Problems solved by technology

Theoretically, the denitrification process can only be realized when the carbon-nitrogen ratio is greater than 5-10:1. However, for high-concentration nitrogen sewage, there is a problem that the carbon-nitrogen ratio is too low. In order to complete the denitrification process, an additional carbon source is required.

Abstract

The invention provides a denitrification magnetotactic bacterium separation and culture device which comprises a denitrification tank, a magnetic separation device and a bacterium incubator. The denitrification tank is positioned at the top of the magnetic separation device, the bacterium incubator is positioned at the bottom of the magnetic separation device, and the denitrification tank, the magnetic separation device and the bacterium incubator are connected through clamping grooves and can be disassembled for use. The denitrification magnetotactic bacterium separation and culture device has advantages that the conversion rate of nitric nitrogen and nitrite nitrogen into gaseous nitrogen can be increased; due to integration of denitrification and denitrification magnetotactic bacterium separation and culture, convenience in use and experimental application is achieved.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a device for separating and cultivating denitrifying magnetotactic bacteria and a method for using the same. Background technique [0002] There are many ways to complete the denitrification process. At present, microbial methods are the main method, because nitrifying bacteria are autotrophic aerobic microorganisms, and denitrifying bacteria are mostly heterotrophic anaerobic microorganisms, so in sewage treatment, it usually depends on controlling dissolved oxygen. And adjust the carbon source to better realize the denitrification process. Theoretically, the denitrification process can only be realized when the carbon-to-nitrogen ratio is greater than 5-10:1. However, for high-concentration nitrogen sewage, there is a problem that the carbon-to-nitrogen ratio is too low. In order to complete the denitrification process, an additional carbon source is require...
