Abstract

The invention discloses an ammonia nitrogen / total nitrogen treatment device and method. The device comprises a high-frequency pulse switching power supply, a self-made titanium alloy plate electrode, a plate electrode surface coating, a self-designed circulating water inlet / outlet system, a self-designed reaction tank and a connection system, wherein the electrifying mode of the high-frequency pulse switching power supply is direct current forward-power cut-forward; and the plate electrode surface coating is proportionally prepared from activated carbon powder (or supercapacitor activated carbon powder), polyvinylidene fluoride and conductive powder. The method comprises a circuit connection mode that the self-designed plate electrode is connected in parallel to the high-frequency pulse switching power supply. When being used for treating brine wastewater by high-frequency pulse power supply adsorption, the ammonia nitrogen / total nitrogen treatment device has the advantages of low energy consumption for every ton of brine wastewater, stable treatment effect, high speed of reaction balancing, and small secondary pollution, and has obvious advantages as compared with other methods.

Description

technical field [0001] The invention belongs to the technical field of environmental engineering, and in particular relates to an ammonia nitrogen and total nitrogen treatment device and method. Background technique [0002] With the rapid development of urbanization and industry in our country, the problem of water pollution has attracted people's attention. A large amount of domestic sewage and industrial wastewater containing nitrogen and phosphorus flow into rivers, lakes and groundwater, causing serious pollution to water bodies such as fishery water and domestic water. Urban sewage pollution has become one of the important factors restricting my country's economic development. In this context, the State Environmental Protection Administration first proposed in [2005] No. 110 "Notice on Strictly Implementing Pollutant Discharge Standards for Urban Sewage Treatment Plants" that "in order to prevent eutrophication of water areas, urban domestic sewage When the effluent ...
