This process diagram elaborately explains the main steps in urban wastewater treatment, including sewage inflow (Influent), transportation by pump stations (Pump) to screen out large impurities (Screen), followed by sedimentation separation in clarifiers (Clarifier), and flow control through valves (Valve) into aerated tanks (Aerated Tank) for biological treatment, before meeting discharge standards or reuse. The entire process effectively removes harmful substances from the wastewater, protecting the environment.
