- Abstract:
- There are widespread problems at the end of urban water supply, such as poor water quality and insufficient residual chlorine. Chlorination in secondary water supply is an effective way to improve the end water quality and ensure the safety of user’s tap water. This paper developed an intelligent secondary water supply chlorination system and applied it in a community in Yinchuan City. The water consumption characteristics were analyzed, and the corresponding dosing mode was adopted to investigate the operation of the dosing system and the control of residual chlorine in user’s tap water. Based on the incremental PID control algorithm, the composite loop control integrated open loop feedforward control dosing and closed loop control feedback regulation was adopted to discretize the whole system to adapt to the changes in water quality and quantity, and realized the dynamic adjustment dosing, so as to accurately control the residual chlorine concnetration in water.
