On October 23, 2025, Sun Hualin, the president of Tianjin Environmental Protection Industry Association, Ma Hongbing, the Party secretary of Jilin Environmental Protection Industry Association, along with leaders from environmental protection industry associations in Hebei Province, Shanxi Province, Henan Province and other places, joined forces with industry professionals such as Qian Pingping, the chairman of Global Group, Chen Zhi 'an, the founder of Huanxiao Er Industry Service Platform, and Kong Weimin of Yixing Environmental Protection Association. Jointly went to Lingzhi Equipment Group for research and exchange. Ling Jianjun, the founder of Lingzhi Equipment Group and a foreign academician of the Russian Academy of Engineering, accompanied the research team throughout the visit and led them to focus on visiting the first intellectual property museum in China's environmental protection industry.

In the Intellectual Property Museum, Academician Ling Jianjun systematically introduced the company's 30-year innovation trajectory in the environmental protection field by combining the display boards, multimedia demonstrations and physical exhibits in the museum. Since its establishment in 1996, Lingzhi Equipment has always focused on the core track of sewage treatment equipment, forming a full-chain solution covering rural sewage treatment, urban sewage treatment, industrial wastewater treatment and seawater desalination. The related achievements have been solidified through 218 valid authorized patents, among which the international patent layout has extended to 8 economies including the United States and the Netherlands. The research team focused on the SDD new low-carbon sewage treatment equipment technology achievements on display in the museum. This equipment adopts a "modular building block" design, with a construction efficiency 60% higher than the traditional solution. It has achieved a 40% weight reduction and low carbon emissions through the application of hollow core board materials. It has successfully served overseas projects such as the leather industrial park in Bangladesh and the water resource recycling project in Saudi Arabia.

During the subsequent discussion and exchange, Academician Ling Jianjun further shared his practical experience in the transformation of intellectual property rights: The combined oxidation ditch process developed by the enterprise once achieved A breakthrough of the first-level A standard for effluent from sewage treatment plants for the first time. Now, through intellectual property protection and iteration, the upgraded SDD technology has achieved an 82% reuse rate of industrial wastewater, and the related equipment has been included in the list of national environmental protection equipment manufacturing enterprises with standardized conditions.

During the discussion session, President Sun Hualin, based on the actual development of the environmental protection industry in Tianjin, stated: "Lingzhi Equipment's model of deeply integrating patented technology with actual demands provides a model for Tianjin's environmental protection enterprises to solve the problems of 'high R&D investment and low conversion efficiency'. In the future, it can promote the technological connection between enterprises in the two places." Secretary Ma Hongbing, starting from the ecological governance demands of the Northeast region, pointed out: "Jilin has urgent needs in areas such as black soil protection and cold region sewage treatment. If Lingzhi's modular equipment and low-carbon technology can be implemented in Jilin, it will effectively fill the regional technological gap. We look forward to deepening cooperation through intellectual property cooperation as a bond."

In addition, representatives from environmental protection industry associations in many places highly recognized Lingzhi Equipment's development model of "building innovation with intellectual property rights", believing that its 30-year dedication to the research and development of environmental protection equipment has set a benchmark for technological innovation in the industry. Qian Pingping, the chairman of Global Group, based on his own experience in enterprise transformation, said, "Lingzhi's modular technology and intellectual property management system are highly valuable for reference and provide a clear path for traditional environmental protection enterprises to upgrade to high-end manufacturing." Chen Zhi 'an, the founder of the Huan Xiao Er Industrial Service Platform, pointed out from the perspective of the industrial ecosystem that Lingzhi's accumulation of intellectual property rights not only empowers the company's own development but also provides technical support for collaborative innovation in the industry, which is highly consistent with the platform's concept of promoting the digital transformation of the industry. Kong Weimin from Yixing Environmental Protection Association stated that as a benchmark enterprise in Yixing's environmental protection industry, Lingzhi's innovative practices will drive the regional industrial cluster to upgrade towards "technology-intensive".

The research team unanimously agreed that Lingzhi Equipment's approach of integrating innovative resources and showcasing technological achievements through the Intellectual Property museum has built an important communication platform for the environmental protection industry. This research has built a bridge for cooperation between environmental protection enterprises and associations in various regions. In the future, all parties will deepen collaboration in the forms of technology sharing and patent cooperation to jointly promote the high-quality development of the environmental protection industry.
