​River Basin Governance and Ecological Restoration

River Basin Governance and Ecological Restoration Project – Sanya City Bao Po Creek Bao Po Intersection to Beipo Bridge Water Environment Treatment Project

Project Overview: Bao Po Creek is a tributary of the eastern branch of Sanya River, with a total length of 15.3 kilometers, mainly flowing through Sanya Technician College and Dalingong Management Bureau. It converges into the Yuechuan Wetland at the Beipo Bridge and finally flows into the eastern branch of the Sanya River through the Dong'an Flood Diversion Channel. The section to be treated in this project is from Bao Po Intersection to Beipo Bridge, with a length of 1.4 kilometers and an area of about 80,000 square meters.

Technology Process: The project includes 13 specialized comprehensive treatment processes such as sediment modification, biofilm aeration, and composite ecological floating islands.

Treatment Effect: After treatment by Shangchen Environment, the water quality in the Bao Po Creek Bao Po Intersection to Beipo Bridge section of Sanya City has achieved partial surface V-class standards and some areas have reached surface water Class IV.

　　River Basin Governance and Black and Odorous Water Body Ecological Restoration Project

River Basin Governance and Black and Odorous Water Body Ecological Restoration Project – Yima City Jianhe and Shihe Ecological Comprehensive Treatment Project

Project Overview: Yima City has two rivers, Jianhe and Shihe, running through the city, with a total length of 28.098 kilometers. Jianhe is a tributary of the Luo River, originating from the eastern foot of Matou Mountain in Guanyin Village, Shanxi County. It flows east to west through the city, with a length of 19.298 kilometers within Yima and a current channel width of 50-170 meters. Shihe is located in the northwest of Yima City and flows north to south through the city. It is a tributary of the left bank of Jianhe and is a seasonal river, flowing into Jianhe at Shihe Village with a total length of 8.8 kilometers.

Main Construction Content: River ecosystem restoration, water quality purification, waterfront landscape, and specialized construction.

Cooperation Period: The cooperation period of this project is 12 years, including a construction period of 2 years and an operation period of 10 years.

　　River Basin Governance and Black and Odorous Water Body Ecological Restoration Project

　　Shangchen Environment Service Process:

　　Shangchen Environment's river basin governance technology primarily employs a combination of biological and physical methods, focusing on the use of in-situ restoration technology that does not require dredging to restore the ecosystem and self-purification capacity of the basin, effectively improving water quality, preventing soil erosion, and enhancing the environment.

　　Shangchen Environment Service Features:

　　Utilizes NVO200 biological nanofiber aeration devices to eliminate organic pollution and black and odorous conditions, improve water color and transparency, effectively promote the growth of aquatic organisms, and reduce organic matter in the water.

　　Employs the WYS active composite enhanced floating island purification system to create an environment conducive to microbial growth and reproduction, obtaining a large number of highly biologically active microorganisms to enhance their efficiency in oxidizing and decomposing organic matter.

　　Uses Shangchen Environment's proprietary microbial activation devices to release bioreactive agents, improve and optimize the microbial ecosystem, enhance system biological activity, and increase the effective biomass and functionality of microorganisms.

　　Utilizes bio-based and biomimetic aquatic plants as microbial carriers without affecting the navigation and flood discharge functions of the river, and does not damage the river (water body) ecosystem.

　　Utilizes the root system of aquatic plants to absorb nutrients such as nitrogen and phosphorus from the sediment, converting them into the structure of the plants, thereby fixing nitrogen and phosphorus in the water and reducing their concentrations, purifying the water.

　　Stabilizes the sediment over the long term using Shangchen Environment's technology to eliminate the black and odorous conditions of the river.

　　Selects and designs a side filtration device based on water quality characteristics, using modular design that can be flexibly arranged according to the terrain needs.

　　Utilizes Shangchen Environment's developed mobile water quality monitoring platform, with an APP data receiving device, to understand the water quality status of the river in real-time.
