Abstract

This invention discloses a multi-water differential flow water quality and quantity equalization tank, aiming to solve the problem of uneven water quality and quantity in traditional equalization facilities when treating multiple types of wastewater. The equalization tank includes: a sub-equalization tank, a main equalization tank, an outlet pipe, an automatic flow control valve, a collection tank, a water quality monitoring system, and a control system. The sub-equalization tank is designed with its volume according to the wastewater generation time and flow rate, and receives wastewater in real time. Wastewater from the sub-equalization tank enters the main equalization tank through the outlet pipe via the automatic flow control valve. The automatic flow control valve, through differential flow design, ensures that the wastewater from the sub-equalization tank flows evenly to the main equalization tank. A collection tank is installed inside the main equalization tank, allowing different types and flow rates of wastewater to enter and achieve rapid and uniform mixing. The outlet of the main equalization tank is equipped with a water quality monitoring system and a control system for real-time monitoring and control. This invention achieves stability and high efficiency in the treatment process and is suitable for various complex wastewater treatment scenarios.
