Abstract

The invention provides a denitrification treatment device and method for polluted water, and belongs to the technical field of polluted water treatment. When the denitrification treatment device for polluted water is used for treating polluted water, as corrugated pole plates are respectively connected to an anode plate and a cathode plate in an electrolysis device, and the corrugated pole plates can continuously enlarge and reduce the water passing section, when the water flows through the section, the turbulent flow in the flowing process can be increased. Therefore, the influence of concentration polarization is weakened to a certain extent, and the reaction rate and the removal rate of ammonia nitrogen and nitrate in the electrolysis process are enhanced. An ion exchange device can perform further denitrification treatment on the polluted water treated by the electrolysis device, so that the denitrification efficiency of the low-concentration ammonia-nitrogen wastewater can be further improved.

Description

technical field [0001] The invention relates to the technical field of polluted water treatment, in particular to a denitrification treatment device and treatment method for polluted water. Background technique [0002] With the development of society, the pollution of water sources is becoming more and more serious. At the same time, due to the improvement of the level of science and technology, the requirements for water quality are becoming more and more stringent in both industry and people's life, and the requirements for water quality are also getting higher and higher. The vast majority of people's drinking water comes from surface water or groundwater, and it is inevitable that excessive nitrate or ammonia nitrogen will exceed the standard in groundwater. For the excessive ammonia nitrogen in the wastewater, if it cannot be effectively removed, it will seriously affect the health of the human body after ingestion. For example, after a baby eats nitrate food, it will...
