Abstract
The invention discloses an activated carbon filter coupling solar energy driven device for treating bitter salty water through membrane capacitive deionization and an application method thereof, and belongs to the technical field of bitter salty water treatment. The problems that MCDI electrode organic pollution is serious, effluent quality is poor and non-renewable energy resources are used for supplying power of an existing method for treating bitter salty water through MCDI are solved. The device comprises a raw water tank, a check valve, a raw water inlet valve, an activated carbon filter, a drainage valve, a back washing water storage tank, a back washing valve, intermediate water tank, an MCDI water inlet valve, an MCDI assembly, a regeneration valve, a concentrated brine storage tank, a fluid flowmeter or water meter, a water outlet valve, a clean water tank and a solar power supply system. According to the device, gravity flow exists in the whole application process, the water supply power cost is saved, meanwhile, working pressure is low, clean and renewable solar energy is used as the power supply, and power saving and environmental protection are achieved; effluent quality is improved, and MCDI organic pollution is avoided; operation is easy, the maintenance rate is low, and no chemical agent exists.
Description
technical field [0001] The invention belongs to the technical field of brackish water treatment, and in particular relates to a device for treating brackish water with low energy consumption, high efficiency, continuous and stable operation, and an activated carbon filter coupled with a solar-driven membrane capacitive deionization device and an application method thereof. Background technique [0002] With the rapid development of industrial society and rapid population growth, the demand for water resources is increasing day by day. The United Nations and the Organization for Economic Cooperation and Development report that by 2025, 390 million people in the world will be short of water. Due to climate change and unreasonable consumption of natural fresh water resources by industry, natural fresh water resources are decreasing day by day. At the same time, about 14% of fresh water resources in the world are polluted every year. These have exacerbated the shortage of water r...
