A certain township's economy is primarily based on mushroom cultivation, supplemented by various small-scale livestock farming operations. This has led to the direct discharge of mushroom farm wastewater and livestock wastewater, which easily pollutes the surrounding watershed. To address this, a new constructed wetland treatment system has been built to channel mushroom and livestock wastewater into the wetland for purification. This process removes pollutants such as nitrogen and phosphorus from the water, effectively reducing pollution and supporting the development of a "Beautiful Countryside" initiative.

To better uate the effectiveness of the constructed wetland treatment system, a real-time water quality monitoring system is required on-site. This system will enable real-time monitoring and centralized data management of water quality in the surrounding watershed, helping guide further ecological treatment strategies. WideIOT provides a low-cost, high-performance hydrological and water resources RTU (Remote Terminal Unit) that collects data from multiple water quality analyzers and transmits it to the environmental protection department's management platform. This creates a real-time, shared IoT network and promotes the digital transformation of ecological management.

Key Features

1. Real-Time Multi-Parameter Water Quality Monitoring

The system connects to water quality analyzers measuring parameters such as dissolved oxygen, pH value, turbidity, ammonia nitrogen, total phosphorus, total nitrogen, and COD (Chemical Oxygen Demand). It automatically collects and uploads real-time water quality data from the wetland inlet, outlet, and key sections of the watershed, providing a comprehensive view of pollution treatment efficiency.

2. Remote Data Transmission and Centralized Management

Using the hydrological RTU, collected water quality data is transmitted in real-time via 4G/5G networks to the environmental protection department's supervision platform (using the HJ212 protocol) and a local management backend. This enables unified aggregation, storage, and management of data from multiple sites, eliminating data silos.

3. Visual Data Display and Trend Analysis

With map-based and dashboard-style visualization interfaces, the platform dynamically displays water quality trends, time-period comparisons, and exceedance alerts for each monitoring point. This helps management personnel intuitively understand treatment effectiveness.

4. Anomaly Alarms and Event Tracking

Customizable water quality thresholds are supported. When a parameter exceeds the threshold or equipment malfunctions, the system automatically sends alerts via SMS, WeChat, or email. Historical events are logged, facilitating rapid source tracing and corrective action.

5. Data Reports and Treatment Effectiveness Assessment

The platform automatically generates daily, weekly, and monthly statistical reports, including key performance indicators such as pollutant removal rates and compliance rates. These reports support the optimization of wetland operations and adjustments to pretreatment measures for mushroom and livestock wastewater.

6. Multi-Level Access and Remote Maintenance

Role-based access control is provided for different users, including environmental protection department staff, township management personnel, and third-party operation and maintenance teams. The solution also includes remote gateway status monitoring, parameter configuration, and fault diagnosis features, reducing on-site maintenance costs.
