Abstract

In order to minimize carbon emission during wastewater treatment process, the invention brings forward a multistage contact oxidation reaction device for simultaneous carbon and nitrogen removal of wastewater and a method thereof and belongs to the field of domestic and industrial wastewater treatment. The device is composed of several monomer units which are openmouthed cavities. The cavities are provided with water inlets and water outlets. A filling material is arranged inside each cavity, and microbes capable of treating wastewater are inoculated in the filling material. Combination mode of the monomer units in the device is a combined-type or an integrated type. According to the method, wastewater passes through a first reaction stage for treating organic matter, a second reaction stage for treating ammonia nitrogen and a third reaction stage for treating organic matter and ammonia nitrogen simultaneously. Then, organic matter and ammonia nitrogen in the wastewater are efficiently removed, removal rate of effluent COD is greater than 90%, ammonia-nitrogen removal rate is greater than 95%, and removal rate of total nitrogen is greater than 90%. The device is simple and practical. By the method, organic matter in wastewater can be removed while simultaneous removal of ammonia nitrogen is realized, and problems of long time, high energy consumption and high cost existing in traditional technologies are thoroughly solved.

Description

technical field [0001] The invention belongs to the field of domestic and industrial wastewater treatment, in particular to a multi-stage contact oxidation device and method for synchronously removing carbon and nitrogen from refractory wastewater containing high concentrations of organic matter and ammonia nitrogen. Background technique [0002] As the country's requirements for environmental quality increase, the standards for pollutant discharge also increase. At the same time, my country has recently committed to lower carbon emission standards in the world, so many industries also regard energy conservation and emission reduction as an important indicator to investigate and take measures to reduce carbon emissions. Although the environmental protection industry contributes to energy conservation and emission reduction, it also needs energy, especially when dealing with pollutants, energy consumption brings carbon emissions. Taking ammonia nitrogen treatment as an examp...
