Northeast Network June 4 news Recently, the "small worm" in the homes of the residents of Weimei Main Yi, Xiangyi Mingyuan and the residents of the community connected to their water supply pipelines has appeared, which has aroused the close attention of the residents of the community and the general public. So where do these bugs in tap water come from? What bugs are they? Is it harmful to the human body? With these questions in mind, the reporter conducted an interview.
On the afternoon of June 3, the reporter came to the Weimei Main Yi Community, the staff of the Municipal Water Affairs Group is disinfecting the water pipeline here, according to the staff, they are in accordance with the national regulations to inject water treatment disinfectant - chlorine dioxide. At present, the water pipelines in the affected communities are being disinfected and flushed at the same time.
Where do the "white worms" in the water come from? Leng Yunlin, director of the Water Supply and Drainage Management Center of the Municipal Water Affairs Bureau, introduced that there are many kinds of factors that appear "small insects", this time the experts preliminarily determined that the water supply pipelines and related fire fighting facilities in the community are insufficient in the design and operation management process, especially the indoor and outdoor fire fighting facilities in the community are directly connected to the domestic water supply pipe network, these fire fighting facilities such as: fire branch lines are too long underground fire hydrants, do not need to form "stagnant water" all year round, it is easy to breed bacteria, and become a "small insect" parasitic environment. When the pressure of the domestic water supply network fluctuates, the "stagnant water" in the fire protection system returns, causing the water quality of the water supply system in the community to change. Such phenomena also occur from time to time in other parts of the country.
After the incident, the Municipal Water Affairs Bureau entrusted the Daqing Monitoring Station of the National Water Quality Monitoring Network to sample and test the factory water of dongcheng water plant, and the test results showed that it met the national drinking water sanitation standards. At the same time, experts from inside and outside the province were invited to form an expert group to conduct on-site inspections of the affected communities and to sample and analyze the drinking water of residents. Through consultation with Zhu Lin, a top domestic expert who has conducted systematic research on "small worms" and a well-known professor at Nankai University, the identification results obtained are: the "small worms" that appear in tap water are the larvae of water worms, which do not belong to human parasites, and stomach acid and high temperature can quickly kill them, whether they are alive or dead. Water present with the worm did not exhibit toxic effects and had no effect on the safety of water quality.
As of press time, the relevant departments have cut off the connection point between the fire fighting facilities and the water supply pipeline set up in violation of the law, and according to expert opinions, the amount of water treatment agents in the factory has been increased in accordance with national standards, and the water discharge fees in the homes of users in the community have been reduced or reduced. At present, the number of "small worms" in the tap water of Weimei Main Yi and Xiangyi Mingyuan Community has been effectively controlled and shown a downward trend. Shi Xiaodong, general manager of the Municipal Water Affairs Group Co., Ltd., said that the Municipal Water Affairs Group is paying close attention to and monitoring the water quality of the water supply pipe network in the community, increasing the disinfection of the secondary water supply link, and hoping that the residents of the community will continue to do a good job in their own drainage work and cooperate with relevant departments to jointly solve this problem. The next step will also be to conduct a comprehensive inspection of all facilities in the area under responsibility, and clean up other facilities that are privately connected to the domestic water supply pipeline to ensure the safety of water supply.
The water supply department reminds residents to regularly clean their solar water heaters, faucet filters, water purification equipment, etc., develop good water use habits, and avoid "terminal" water pollution to prevent "small insects" from breeding and breeding.
