Exposure of Air Odor in Paper Mill of Binhai Middle School in Haiyan County, Jiaxing

At 8: 46 that night, Haiyan Environmental Protection Bureau released a message through Guan Wei:

The odor emission concentration at the boundary of Ji 'an West Factory sampled and monitored this afternoon was 53.6, which did not meet the standard requirements in the Discharge Standard for Odor Pollutants (GB 14554-93) table 1(≤20). The odor emission concentration in front of the teaching building of Binhai Middle School is 24.7. After investigation, we determined that the source of odor pollution was Ji 'an Group. At present, the largest production line No.3 of this enterprise has been discontinued, and our bureau will initiate an investigation on this enterprise.

However, Ji 'an Group is separated from Binhai Middle School by a wall.

At the flag-raising ceremony, five students suddenly felt uncomfortable.

At 4 pm on the 28th, my colleagues and I arrived at Binhai Middle School. As soon as I opened the car door, a pungent smell came straight at me, which made people feel chest tightness.

The school is located in the northwest corner of Haiyan County, close to the north bank of Hangzhou Bay Bridge. In June 2008, 165438+ 10, it was formed by the merger of the former Haitang Middle School and Xitang Middle School. The new campus covers an area of 60 mu and is the largest rural junior middle school in the area. At present, there are 1 19 in-service teachers and * * * students in 36 classes 1 195.

At 9 am on the 28th, the students had just finished two big classes. On Monday, the flag raising ceremony will be held at 9: 05. During this period, five students experienced chest tightness and vomiting.

"We immediately sent the students back to the classroom to rest. Four people from Class 9, Grade 7 just finished physical education class. One of them may not have breakfast and his blood sugar is low. "

Principal Song said that when students returned to school at 7 o'clock in the morning, the smell in the air was already obvious, but the unexpected situation exceeded the school's expectations. After that, the school immediately stopped all outdoor classes, the classroom began to close the windows, and at the same time reported to the higher authorities.

At about 9: 30, Guo, a member of the Party Working Committee of Haiyan Economic Development Zone, drove by the school and smelled a rather strong smell.

15 minutes later, a school teacher posted three photos on Weibo, calling for social attention. Through the fermentation of social media, Song said that some parents rushed to school to send masks.

Embarrassed schools are located downwind of chemical plants and paper mills.

Song has been teaching in the local area for 10 years, and he said that the bad smell in the air is a common occurrence. Seven years after moving into the new campus, all kinds of unpleasant smells have harassed the lives of teachers and students.

"There will be when the weather is bad, just like today's low pressure." He said that the daily smells are mainly sour, chemical and even seafood. Last time, some students had obvious discomfort, and it dates back to the second half of 20 14.

Teacher Huang, in the eighth grade, told me that the smell never stopped from the first day I moved into the new campus. The most important thing is the fermented smell of carton plant, followed by the smell of chemical plant and pesticide plant, and sometimes there is sewage smell. Many young teachers in his office are allergic to skin: "We have a female teacher who is pregnant and has been unwell since she smelled bad smell last week. She has asked for leave this week. "

What worries him even more is that some students cover their mouths and noses in class and have to suggest that children simply wear masks. He felt sorry for the students to cancel the outdoor skipping during recess.

Odor has become a daily phenomenon, which is not unrelated to the embarrassing geographical location of Binhai Middle School. Guo drew a schematic diagram for me: the school is located in the commercial and residential area of the development zone, about 8 kilometers east of Jiaxing Port where a large number of chemical enterprises gather, about 2.5 kilometers south of Lingang Industrial Zone adjacent to Qiantang River, and about 3 kilometers southeast of Jiaxing City, which is the largest combined sewage treatment plant.

Due to the southeast wind on weekdays, Binhai Middle School is located in the downwind, and the airflow brings the above odor. Song said that the air quality in schools depends on the sky and wind direction.

The nearest industrial enterprise to Binhai Middle School belongs to Ji 'an Group, separated by a wall. This is a paper-making enterprise established in May 2004, which belongs to shanying paper, and its annual paper-making capacity is about 6.5438+0.35 million tons. It has been successively rated as "Environmental Friendly Enterprise in China Paper Industry" and "Top Ten Private Enterprises in Jiaxing City", and it is also one of the "largest industrial backbone enterprises and top ten taxpayers" in Haiyan County.

Although great efforts have been made to upgrade environmental protection equipment, local residents said that the stench can still be smelled outside the factory.

/kloc-who will protect the health of more than 300 teachers and students?

At 6 o'clock in the evening, I walked from the school gate to the playground, and there was a faint smell on the 200-meter road. The school playground is 300 meters long, not far from the cross-sea bridge, and the southeast side is the road, which is extremely empty. The highest shelter may be Metasequoia glyptostroboides on the roadside, and the wind is blowing wantonly.

The accompanying teacher told me that the playground and the student dormitory next to it were the first to suffer when the southeast wind blew. Xiao Wu, in Class Two, Grade Eight, is one of 200 students who live on campus. He said, "Sometimes you can smell a pungent smell when you wake up in the morning."

Xiao Peng, 12 years old, has been studying in Xitang Street since the fourth grade of primary school. The little girl said that she usually smells like tea eggs, and some students in the class are worried.

Xiaohong, a PE teacher, has been in school for two years. Although he is in good health, he still suffers from severe rhinitis: "Since I came here, I have smelled too many smells, and now I can't distinguish some of them."

A teacher who did not want to be named played a joke on me. He said, like today's smell, the students who just entered the seventh grade may have a big reaction, and the students in the ninth grade may be used to it and can't smell it: "Now these children are in the development stage, and the cardiopulmonary function can't be affected."

Due to the changeable weather, the school did not buy air processors and other equipment, so students and teachers can only take preventive measures by bringing their own masks.

Zhu, deputy director of Haiyan County Environmental Protection Bureau, revealed that Ji 'an Group's daily monitoring of water pollution and thermoelectric emissions is carried out in accordance with the standards of state-controlled enterprises. The odor on the 28th mainly appeared in sewage tank treatment, waste paper raw material storage and workshop drying.
