Confirm whether tap water is groundwater.

Since the beginning of summer, the water level in Xijiang River has skyrocketed, and garbage floats on the river from time to time, making the river turbid. Some citizens are worried about the health and safety of drinking water, so they call our newspaper and Zhaoqing Water Group for consultation. On July 2, the reporter interviewed the relevant person in charge of the group on this matter. The turbidity of the river does not affect the water quality.

According to Du, the stationmaster and senior engineer of Zhaoqing Monitoring Station of Zhaoqing Water Group, there are five types of drinking surface water at present, one is the source water without any pollution; The second kind of water is basically a pollution-free water source; Although three kinds of water are polluted, they can still be used as drinking water sources; Four or five kinds of water pollution are serious and cannot be used as drinking water sources.

Du said: "The water source of Zhaoqing City is Xijiang River. Although the water level in Xijiang River has skyrocketed some time ago, garbage floats on the water surface and the river is turbid. However, the flow of Xijiang River is second only to that of Yangtze River, and its self-purification ability is strong. Therefore, the water quality of Zhaoqing section of Xijiang River is kept within the second-class water standard all the year round, and it is a rare drinking water source with sufficient water and excellent water quality in China. " Layers of checkpoints ensure water quality

In the afternoon, the reporter went to Sanrong Waterworks and Zhaoqing Water Quality Monitoring Station of Zhaoqing Water Group to learn about the production and water supply process of Zhaoqing tap water. The reporter saw that the water intake pumping station of Zhaoqing tap water is located at the mouth of Sanrong Gorge in Xijiang River, where the water flows rapidly and there is no garbage and sediment at the water intake.

Xijiang water is pumped into the rotating and grid reaction tank by the pumping station, and then the purifying agent is added. After rotating, the suspended matter becomes the bottom of the large particle sedimentation tank. The river begins to clear and then flows to the V-shaped filter. According to reports, quartz sand is added to the V-type filter, and the river water is clear after being filtered here. "Then add liquid chlorine and other disinfectants and fungicides that are harmless to the human body. After the river flows from the V-shaped filter into the clear water pool, we will test the water quality and then send it to the water supply pipeline under pressure. "

After tap water enters the water supply pipeline, the monitoring station is still closely monitoring the water quality. Du told reporters: "We have set up 20 monitoring points in the urban area, sampling and monitoring the water quality every day, and comprehensively analyzing and testing 1 15 items such as source water, factory water and pipe network water every month. In addition, the municipal centers for disease control and prevention, health supervision and other management departments also regularly test and supervise tap water. Therefore, residents can drink with confidence. " The above is a piece of news, you will know after reading it, I hope to adopt it! ! ! ! ! !
