Recently, Zhang Yuan, a teacher from Class 195 of Water Supply and Drainage Science and Engineering, School of Municipal Engineering, Qingdao University of Technology, was showing everyone his invention: “This is a submersible for aquariums. The immobilized nitrifying bacteria water treatment device mainly fixes the nitrifying bacteria on the suspended biological carrier. With the operation of the device, the water quality in the aquarium is purified, which can solve the problems caused by frequent water changes in the aquarium. ”
Talking about the background of this invention, Zhang Yuan introduced: “I have a large fish tank at home, and the water needs to be changed every week. Most of the water in the tank must be poured out at one time, which is troublesome and wasteful. I just wanted to use my professional knowledge to solve the problem of frequent water changes in aquariums. With the help of teachers and senior students, I completed the construction of this device.” After the device was built, Zhang Yuan first ran it in his own fish tank. , half a year has passed, Zhang Yuan’s fish are jumping around happily, and the water in the fish tank has not been changed. I went to the laboratory ET Escorts to test the water quality in the fish tank, and it was indeed tested. Less than ammonia nitrogen and nitrite nitrogen. The test was successful and the assembly passed.
With the help of tutors, the surrounding environment and the School of Municipal Engineering established a “Diewu Water Treatment Team” composed mainly of postgraduates and undergraduates specializing in water supply and drainage. They have a thorough understanding of the working principles and assembly optimization. The team went to local aquariums and the homes of fish-keeping enthusiasts to understand the current situation of the aquariums through visits, discussions, etc., and conducted working principle experiments and installation experiments with the help of instructors, optimizing water treatment methods and the internal structure of the installation, so that the installation has a simple structure. , stable performance, low manufacturing cost, good application effect and strong applicability.
Bi Xuejun, team leader and professor at the School of Environmental and Municipal Engineering, said: “The team members innovatively proposed the aquarium water purification device, which is novel in both conception and design. It is feasible and practical to give birth to children in batches. By participating in such innovative implementation activities, students have effectively improved their ability to analyze and solve problems.” While assisting the team and conducting scientific research leadership, Bi Xuejun contacted many parties. Contact enterprises and assist the team in completing patent transformation, thereby stimulating students’ motivation for learning and scientific research.
The team completed more than 10 assemblies in the laboratory and made these Ethiopia Sugar DaddyThe device was distributed free of charge to residents who raise fish and to aquarium shops for trial use, and received excellent feedback from many usersEthiopia Sugar Daddy responded. Currently, the team has applied for 1 invention patent, 1 authorized national applicable new patent, and 1 design patent.
“Scientific research is the best lecture hall. “Take scientific research, competitions, etc. as the second classroom, encourage students to introduce Ethiopia Sugar Daddy, and “force” students to pass the first class The classroom supplements and strengthens practical learning, and students become more enthusiastic as they learn. Bi Xuejun said that in the traditional lecture mode, students often “complain” about the internal business mechanics of learning. Even if they understand it in class, they do not understand it after class. How to use it. In order to prevent students from using “two skins”, the School of Environmental and Municipal Engineering will “move” scientific research competitions and patent inventions that reflect students’ disciplinary abilities to the classroom to connect professional research and industry to achieve “same frequency” Resonance”.
Ma Li, Secretary of the Party Committee of Qingdao University of Science and Technology School of Municipal Engineering, said: “It is necessary to cultivate high-quality new engineering talents with high tools that meet the needs of the country and society. , relying solely on book knowledge and classroom teaching is far from enough. The surrounding environment and the School of Municipal Engineering carry out teaching model reform through exploration, with the integration of industry and education as the main line, combining theory and practice, relying on the training base platform, ET Escorts attaches great importance to the transformation of learning results, applies specialized knowledge and skills in life, and gradually embarks on a path of teaching and transformation with distinctive characteristics, allowing students to run on a more colorful development track. Make good achievements. ” (China Education News-China Education News Network reporter Sun Jun)
