Turning waste into treasure has made green the most vivid background of high -quality development. This practice is staged in Xiaoshimura, Boluo County, Huizhou City, Guangdong Province.

The solid waste and wastewater generated by gemstones process, after the resource use, the wastewater is fully used in production to achieve the wastewater discharge; the solid waste becomes a high value -added resource -based product, and the new technological achievements of environmental protection will be transformed. Gem processing enterprises continue to green development ... It was a "frequent" small Jincun on the blacklist on the blacklist of environmental protection. With the help of the special agent of technology in Guangdong Province, it not only gradually solved the pain points and difficulties in the development of the gem processing industry, but also developed the "city city The concept of mine is the concept of clean production and green civilization.

"Through the gem industry intensive production, transformation and upgrading, the use of environmental protection technology to promote the green development of gemstones, drive the local economic transformation and upgrading, and promote rural revitalization." Professor Yu Lianxiang said.

Today, in Xiaojin Village, the villagers have a thumbs up.

Once being trapped in environmental protection "blacklist"

When it comes to the gem processing industry, the villagers in Xiaojin Village love and hate. Xiaojin Village is located in the northern part of the Greater Bay Area, and has developed the gem processing industry since the beginning of the reform and opening up. With its unique processing and manufacturing capabilities, after more than 30 years of accumulation, many famous teachers have gathered, forming a industrial chain from processing from open stone, blank, pre -shape, etc. to the sales of one -stop, and the products are exported to domestic and foreign. During the heyday, there were more than 5,000 small workshops, with a population of more than 50,000 people. The total output value of the gem processing industry exceeds 6 billion yuan, which is one of the local pillar industries.

However, the heart hurts villagers is that the life of the red fire is at the expense of the environment. Local villagers recalled that the processing methods of "small workshops" were low -end and backward. The mud waste and wastewater generated were directly poured into a nearby small river or ground to evaporate and dried. The wastewater of the pollutants is then penetrated into the soil and farmland ... Xiaogin Village was once deeply trapped in the "blacklist" of environmental protection.

The green mountains and green mountains are Jinshan Yinshan. How to achieve industrial transformation and green sustainable development while ensuring the stable development of the local economy has become an urgent problem that Xiaosjun Village needs to solve.

"When I first arrived in Xiaojin Village, I was taken aback, scattered, chaotic, and dirty. The whole environment was particularly bad." In 2017, Yu Lianxiang, a special agent of technology in Guangdong Province, came to Xiaojin Village. She and the team began to investigate Small Jincun Four Corporal Gem Processing Small Workshop Small Waste Waste and Waste Water Generation and Management.

Based on a large number of investigations, Yu Lianxiang and the team carried out "the feasibility test of gem processing fixed waste and wastewater resources". The following year, they developed the first domestic technical achievements of solid waste and wastewater in the gem processing industry -the full -value utilization technology of gem processing corners and mud wastewater. Industrial transformation and upgrading provides technology.

"The technology of solid waste and wastewater resource resources can not only completely solve the serious environmental problems in the gem processing industry for more than 20 years, improve the circular economy level of the gem processing industry, and promote the transformation and upgrading of the local jewelry industry, and the green sustainable development; at the same time It can also create a good environment for the division of labor and cooperation, cooperative development of upstream and downstream enterprises, and the development of brand building and professional market development. "Yu Lianxiang said. Relying on scientific and technological power, Xiaojin Village has embarked on the road of green development.

New technologies realize the full value of solid waste

Xiaojin Village companies that tasted sweets came to the door. Among them, Shenzhen Shenguang Investment Development Group Co., Ltd. (hereinafter referred to as Shen Guangyi) signed a 10 -year scientific research and development framework cooperation agreement with the rare earth of resources. Since then, Shen Guangyi has been approved to bear the construction and management of the four -corner building jewelry creative industrial park (hereinafter referred to as the four -corner building jewelry park). middle.

In April 2020, Huizhou Shenglei Environmental Protection Technology Development Co., Ltd. (hereinafter referred to as Sheng Lei Environmental Protection) released technical needs through the implementation of the "Huajuan.com" through the Guangdong Enterprise Science and Technology Special Commissioner, hoping to solve the problem through the power of scientific research institutions and scientific research experts to solve the problem Local environmental protection issues. Through the intelligent matching of "Huajuan.com", Sheng Lei has successfully connected Yu Lianxiang.

In response to the same environmental needs of many enterprises such as Shen Guangyu and Sheng Lei, Yu Lianxiang introduced the concept of "urban mine", combining mineral processing methods with environmental protection concepts and means, and developed the use of solid waste and wastewater resources produced by gem processing. new technology. In April 2021, the technology achieved results transformation in the jewelry garden of the four -corner building. With the help of Yu Lianxiang's guidance, the four -corner tower jewelry garden realizes the classification of gem processing and solid waste, and wastewater is concentrated in the environmental protection center for treatment. Institutions carry out basic research and promotion research on industrial wastewater and solid waste resources, accelerate the clean production of the jewelry industry, promote the industrial innovation and achievements of the jewelry garden of the four corners, and open the new development model of the four -corner jewelry garden circulation industry Essence

"Thanks to the hard work of the technology agent, we can finally sleep well." When we see the milk -colored wastewater from the four -corner jewelry garden to the environmental protection center At the time of production, the gem processing households in the park rushed happily. Last year, Yu Lianxiang led the team to adhere to the debugging of the mud wastewater production line of the four -corner jewelry garden environmental protection center. According to her, the production line has currently served 99 enterprises in the park, which solves the environmental pollution problem of long -term trouble in the jewelry processing industry of the four -corner building. Essence

"We have created the first domestic gem processing solid waste and wastewater resources to use the demonstration base of industry -university and research through scientific and technological innovation to realize the orderly agglomeration of the industry and solve the problem of pollution of gem processing. Utilized, truly realized the transformation and upgrading of the gem processing industry and green development. "Yu Lianxiang said.

Lead the transformation and upgrading of gem processing industry

In May 2021, the Huizhou R & D Center (hereinafter referred to as the R & D Center) of the Rare Earth Institute was officially established at the Four -Corporal Jewelry Garden. The R & D Center was jointly established by the Resource Rare Earth Institute and many Huizhou companies to provide technical support for the gem processing industry for a long time.

"The R & D center can not only solve the problem of gem processing environment in the current four -corner building area, but also promote the new technologies we developed to about 30 gem processing splits across the country, leading the transformation and upgrading of gem processing industrial clusters to achieve green development." Yu Lianxiang introduced.

"Turbid water turns clear", "gemstone glow" ... a small test made visitors shout. The R & D center not only brings technology, but also builds the cultural science popularization education base of Baoyu Industrial, introducing the results of solid waste, wastewater resources, and the characteristics of high -value use of environmental protection products such as mineral pigments and artificial quartz stones. Contribute the power of its own efforts for the continuous and stable development of the jewelry processing industry.

From a science and technology agent settled in an enterprise to the establishment of the R & D center, we brought a scientific research force for the local area. Transcript.

"In the next step, we will combine the strength of scientific research institutes in the relevant fields of Guangdong Academy of Sciences to give play to professional talents and good test conditions advantages, and innovate in the development of mineral material products, high -value use of tail materials, and intelligent intelligent manufacturing. , Realize the automation, intelligence and standardization of industrial development, enhance the influence of gem brand, and expand the market. "Yu Lianxiang said.

The experience of many years of science and technology agents has allowed Yu Lianxiang to deeply understand that in the absence of corporate technical power, the role of science and technology specialists can be fully played, and it can quickly supplement the innovation for enterprises. She said: "The market -oriented, joint innovation of enterprises, universities, and research institutes is an effective way to enhance corporate innovation capabilities, promote the transformation and upgrading of gem processing industries, and accelerate intelligent environmental protection development."
