Embodiment 1

[0033] A nitrogen removal method for organic waste liquid, comprising:

[0034]S1. A titanium plate is used as the anode 100 and a graphite plate is used as the cathode 200, and the anode 100 and the cathode 200 are fixed on both ends of the insulator 300 to form a reaction cell; a reaction cell is arranged in every 100mL of organic waste liquid.

[0035] Among them, the organic waste liquid is landfill leachate, and the initial nitrogen content of the organic waste liquid is 217ppm; the specifications of the anode 100 and the cathode 200 are the same, the distance between the anode 100 and the cathode 200 and the reaction cell configured in every 100mL of organic waste liquid The area is shown in Table 1.

[0036] S2. Using a DC power supply to apply a voltage to each reaction cell, so that the reaction cell performs electrolytic treatment on the organic waste liquid until the residual nitrogen content in the organic waste liquid is less than 5 ppm.

[0037] Wherein, the vol...

Embodiment 2-8

[0039] A nitrogen removal method for organic waste liquid, which differs from Example 1 only in that:

[0040] The distance between the anode 100 and the cathode 200 is different from that in Embodiment 1, please refer to Table 1 for details.

Embodiment 9-10

Abstract

The invention provides a nitrogen removal method for organic waste liquid, and belongs to the technical field of wastewater treatment. The nitrogen removal method of the organic waste liquid comprisesthe steps: performing electrolytic treatment on the organic waste liquid by adopting a reaction battery, so as to carrying out reaction on nitrogen-containing substances in the organic waste liquid to generate nitrogen. A reaction battery with the area of 15-25 cm<2> is arranged in each 100 mL of the organic waste liquid. Nitrogen-containing substances in the organic waste liquid can be quickly removed, and additives do not need to be added in the reaction.

Description

technical field [0001] The present application relates to the technical field of wastewater treatment, in particular, to a method for removing nitrogen from organic waste liquid. Background technique [0002] At present, the production sewage of various pharmaceutical factories and chemical plants, municipal domestic sewage, and leachate from landfills and incineration plants are usually organic waste liquids containing nitrogenous substances such as ammonia nitrogen or ammonia oxide in different amounts. In the prior art, the biological ammonia removal method is mainly used to remove ammonia from organic waste liquid, which has many processing steps and slow removal speed, and a large amount of additives need to be added in the reaction. Contents of the invention [0003] The purpose of this application is to provide a method for removing nitrogen from organic waste liquid, which can quickly remove nitrogen-containing substances in organic waste liquid, and does not need ...
