The governance strategy of a river treatment project in Qingzhou, Shandong Province is based on the primary premise of "intercepting and managing pollution", "non-point source control", and "endogenous governance", increasing hydrological power and water supply, and using ecological restoration technology to build a long-term stable water ecosystem. The in-situ ecological restoration technology developed by the company can achieve synchronous treatment of polluted river water and riverbed silt. By using microbial carriers and aeration systems, the number of microorganisms capable of degrading organic matter, ammonia nitrogen, and phosphorus in the water is significantly increased, gradually restoring the self purification capacity of the water.
