C315 Disinfection Learning Class

This disinfection training class is actually quite important to Qin Wen and the others.

However, because Pei Xiaoxiao was worried that they would have to do the same work after class, the number of missions did not decrease at all. She was afraid that Qin Wen and Liu would only agree to help her verbally, but in reality, they would not help her. Therefore, she did not fully listen to this class.

However, she heard the lecturer speaking frankly and confidently on the podium,. . . "It's a very critical period now. The disinfection work is indispensable. There are a few points that are very important. Everyone must remember this. The first was to choose the appropriate disinfectant. Before disinfection, you can choose drugs that are strong in killing the pathogen, have a long duration of disinfection, and are less toxic to humans and animals. The disinfectant should have the advantages of not damaging objects and machines, being easy to dissolve in water, being cheap, convenient to use, and so on. However, it is very difficult to choose a disinfectant that completely meets these conditions in actual work. You can only choose the appropriate disinfectant based on the local situation. "

" The second point is to pay attention to the factors that affect the disinfection effect. What about me? There are roughly a few types. You have to listen carefully. First, the hygiene of the disinfection environment affects the disinfection effect. If the sterilized animal house is disinfected. . . First, it had to be thoroughly cleaned, washed, and removed from the feces and other organic pollutants. The roof of the animal house had to be cleaned as well. We need to remove the dust and spider webs. Otherwise, it will affect the disinfection effect. . . "

When he spoke of this, the employees below began to whisper to each other, because they were not involved in this. The environmental disinfection was because they were just people who worked. In terms of these things, the scope was really too wide.

"This teacher charged according to class hours. He probably wanted to fill up the class hours, so he added some content. " A person wearing glasses said. Everyone burst into laughter. When the teacher heard this, his expression became extremely ugly. However, these were all important contents in his own teaching plans. How could he not tell them?

"I know that everyone might not want to hear about these disinfectant things, but. . . There are some departments that are indeed related to livestock and birds. These things must be especially sterilized. For example, you raise pets in your own home. Don't you need to listen to these content? When sterilizing livestock, you must use a disinfectant that is less stimulating to humans and animals and has low toxicity. The spray nozzle sprays out fog particles, the diameter of the fog should be controlled at 80 ~ 120 meters. It could not directly spray mist and disinfect the head of the poultry to prevent damage to the eyes of the poultry. The disinfecting of poultry can be carried out once every 3 ~ 5 days according to the specific situation. . . "

The lecturer tirelessly explained on the stage and even drew a picture. Everyone kept yawning as they listened, but Qin Wen suddenly felt that it would be great if these were used in the Qin Village. Unfortunately, this teacher didn't come to the Qin Village to give a lecture. She turned on the audio key on her phone. She felt that this information should be usable by her father and the others. Then, she used the notebook to record the pictures of her teacher's lecture.

When the lecturer saw such a mystical student below, he felt that he had achieved something. Unfortunately, there was only one such student.

"Thirdly, the concentration of disinfectant used is proportionate to the disinfection effect. It must be used according to the specified concentration. Otherwise, it will affect the disinfection effect. Also, the temperature of the drugs and the disinfection effect are also proportionate. For example, the disinfection effect of the hot alkali water was better. When using formalin to heat and sterilize, the doors and windows must be closed when there were no livestock. Sealed the gaps and continued to evaporate for 8 to 10 hours without affecting the group transfer. Then open the doors and windows to discharge the remaining drug gas before transferring it to the livestock. . . "

An employee was listening to the lecture below when he suddenly fell asleep on the table. The lecturer angrily walked over and knocked on the table. He woke up. But looking at the angry expression of the lecturer, he was unwilling.

He was a young and aggressive employee. He originally felt that he did not want to do this job much and might resign at any time. Someone had actually given him a slap in the face. He was even more unhappy.

The lecturer asked him why he didn't listen properly.

He smiled brightly and asked loudly: "This teacher always talks about livestock and birds. You can't be a veterinarian, right?"

When everyone heard the word veterinarian, some agreed and smiled knowingly. Later on, the atmosphere became worse and worse. Qin Wen felt that everyone had gone too far. Although this lecturer's lectures were a bit redundant, these things were actually used in some households in the city, especially in raising pets, and were more practical.

"Aiya, it's really annoying. How can this noisy class be like this?"

Pei Xiaoxiao simply put on her earphones. Then, she spread her shoulder-length hair so that others could not see. When she started to listen to music, Liu also imitated her by the side.

However, Qin Wen had been holding it in until she drew the diagrams on the blackboard onto her notebook.

The lecturer walked over and took off Xiao Liu's earpiece.

He said angrily, "Don't think I'm afraid of you. Although you guys are now in society, since you're in this classroom, you can be considered my students. Your performance, I'm here to give you points. Didn't you see your names on the seats? Don't I know who you are? "

The person who spoke earlier simply said arrogantly," At most, I'll just remember it. Anyway, we're not students now. We'll just remember it, and the factory won't deduct money from us. They're all people from the various workshops in society, so how could they have the time to listen to poultry lessons? Teacher, can't you tell us about other disinfectants?"

The teacher seemed to be very sad when he saw everyone's expressions. He walked to the podium and picked up the lesson plans that he had carefully prepared. Then, just as he was about to call out names, he suddenly realized that the name list in his notebook was not the same as the name list in the classroom.

"Aren't you from Class 606? Today, I am here to give a lecture on poultry and antidotes, I am the main speaker. "

"What Class 606? We're in class 909. " The student took the lead and jeered. He said that the teacher must have walked into the wrong room.

The teacher angrily walked to the door and pointed at the sign on it. "It's clearly Class 606, why do you say it's 909?"

The student simply got down from his seat and walked to the door. He looked up and suddenly, his expression was a little bad. Just now, he had played a slingshot game with a few classmates out of boredom and had used this sign. He did not expect that the sign would be crooked. Then, someone kindly fixed the card. It became 606.

"So it was my fault. I'm sorry, teacher. " He immediately apologized to his teacher.

However, because the teacher was not in the class, they thought that the teacher had taken a leave of absence. Thus, the class became empty.
