Since its faltering start in April 1996, Lingzhi Equipment has remained committed to its core business of environmental protection equipment by April 2026, with the unwavering determination to "do one thing well for a lifetime". It has forged ahead in the wave of sewage treatment, interpreting its original aspiration through persistence and fulfilling its green commitment with innovation, writing a story of perseverance and breakthrough for Chinese environmental protection enterprises.

I. 30 Years of Commitment: A "Deep Cultivator" in the Main Business of Environmental Protection Equipment

In the early days of its establishment, Lingzhi Equipment started by focusing on rural water treatment equipment. With a simple factory and immature technology, it took root in the environmental protection field because of its simple sentiment of "making sewage clear". In 2018, Lingzhi introduced Japanese purification tank technology. It was not a simple "copying", but a localized innovation to create a "home appliance" water purification device suitable for rural families. This was Lingzhi's first expansion of its original intention of "environmental protection for the people", and it also made the belief of "technological breakthroughs in treating sewage" more and more firm through repeated market tests.

Looking back on its development history, Lingzhi Environmental Protection has made many industry firsts: In 2006, it was the first in the industry to propose the concept of above-ground and prefabricated sewage treatment plants, breaking the shackles of traditional models with innovative ideas. In 2007, the Wuxi Chengbei Sewage Treatment Plant was built, becoming the first project in the industry to achieve the first-class A standard for effluent, setting a benchmark for the industry. Over the past 30 years, the market has been in a state of constant hustle and bustle. While some have pursued diversified expansion, Lingzhi Equipment has refined "environmental protection equipment" into its sole "diamond tool". From the treatment of the "capillaries" of rural sewage, to the purification of the "main arteries" of urban sewage treatment plants, to the resolution of the "difficult and complicated problems" of industrial wastewater, and even extending to seawater desalination and reclaimed water reuse, all businesses are closely tied to the "water" pulse, and all innovations point to the word "clean". Entering the Qingyuan Sewage Treatment Plant in Linhai, Zhejiang Province, the equipment is operating in an orderly manner. The treated clear water flows out gurgling and is crystal clear. This modern sewage treatment plant, built by Lingzhi Equipment, is a vivid reflection of its focus on its main business. What has changed is the technological iteration, but what remains unchanged is the main business ethics of "only doing environmental protection equipment".

Ii. Innovation-driven: The "Game-Changer" of Sewage Treatment Equipment

The production workshop of Lingzhi Equipment conceals the "innovation code" of environmental protection equipment. The SDD new quality low-carbon sewage treatment equipment is by no means a simple accumulation of technologies. Instead, it is the culmination of Lingzhi's nearly 30 years of technological and process achievements - based on the oxidation ditch technology gene, it incorporates new technologies such as MBR, integrates the concepts of low-carbon, standardization, and artistry, deeply fuses the advantages of prefabrication with new standardized assembly, and consolidates 30 years of dedication into the "innovation gene". Integrate into every "low-carbon building block".

This set of equipment discards the heaviness of traditional concrete and uses a "smart panel" with thin-walled core tubes sandwiched between double-sided stainless steel thin plates to achieve "climate self-adaptation". In cold regions, fill in insulation cotton and hot water pipes to ensure the activity of microorganisms. Optimize ventilation in hot and humid areas to reduce energy consumption. This "modular building block" design enables installation to be like building with Lego, allowing workers to flexibly assemble on-site according to the size of the site and the scale of processing. In the sewage collection and treatment project of towns and townships in Fuyuan, Yunnan Province, 10 towns were covered and 11 sewage treatment stations were built. It is suitable for complex terrains such as mountains and river valleys, and the speed was increased by 60% compared with the traditional solution. The advantages of "modular building blocks" were fully demonstrated. What is even more commendable is the "ambition" of technological integration. The unique dual-membrane oxidation ditch process integration technology turns sewage treatment into a "production line operation", allowing sewage to complete deep purification in the "intelligent water treatment tool". The land occupation is reduced by 45% compared with traditional schemes, and the construction period is shortened from one year to less than two months.

Many projects, including the Nanyang Second Sewage Treatment Plant in Linhai, Zhejiang Province, have chosen it to assist in sewage treatment. Lingzhi Equipment has made sewage treatment equipment truly the "master key" for sewage treatment through innovation. The SDD equipment, which integrates over 200 core technologies of the enterprise, has also received 14 patent authorizations and software Copyrights, becoming a "star product" in the industry.

Iii. Heartfelt Implementation: The "Practitioners" of Green Commitments

The 30 years of Lingzhi Equipment have been 30 years of environmental protection sentiments turning into reality. In the Fuyuan project in Yunnan Province, 78.6 kilometers of pipelines connect 10 towns. The sewage treatment stations act like green guardians protecting the mountains and waters. The treated effluent strictly complies with the first-level A standard of the "Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants" (GB18918-2002), significantly improving the water environment of the local towns. At the Qingyuan Sewage Treatment Plant in Linhai, Zhejiang Province, SDD equipment has turned sewage into clear water, setting a new benchmark for regional water environment governance. Among these projects, "First-Class A standard" is the bottom line, and "ecological recovery" is the goal. Lingzhi Equipment uses its equipment to make "environmental protection not just a slogan, but a visible change".

What is even more touching is the warmth of "sharing". Open up modular design experience to drive small and medium-sized enterprises to enter the environmental protection field. Train over 2,000 grassroots technicians and spread pollution control technologies to counties and rural areas. After 30 years of dedication, Lingzhi Equipment has transformed from a "lone ranger" to an "ecological co-builder", weaving the "environmental protection equipment dream" into the grand picture of national water governance and the green transformation of the industry. The SDD new quality low-carbon sewage treatment equipment that has been put into use in many places such as Zhejiang, Yunnan and Shanxi is the most powerful testimony to this sentiment.

For 30 years, Lingzhi Equipment has been committed to environmental protection as its background and equipment innovation as its brush, painting a long scroll of "concentration, innovation and sharing" on the canvas of sewage treatment. In the next 30 years, this passion and perseverance will surely continue to drive Lingzhi Equipment to forge ahead in the ocean of environmental protection equipment, allowing the light of China's environmental protection technology to illuminate more green mountains and clear waters, and persistently and innovation-driven to keep keeping the green promise.
