Rural distributed wastewater treatment stations play a critical role in addressing the persistent challenge of untreated sewage in rural areas. Without proper treatment, freely discharged wastewater accumulates over time, degrading the environment and jeopardizing residents’ health. As a key component of rural habitat improvement, these decentralized treatment systems align with China’s “14th Five-Year Plan,” which prioritizes resolving longstanding issues like black, odorous water bodies. By implementing efficient rural distributed wastewater treatment stations, communities can significantly enhance ecological protection while meeting national environmental governance objectives, creating cleaner, healthier living spaces for rural populations.
Rural distributed wastewater treatment stations face the following pain points: ① the scale of each point is small, only about 10~30 tonnes per day; ② more points, it is difficult to carry out unified management of all the points; ③ unmanned operation, so the automation of the treatment station and remote operation and maintenance requirements are higher.
The traditional rural distributed sewage treatment station usually adopts PLC for overall control and operation, which requires high programming level for technicians, and remote operation and maintenance is difficult to realise, and unified management is more difficult.
IOTROUTER for the above pain points, according to the actual application of rural distributed sewage treatment station designed a set of intelligent sewage treatment control cabinet, greatly enhancing the intelligent level of rural distributed sewage treatment station.
Intelligent Solution for Rural distributed wastewater treatment stations
IOTROUTER uses gateway de computação periférica EG8000 and IO expansion module ET1010 to build an intelligent sewage treatment control cabinet, and combines with the IoT platform IOTRouter Cloud to realise the unified management of sewage points and the remote operation and maintenance of the system.
Using the characteristics of EG8000 to support remote writing commands, combined with ET1010 control extension module, the command is issued through the IOTRouter IoT platform to control the AC contactor in the traditional control cabinet, thus realising the remote control of each production equipment in the wastewater treatment station, and solving the problem that the traditional PLC wastewater treatment control cabinet is unable to be controlled remotely and managed in a unified way. The control cabinet supports access to PH, dissolved oxygen, water level and other sensors, providing real-time collection of sewage monitoring data and data transmission capabilities.
Programme Advantages
Automated operation: The control cabinet can achieve automated operation, monitoring the status of various devices and sensors inside the pumping station, such as pump current, temperature, pressure, etc., as well as flow, level sewage total nitrogen phosphorus, ammonia nitrogen and other key parameters.
Response low latency: Edge computing can reduce data transmission time, improve response speed and real-time, and effectively improve the response rate of the equipment through data processing on the device side.
Remote operation and maintenance: The control cabinet can be programmed and adjusted remotely according to the demand, and combined with IOTRouter IoT platform to achieve remote intelligent control. It supports intranet penetration to provide users with secure remote management, configuration, upgrading and programming.
Drag-and-drop programming: EG8000mini in the control cabinet provides a browser-based process editor with rich panel nodes, free formation of processes, and one-click deployment and operation.
Disconnection: Edge computing gateway EG8000mini can cache data in case of network anomaly and report data when the network is restored.
Unified management: IOTRouter Cloud can handle the connection and management of millions of devices through clustering, and supports the aggregation of data from multiple devices for unified management of each point.
Programme Benefits
1. Remote control: Support remote control function of electrical equipment in sewage treatment stations to achieve unified control and management of decentralised sewage treatment stations.
2. Remote operation and maintenance: Provide simple, efficient, stable and safe intranet penetration function to reduce the difficulty of sewage treatment station equipment operation and maintenance.
3. Data security: Provide the ability to continue transmission of data over the network, avoiding the loss of important data collected by the front-end equipment of the sewage treatment station due to network problems, and improving the system’s ability to resist risks.
4. Real-time early warning: To achieve the distributed sewage treatment station water quality, sewage PH value and other data exceeding the active alarm.
5. Unified management: Achieve unified management of distributed sewage treatment station equipment to achieve more efficient management and operation.
6. Cost savings: Reduce the overall access costs of the system, support for remote operation and maintenance reduces the cost of operation and maintenance, unified management of equipment reduces the cost of system management.
With the deep integration of IoT and edge computing technologies, rural distributed wastewater treatment stations are embracing a new era of intelligent transformation. The synergy between EG8000 edge computing gateways, ET1010 control extension module, and IoT platforms not only resolves traditional system limitations like remote maintenance difficulties and fragmented management, but also delivers a cost-effective solution through its “data-driven + smart control” innovation. This system fulfills both the automation needs of unmanned stations and centralized management of decentralized facilities via cloud-edge collaboration, bringing technological warmth and practical results to the protection of rural water ecosystems.
