Water treatment method for online control of swimming pool

Abstract

The invention discloses a water treatment method for online control of a swimming pool. The water treatment method comprises the following steps: step 1, adding an agent at one time according to a theoretical agent adding amount and an empirical correction value; 2, setting a delayed observation stage after dosing, and stopping dosing during the period; and step 3, after the time delay is finished, determining whether to continue dosing according to the signal state. After an ON signal is sent out by a starting command, the dosing system stops dosing according to the theoretical amount of turbidity urea and an experience correction value, if the starting command is OFF after 12 or 8 hours, the dosing system waits for a next ON signal, and if the command is continuously ON, the dosing amount is started again; meanwhile, the dosage of the medicament (such as a flocculating agent or urease) is optimized, excessive dosage is avoided, and the water treatment efficiency and the resource utilization rate are improved.

Description

Technical Field

[0001] The invention relates to the technical field of swimming pool water treatment, in particular to a swimming pool online controlled water treatment method. Background Art

[0002] In the modern swimming pool water treatment process, real-time monitoring and control of water quality parameters is the core link to ensure the safety of swimmers and the stability of swimming pool water quality. However, for parameters with long reaction time such as turbidity and urea, the traditional on-off or PID control method has the following defects:

[0003] (1) Turbidity treatment issues

[0004] Turbidity reduction is closely related to the cycle of pool water passing through the filter, and usually takes more than 12-36 hours to show the effect. However, the traditional on-off or PID control mode will continuously send out dosing signals, resulting in excessive dosing of flocculants, increasing the waste of chemicals and operating costs.

[0005] (2) Urea treatment issues

[0006] In a swimming pool, the reaction time of urease to degrade urea takes at least 8-24 hours. If the urea over-limit signal persists, the on-off or PID system will repeatedly add urease, resulting in excessive dosage and possibly causing other water quality problems.

[0007] The above problems not only increase the cost of the reagents, but may also cause water quality instability or damage to the equipment. Therefore, an optimized intelligent control method is needed, which can dynamically adjust the dosage and frequency of the reagents according to the response time of turbidity or urea. Therefore, in view of this, the existing structure is studied and improved to provide a swimming pool online control water treatment method, in order to achieve a more practical purpose. Summary of the invention

[0008] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0009] The present invention provides a water treatment method for online control of a swimming pool, comprising the following steps:

[0010] Step 1: Add the agent at one time according to the theoretical dosage plus the empirical correction value;

[0011] Step 2: After drug administration, a delayed observation phase is set, during which drug administration is stopped;

[0012] Step 3: After the delay ends, decide whether to continue dosing based on the signal status

[0013] As a preferred technical solution of the present invention, the step 1 involves equipment comprising a monitoring probe, a dosing device, an intelligent control module and a data storage module.

[0015] Dosing device: used for accurate dosing of flocculants or urease, with dynamic adjustment capability; Intelligent control module: integrates signal reception, logical judgment, dosing amount calculation, delay control and intelligent learning functions; Data storage module: records historical dosing data for optimization use by the intelligent control module.

[0016] As a preferred technical solution of the present invention, step three includes signal reception, dosage calculation, delay control, result judgment, and intelligent learning mechanism.

[0017] As a preferred technical solution of the present invention, the signal receiving: when the turbidity or urea exceeds the standard, the system sends an ON signal to start the dosing device;

[0018] Dosage calculation: Calculate the dosage according to the following formula:

[0019] Q_{\text{total}}=Q_{\text{theory}}+Q_{\text{adj ustment}};

[0020] Delay control: After the dosing is completed, the system enters the delayed observation stage (12-36 hours for turbidity and 8-24 hours for urea);

[0021] Result judgment: If the delay end signal is OFF, the system waits for the next ON signal; if the signal continues to be ON, the dosing is started again;

[0022] Intelligent learning mechanism: The system uses historical data to adjust the theoretical dosage and correction value, optimize the subsequent dosage strategy, and predict the optimal dosage by analyzing the previous turbidity reduction rate and dosage effect.

[0023] As a preferred technical solution of the present invention, the dosage is dynamically optimized by an intelligent learning mechanism, and the theoretical dosage and correction value are adjusted based on historical data.

[0024] As a preferred technical solution of the present invention, the delay stage is 12-36 hours for turbidity or 8-24 hours for urea. After the start command sends an ON signal, the dosing system will add the theoretical amount of turbidity urea plus the empirical correction value of water and then stop dosing. After 12-36 or 8-24 hours, if the start command is OFF, the dosing system waits for the next ON signal. If the command continues to be ON, it will start again. The start and stop of the dosing amount has an intelligent learning machine.

[0025] The beneficial effects of the present invention are:

[0026] After the start command sends an ON signal, the dosing system will dosing the corresponding agent according to the turbidity or urea theoretical amount plus the empirical correction value, and then stop dosing. After 12-36 or 8-24 hours, if the start command is OFF, the dosing system will wait for the next ON signal. If the command continues to be ON, the dosing will be started again. The start and stop of the dosage has an intelligent learning mechanism, and at the same time optimizes the dosage of agents (such as flocculants or urease) to avoid excessive dosage, improve water treatment efficiency and resource utilization, and have high practical value; turbidity control: by optimizing the dosage of flocculants, reduce water turbidity and avoid equipment blockage caused by excessive flocculants. Urea control: by optimizing the addition of urease, degrade urea in water, reduce the formation of chloramines and maintain water quality safety. BRIEF DESCRIPTION OF THE DRAWINGS
