Study on Energy-Saving Electronic Water Treatment Facility with Automatically Adjustable Operating Voltage

Abstract:

When wastewater is treated with an electronic water treatment method, hardness, alkalinity and conductivity of the wastewater decrease much slower with time on. If the operating voltage of wastewater treatment is reduced at this time, the purpose of energy saving can be realized while wastewater treatment efficiency is guaranteed. Existing electronic water treatment facilities always realize water treatment with constant low voltages and almost all of them have no optimal design about energy saving, water treatment system rust reduction, water treatment automation, etc. To solve these problems, a new energy-saving electronic water treatment facility is designed in this paper. Based on a low-power SCM MPS430F169 and circuits such as the water treatment voltage control circuit and the voltage and current sampling circuit, the facility establishes a closed-loop system with functions of water quality monitoring and automatic water treatment voltage adjustment. Experimental results show that the facility can realize real-time water quality monitoring in the process of wastewater treatment and automatically adjust operating voltage in line with the water quality, thus significantly reducing unnecessary energy consumption. The facility can be used in fields such as industrial circulating water treatment.
