Buried the rural abandoned shells and reuse, and the university team "dots" solidarity into "gold"

In the summer vacation of this year, through the social practice activities of "Sanxiangxiang", Guangdong University students brought a number of provincial projects in the "Challenge Cup" to the fields and transformed the results of scientific and technological innovation into the effectiveness of rural revitalization. Innovation and entrepreneurial team. In 2020, the team's research project on abandoned shells won the silver award of the twelfth "Challenge Cup" Guangdong University Student Entrepreneurship Competition. This summer, the team continued to come to Tan Dou Town, Leizhou to carry out shell powder treatment technology publicity and promotion to make efforts to use the resource use of shells.

The reporter learned that shell powder is currently used in production coatings, water purifies, animal calcium supplements, soil acid -base regulators, vegetable and vegetable cleaning agents and other products. The team has promoted the establishment of the four linkage models of the government and research and research. The production of shell powder coating products has consumed more than 100 tons of abandoned shells, successfully driving more than 100 people employment, and achieving a per capita income of 2,000 yuan. "Point" rural waste into "gold". "In the next step, I hope to build a shell powder processing plant in local towns and villages to bring greater momentum to rural development." Said Li Yubin, the team instructor and director of the Chemical Experimental Teaching Center of Guangdong Ocean University.

"Shell Siege Village" pollutes the rural environment and investigate and explore the solution

In the coastal areas, the environmental pollution problem caused by shell solid waste has been in the past for a long time. Exploring the transformation of these solid waste into resources is a very worthy of exploring topics.

A few years ago, during a survey of environmental pollution and the theme of remediation, students of Guangdong Ocean University found that the abandoned shells were severely besieging the local villages. At that time, a product called "Shell Powder" had appeared on the market. This product has attracted widespread attention and also attracted the attention of the research team of Guangdong Ocean University.

However, after analyzing this new coating with students with students, the teacher of Guangdong Ocean University found that it was not very complete in terms of technical composition and use effects. As a result, the Guangdong Ocean University Shell Powder Application Innovation and Entrepreneurship Team started to start the research on the key technologies of shell powder -based environmentally friendly coatings.

In order to collect first -hand information for the research work and better understand the problem of abandoned shell pollution, in the summer vacation of 2019, the research team organized a research activity of college students' summer three -seated countryside, and walked into Tou Luo Village, Hehe Village, Tou Luo Village, Qin Dou Town, Leizhou City. Investigate the problem of abandoned shell treatment in the village and other places.

A team member recalled: "Some shells with a long stacking time have been weathered. When they step on it, they are broken and mixed with sand and stones on the ground. The annual output is as high as 200,000 tons, so 100,000 tons of abandoned shells will be generated each year. However, the abandoned shell cannot be recycled, nor can it be poured into the sea. It can only be stacked on the side of the road. Over time, the phenomenon of "shell siege village" is formed.

Local villagers also endure the stench emitted by the rotten rot from the residual snails on the shell. A young villager said to the players: "I really hope that one day I can get rid of the taste."

Such scenes make the research team move. Then, with the efforts of the team and the support of multiple parties, it lasted for 2 years. In the innovation and entrepreneurial team of the Guangdong Ocean University Shell Fan Fan Fans, the innovation and entrepreneurial team successfully developed an abandoned shell treatment technology, and proposed a new idea of ​​transforming abandoned shells to form a new type of shell powder coating. It also won the silver award of the 12th "Challenge Cup" Guangdong University Student Entrepreneurship Competition.

Exploring the possibility of building factories in local towns and villages, bringing greater kinetic energy to rural revitalization

After the twelfth "Challenge Cup" Guangdong University Student Entrepreneurship Competition, the team's research on shell powder treatment technology continued, and the research content also continued to expand from shell powder coatings. Li Yubin said that the team has developed a series of shell powder production technology. These production technologies can prepare shell powder of different specifications according to the needs of users, and can meet different needs from the particle size and purity. "As of now, we have developed four different shell powder production equipment, and five different functions of shell powder coatings have been developed."

While the research team promoted the iterative upgrade of shell powder treatment technology, the realistic results brought by technology have begun to appear slowly. With the support of schools and local governments, the team has built the "university -government -cooperative -enterprise" government -based research model.

Under this model, colleges and universities provide talents for the project transportation, government providing venue and policy support, and rural cooperatives provide free shells for the shell powder processing plant. The team provides technical support. The enterprise team is responsible for product promotion and sales. The four of the government and research and research are linking. At present, the production of shell powder coating products has accumulated more than 100 tons of abandoned shells, successfully driving more than 100 people to employment, and achieving a per capita income of 2,000 yuan.

In the summer vacation of this year, the research team once again came to the Tan Dou Town of Leizhou to carry out the summer social practice activities of the "Three Losses". The purpose of the team to continue to go to Qin Douzhen this year is very clear, that is, the possibility of exploring the local construction of shell powder processing plants.

Li Yubin said that although previously through the "college -government -cooperative -enterprise" government -based and research model, it has achieved some results in the resourceization of abandoned shells, but the processing of shell powder is based on the processing plant. "Shell powder production technology has been relatively improved. Now I hope to seek more support from the government and funds, explore the possibility of building a factory in the local village and towns, in order to truly solve the problem of 'Shell Siege Village' in Tan Dou Town, and empower the village revitalization. "

The reporter learned that in addition to coatings, shell powder can also be used in products such as production coatings, water purifies, animal calcium supplements, soil pH regulators, and vegetable and vegetable cleaning agents.In this regard, Li Yubin also said that the company that cooperated before was the company that produced shell powder coatings. In the future, it will try to cooperate with other companies to expand and enrich shell powder products.Text/Guangzhou Daily · Xinhuacheng Reporter: Deng Xiaoli Guangzhou Daily · Xinhuacheng Editor: Lin Jing
