Description

Technical Field

[0001] The invention relates to the field of water quality detection for water purification plants, in particular to a water quality detection device for water purification plants. Background Art

[0002] With the rapid development of social economy and the continuous growth of population, the demand for water resources is increasing, and the requirements for water quality are also getting higher and higher. As an important link in ensuring the safety of residents' water use, water quality testing in water treatment plants is of vital importance. Traditional water quality testing methods usually rely on laboratory analysis. Although this method is accurate, it has the disadvantages of long testing cycle and complex operation, and cannot reflect water quality changes in real time. In order to achieve real-time monitoring of water quality in water treatment plants, improve water treatment efficiency and ensure water supply quality, it is imperative to develop an efficient and accurate water quality testing device. The development of sensor technology and automatic control technology has provided strong support for the innovation of water quality testing devices. The new water quality sensor can quickly and sensitively detect a variety of water quality parameters, including pH, dissolved oxygen and turbidity, and can detect water quality abnormalities in time and issue early warnings.

[0003] With the rise of Internet of Things technology, water quality testing devices have gradually achieved remote monitoring, allowing managers to understand the water quality status of water treatment plants anytime and anywhere, make timely decisions and adjust treatment processes. Summary of the invention

[0004] In order to solve the technical problems raised by the above background technology, the present invention provides a water quality detection device for a water purification plant.

[0005] The purpose of the present invention can be achieved through the following technical scheme: The present invention is a water quality detection device for a water treatment plant, including a pretreatment module, a data acquisition module, a chemical analysis module, a regulation module, an early warning processing module, a remote monitoring module, a data center and a water treatment plant control center.

[0006] The preprocessing module preprocesses the raw water detection source according to the acquired raw water detection source, obtains the purified water detection source and transmits it to the data acquisition module. The specific acquisition steps are as follows:

[0007] The input end of the pretreatment module is connected to the output end of the water treatment plant control center. The water treatment plant control center sends a water outlet control instruction to the water inlet pool control terminal. The water treatment pool control terminal receives the water outlet control instruction, fills the water treatment pool with water, and obtains the raw water detection source. The water inlet pool control terminal pre-treats the obtained raw water detection source, controls the grid filtration of the water inlet pool to remove solid impurities in the raw water detection source, including branches, leaves and garbage, and then transports the treated raw water detection source to the grit tank to precipitate and remove heavier sand and inorganic particles in the water. Then, through wet digestion, a mixed acid of nitric acid and perchloric acid is used to completely decompose the organic matter in the raw water detection source, and convert the metal elements therein into a measurable ionic state, obtain the purified water detection source, and transport it to the water treatment pool. According to this step, multiple purified water detection sources within a specific time period are obtained.

[0008] The data acquisition module collects data from each water purification detection source after processing and sends it to the chemical analysis module. The specific acquisition process is as follows:

[0009] The input end of the preprocessing module is connected to the output end of the data acquisition module, and the input end of the data acquisition module is connected to the output end of the water treatment plant control center. The water treatment plant control center sends a sampling instruction to the automatic sampling device of the corresponding water purification pool. The automatic sampling device receives the sampling instruction and collects the corresponding clean water sample. According to this step, multiple clean water samples within a specific time period are obtained, and the data acquisition module obtains multiple clean water samples within a specific time period.

[0010] The hydroxide ion concentration of each purified water sample in a specific period of time is measured by an ion chromatograph to obtain the hydroxide ion concentration corresponding to each purified water sample.

[0011] The turbidity degree of each purified water sample in a specific period of time is measured by a turbidity sensor to obtain each turbidity parameter value of each purified water sample in the specific period of time.

[0012] The dissolved oxygen content of each clean water sample in a specific period of time is measured by a dissolved oxygen sensor, and the dissolved oxygen parameters corresponding to each clean water sample are obtained.

[0013] The chemical analysis module performs analysis based on the parameter values ​​obtained by the data acquisition module. The specific acquisition method is as follows:

[0014] The input end of the chemical analysis module is connected to the output end of the data acquisition module to obtain the hydroxide ion concentration corresponding to each clean water sample in a specific period of time of the data module, and the pH value corresponding to each clean water sample is calculated according to the hydroxide ion concentration, specifically:

[0017] S3: pH calculated by the obtained hydrogen ion concentration = -log 10 ×[H + ] Obtain the pH value of each purified water sample;

[0018] S4: Extract the preset pH threshold of the data center, and compare the preset pH threshold with the actual pH threshold. If the preset pH threshold is greater than the actual pH threshold, it means that the corresponding clean water sample is acidic, and an acidic signal is generated and sent to the adjustment module. On the contrary, it means that the clean water sample is alkaline, and an alkaline signal is generated and sent to the adjustment module.

[0019] The turbidity parameter values ​​of each clean water sample obtained by the data acquisition module are extracted and analyzed, specifically:

[0020] T1: Set each turbidity parameter value as Ca, a=1, 2, ..., n, and count the number of all obtained turbidity parameter values, marked as CK;

[0021] T2: sorting the obtained turbidity parameter values ​​according to the time sequence of acquisition and connecting them in sequence to obtain a turbidity parameter waveform diagram;

[0022] T3: Analyze according to the turbidity parameter waveform. If the turbidity parameter decreases over time, it means that the water quality of the clean water detection source is gradually becoming clean. If the turbidity parameter is stable over time, it means that the water quality of the clean water detection source is relatively stable. If the turbidity parameter increases over time, execute T4.

[0023] T4: Get the maximum value of the turbidity parameter according to the obtained turbidity parameter waveform, marked as K ca At the same time, obtain the corresponding time period of the turbidity parameter rise in the turbidity parameter waveform, add all the corresponding time periods to get the total turbidity rise time period, marked as GH, and calculate using the formula An abnormal rise value is obtained, wherein L1, L2 and L3 are respectively preset proportional coefficients; an abnormal rise signal is generated from the obtained abnormal rise value and sent to the early warning processing module.

[0024] The data acquisition module obtains the dissolved oxygen parameters of each clean water sample, extracts the preset dissolved oxygen threshold of the data center, and compares the dissolved oxygen parameters of each clean water sample with the preset dissolved oxygen threshold. If the dissolved oxygen parameters of each clean water sample are greater than the preset dissolved oxygen threshold, it means that the water body is relatively clean. Otherwise, a processing signal will be generated and sent to the early warning processing module.

[0026] The output end of the chemical analysis module is connected to the input end of the regulation module, and the output end of the regulation module is connected to the input end of the water treatment plant control center. If the corresponding water treatment detection source receives an acid signal, the acid signal is sent to the water treatment plant control center. The water treatment plant control center receives the acid signal and generates an acid adjustment signal, which is sent to the control terminal of the acid-base storage tank to extract the acid adjustment value preset by the data center. The acid-base storage tank adds alkaline substances to the corresponding water treatment detection source through a pipeline. The alkaline substances include lime, sodium hydroxide and sodium carbonate, which react with the acidic wastewater to adjust the pH value to neutral.

[0027] When an alkaline signal is received, the alkaline signal is sent to the water treatment plant control center. The water treatment plant control center receives the alkaline signal and generates an alkaline adjustment signal and sends it to the control terminal of the acid-base storage tank, extracts the alkaline adjustment value preset by the data center, and the acid-base storage tank adds acidic substances to the corresponding water purification detection source through a pipeline. Acidic substances include hydrochloric acid and sulfuric acid, which react with alkaline wastewater to reduce the pH value.

[0029] The input end of the early warning processing module is connected to the output end of the chemical analysis module, and the output end of the early warning module is connected to the input end of the water treatment plant control center. When the early warning processing module receives the processing signal, it sends the processing signal to the water treatment plant control center. The water treatment plant control center receives the signal and generates an open command to send to the aeration device corresponding to the water purification detection source. The aeration device generates a large number of fine bubbles through compressed air to increase the gas-liquid contact area, and the water purification detection source increases the dissolved oxygen content.

[0030] When the early warning module receives an abnormal rising signal, it sends the abnormal rising signal to the maintenance personnel's mobile terminal. The maintenance personnel's mobile terminal receives the signal to detect the turbidity rising signal and feeds back the processing result to the data center. The maintenance personnel sends the processing instruction to the water treatment plant control center. The water treatment plant control center sends the signal to the corresponding pipeline. The pipeline adds coagulant and flocculant to the clean water detection source with higher turbidity for coagulation and flocculation reaction, and then filters it through a sand filter to obtain the clean water standard.

[0031] The remote monitoring module is used to allocate monitoring permissions according to positions. Each staff member can remotely monitor the water quality in real time through computers and mobile terminals. The specific acquisition process is as follows:

[0032] The output end of the remote monitoring module is connected to the input end of the water treatment plant control center. Different levels of user permissions are set up according to the position of each staff member, including administrators, operators and viewers.
