Water quality monitoring plan for flood characteristics in the era of Zhiyi: using "intelligence" to control floods and "quantity" to ensure safety

1、 Background of the plan

Flood disasters are common natural disasters in China,wheneverFloods carry surface sedimenttrashDomestic sewage, industrial wastewater, etcpollutantInflow into rivers, lakes, and reservoirs,metropolisCausing deterioration of water quality, directly threatening drinking water safety, ecological environment, and public health.

The traditional water quality monitoring methods have pain points such as slow response, low frequency, and difficulty in retaining evidence, which cannot meet the needs of "rapid perception, accurate traceability, and effective disposal" during floods and waterlogging periods. To this end, Zhiyi Era has launched a flood characteristic water quality monitoring program, relying on independently developed flood characteristic water quality monitoring stations to achieve a full process loop of "real-time monitoring intelligent sample retention data support", providing accurate and efficient water quality management tools for management departments at all levels.

2、 Program objectives

1. Real time perception: In situ monitoring of test free agents，minute-leveldetectionWater quality changes, rapid warningexceed the standardabnormal.

2. Evidence retention: multiple retention modes such as exceeding standard retention and triggering retention，Can be effectiveSolving the problem of "difficult traceability of pollution incidents and lack of basis for law enforcement"waitproblem.

3. Data support: Provide reliable data for routine monitoring, emergency response, law enforcement supervision, traceability analysis, and other scenarios to assist in scientific management decision-making.

3、 Product application

The core supporting equipment of this plan is the Zhiyi Era Flood Characteristic Water Quality Monitoring Station, which targets the large fluctuations in water quality and complex pollutants during floodswaitFeatures, integrationNine itemsWater quality monitoring indicators，The three core functions are minute level monitoring, intelligent sample retention, and data traceability,Match the needs of flood water quality monitoring.

The water quality monitoring station for flood characteristics in the Zhiyi era adopts analysis techniques such as optical method and electrode method，In situ monitoring of water bodies without test agents，Support dissolved oxygen、turbidityTheCOD、ammonia nitrogen、Total Nitrogen、Total Phosphorus、Monitoring of multiple water quality indicators such as conductivity, temperature, and pH，Indicators can be customized；During the collection process，Water samples do not require pre-treatment，It can be tested once every 10 minutes at most，Testing frequency can also be set according to user needs.The core sensor has an IP68 protection level and is made of corrosion-resistant materials，To meet the monitoring needs of different water bodies and scenarios, the on-site data is equipped with an intelligent color touch screen，Convenient for data viewing and device debugging, while integrating IoT communication modules to support remote data transmission and control. Provide data support for various levels of management departments for routine monitoring, emergency monitoring, law enforcement monitoring, traceability monitoring, spot check monitoring, etc.

Equipped with water level monitoring and flow monitoring functions, the system automatically stops running and records operation logs when the water level or flow falls below the set threshold.

Equipped with automatic data transmission function, in case of communication abnormalities, data is stored locally and automatically reissued after communication is restored to prevent data loss.

Equipped with data and operational log storage capabilities, it can store up to 10 years of operational data.

4、 Advantages of the plan

1. Fast ": Minute level response, seize the opportunity for emergency response

Traditional monitoring requires manual sampling、Laboratory analysis，extremely time-consumingThrough real-time monitoring, this plan can detect water quality abnormalities within 5 minutes and activate sample retention within 10 minutes, providing "first-hand data" for emergency departments to quickly determine the degree of pollution，Initiate corresponding disposal measures.

2. Accurate: Multi parameter synchronization, precise characterization of water quality characteristics

During floods, water quality changes are complex (such as increased turbidity affecting the determination of COD and dissolved oxygen), and this plan supports dissolved oxygen、turbidityTheCOD、ammonia nitrogen、Total Nitrogen、Simultaneous monitoring and cross validation of multiple water quality indicators such as total phosphorus, conductivity, temperature, and pH to avoid misjudgment of a single parameter. At the same time, the intelligent sample retention function ensures the accuracy of "abnormal samples" and provides reliable materials for subsequent laboratory analysis.

3. 'Reality': Traceability, solving the problem of law enforcement and traceability

In traditional monitoring, "sample loss and incomplete recording" are common obstacles to law enforcement. This solution ensures that every abnormal event is supported by evidence through the full chain traceability of "data sample record"、There is a source to trace.

4. 'Full': Multi scenario adaptation, covering the entire management process

The plan supports five monitoring scenarios, covering the full process requirements of the management department:

o Routine monitoring: Long term deployment in flood prone areas (such as river banks and reservoir entrances), real-time monitoring of water quality baseline, providing data for daily management;

o Emergency monitoring:Modular design, easy installation, whenWhen floods occur,canRapid deployment, real-time data transmission, helping emergency departments dynamically adjust disposal strategies;

o Law enforcement monitoring: In response to reports from the public and suspected pollution incidents, quickly retrieve monitoring data and sample records as a basis for law enforcement;

o Traceability monitoring: through real-time data changes，Based on sample retention analysis, trace the source of pollution (such as industrial enterprises, livestock and poultry farms);

o Spot check monitoring: For key areas such as drinking water sources and farmland irrigation areas, real-time data can be quickly obtained during random checks to verify water quality and improve inspection efficiency.

fiveApplication value

This plan solves the "pain points" of water quality monitoring during floods for management departments at all levels through the "real-time monitoring intelligent sample retention data traceability" capability of the Zhiyi Era flood characteristic water quality monitoring station:

· To the environmental protection department: provide a "chain of evidence" for pollution incidents to support law enforcement and accountability;

· For the water conservancy department: real-time monitoring of reservoir and river water quality to ensure the safety of drinking water sources;

· For emergency departments: quickly obtain data, initiate response measures, and reduce the impact of disasters;

· To the public: Enhance confidence in water quality safety through data disclosure.
