Gelonghui, May 15 | Cathay Pacific Environmental Protection (301203.SZ) said on the investor interactive platform that the company's main technologies in the field of ecological environment restoration include river and lake sediment pollution control technology, water diversion purification technology, and ecosystem recycling purification technology. River and lake sediment pollution control technology is mainly for the cleaning, treatment and disposal of polluted rivers and lakes. It is one of the keys to the river and lake water environment treatment system. Through river and lake sediment disposal technology, pollutants at the bottom of rivers and lakes are cleaned up, and through a series of measures such as reduction, harmlessness, and stabilization, the resource utilization of river and lake sediment is finally realized. Water diversion and purification technology improves river hydrodynamic conditions by analyzing the total inbound pollution load in the watershed, fully exploiting watershed water resources for river water supply, adopting hydraulic control methods, improving the quality of water replenishment, and enhancing water circulation. Ecosystem recycling and purification technology establishes a stable “aquatic plant-aquatic animal-microbial community” symbiosis system, restores the “grass-type freshwater state” self-purification system, and improves the self-purification capacity of water bodies and the quality of the water environment. Relying on the above core technology system, the company undertook Hangzhou Asian Games environmental protection projects such as the “2023 Asian Games Water Environment Guarantee Project (Qiantang District)”, the “Chengxiang Street Asian Games Water Quality Assurance Government Procurement Project”, and the “Baiyang Street Canal 5 Ecological Treatment Project” and other ecosystem recycling and purification demonstration projects such as the “Baiyang Street Canal 5 Ecological Treatment Project”.
