[Smart environmental protection] Water pollution monitoring of hydrological environment monitoring system

1. System introduction

The hydrological automatic monitoring system is a comprehensive online automatic monitoring system composed of online automatic analysis instruments, using modern automatic monitoring technology, automatic control technology, computer application technology, related special analysis software and communication network locks. The system realizes automatic collection and pretreatment of water samples and air, automatic collection and storage of monitoring data, and provides remote transmission interfaces and control interfaces. The automatic hydrological detection system can achieve real-time, continuous monitoring and trajectory monitoring. It can timely grasp the key sections of the main river basin and the water quality status of the water source, early warning and forecasting major river basin water pollution accidents, and controlling the water quality status of the water source when major water pollution occurs. , The purpose of solving sudden water pollution accidents.

Hydrological monitoring and early warning system

Design principles of monitoring and early warning system:

1. Reliability: This system is mainly used for the monitoring of water pollution, dispatching personnel to inspect on site in time, and taking water quality protection measures. Therefore, the reliability of the entire system is our first consideration.

2. Advancement: Technology is constantly progressing against war. The principle of the technology and equipment we choose is the most advanced at present, and at least its advancement should be guaranteed for a period of time.

3. Practicability: The selected equipment conforms to China's national conditions and the actual situation of the production unit, and Mazu customers need to choose equipment with good cost performance.

4. Compatibility: With the continuous upgrade and expansion of the transformation, the system should ensure that it can be upgraded and expanded, and the audit of the system should minimize the investment cost of the upgrade.

5. Extensibility: The design of the system adopts a modular structure, which can be easily implemented if the customer has functional changes.
