Colorful Guizhou Network News (Reporter Li Sijin) "The sprinkler truck is also operating on rainy days, is it necessary?" On September 23, it was raining lightly in Guiyang. When Mr. Li, a citizen passing by Shibei Road, saw a license plate of "Gui A49XX" His sprinkler was sprinkling water, and it stopped slowly or there was still water spilling out when waiting for the red light, he was puzzled.

  "The operation of sprinklers on rainy days is not superfluous." Yu Pingsong, assistant general manager of Guiyang Jingzhu Company responsible for environmental sanitation in Yunyan District, said in an interview with reporters that when it is sunny, sprinklers are activated in dust reduction mode; on rainy days, sprays It is powerful high-pressure water, which can wash garbage and fallen leaves on the road to both sides of the road.

  Yu Pingsong explained that such scouring is more conducive to road cleaning. "Especially this season, the main roads of Yunyan District, Baoshan North Road, Beijing Road, Shibei Road, and other roads are constantly falling leaves. When it rains, the leaves are wet. It’s close to the ground and it’s hard to clean."

  "After the sprinklers are washed along the way, there will be a suction sweeper to follow up to suck away the fragmented garbage that has been washed on both sides of the road. The two vehicles work in tandem, which not only makes the road cleaner, but also reduces The workload of sanitation workers." Yu Pingsong said.

  In addition, with the continuous advancement of urban construction, some trucks inevitably throw out fine debris when carrying building materials such as stones and yellow sand. The mud on the wheels entering and leaving the construction site also pollutes the road. Once it rains, they will be soaked in rainwater. Efforts to land sharply, this is the best time for sprinkler and suction sweeper operations.

  As for citizen Mr. Li seeing the sprinklers stop slowly or the water overflows while waiting for the red light, Yu Pingsong explained: “The citizens should see the remaining water in the spray channel. Because the water tank of the sprinkler is at a speed of 20 It will be closed automatically below the code."

  Some citizens questioned whether the sprinklers would wash the litter onto the sidewalks if they were driven on the sidewalk in rainy days. If sanitation workers did not clean them in time, would it affect the citizens to walk.

  Yu Pingsong responded that in the rainy day operation mode of the sprinkler, the water sprayed parallel to the ground will be blocked by the road teeth.

"If part of it is rushed to the sidewalk, sanitation workers will help clean it, but this is rare."

  Aunt Wang, a sanitation worker on Wenchang Road, also confirmed this statement. She has been in cleaning for 7 years. She said that after having sprinklers and suction sweepers for machine cleaning, only occasional cleaning is needed near the road teeth.

  Mr. Zhou, a taxi driver in Guiyang City, talked to reporters. One time he ran the night shift and encountered heavy rain. He even saw sprinklers working on the road.

  Yu Pingsong responded that if there is a heavy rain, more branches and leaves will be knocked down. Sprinklers and suction sweepers operate at this time to prevent the sewer entrance from being blocked.

  Yu Pingsong said that in order to save water resources, Guiyang Jingzhu Company is also doing some explorations. At present, Guizhou Medical University Affiliated Hospital and Liuguangmen Sewage Treatment Plant have reached an agreement. After one or two months, the water trucks in Yunyan District will be tested. The "intermediate water" treated in the sewage plant can be reused.

  Mr. Wang, who lives in Huaguoyuan, also has some small opinions on sprinklers.

He once encountered sprinklers working during rush hours, and on one occasion he missed the check-in time at work, but recently, he rarely encountered sprinklers on the way to and from get off work.

  "Some citizens approached us before and talked about this kind of situation." Yu Pingsong said that the working hours of the sprinklers and sweepers are divided into two shifts, one is from 9 am to 5 pm, and the other is from 11 pm to the first. At 6 o'clock in the morning of the next day, "Our company has put forward requirements for the staff, requiring the sprinklers that work in day shifts to start work after the morning peak as much as possible, and complete the work before the evening peak, so as not to increase congestion."

  Reclaimed water: also known as "reclaimed water", refers to water that can be beneficially used after wastewater or rainwater has been properly treated to meet certain water quality indicators and meet certain usage requirements.

Compared with seawater desalination and cross-basin water transfer, reclaimed water has obvious advantages.

From an economic point of view, the cost of reclaimed water is the lowest. From an environmental point of view, sewage recycling can help improve the ecological environment and realize a virtuous cycle of water ecology.
