[0002] Phosphorus pollution is one of the key factors leading to eutrophication of water bodies. Eutrophication of water bodies can cause massive reproduction of algae, resulting in imbalance of water ecosystem and deterioration of water quality, which not only affects the survival of aquatic organisms, but also brings many hazards to human life and production water. Traditional methods of adding phosphorus removal agents often rely on experience or fixed addition ratios, which are difficult to adapt to the dynamic changes of sewage water quality, water volume and other parameters, resulting in unstable phosphorus removal effects, waste of agents or insufficient addition, etc. With the increasingly stringent environmental protection requirements and the continuous development of sewage treatment technology, a more precise and intelligent method for controlling the addition of phosphorus removal agents is needed.

In order to accurately evaluate the phosphorus removal efficiency of the specific phosphorus removal agent used, firstly, the phosphorus removal agent verification data including the agent reaction efficiency and the agent stock solution concentration data are obtained according to the specific agent, and the agent reaction efficiency and the agent stock solution concentration data are input into the preset phosphorus removal efficiency evaluation model for processing to obtain the phosphorus removal efficiency index;

[0091] Please refer to Figure 5 , Figure 5 The present invention is a flowchart of obtaining a modified dosage of a phosphorus removal agent in a phosphorus removal agent dosage control method based on a multi-parameter mathematical model in some embodiments of the present invention. According to an embodiment of the present invention, the phosphorus removal demand index and the phosphorus removal efficiency index are processed in combination with the phosphorus removal agent efficiency influencing factor to obtain the modified dosage of the phosphorus removal agent, including:

[0092] S51, inputting the phosphorus removal demand index and the phosphorus removal efficiency index into a preset phosphorus removal agent dosage prediction model for processing to obtain a predicted phosphorus removal agent dosage;

[0093] S52. Correct the predicted dosage of the phosphorus removal agent according to the phosphorus removal agent efficiency influencing factor to obtain a corrected dosage of the phosphorus removal agent.

[0094] It should be noted that in order to achieve accurate control of the dosage of the phosphorus removal agent, the obtained phosphorus removal demand index and phosphorus removal efficiency index are input into a preset phosphorus removal agent dosage prediction model for processing to obtain the predicted dosage of the phosphorus removal agent, wherein the phosphorus removal agent dosage prediction model is obtained by obtaining a large number of historical samples of phosphorus removal demand index and phosphorus removal efficiency index and the corresponding phosphorus removal agent predicted dosage training;

[0095] After the water treatment environment changes, in order to more accurately determine the dosage of the phosphorus removal agent, the predicted dosage of the phosphorus removal agent is corrected according to the influencing factor of the phosphorus removal agent efficiency to obtain the corrected dosage of the phosphorus removal agent;

[0096] The calculation formula for the modified dosage of the phosphorus removal agent is:

[0097] ;

[0098] in, To correct the dosage of phosphorus removal agent, , They are the influencing factors of phosphorus removal agent efficiency and the predicted dosage of phosphorus removal agent. It is the preset characteristic coefficient (the characteristic coefficient is obtained by querying the preset phosphorus removal agent addition control platform).

[0099] According to an embodiment of the present invention, the phosphorus removal agent is added according to the corrected dosage of the phosphorus removal agent to perform water treatment, and the real-time phosphorus content of the purified water is obtained, and the real-time phosphorus content of the purified water is processed with the standard phosphorus content data of the purified water to obtain the phosphorus content deviation level state, including:

[0100] Add phosphorus removal agent according to the modified dosage of phosphorus removal agent to treat water, and obtain the real-time phosphorus content of purified water;

[0101] Comparing the real-time phosphorus content of the purified water with the standard phosphorus content data of the purified water to obtain a relative value of the real-time phosphorus content deviation;

[0102] The real-time phosphorus content deviation relative value is compared with a preset phosphorus content deviation threshold, and the phosphorus content deviation level state is obtained according to the range to which the threshold comparison belongs, including a normal deviation level state or an abnormal deviation level state.

[0103] It should be noted that after determining the corrected dosage of the phosphorus removal agent, water treatment is implemented, and then the real-time phosphorus content is obtained at multiple sampling points in the water purification pool. The real-time phosphorus content is pre-processed and averaged to obtain the real-time phosphorus content of the purified water, which is compared with the standard phosphorus content data of the purified water to obtain the relative value of the real-time phosphorus content deviation;

[0104] The real-time phosphorus content deviation relative value calculation formula is:

[0105] ;

[0106] in, is the relative value of real-time phosphorus content deviation, , They are the real-time phosphorus content of purified water and the standard phosphorus content of purified water. The preset characteristic coefficient (the characteristic coefficient is obtained by querying the preset phosphorus removal agent dosing control platform);

[0107] The obtained real-time phosphorus content deviation relative value is compared with the preset phosphorus content deviation threshold to obtain the phosphorus content deviation level state. In this embodiment, the phosphorus content deviation threshold is set to (0, 0.2], (0.2, 1], corresponding to the normal deviation level state and the abnormal deviation level state. For example, the obtained real-time phosphorus content deviation relative value is 0.1, which is the normal deviation level state, and the obtained real-time phosphorus content deviation relative value is 0.3, which is the abnormal deviation level state.

[0108] According to an embodiment of the present invention, the step of adjusting the amount of the phosphorus removal agent to be corrected according to the phosphorus content deviation level includes:

[0109] If the phosphorus content deviation level is in the normal deviation level, the phosphorus removal agent correction dosage is not adjusted;

[0110] If the phosphorus content deviation level state is an abnormal deviation level state, and the real-time phosphorus content of the purified water is less than the standard phosphorus content data of the purified water, the reduction amount of the phosphorus removal agent is obtained by processing according to the relative value of the real-time phosphorus content deviation through a preset phosphorus removal agent reduction method;

[0111] If the phosphorus content deviation level status is an abnormal deviation level status, and the real-time phosphorus content of the purified water is greater than the standard phosphorus content data of the purified water, the increased amount of phosphorus removal agent dosage is obtained through the preset phosphorus removal agent increment method according to the relative value of the real-time phosphorus content deviation and an early warning response is output.

[0112] It should be noted that if the phosphorus content deviation level status is a normal deviation level status, it means that the corrected dosage of the phosphorus removal agent is accurate. If the phosphorus content deviation level status is an abnormal deviation level status, it means that the corrected dosage of the phosphorus removal agent is inaccurate and needs to be optimized and adjusted. At the same time, an abnormal deviation level status will occur if the real-time phosphorus content of the purified water is too high or too low. If the real-time phosphorus content of the purified water is less than the standard phosphorus content data of the purified water, it means that the phosphorus removal agent has been overdosed. The phosphorus removal agent dosage reduction amount is obtained by processing through a preset phosphorus removal agent reduction method according to the relative value of the real-time phosphorus content deviation, wherein the preset phosphorus removal agent dosage reduction method is provided by the phosphorus removal agent dosage control platform; if the real-time phosphorus content of the purified water is greater than the standard phosphorus content data of the purified water, it means that the phosphorus removal agent dosage is insufficient. The phosphorus removal agent dosage increase amount is obtained by processing through a preset phosphorus removal agent increment method according to the relative value of the real-time phosphorus content deviation and an early warning response is output. The preset phosphorus removal agent increment method is provided by the phosphorus removal agent dosage control platform.

[0113] According to an embodiment of the present invention, it also includes:

[0114] Obtain the dephosphorization agent concentration data corresponding to the sampling point position of the preset sampling point of the dephosphorization reaction pool, as well as the distance data between the sampling point position and the agent addition point position; query the preset weight value list according to the distance data to obtain the corresponding weight value;

[0115] Multiplying the phosphorus removal agent concentration data by the weight value to obtain a corresponding phosphorus removal agent concentration verification index;

[0116] The phosphorus removal agent concentration verification index is compared with a preset phosphorus removal agent concentration standard index, and the number of position nodes whose phosphorus removal agent concentration verification index is less than the preset phosphorus removal agent concentration standard index is selected;

[0117] Performing a threshold comparison between the number of position nodes and a preset position node number threshold;

[0118] If it is less than or equal to the preset position node number threshold, no processing will be performed;

[0119] If it is greater than the preset position node number threshold, the circulating water pump is controlled to start the response.

[0120] It should be noted that after the phosphorus removal agent is added to the reaction pool, the dispersion of the agent is affected by many factors, resulting in different agent concentrations at different positions in the reaction pool and different phosphorus removal effects. Therefore, in order to evaluate the overall phosphorus removal effect of the reaction pool, first obtain the phosphorus removal agent concentration data of the preset sampling points in the phosphorus removal reaction pool and the distance data between the sampling point location and the agent addition point location. According to the distance data, query the preset weight value list to obtain the corresponding weight value, where the weight value list is provided by the phosphorus removal agent addition control platform. Multiply the phosphorus removal agent concentration data by the weight value to obtain the corresponding phosphorus removal agent concentration verification index. For example, if the phosphorus removal agent concentration data is 4 mg / L and the weight value is 0.2, then 4*2=0.8 is the phosphorus removal agent concentration verification index. The degree verification index is compared with the preset standard index of phosphorus removal agent concentration. In this embodiment, the standard index of phosphorus removal agent concentration is set to 0.1, and the number of position nodes whose phosphorus removal agent concentration verification index is less than the preset standard index of phosphorus removal agent concentration is further screened, and the number of position nodes is compared with the preset position node number threshold. In this embodiment, the position node number threshold is set to 3. If it is less than or equal to the preset position node number threshold, it means that the dispersion effect of phosphorus removal agent is good, and no processing is performed. If it is greater than the preset position node number threshold, it means that the dispersion effect of phosphorus removal agent is not good, and the circulating water pump is controlled to start the response to improve the dispersion effect of phosphorus removal agent.

[0156] After the water treatment environment changes, in order to more accurately determine the dosage of the phosphorus removal agent, the predicted dosage of the phosphorus removal agent is corrected according to the influencing factor of the phosphorus removal agent efficiency to obtain the corrected dosage of the phosphorus removal agent;

[0158] ;

[0159] in, To correct the dosage of phosphorus removal agent, , They are the influencing factors of phosphorus removal agent efficiency and the predicted dosage of phosphorus removal agent. It is the preset characteristic coefficient (the characteristic coefficient is obtained by querying the preset phosphorus removal agent addition control platform).

[0160] According to an embodiment of the present invention, the phosphorus removal agent is added according to the corrected dosage of the phosphorus removal agent to perform water treatment, and the real-time phosphorus content of the purified water is obtained, and the real-time phosphorus content of the purified water is processed with the standard phosphorus content data of the purified water to obtain the phosphorus content deviation level state, including:

[0161] Add phosphorus removal agent according to the modified dosage of phosphorus removal agent to treat water, and obtain the real-time phosphorus content of purified water;

[0162] Comparing the real-time phosphorus content of the purified water with the standard phosphorus content data of the purified water to obtain a relative value of the real-time phosphorus content deviation;

[0163] The real-time phosphorus content deviation relative value is compared with a preset phosphorus content deviation threshold, and the phosphorus content deviation level state is obtained according to the range to which the threshold comparison belongs, including a normal deviation level state or an abnormal deviation level state.

[0164] It should be noted that after determining the corrected dosage of the phosphorus removal agent, water treatment is implemented, and then the real-time phosphorus content is obtained at multiple sampling points in the water purification pool. The real-time phosphorus content is pre-processed and averaged to obtain the real-time phosphorus content of the purified water, which is compared with the standard phosphorus content data of the purified water to obtain the relative value of the real-time phosphorus content deviation;

[0165] The real-time phosphorus content deviation relative value calculation formula is:

[0166] ;

[0167] in, is the relative value of real-time phosphorus content deviation, , They are the real-time phosphorus content of purified water and the standard phosphorus content of purified water. The preset characteristic coefficient (the characteristic coefficient is obtained by querying the preset phosphorus removal agent dosing control platform);

[0168] The obtained real-time phosphorus content deviation relative value is compared with the preset phosphorus content deviation threshold to obtain the phosphorus content deviation level state. In this embodiment, the phosphorus content deviation threshold is set to (0, 0.2], (0.2, 1], corresponding to the normal deviation level state and the abnormal deviation level state. For example, the obtained real-time phosphorus content deviation relative value is 0.1, which is the normal deviation level state, and the obtained real-time phosphorus content deviation relative value is 0.3, which is the abnormal deviation level state.

[0169] According to an embodiment of the present invention, the step of adjusting the amount of the phosphorus removal agent to be corrected according to the phosphorus content deviation level includes:

[0170] If the phosphorus content deviation level is in the normal deviation level, the phosphorus removal agent correction dosage is not adjusted;

[0171] If the phosphorus content deviation level state is an abnormal deviation level state, and the real-time phosphorus content of the purified water is less than the standard phosphorus content data of the purified water, the reduction amount of the phosphorus removal agent is obtained by processing according to the relative value of the real-time phosphorus content deviation through a preset phosphorus removal agent reduction method;

[0172] If the phosphorus content deviation level status is an abnormal deviation level status, and the real-time phosphorus content of the purified water is greater than the standard phosphorus content data of the purified water, the increased amount of phosphorus removal agent dosage is obtained through the preset phosphorus removal agent increment method according to the relative value of the real-time phosphorus content deviation and an early warning response is output.

[0173] It should be noted that if the phosphorus content deviation level status is a normal deviation level status, it means that the corrected dosage of the phosphorus removal agent is accurate. If the phosphorus content deviation level status is an abnormal deviation level status, it means that the corrected dosage of the phosphorus removal agent is inaccurate and needs to be optimized and adjusted. At the same time, an abnormal deviation level status will occur if the real-time phosphorus content of the purified water is too high or too low. If the real-time phosphorus content of the purified water is less than the standard phosphorus content data of the purified water, it means that the phosphorus removal agent has been overdosed. The phosphorus removal agent dosage reduction amount is obtained by processing through a preset phosphorus removal agent reduction method according to the relative value of the real-time phosphorus content deviation, wherein the preset phosphorus removal agent dosage reduction method is provided by the phosphorus removal agent dosage control platform; if the real-time phosphorus content of the purified water is greater than the standard phosphorus content data of the purified water, it means that the phosphorus removal agent dosage is insufficient. The phosphorus removal agent dosage increase amount is obtained by processing through a preset phosphorus removal agent increment method according to the relative value of the real-time phosphorus content deviation and an early warning response is output. The preset phosphorus removal agent increment method is provided by the phosphorus removal agent dosage control platform.

[0174] According to an embodiment of the present invention, it also includes:

[0175] Obtain the dephosphorization agent concentration data corresponding to the sampling point position of the preset sampling point of the dephosphorization reaction pool, as well as the distance data between the sampling point position and the agent addition point position; query the preset weight value list according to the distance data to obtain the corresponding weight value;

[0176] Multiplying the phosphorus removal agent concentration data by the weight value to obtain a corresponding phosphorus removal agent concentration verification index;

[0177] The phosphorus removal agent concentration verification index is compared with a preset phosphorus removal agent concentration standard index, and the number of position nodes whose phosphorus removal agent concentration verification index is less than the preset phosphorus removal agent concentration standard index is selected;

[0178] Performing a threshold comparison between the number of position nodes and a preset position node number threshold;

[0179] If it is less than or equal to the preset position node number threshold, no processing will be performed;

[0180] If it is greater than the preset position node number threshold, the circulating water pump is controlled to start the response.

[0181] It should be noted that after the phosphorus removal agent is added to the reaction pool, the dispersion of the agent is affected by many factors, resulting in different agent concentrations at different positions in the reaction pool and different phosphorus removal effects. Therefore, in order to evaluate the overall phosphorus removal effect of the reaction pool, first obtain the phosphorus removal agent concentration data of the preset sampling points in the phosphorus removal reaction pool and the distance data between the sampling point location and the agent addition point location. According to the distance data, query the preset weight value list to obtain the corresponding weight value, where the weight value list is provided by the phosphorus removal agent addition control platform. Multiply the phosphorus removal agent concentration data by the weight value to obtain the corresponding phosphorus removal agent concentration verification index. For example, if the phosphorus removal agent concentration data is 4 mg / L and the weight value is 0.2, then 4*2=0.8 is the phosphorus removal agent concentration verification index. The degree verification index is compared with the preset standard index of phosphorus removal agent concentration. In this embodiment, the standard index of phosphorus removal agent concentration is set to 0.1, and the number of position nodes whose phosphorus removal agent concentration verification index is less than the preset standard index of phosphorus removal agent concentration is further screened, and the number of position nodes is compared with the preset position node number threshold. In this embodiment, the position node number threshold is set to 3. If it is less than or equal to the preset position node number threshold, it means that the dispersion effect of phosphorus removal agent is good, and no processing is performed. If it is greater than the preset position node number threshold, it means that the dispersion effect of phosphorus removal agent is not good, and the circulating water pump is controlled to start the response to improve the dispersion effect of phosphorus removal agent. For example, if the number of position nodes obtained is 2, no processing is performed. If the number of position nodes obtained is 4, the circulating water pump is controlled to start the response.
