third", "fourth", etc. below are only for the purpose of distinction and should not be used as limitations of the present disclosure.

[0031] Figure 1 The block diagram of the water purification effect evaluation system according to an exemplary embodiment of the present disclosure is schematically shown. Figure 1 The water purification effect evaluation system of the embodiment of the present disclosure may include a plant selection system, a first floating bed system, a second floating bed system, a water quality detection system and an analysis device.

[0032] The plant selection system can be used to select a target plant with the highest score from multiple candidate plants according to plant evaluation indicators in multiple dimensions.

[0033] The candidate plants may be optional plants that can be used for the floating bed in the current scene, for example, may include but are not limited to rice, ryegrass, canna, water bamboo, reed, cattail, mushroom grass, water celery, water spinach, iris, water lily and foxtail algae.

[0034] In an exemplary embodiment of the present disclosure, for each candidate plant, a score is given according to plant evaluation indicators of multiple dimensions. The plant evaluation indicators of multiple dimensions may include at least two of vitality indicators, root oxygen secretion function indicators, microbial attachment ability indicators, ornamental indicators, and cost indicators. Among them, the vitality indicator indicates the ability to adapt to the environment; the root oxygen secretion function indicator indicates the ability of the root system to release oxygen into the water body. These indicators can all be pre-configured in the form of text.

[0035] Specifically, the plant evaluation index of each dimension of each candidate plant can be converted into a plant index score, and the statistical value of the plant index score of the candidate plant is determined as the score of the candidate plant, and the plant with the highest score is selected from multiple candidate plants as the target plant.

[0036] Taking canna as an example, first, the text corresponding to the plant evaluation index of each dimension of canna can be obtained, and then the plant index score of each dimension can be determined based on the text. For example, the text can be classified using models such as naive Bayes classifier, decision tree, deep learning, etc. to obtain the corresponding plant index score. Next, the statistical value of the plant index score of each dimension can be used as the score of canna. Specifically, the statistical value can be, for example, any one of an average value, a weighted average value, and a cumulative sum.

[0037] After determining the score of each candidate plant, the plant with the highest score can be selected as the target plant.

[0038] In addition, a plant database may be maintained in advance, which includes text descriptions of various plants and pre-analyzed scores. Therefore, when applying the disclosed solution, the score of each candidate plant can be directly determined from the plant database based on the currently available candidate plants, and the disclosure does not limit this.

[0039] After the target plants are determined, the target plants can be used to build the first floating bed system and the second floating bed system of the present disclosure, thereby respectively performing multiple stages of water purification processes.

[0040] refer to Figure 2 The first floating bed system may include a first water tank container and a first peristaltic pump. The first water tank container includes a floating plate fixed with a first target plant. The first water tank container is equipped with a water inlet and a water outlet, and the first peristaltic pump is used to transport water from a water source to the water inlet of the first water tank container.

[0041] For example, a white plastic water tank can be used as the first water tank container. The volume obtained by multiplying the length, width and height is 42cm×27cm×22cm, which can hold about 25L of water. The main body of the floating bed can be an artificial floating board, which is light in weight, stable in nature and has large buoyancy. Cut a 15cm×15cm foam board, open a circular hole with a diameter of about 4cm in the middle of the foam board, plant the first target plant in the circular hole, and fill the gap between the trunk of the first target plant and the circular hole with a sponge to achieve the effect of fixing the first target plant. The foam board connects the first target plant to the hole of the floating board, and the root system of the first target plant is submerged below the water surface.

[0042] Similarly, the second floating bed system may include a second water tank container and a second peristaltic pump. The second water tank container includes a floating plate fixed with a second target plant. The second water tank container is equipped with a water inlet and a water outlet, and the second peristaltic pump is used to transport water from the water source to the water inlet of the second water tank container.

[0043] The difference from the first floating bed system is that the second target plant in the second water tank container is planted in ceramsite, and the ceramsite is carried by a mesh basket.

[0044] It should be noted that the first target plant and the second target plant are both target plants determined by the plant selection system, and are of the same plant type, for example, both are cannas. The descriptions of "first" and "second" only indicate that they are configured in different floating bed systems.

[0045] In addition, the first floating bed system and the second floating bed system may share the same aeration device.

[0046] The first floating bed system and the second floating bed system can both be used to perform a multi-stage water purification process, which can include a first water purification process, a second water purification process, a third water purification process, and a fourth water purification process.

[0047] In the first water purification process, the first peristaltic pump starts to flow water into the first water tank container, and the second peristaltic pump starts to flow water into the second water tank container. The duration of the first water purification process is, for example, more than 40 days.

[0048] After the first water purification process is completed and before the second water purification process, the expanded clay in the second floating bed system is treated to form a biofilm. During the biofilm forming period, water is continuously passed through the first floating bed system and the second floating bed system. After the biofilm forming is completed, the mesh basket and the target plant are placed in the second floating bed system. During the second water purification process, water is continuously passed through the first water tank container and the second water tank container. The duration of the second water purification process is, for example, more than 40 days. Among them, the biofilm forming of the expanded clay includes inoculating microorganisms on the surface of the expanded clay. The present disclosure does not limit the biofilm forming process. After the biofilm forming, a thin film covered with, for example, a yellow viscous substance can be seen on the surface of the expanded clay.

[0049] In the third water purification process, intermittent aeration is performed in the first water tank container and the second water tank container using an aeration device to increase the amount of dissolved oxygen in the container. The aeration head can be located 8 cm to 10 cm below the water surface, and the aeration time can be from 8 am to 8 pm every day. The duration of the third water purification process is, for example, more than 40 days.

[0050] In the fourth water purification process, the above-water parts of the first target plant and the second target plant are harvested to simulate the actual winter plant harvesting process of the floating bed. For example, the main body of the target plant of Canna lily appears to be withered in the system of the embodiment of the present disclosure, and new buds still emerge at the bottom, so only the above-water part of the target plant is harvested. The time for harvesting and continuing the water purification state is, for example, more than 40 days.

[0051] For the ceramsite applied to the solution of the present disclosure, the embodiment of the present disclosure also provides a solution for preparing the ceramsite.

[0052] refer to Figure 3 First, the water supply sludge can be kneaded into wet sludge balls with a particle size of 0.8 cm to 1.2 cm. Next, the wet sludge balls can be dried, such as air-dried, to obtain dry sludge balls. Subsequently, the dry sludge balls can be preheated at 350°C to 450°C for 10 minutes to 15 minutes, and the preheated dry sludge balls can be roasted at 600°C to 650°C for 5 minutes to 8 minutes, and then cooled to room temperature to obtain ceramsite.

[0053] In addition, in order to ensure the requirements of water inlet, the water purification effect comparison and evaluation system can also include a water inlet control device. The water inlet control device is used to adjust the chemical oxygen demand of the water flowing into the floating bed system to 55mg / L to 65mg / L, the ammonia nitrogen to 10mg / L to 15mg / L, the total phosphorus to 1mg / L to 3mg / L, and the total nitrogen to 15mg / L to 40mg / L. Specifically, the water inlet can be configured once a day.

[0054] The water quality detection system can be used to detect the physical and chemical indicators of the effluent from each stage of the water purification process of the first floating bed system and the second floating bed system. Among them, the physical indicators may include water temperature, dissolved oxygen content, pH, etc. Chemical indicators may include chemical oxygen demand, ammonia nitrogen, total nitrogen and total phosphorus, etc. Specifically, the detection can be carried out in the manner of Table 1:

[0055] Table 1

[0056]

[0057] The analysis equipment can be used to analyze the index data detected by the water quality detection system to determine the comparative evaluation results of the water purification effects of the first floating bed system and the second floating bed system.

[0058] Specifically, the comparative evaluation results of the water purification effects of the first floating bed system and the second floating bed system may include the score of the first floating bed system and the score of the second floating bed system. In addition, it may also include a comprehensive evaluation of the first floating bed system and a comprehensive evaluation of the second floating bed system, wherein the comprehensive evaluation is text information automatically generated by a computer, and may be automatically obtained based on the indicator detection results of the water quality detection system and with the aid of the analysis and processing of the computer's machine learning model, and the present disclosure does not limit this.

[0059] On the one hand, the analysis device can analyze the index data detected by the water quality detection system, respectively determine the physical index score and chemical index score of the water purification effect of the first floating bed system, and perform weighted processing on the physical index score and chemical index score of the water purification effect of the first floating bed system to obtain the score of the first floating bed system. Among them, the weight of the physical index score and the weight of the chemical index score can be the same or different, and the present disclosure does not limit their specific values.

[0060] For physical indicators, the analysis equipment can conduct statistical analysis of the water temperature, dissolved oxygen content and pH of the first floating bed system detected by the water quality detection system in different water purification process stages, that is, conduct analysis of the first water purification process, the second water purification process, the third water purification process and the fourth water purification process respectively.

[0061] Next, the results of the statistical analysis are compared with the threshold range corresponding to each indicator, and the physical indicator score of the water purification effect of the first floating bed system is determined according to the comparison results. Among them, the result of the statistical analysis can be the average or median value of the data detected in each water purification process, and the value is compared with the corresponding threshold range. It should be noted that the value within the threshold range has a higher physical indicator score than that outside the threshold range. The greater the deviation from the threshold range, the lower the physical indicator score, and the present disclosure does not limit the specific numerical value. It is understandable that the final physical indicator score is then determined by combining the comparison results of each indicator, for example, by averaging or weighted averaging, and the present disclosure does not limit this.

[0062] With respect to chemical indicators, the analysis equipment can compare the chemical indicators of the first floating bed system detected by the water quality detection system with the chemical indicators of the influent water to determine the removal rate of each pollutant in the water purification process of each stage of the first floating bed system, and determine the chemical indicator score of the water purification effect of the first floating bed system according to the removal rate of each pollutant in the water purification process of each stage of the first floating bed system. The pollutants correspond to chemical indicators such as the above-mentioned chemical oxygen demand, ammonia nitrogen, total nitrogen and total phosphorus.

[0063] Specifically, the chemical index score of the water purification effect of the first floating bed system can be determined by using the statistical value of the removal rate of each pollutant, and the statistical value is, for example, any one of an average value, a median value, and a weighted average value. In addition, a mapping relationship between the statistical value and the chemical index score can be constructed. After the statistical value is determined, the chemical index score can be determined according to the mapping relationship.

[0064] On the other hand, the analysis equipment can analyze the index data detected by the water quality detection system, respectively determine the physical index score and chemical index score of the water purification effect of the second floating bed system, and weightedly process the physical index score and chemical index score of the water purification effect of the second floating bed system to obtain the score of the second floating bed system.

[0065] For physical indicators, the analysis equipment can conduct statistical analysis of the water temperature, dissolved oxygen content and pH of the second floating bed system detected by the water quality detection system in different water purification process stages, that is, conduct analysis of the first water purification process, the second water purification process, the third water purification process and the fourth water purification process respectively.

[0066] Next, the results of the statistical analysis are compared with the threshold range corresponding to each indicator, and the physical indicator score of the water purification effect of the second floating bed system is determined according to the comparison results. Among them, the result of the statistical analysis can be the average value or median value of the data detected in each water purification process, and the value is compared with the corresponding threshold range. It should be noted that the value within the threshold range has a higher physical indicator score than that outside the threshold range. The greater the deviation from the threshold range, the lower the physical indicator score, and the present disclosure does not limit the specific numerical value. It is understandable that the final physical indicator score is then determined by combining the comparison results of each indicator, for example, by averaging or weighted averaging, and the present disclosure does not limit this.

[0067] With respect to chemical indicators, the analysis equipment can compare the chemical indicators of the second floating bed system detected by the water quality detection system with the chemical indicators of the influent water to determine the removal rate of each pollutant in the water purification process of each stage of the second floating bed system, and determine the chemical indicator score of the water purification effect of the second floating bed system according to the removal rate of each pollutant in the water purification process of each stage of the second floating bed system. The pollutants correspond to chemical indicators such as the above-mentioned chemical oxygen demand, ammonia nitrogen, total nitrogen and total phosphorus.

[0068] Specifically, the chemical index score of the water purification effect of the second floating bed system can be determined by using the statistical value of the removal rate of each pollutant, and the statistical value is, for example, any one of an average value, a median value, and a weighted average value. In addition, a mapping relationship between the statistical value and the chemical index score can be constructed. After the statistical value is determined, the chemical index score can be determined according to the mapping relationship.

[0069] According to some embodiments of the present disclosure, the analysis device is also used to draw a corresponding image based on the removal rate of each pollutant in the water purification process of each stage of the first floating bed system and / or the second floating bed system, and display the image. It should be noted that the image is automatically generated by the analysis device without human intervention.

[0070] like Figure 4 As shown, a schematic diagram of the removal rate of each pollutant in each stage of the water purification process using the first floating bed system as an example is shown. Figure 5 FIG. 1 is a schematic diagram showing the removal rate of each pollutant in each stage of the water purification process using the second floating bed system as an example. It should be noted that Figure 4 and Figure 5 It is only an exemplary description, and its style and specific data are not intended to limit the present disclosure.

[0071] For the embodiment of the ceramsite floating bed system disclosed in the present invention, Figure 6 The figure shows the morphology comparison before and after the water purification process using the ceramsite of the embodiment of the present disclosure. Figure 6 The ceramsite used in the disclosed solution still maintains its original state after being soaked for hundreds of days, and does not dissolve, disintegrate or be lost with water. This shows that the ceramsite prepared by the above-mentioned ceramsite preparation scheme of the present disclosure has high strength and strong resistance to water erosion. The ceramsite is of good quality and suitable for wide promotion.
