Anaerobic ammonoxidation bacterium concentrating device

Abstract

The invention discloses a high- efficient enrichment device of the anaerobic ammonium oxidation bacteria. The lower circular cylinder of the main body of the device is connected with an upper circular cylinder through an increasing coupling, a sealing cover is arranged at the top part of the upper circular cylinder, an air outlet pipe is arranged on the sealing cover and is connected with a gas washing bottle, grain bamboo charcoal carriers are installed at the lower part of the lower circular cylinder, a primary gas-liquid-solid three phase separating component is arranged inside the upper circular cylinder, a secondary mud water separating component is arranged on the outer side, a grain sludge blocking component is arranged between the secondary mud water separating component and the upper circular cylinder, a grain sludge collecting opening is arranged at the lower part of the secondary mud water separating component, a overflow dam is arranged at the upper part of the grain sludge blocking component and is connected with a water outlet tank through a water collecting pipe, a water inlet pipe is arranged at the bottom part of the lower circular cylinder and is connected with the water inlet tank through a water inlet pump, a returning pipeline is arranged on the side wall at the middle part of the upper circular cylinder, and the returning pipeline passing a returning pump directly enters into the water inlet pipe through a three way pipe. The invention can block the anaerobic ammonium oxidation bacteria on the surface of the carrier, and obtains the enrichment culture of the anaerobic ammonium oxidation bacteria with high activity; the culture presents red, and the character is obvious; the culture is grain sludge, and is easy to be obtained.

Description

technical field [0001] The invention relates to an environmental protection device, in particular to an anammox bacteria enrichment device. Background technique [0002] Anammox bacteria are a newly discovered anaerobic autotrophic bacteria, which can convert ammonia nitrogen and nitrite nitrogen into nitrogen at a ratio of 1:1.32. They have special cell structure and physiological characteristics, and have both scientific research value and development value. Excellent, and has attracted much attention from the biological and environmental engineering circles. However, because the generation time of anammox bacteria is as long as 11 days, and the cell yield is very low, it is difficult to obtain enriched cultures with traditional microbiological methods. Therefore, research on new enrichment methods and devices is very important for promoting anammox The study of the mechanism and the application of the anaerobic ammonia oxidation process have important practical significa...
