Investigation on phenol leakage in Hangzhou exposed by water pollution incident

What did the Xin'an River water pollution incident expose? Hangzhou phenolleakage investigation. Because of the leakage accident of tank truck on expressway, the water quality of Xin'an River was polluted by phenol, which affected millions of people in downstream Hangzhou area safety. At present, the impact of this incident on the normal life of the masses is gradually disappearing. Some experts believe that under the background of frequent public environmental safety incidents, "Xin'anjiang Water Pollution Event" reflects the vulnerability of the public to panic, but also reflects that the emergency response capacity of local governments still needs to be improved, and even exposes the shortcomings of the prevention of dangerous goods transportation.

Hangzhou Phenol Leakage Caused Xin'anjiang Pollution

4:00 or so. A tank truck loaded with 31 tons of phenol chemicals broke down on the way from Shanghai Gaoqiao Chemical Plant to Longyou Hongyun Chemical Plant on the main road section of Xin'anjiang Expressway exit interchange via Hangzhou Xinjing Expressway. When the vehicle was in rush repair work, it broke down. During the operation, a heavy truck collided with it, resulting in tank rupture, phenol leakage, and the instant death of a rush repair worker. At the time of the accident, 20 tons of phenol leaked into the Xin'an River with surface water due to the influence of night and rainstorm, causing some water bodies to be polluted. Journalist saw on the scene on the 6th that the scene of trafficaccident had been basically cleaned up, and some phenol and contaminated soil remained in the scene had also been basically cleared. According to Lao Xinxiang, deputy director and spokesman of the Hangzhou Environmental Protection Bureau, five water plants in Tonglu and Fuyang counties and cities downstream of Hangzhou stopped taking water because Xin'anjiang, the site of the accident, was an important drinking water source upstream of Hangzhou. More than 550,000 residents'normal production and domestic water use was affected, and water use in the main urban area of Hangzhou was also seriously threatened.

The latest statistics show that, except for the point where the accident enters the river, the water quality of most of the polluted basins in Xin'an River has reached the standard. The water quality at the intake of Waterworks in the main urban area of Hangzhou and Fuyang, Binjiang, Xiaoshan and other places has reached the first-class water quality standard. Hangzhou people's living water is guaranteed to be safe, and most of the waterworks that stop taking water have already reached the standard. Restore water intake.

Lao Xinxiang said that environmental protection and sanitation departments continue to adhere to strict monitoring, pay close attention to the water quality monitoring points and the water quality changes at the intake and outlet of waterworks, and ensure that the on-site information is grasped and released at the first time. The results of water quality monitoring will be released to the public at the first time through the Hangzhou government website and related media.

Water pollution caused "water grabbing" to test the governing ability of the government. Hangzhou phenol leak polluted water caused Hangzhou residents to rush to buy bottled water on the 6th, and many large supermarkets sold out of bottled water on the same day. At present, the storm has subsided and supermarkets have resumed the normal supply of bottled water. Wahaha and Nongfu Shanquan officials said that the factory is starting at full capacity, which can guarantee the drinking water supply in Hangzhou. Experts believe that besides people's weak confidence in drinking water safety, the lack of phenol-related knowledge, the inadequate wording of some government emergency measures and announcements are also the causes of the rush to buy. The government's emergency response capacity also needs to be further enhanced. In the phenol leak incident, the local government clearly mentioned in the "Municipal Government's Notice on the Progress of Handling the Leakage Accident of Phenol Tank Truck on Hangxinjing Expressway in Jiande" and other government notices that "the general public should seize the opportunity to use various containers to store as much water as possible." At the press briefing, the relevant government departments also said that citizens "need not panic". In response, Yang Jianhua, deputy director of the Social Institute of Zhejiang Academy of Social Sciences, said that in emergencies, the government is the most important source of information for the public to understand the situation of the incident, and the "first impression" is particularly important. Therefore, the government should be cautious in using words in information dissemination and avoid adverse effects caused by improper use of words. At the same time, it is necessary to analyze the unfamiliar problems of the masses involved in the incident. Gu Zhenyu, General Secretary of the Party branch of the School of Environmental Science and Engineering, Zhejiang University of Industry and Commerce, said that phenol is a compound with benzene ring, insoluble in water, with little volatilization, and usually causes visceral lesions by causing protein denaturation. Twenty tons of phenol has been diluted by water and its concentration has been very low in Hangzhou. "When publishing information, the government must make it clear so as not to cause unnecessary panic." Gu Zhenyu said.

Tank truck leakage accidents frequently expose dangerous goods transport prevention board

Because of accidents of dangerous chemicals in the transport process, causing serious casualties and environmental pollution events, many times occur in China. On January 13, 2004, a leak accident of liquid chlorine tank truck occurred in Naocheng County, Henan Province, resulting in the emergency evacuation of more than 20,000 local people. On March 29, 2005, the extraordinary accident of liquid chlorine leakage in Huai'an section of Beijing-Shanghai Expressway resulted in 29 poisoning deaths and emergency evacuation of nearly 10,000 villagers. Song Xiaochun, deputy director of traffic administration bureau of Zhejiang Public Security Bureau, said that at present, China has strict regulations on the transportation of dangerous chemicals, but because of the characteristics of tanker truck transportation, the safety of transportation largely depends on "people". In such a phenol leak accident, the driver encountered a late night rainstorm in the course of transportation, and the visibility was extremely poor. In order to repair the vehicle failure, an obvious warning device must be set up to remind the passing vehicles. However, due to the neglect of drivers, the rear-end collision has resulted in serious consequences.
