Water quality inspection equipment on board to ensure Chaohu environmental emergency monitoring

In order to protect the environment of Chaohu Lake, Chaohu Environmental Protection Environmental Monitoring Station of Anhui Province has begun to use "Nanjing Supervision Supervising No. 1". The ship was completed in July and entered Chaohu to begin operations. A reporter visited the ship directly and found that the vessel was equipped with a multi-functional water quality analyzer, a portable spectrophotometer, a biological toxicity analyzer, a portable dissolved oxygen analyzer, and an emergency monitoring box. Routine monitoring of water quality and emergency monitoring provide assurance.

According to reports, "Zhonghuanjian No. 1" has a low draught, a wind-resistant wave rating of no less than 6 and a strong endurance. The scope of monitoring can cover the entire lake. The new monitoring vessel fills the gap in the Chaohu water flow and real-time warning, improves the early warning level of Chaola algae, and ensures the safety of drinking water for Chaohu citizens.

The following is part of the media coverage:

At the end of July, the cyanobacteria in Chaohu Lake surface “rising” due to the continuous high temperature weather. At present, Chaohu City's environmental protection agencies are ready for emergency and urban drinking water is not affected.

The temperature has risen and the heat is pressing. Recently, the reporter followed Chaohu City Environmental Monitoring Station monitoring personnel boarded the berth at the shore of the Chaohu Lake, "Nest ring prison No. 1." This is a water quality emergency monitoring vessel with a length of more than 30 meters. It is divided into two layers: the first layer is the experimental area, sample storage area, operation area and living area, and the second layer is the conference room. According to reports, the total cost of the ship is 3.7 million yuan. In July this year, it was completed and built into Chaohu to begin operations.

“Previously, after we collected water samples in the lake, we had to send them back to the monitoring station's laboratory for testing. It was time-consuming and labor-consuming; now, routine testing is done directly on board and results can be produced immediately.” On duty on board City Environmental Protection Environmental Monitoring Station Engineering teacher Zhi Qing said. In the experimental area, the reporter saw a variety of water quality testing instruments such as multifunctional water quality analyzers, portable spectrophotometers, biotoxicity analyzers, portable dissolved oxygen analyzers, and emergency monitoring boxes. These instruments can be used for all cyanobacterial monitoring projects. Chaohu Water Quality Monitoring and Emergency Monitoring Requirements.

"Zhonghuanjian 1" entered the lake and soon it reached the Chaohu Gate and stopped at an intake of the Chaohu Water Plant. According to reports, this is a key area of ​​Chaohu water quality monitoring. After sampling the water, Fan Zhiqing and other staff immediately tested the water quality of different projects. “Chlorophyll a 5.47 μg/L, PH value 8.44, dissolved oxygen 9.95...” The monitor quickly obtained the results of various tests. Environmental monitoring station engineer Hu Zhengjun carefully recorded the results on a form. Hu Zhengjun told reporters that the test results showed that the water quality here was basically normal, but it was still necessary to continue testing at the next sampling point. Every day, the monitoring personnel are required to sample and test at several points in order to monitor the overall water quality of Chaohu Lake.

The sun is getting more and more blazing. “The hotter the days, the more busy we are in monitoring work. In the past, we took a sample of a small boat. One trip back and forth, the clothes were covered with a layer of salt; now, apart from sampling, sitting in a boat is not hot, and we can concentrate more on working. A monitoring officer told reporters.

“The warming of the two temperatures and the blowing of southeast winds are likely to cause blue-green algae outbreaks. We dare not take it lightly. With this emergency monitoring vessel, we can now monitor the water quality of the Chaohu Lake 24 hours a day and give a quick warning to the blue-green algae.” Chaohu City Tang Xiaoxian, head of the environmental monitoring station, told reporters.
