Description

Technical Field

[0001] The present invention relates to the field of water management, and in particular to an intelligent water management system for a chemical park. Background Art

[0002] In the rapidly developing chemical industrial park, with the expansion of enterprise scale and the complexity of production activities, water management faces unprecedented challenges. The traditional water management model often relies on manual monitoring, empirical judgment and manual operation, which is not only inefficient, but also difficult to ensure water quality safety, water supply stability and environmental protection of wastewater treatment. Especially for chemical industrial parks, sewage will contain residual substances of chemical products, which is easy to cause environmental pollution, so sewage discharge detection is also a top priority.

[0003] The sewage from existing chemical parks is connected to the sewage treatment plant through a dedicated channel. When sewage is discharged, if there is a mistaken discharge, inadequate monitoring or damage to the control valve, some of the sewage that exceeds the standard will be directly discharged through the pipe, causing economic losses and pollution that are difficult to remedy.

[0004] Therefore, it is necessary to propose an intelligent water management system for chemical parks to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide an intelligent water management system for a chemical park, so as to solve the problem that the sewage in the existing chemical park is connected to the sewage treatment plant through an exclusive channel. When the sewage is discharged, if there is a mistaken discharge, the monitoring is not in place or the control valve is damaged, some of the sewage exceeding the standard will be directly discharged through the pipeline, causing economic losses and pollution that are difficult to remedy.

[0006] To achieve the above purpose, the present invention provides the following technical solution: a chemical park water affairs intelligent management system, comprising:

[0009] User terminals, including user terminal A, user terminal B, user terminal C... user terminal N, the user terminals are remotely connected to the server by signals, and the user terminals are used to form data interaction with the server, so that the server sends the collected water service data of each drainage node to the corresponding user terminal;

[0010] The temporary storage unit is used to temporarily store wastewater discharged from each drainage node in the park. When the information collection unit collects wastewater at the drainage node and it meets the standards, it is discharged to the treatment plant for final treatment; when the information collection unit collects wastewater at the drainage node and it does not meet the standards, the wastewater is discharged into the temporary storage unit until it meets the standards and is discharged to the treatment plant for final treatment;

[0011] Wherein, the information collection unit includes:

[0012] A detection device for detecting water quality data of wastewater;

[0013] A controller, used for receiving signals from the detection device and forming water service data;

[0014] A wireless communication unit, used for sending the water quality data detected by the detection device to a server;

[0015] The temporary storage unit includes a water storage tank and a monitoring and control subunit. The water storage tank is used to receive wastewater discharged from each drainage node, and the water storage tank is connected to the sewage treatment plant through a dedicated channel.

[0016] The monitoring and control subunit includes a second solenoid valve 300 arranged on the dedicated channel, and a wastewater detector and a water level meter arranged inside the water storage tank.

[0017] Preferably, the detection device and the wastewater detector both include a digital COD sensor for detecting chemical oxygen demand in wastewater, a flow meter for detecting wastewater flow, a pH sensor and a sewage sensor.

[0018] Preferably, a first solenoid valve 200 for controlling wastewater discharge is provided at each drainage node in the park, and the first solenoid valve is remotely signal-connected to a user terminal.

[0019] Preferably, the information collection unit also includes a locator 100, which is installed at the drainage node. The locator is used to monitor the location information of each drainage node.

[0021] Preferably, the server further comprises an alarm unit, which is used to identify whether the water quality data of the wastewater in the detection device exceeds the standard and satisfies the alarm condition, and the alarm signal of the alarm unit is displayed on the user terminal via a wireless signal.

[0022] Preferably, the flow meter is an electromagnetic flow meter.

[0023] Preferably, the exclusive channel is a one-way pipe, and the inner wall of the one-way pipe is coated with corrosion-resistant material, and the monitoring and control subunit and the server of the sewage treatment plant are connected by signal.

[0024] Preferably, the alarm unit and the central processing unit of the server are synchronized.

[0025] Technical effects and advantages of the present invention:

[0026] 1. In the actual operation of the present invention, when the water quality data of wastewater discharge in a certain node is abnormal, the central processing unit of the server detects the abnormal data and issues an alarm through the alarm unit. At the same time, the alarm unit also transmits the abnormal data to the user terminal. The user can close the first solenoid valve of the node through the user terminal, and stop the discharge of wastewater with abnormal data in time to avoid causing more serious economic losses and pollution.

[0027] 2. When the wastewater discharged from the node does not meet the standards, the wastewater will not be directly discharged to the treatment plant for final treatment after passing through the drainage node, that is, the third solenoid valve is closed and the second solenoid valve is opened, and the wastewater will enter the water storage tank for storage, waiting for the corresponding personnel of the park factory to treat the stored wastewater. It can be discharged to the treatment plant for corresponding treatment after meeting the standards, thereby reducing the pressure on the wastewater treatment plant. Based on the design of the present invention, the drainage node is a place for monitoring by the treatment plant, and it can accurately monitor whether the wastewater discharged by each park factory meets the standards. If it does not meet the standards, it will also be treated by the corresponding park factory. The sewage treatment can be connected to the monitoring and control sub-unit of the industrial and chemical park, and the water quality data of the discharged wastewater can be monitored in a targeted manner, which is convenient for the sewage treatment plant to access or conduct secondary treatment, thereby improving the transparency of the monitoring of wastewater discharged in the park and avoiding the phenomenon that the wastewater discharged by the park factory does not meet the standards and is directly discharged to the treatment plant without supervision.

[0028] 3. Through double monitoring and testing, it is ensured that sewage discharge meets the standards. By setting up a temporary storage unit, the sewage that exceeds the standard can be intercepted to avoid pollution caused by the sewage that is discharged by mistake, which is convenient for the factory to carry out intelligent management and control.

[0029] 4. The user terminal can use the locator to check the location of the node where the sewage is mistakenly discharged, so as to trace the root cause for improvement or monitoring, improve production efficiency, and facilitate personnel to carry out repairs, etc.

[0030] 6. Through integrated monitoring, storage and discharge, comprehensive intelligent management of the park’s water affairs is realized; it not only improves the real-time and accuracy of water quality monitoring, effectively ensures the safety of sewage discharge of enterprises in the park; and uses dual detection functions to reduce the possibility of discharging excessive sewage, achieving a win-win situation of economic and environmental benefits; in summary, the intelligent water management system of the chemical park provides strong support for the sustainable development of the park.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clarify the technical solutions in the embodiments of the present invention; it is clearly described in detail. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] The present invention provides Figure 1 - Figure 3 A chemical park water affairs intelligent management system shown includes: information collection units, including information collection units a, information collection units b, information collection units c...information collection units n, which are respectively used to collect water affairs data at each drainage node in the park;

[0037] The information collection unit includes: a detection device for detecting water quality data of wastewater; a controller for receiving signals from the detection device and forming water service data; a wireless communication unit for sending the water quality data detected by the detection device to a server;

[0038] In the actual operation of the present invention, it is necessary to pre-install a detection device on each drainage node of the chemical park. Specifically, the detection device includes a digital COD sensor for detecting the chemical oxygen demand in the wastewater, a flow meter for detecting the wastewater flow, a pH sensor and a sewage sensor. The pH sensor is used to detect whether the discharged wastewater reaches the pH value of the discharge standard, and the sewage sensor is used to detect whether the waste in the wastewater is within the discharge standard.

[0039] The server is used to receive the water service data collected by the information collection unit; the water service data includes wastewater detection data detected by a series of detections such as digital COD sensors, flow meters, pH sensors and sewage sensors.

[0040] User terminals, including user terminal A, user terminal B, user terminal C... user terminal N, the user terminals are remotely connected to the server by signals, and the user terminals are used to form data interaction with the server, so that the server sends the collected water service data of each drainage node to the corresponding user terminal;

[0041] In the actual operation of the present invention, the wastewater data of each node detected by the server can be transmitted to each user terminal through the conversion of the server. Each user terminal includes a mobile phone, a computer, etc. The user can observe and monitor the water data of each node in the park anytime and anywhere through the corresponding user terminal, without having to monitor at a specific workstation. At the same time, each staff member in the park can access the server through the local area network to view the wastewater discharge situation in the park.

[0042] A first solenoid valve 200 for controlling wastewater discharge is provided at each drainage node in the park, and the first solenoid valve 200 is remotely connected to the user terminal by signal to control the discharge of each drainage node.

[0043] The server includes a signal receiving unit, a central processing unit and an information storage unit. The receiving end of the signal receiving unit is connected to the output end of the wireless communication module. The central processing unit is used to process the water data of the signal receiving unit, and the information storage unit is used to store the water data of the signal receiving unit.

[0044] The server also includes an alarm unit, which is used to identify whether the water quality data of the wastewater in the detection device exceeds the standard to meet the alarm condition, and the alarm signal of the alarm unit is displayed on the user terminal through a wireless signal. The alarm unit and the central processing unit of the server are synchronized.

[0045] In the actual operation of the present invention, when the water quality data of wastewater discharge in a certain node becomes abnormal, the central processing unit of the server detects the abnormal data and issues an alarm through the alarm unit. At the same time, the alarm unit also transmits the abnormal data to the user terminal. The user can close the first solenoid valve 200 of the node through the user terminal, and stop the discharge of wastewater with abnormal data in time to avoid causing more serious economic losses and pollution.

[0046] A temporary storage unit is provided. When the wastewater collected by the information collection unit at the drainage node meets the standards, the wastewater is discharged to the treatment plant for final treatment. When the wastewater collected by the information collection unit at the drainage node does not meet the standards, the wastewater is discharged into the temporary storage unit until it meets the standards and is discharged to the treatment plant for final treatment. The temporary storage unit includes a water storage tank and a monitoring and control subunit. The water storage tank is used to receive wastewater after each drainage node, and the water storage tank is connected to the sewage treatment plant through an exclusive channel. There are multiple water storage tanks, and the multiple water storage tanks are respectively connected to the corresponding nodes through pipelines, and each node is also connected to the wastewater treatment plant through a pipeline, and a third solenoid valve is provided at the connection between each node and the wastewater treatment plant.

[0047] The sewage discharged from each node will enter the corresponding temporary storage unit, that is, the inside of the water storage tank, and will be stored for a certain period of time. For example, when the wastewater in the park factory is discharged without discharge or detection, the discharged wastewater will not meet the standards. When it does not meet the standards, the wastewater will not be directly discharged to the treatment plant for final treatment after passing through the drainage node, that is, the third solenoid valve is closed, and the wastewater will enter the water storage tank for storage. It is necessary to wait for the corresponding personnel of the park factory to treat the stored wastewater, and it can be discharged to the treatment plant for corresponding treatment after it meets the standards;

[0048] The pressure on the wastewater treatment plant is reduced; based on the design of the present invention, the drainage node is the place where the treatment plant is monitored, and at the same time, it can accurately monitor whether the wastewater discharged by each factory in the park meets the standards. If it does not meet the standards, it will be treated by the corresponding factory in the park, which increases the transparency of monitoring and avoids the phenomenon that the wastewater discharged by the factory in the park does not meet the standards and is directly discharged to the treatment plant without supervision;

[0049] The monitoring and control subunit includes a second solenoid valve 300 arranged on a dedicated channel, and a wastewater detector and a water level meter arranged inside the water storage tank. The flow meter uses an electromagnetic flow meter.

[0050] The electromagnetic flow meter can monitor the internal capacity of the water storage tank in real time. When the capacity is about to reach the limit, it can be reflected on the user terminal through the server to issue an early warning.

[0051] At the same time, the sewage entering the water storage tank will also be detected by the wastewater detector in the water storage tank. The wastewater detector and the detection device use the same device, including a digital COD sensor for detecting the chemical oxygen demand in the wastewater, a flow meter for detecting the wastewater flow, a pH sensor and a sewage sensor to monitor the sewage stored in the water storage tank in real time.

[0052] Through dual monitoring and testing, it is ensured that sewage discharge meets the standards. By setting up a temporary storage unit, the sewage that exceeds the standard can be intercepted to avoid pollution caused by the sewage that is discharged by mistake, which facilitates the factory to carry out intelligent management and control.

[0053] If the waste water inside the water storage tank does not meet the discharge standard, the user terminal can control the second solenoid valve 300 to close and perform secondary interception on the discharged waste water.

[0054] At the same time, the information collection unit also includes a locator 100, which is installed at the drainage node. The locator 100 is used to monitor the location information of each drainage node. The locator 100 and the server are connected through remote signals, so that the server obtains the location information of the locator 100 and transmits it to the user terminal through remote signals. The user terminal can check the location of the node where the sewage is mistakenly discharged through the locator 100, which is convenient for tracing the root cause for improvement or monitoring, and improving production efficiency. It is convenient for personnel to carry out repairs and other links.

[0055] The exclusive channel is a one-way pipe, and the inner wall of the one-way pipe is coated with corrosion-resistant material. The monitoring and control sub-unit and the server of the sewage treatment plant are connected by signal.

[0056] By connecting to the monitoring and control sub-unit of the chemical park, sewage treatment can monitor the water quality data of discharged wastewater in a targeted manner, facilitate sewage treatment plant access or secondary treatment, and improve the transparency of wastewater discharge monitoring in the park.

[0057] Through integrated monitoring, storage and discharge, comprehensive intelligent management of the park's water affairs is achieved; it not only improves the real-time and accuracy of wastewater monitoring, effectively ensures the safety of wastewater discharge of enterprises in the park; and uses dual detection functions to reduce the possibility of discharging excessive wastewater, achieving a win-win situation of economic and environmental benefits; in summary, the chemical park's intelligent water management system provides strong support for the sustainable development of the park.
