Yu Zecun's Nirvana Record: The Technological Butterfly Transformation from "Black Water Pond" to "Ecological Pearl".

In September 2023, the water quality alarm in Yuzhe Village, northern Zhejiang Province, pierced the sky. This ancient village in Jiangnan, with a history of nearly 600 years, has suddenly turned its pond into a glaring ecological scar - the water is covered in a strange yellow green color, and the stench of gas permeates the entire village. The data from the ecological environment monitoring station shows that dissolved oxygen is approaching zero, ammonia nitrogen exceeds the standard severely, and water quality has fallen below the Class 1 standard.

In this sudden ecological crisis, the technical team of Yongkang Zhongyi Industry and Trade rushed to the rescue with their independently developed FG adsorption material.

Project Director Chen recalled, "The silt layer reaches 30 centimeters, and traditional dredging can cause secondary pollution. We innovatively adopted an in-situ remediation solution to evenly inject FG material into the polluted layer." The nano scale pore structure of this material is like a miniature "ecological surgical knife", which can effectively fix heavy metal ions, adsorb organic pollutants, and then recycle the adsorbent material. The water surface immediately returns to normal cleanliness.

The technological breakthroughs during the tough period are exciting: in response to the difficult to degrade phthalate pollutants, the engineering team adjusted the material ratio overnight and innovatively added biodegradable materials to improve the decomposition efficiency., Environmental volunteer Captain Wang presented monitoring data: "On the 5th day, COD dropped to 45mg/L, on the 12th day, transparency exceeded 1.2 meters, and the final water quality stabilized to meet Class III standards

The village branch secretary sighed, "Zhongyi's pollution control methods not only restored the pond, but also preserved our nostalgic memories. What they brought was not short-term governance, but sustainable ecological wisdom

Yongkang Zhongyi Industry and Trade has been deeply involved in the field of environmental protection materials for 17 years, and its FG series products have been successfully applied in various ecological restoration projects.
