Tianjin Zwinsoft Technology Co., Ltd Flood Characteristics Water Quality Monitoring Solution

1. Background of the Project

Floods are a common natural disaster. Whenever floodwaters recede, carrying with them pollutants such as surface mud, garbage, domestic sewage, and industrial wastewater, not only are the streets and alleys devastated, but rivers, lakes, reservoirs and other water bodies are also at risk of deterioration, directly threatening drinking water safety, the ecological environment and public health.

Traditional water quality monitoring methods suffer from slow response, low frequency, and difficulty in preserving evidence, making them unable to meet the demands of “rapid perception, accurate tracing, and effective response” during floods. To address this, Zhiyi Times, leveraging over a decade of experience in online environmental monitoring, has launched a flood-specific water quality monitoring solution. This solution, centered around independently developed flood-specific water quality monitoring stations, achieves a closed-loop process of “real-time monitoring, intelligent sampling, and data support,” providing precise and efficient water quality management tools for management departments at all levels.

2. Program objectives

(1)Real-time perception: Using reagent-free in-situ monitoring, water quality changes can be detected within minutes, and abnormalities exceeding the standard can be quickly warned.

(2)Evidence retention: Supports multiple sampling modes such as sampling for exceeding standards and sampling for triggering, which can effectively solve problems such as “difficulty in tracing the source of pollution incidents and lack of basis for law enforcement”.

(3)Data support: Provides reliable data for routine monitoring, emergency response, law enforcement supervision, traceability analysis and other scenarios, facilitating scientific management decisions.

3. Product application

The core supporting equipment of this solution is the  Tianjin Zwinsoft Technology Co., Ltd flood characteristic water quality monitoring station. In view of the large fluctuations in water quality and complex pollutants during floods, it integrates nine water quality monitoring indicators and three core functions: minute-level monitoring, intelligent sampling, and data traceability, perfectly matching the needs of flood water quality monitoring.

 

Tianjin Zwinsoft Technology Co., Ltd Flood Characteristic Water Quality Monitoring Station uses optical and electrode analytical technologies for reagent-free, in-situ monitoring of water bodies. It supports customizable water quality indicators such as dissolved oxygen, turbidity, COD, ammonia nitrogen, total nitrogen, total phosphorus, conductivity, temperature, and pH. During the water collection process, no pretreatment is required, and samples can be tested up to every 10 minutes, with a customizable frequency. The core sensor has an IP68 protection rating and is constructed of corrosion-resistant materials to meet the monitoring needs of various water bodies and scenarios. The on-site data is equipped with an intelligent color touchscreen for convenient data viewing and device debugging. It also integrates an IoT communication module to support remote data transmission and control. This system provides data support for management departments at all levels for routine monitoring, emergency monitoring, law enforcement monitoring, source tracing monitoring, and spot checks.

• It has water level monitoring and flow monitoring functions. When the water level or flow is lower than the set threshold, the system automatically stops running and records the operation log.
• It has the function of automatic data retransmission. In the event of communication abnormalities, the data is stored locally and automatically resent after communication is restored to prevent data loss.
• It has data and operation log storage function, and can store up to 10 years of operation data.

   Advantages of the Solution

• Minute-level response, seize the initiative in emergency handling

Traditional monitoring requires manual sampling and laboratory analysis, which is extremely time-consuming. However, this solution can detect water quality abnormalities within 5 minutes through real-time monitoring and start sampling within 10 minutes, providing “first-hand data” to emergency departments, allowing them to quickly determine the degree of pollution and initiate corresponding disposal measures.

• Multi-parameter synchronization to accurately characterize water quality characteristics

Water quality fluctuates complexly during floods. This solution supports simultaneous monitoring and cross-validation of multiple water quality indicators, including dissolved oxygen, turbidity, COD, ammonia nitrogen, total nitrogen, total phosphorus, conductivity, temperature, and pH, to avoid misjudgment based on a single parameter. Furthermore, the intelligent sample retention function ensures the accuracy of “abnormal samples,” providing reliable material for subsequent laboratory analysis.

• Traceability solves law enforcement and tracing problems

In traditional monitoring, “sample loss and incomplete records” are common obstacles to law enforcement. This solution ensures that every abnormal event has evidence support and a traceable source through full-link traceability of “data-sample-record”.

• Multi-scenario adaptation, covering the entire management process

The solution supports five monitoring scenarios, covering the full process needs of management departments:

Routine monitoring: Long-term deployment of monitoring points in flood-prone areas to monitor water quality baselines in real time and provide data for daily management;

Emergency monitoring: Modular design and easy installation allow for rapid deployment and real-time data transmission when floods occur, helping emergency departments dynamically adjust response strategies.

Law enforcement monitoring: In response to public reports and suspected pollution incidents, monitoring data and sample records can be quickly retrieved as a basis for law enforcement;

Source tracing monitoring: Through real-time data changes and sample analysis, the pollution source can be traced throughout the entire chain;

Spot check monitoring: Randomly check key areas to quickly obtain real-time data, verify water quality conditions, and improve spot check efficiency.

   Application Value

This solution solves the “pain points” of water quality monitoring during floods for management departments at all levels through the “real-time monitoring – intelligent sampling – data traceability” capabilities of the Tianjin Zwinsoft Technology Co., Ltd flood characteristic water quality monitoring station:

(1)for environmental protection departments: provide a “chain of evidence” for pollution incidents to support law enforcement and accountability;

(2)for water conservancy departments: monitor the water quality of reservoirs and rivers in real time to ensure the safety of drinking water sources;

(3)for emergency departments: quickly obtain data, initiate disposal measures, and reduce the impact of disasters;

(4)for the public: enhance confidence in water quality safety through data disclosure.
