Abstract

The invention provides a high-efficiency denitrification nitrogen removal device and a high-efficiency denitrification nitrogen removal method. The device comprises a water inlet part, a reaction part and a three-phase separation part which are sequentially connected in series, wherein the water inlet part comprises a water inlet used for allowing sewage and solid electron donors to enter; and autotrophic denitrification floras are arranged in the reaction part. When the sewage is treated by utilizing the nitrogen removal device disclosed by the invention, the nitric nitrogen treatment efficiency is high, secondary pollution is avoided, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a high-efficiency denitrification and denitrification device and method. Background technique [0002] As the nitrogen content discharged into the water body increases year by year, the eutrophication of the water body becomes more and more serious, which leads to the deterioration of the water quality and even the degradation of the lake. Due to long-term eutrophication, most freshwater systems in my country have become very fragile, and the removal of nitrogen in water has become a hot spot in water pollution control. [0003] At present, the methods for removing nitrate nitrogen (nitrogen in the form of nitrate ions) include biological methods, physical and chemical methods, etc. Among them, biological methods are widely used in sewage treatment due to their advantages of low energy consumption and high efficiency. Biological heterotrophic denitrification process is c...
