From October 12th to 15th, 2019, the final of the 5th China College Students'   “Internet Plus” Innovation and Entrepreneurship Competition was held in   Zhejiang University. Liu Wei，a   junior graduate at USST，and   his team won the bronze prize for their project on the water quality guard of unattended water body based on microbial media.

Nowadays,   the overproduction caused by rapid economic development and urbanization is   the most serious problem that hits rivers and lakes in China. Excessive   artificial rivers and lakes are one of the greatest problems that threaten   the water ecological environment. Due to the closed and non-flowing nature of   the water body, the self-purification capacity of the water body is seriously   degraded, which directly leads to the loss of ecological functions and the   collapse of the ecosystem in the water zone. With the original intention of   environmentally friendly and resources-saving water spatial pattern, Liu Wei   and his team engaged in the project. The team's self-developed   high-efficiency aeration equipment and systems can rapidly increase the   dissolved oxygen content of water bodies, which is two to three times that of   conventional water tankers or impellers. As a result, the dissolved oxygen of   the water body is rapidly increased, and the problem of black odor can be   solved within three to five days. Depending on the water quality, the product   can automatically control the flow rate of the water stream, thereby   inhibiting the growth rate of algae and preventing algae blooms. 

At   present, this product has been vigorously promoted by Shanghai Municipal   Government, Shanghai Education Commission, the Pinghu Agricultural Bureau and   Wujiang Water Authority, Suzhou. Customers include large state-owned   enterprises like China Railway, China Construction and some corporations like   Guozhen Environmental Protection, Yonker Environmental Protection (HK）. They   also established extensive cooperative relations with other environmental   protection companies in Jiangsu, Zhejiang and Shanghai.

However,   the achievement has not come easily. It is difficult for Liu Wei to set about   entrepreneurship practice that he had not done before. In the beginning, he   did not know how to make a start, and thus he actively participated in   various entrepreneurship competitions, listened to the different ideas of the   contest judges and quickly absorbed the relevant knowledge of   entrepreneurship field. Meanwhile, as a science student, Liu Wei had the   biggest difficulty in the competition in writing a business plan and making a   live demonstration of his product. He has the technological knowledge, but   not in finance, material layout and other aspects. Therefore, he widely   attracts students from different schools such as College of Communication and   Art Design, Business School to join in his team. Fortunately, with the help   of team members along the way, they helped each other overcome many   difficulties.

When   it came to the feeling of winning the prize, he felt excited and grateful. “I   was very lucky to meet my team partners. Our sweat and all-nighter efforts   reach the achievements,” said Liu Wei. He thanked every advisor for their   careful guidance and every team member for their dedication. He hoped this   practice could become a warm memory for them all. What’s more, Liu Wei was   very happy to have gained a lot. “Internet +” competition enlightened himself   to try to start his own business. He has learned how to write a business   plan, how to present his project to the audience in a most effective way. At   the same time, he constantly enriched his theoretical knowledge in the   practice.
