Abstract

The invention discloses an electrochemical reactor for processing nitrogenous organic wastewater, and an application and a processing method thereof, and belongs to the field of processing nitrogenous organic wastewater. The device comprises a reaction container, a power supply, a gas outlet pipe, a water outlet pipe, a water outlet pipe valve and a water inlet system, and further comprises a packing material, a negative plate and a positive plate, wherein the packing material is formed by mixing active carbon and magnet particles; the negative plate is connected with the negative electrode of the power supply; the negative plate is a silicon dioxide plate loaded copper-palladium coating electrode, and the coating material consists of Pd and Cu at a mass ratio of 6: 1; and the positive plate is a digital subtraction angiography (DSA) oxide coating electrode Ti / IrO2-PtO2. The reactor is a batch-type operation three-dimensional electrode reactor which adopts a mixture of active carbon particles and magnet particles with similar diameter as the packing material, and has the functions of efficiently removing nitrate nitrogen, ammonia nitrogen and COD (chemical oxygen demand), and is low in energy consumption; and the reactor is capable of achieving a purpose of removing nitrogen and COD in the nitrogenous organic wastewater.

Description

technical field

[0001] The invention belongs to the field of nitrogen-containing organic wastewater treatment, and more specifically relates to an electrochemical reactor for treating nitrogen-containing organic wastewater. Background technique

[0002] In recent years, due to the use of pesticides and fertilizers, nitrate has become a major pollutant in water bodies. Studies have shown that drinking water with high nitrate content can lead to increased hemoglobin in infants and related cancers in adults. Methods and processes for removing nitrate from water include membrane filtration, ion exchange, biological denitrification, electrochemical denitrification, etc. Among them, electrochemical denitrification has fast denitrification efficiency, good denitrification effect, and no secondary pollution. And it has a certain removal effect on COD, so it has attracted the attention of many researchers. However, the high energy consumption and high operating cost of the electroc...
