Business Features

Overall Sewage Treatment Service Industry Chain

The company has established an overall sewage treatment service industry chain covering sewage network maintenance, pumping station management, sewage treatment plants operation, and comprehensive water environment management. It covers all mature sewage treatment applications in China, and has achieved Class A emission standards. The maximum daily treatment capacity of a single plant is up to 270,000 cubic meters.

Centralized Control Operation Management Model

We centrally manage and control all wastewater plants, draining pipeline networks, and pumping stations through our intelligent platform for wastewater treatment and smart platform for the wastewater pipeline network. This has ensured coordinated and optimized allocation of resources, which had reduced operating costs while at the same time, enabled unattended operation of wastewater treatment plants and pumping stations.

Plant-Network Integrated Operation

We provide professional pipeline network operation and maintenance services and ensure stable inlet water quality for wastewater treatment plants through close communication and collaboration between the two sides of the plant and network. This has improved the effect of wastewater treatment and provided a basis for the environmental supervision and planning of the drainage pipeline network for local government, thereby enabling harmless treatment at the end of the wastewater treatment process. The sludge generated from treating wastewater is incorporated into the company’s solid waste treatment process, achieving harmless treatment.
