Environmental Protection Research Institute

Quanzhou Lanshen Environmental Protection Research Institute Co., Ltd. (hereinafter referred to as: Research Institute) was established on December 16, 2019. It is a collaborative innovation in the environmental protection industry that integrates technology research and development, technology introduction, achievement transformation, special research, consulting services, and talent training. platform.

The research institute follows the development concept of "technical innovation, process innovation, and material renewal", and is committed to rural sewage treatment, municipal sewage treatment, industrial wastewater treatment, ecological restoration, black and odorous water treatment, sludge reduction and recycling, and contaminated soil treatment. It provides technical support for environmental protection engineering construction and project operation.

At present, the research institute actively promotes in-depth cooperation with scientific research institutes such as Ocean University of China and Zhejiang University of Technology, and has established a team of experts composed of multi-disciplinary talents. efficiency, and boost the ecological environmental protection construction and regional economic development of villages and towns.
