The company has unique insights and successful treatment experience in dealing with wastewater containing high COD, high ammonia nitrogen, high organic nitrogen, high salt content and strong biological toxicity in the energy and chemical fields such as "coal chemical industry, petrochemical industry and fine chemical industry". It can provide full-process and customized technical solutions ranging from pretreatment to advanced reuse treatment and even "zero discharge".

The company conducts resource recovery-oriented treatment on wastewater containing suspended solids and heavy metals in the mineral resource fields such as "coal mining and non-ferrous metal mining". This approach enables the reuse of water resources and the preliminary recovery of valuable metals.

The company adopts independent treatment routes for comprehensive wastewater containing cyanide, nickel, chromium, and refractory organic substances in other industrial fields such as "industrial park wastewater, electronic wastewater, and pharmaceutical wastewater", ensuring the wastewater can stably meet discharge standards.

The company has independently developed the "Chengxin Global Smart Environmental Protection Cloud Platform". By leveraging IoT (Internet of Things) technology, the platform enables remote monitoring, data analysis, intelligent chemical dosing, and fault diagnosis for projects across the country. This has realized the refined and intelligent management of projects, significantly improving operational efficiency and reducing costs.

Comprehensive perception, intelligent early warning, precise management and scientific decision-making are carried out for information such as hydrology, water quality, aquatic ecology and terrain of rivers.
