Among them, chemical oxygen demand and dissolved oxygen meet the Class V water quality requirements for surface water. The Puning section of the Lianjiang River has basically said goodbye to the black and smelly environment, its ecological functions have gradually recovered, and the beautiful scenery of clear water and green shores has returned. </p
