Abstract

The invention discloses a small electro-adsorption system for drinking groundwater treatment and a use method thereof, and relates to the field of drinking water treatment. The invention aims to solve the technical problem that the electric adsorption efficiency is influenced due to small contact area between water flow and electrodes of the existing electric adsorption equipment. The system comprises electro-adsorption devices, a raw water tank, a purified water tank, a waste water tank, an electromagnetic valve and a security filter. The electro-adsorption devices comprise an A group of electro-adsorption device and a B group of electro-adsorption device, and each group of electro-adsorption device comprises a plurality of adsorption units. The two groups of electro-adsorption devices of the system are connected in parallel and operate alternately to obtain continuous purified water. According to the system, the contact area of raw water and the electrodes is large, scaling is not prone to occurring, the electro-adsorption efficiency is high, and a good desalting effect is achieved. The system is used for underground water treatment.

Description

technical field [0001] The invention relates to the field of drinking water treatment. Background technique [0002] Groundwater plays a vital role as a source of drinking water in rural areas, but groundwater contains a certain concentration of inorganic salt ions, such as chloride ions, sulfate ions, nitrate ions, fluoride ions, calcium ions, magnesium ions, high concentrations Inorganic ions pose a threat to human health, and these inorganic ions have poor biochemical properties and are difficult to treat. At present, reverse osmosis, ion exchange, and membrane osmosis are commonly used, but these methods have different degrees of limitations in the treatment of rural drinking groundwater. shortcoming. [0003] Electrosorption technology is a technology for removing ions in water based on the electric double layer theory. It has the advantages of low energy consumption, easy maintenance, low cost and no secondary pollution. Electrosorption technology also has a good appl...
