[0089] 7. Waste liquid treatment system

[0090] As a preferred solution of this embodiment, this embodiment also includes a waste liquid treatment system, which is connected to the outlet of the outlet pipe 120 and is used to treat the drainage of the outlet pipe 120. Specifically, the waste liquid treatment system includes a waste liquid recovery unit 810 and a waste liquid discharge pipeline 820; the waste liquid recovery unit 810 further includes a disposable subunit 811 and a non-disposable subunit 812, the outlet of the outlet pipe 120 is connected to the disposable subunit 811 and the non-disposable subunit 812 through a pipeline, and the test water body is controlled to flow into the disposable subunit 811 or the non-disposable subunit 812 through a valve; the outlet of the disposable subunit 811 is connected to the waste liquid discharge pipeline 820; a filtering component and a separation component are provided in the disposable subunit 811 to filter and separate the test water body.

[0091] After the simulation test is completed, the test water is selected to flow into the disposable subunit 811 or the non-disposable subunit 812 according to the type of pollutants in the test water. For example, after the simulation test of algae, heavy metals and biological toxicity is completed, the test water is discharged into the disposable subunit 811 for filtration and separation treatment, and the treated test water flows into the waste liquid discharge pipeline 820 for discharge. For other test water bodies that cannot meet the discharge requirements after filtration and separation treatment, they are stored in the non-disposable subunit 812 and then uniformly handed over to a third party for disposal.

[0092] The following will provide a simulation method using the above-mentioned river and lake test water body integrated simulation device.

[0093] (1) Using the test water body switching system 200 to switch the type of simulated water body: when the type of simulated water body is a river type water body, the lifting platform body 210 is controlled to rise; when the type of simulated water body is a lake type water body, the lifting platform body 210 is controlled to lower;

[0094] (2) The remote terminal 600 sends the initial simulation working condition requirements and the test water volume to the water condition control system 300, and the temperature control unit 310, the water level control unit 320, and the flow rate control unit 330 respectively control the temperature, water level, and flow rate of the test water to meet the initial simulation working condition requirements;

[0095] (3) Based on the volume of the test water body and the water quality requirements of the initial simulation conditions, the water quality control system 340 calculates the amount of the pollutant aqueous solution to be added, and adds a corresponding amount of the pollutant aqueous solution to the test water body, while turning on the flow rate control unit 330 to accelerate the mixing of the pollutants and the test water body until the water quality required by the initial simulation conditions is achieved;

[0096] When it is necessary to simulate the pollution situation in a specific area, the mobile platform 720 is controlled to move to the specific area, and the water quality control system 340 releases the corresponding pollutant aqueous solution into the test water body in the specific area;

[0097] (4) When the test water body reaches the initial simulation working condition requirements, the water quality monitoring system 400 monitors the water quality parameters of the test water body and uploads them to the remote terminal 600. The monitored water quality parameters are the water quality parameters required to be monitored in the simulation test; at the same time, the temperature control unit 310, the water level control unit 320 and the flow rate control unit 330 also monitor the temperature, water level and flow rate parameters of the test water body in real time and upload them to the remote terminal 600;

[0098] After steps (1) to (4) are completed, the test water required for the test is obtained and the test water is tested. The test can be:

[0099] ① To verify the effect of specific treatment means on reducing pollutant concentrations. Here, specific treatment means refers to the treatment means used to reduce pollutant concentrations. During and after the test, the water temperature, water level, flow rate and water quality parameter data of the test water body are collected in real time as the basic data for analyzing the test effect of the specific treatment means;

[0100] ② Experiments to study the migration and transformation laws of pollutants in test water bodies; during and after the experiment, real-time data on water temperature, water level, flow rate and water quality parameters of the test water body are collected as the data basis for the subsequent migration and transformation laws of pollutants.

[0101] The test process of the test water body also includes:

[0102] (5) The remote terminal 600 calculates the volume of the test water body according to the uploaded water level parameters, and then calculates the water environment capacity and the target pollutant load reduction of the test water body according to the uploaded water quality parameters and flow rate, and in combination with the target pollutant control concentration given in the test; wherein the water environment capacity is calculated based on the volume and flow rate of the test water body, and the target pollutant load reduction is obtained by subtracting the water environment capacity from the target pollutant concentration, and the target pollutant concentration is obtained from the uploaded water quality parameters.

[0103] (6) The remote terminal 600 adjusts the temperature, water level and flow rate of the test water body according to the test requirements. Specifically, the target values ​​of the temperature, water level and flow rate are sent to the temperature controller 313, the water level controller 323 and the flow rate controller 333. The temperature controller 313, the water level controller 323 and the flow rate controller 333 respectively control the heating rod 311, the water pump 321 and the rotating power unit 331 to adjust the temperature, water level and flow rate of the test water body to reach the target values.

[0104] (7) The image acquisition system 500 acquires images and / or video data of the simulation test process in real time and uploads them to the remote terminal 600. The remote terminal 600 analyzes the relationship between the spectral characteristics of the water body and the concentration of water quality parameters through the image and / or video data, and establishes an inversion algorithm to achieve quantitative monitoring of water quality parameters such as total nitrogen, total phosphorus, chlorophyll, transparency, suspended solids, and turbidity.
