The sewage treatment industry, as one of China's new strategic industries, has received high attention from the country in the 12th Five Year Plan, especially with stricter requirements for rural sewage treatment. It is clearly stipulated that county-level towns and key towns must establish sewage treatment plants. By April 2023, the number and treatment capacity of sewage treatment plants nationwide have shown a rapid growth trend.
Therefore, Modbus IoT platform technology follows the forefront of sewage treatment technology and has mastered the overall solution of a comprehensive operation and management platform for sewage treatment based on IoT.##Project OverviewThis project utilizes Internet of Things technology to focus on the perception and management of sewage treatment facilities. Intelligent sensors are used to collect water quality information (including CODcr, BOD, SS, NH3-N, etc.) online at deployment sites. At the same time, existing control equipment is integrated and renovated to achieve intelligent sensing and scientific management of sensors. Administrators can real-time monitor the status information of smart sensor devices through information terminals such as mobile phones and computers, receive abnormal alarm information in a timely manner, and remotely control devices based on monitoring results to achieve real-time monitoring and timely control.##Problems and optimization solutions in traditional sewage treatmentThe traditional sewage treatment system has the following main problems:
##Detailed explanation of scheme optimizationWe provide detailed protocols for this solution and can change the address of the gateway reporting server. The device can directly change the data receiving server address to a privately deployed "sewage treatment system platform" provided by the Modbus IoT platform through the gateway's parameter setting software. The Modbus IoT platform connects the data paths between various types of gateways and platforms, sets up dedicated model drivers for each type of gateway, and solves existing problems at the device layer, control layer, gateway layer, and multi system layer:##System design principles and functionsOur system design follows the following principles:
Policy and Technology Update in 2026
The newly revised "Management Measures for the Operation of Rural Domestic Sewage Treatment Facilities" by the state in 2025 further strengthens theRequirements for online monitoring coverage- All facilities with a daily processing capacity of 20 tons or more must be connected to the regulatory platform to achieve real-time data upload.
At the technical level, theedge computing+Internet of Thingsarchitecture has become the industry standard configuration. The sensors (flow meters, level gauges, water quality monitors) of Modbus RTU protocol are connected to the edge gateway through RS485 bus. After the gateway completes data cleaning and abnormal judgment locally, only key data is reported to the cloud - this solution reduces traffic while ensuring system availability in offline scenarios.
