Anaerobic ammonia oxidizing bacteria bioreactor

Abstract

The invention discloses an anaerobic ammonia oxidizing bacteria bioreactor which comprises a reactor body and a peripheral water bath device and is characterized in that a first-stage three-phase separation area and a second-stage three-phase separation area are overlaid to form a complete three-phase separation system; the two sides of the upper part of the second-stage three-phase separation area are connected through a flow guide tube; one side of the second-stage three-phase separation area is connected with a water outlet pipe; a baffle and an air outlet are arranged on the top of the second-stage three-phase separation area; the end port of the lower part of the second-stage three-phase separation area is connected with an end port of the upper part of a reaction chamber in a hot melting technique; the upper part of the first-stage three-phase separation area is connected with the inner wall of the lower part of the second-stage three-phase separation area in an inverted manner;and the lower part of the first-stage three-phase separation area is pasted on the inner wall of the upper part of the reaction chamber. With the adoption of the anaerobic ammonia oxidizing bacteria bioreactor, the temperature in a reactor tank body can be kept into a preset level, high effective denitrogenation is realized, and meanwhile, the sludge living weight is proliferated, so that fully separation of three phases of sludge, water and gas can be realized, sludge washing away is reduced to a large extent, the sludge amount of the anaerobic ammonia oxidizing bacteria in the reactor can be maintained, and the stable operation of an anaerobic ammonia oxidizing denitrification process can be ensured.

Description

technical field [0001] The invention belongs to the field of bioreactors, in particular to an anammox bacterial bioreactor. Background technique [0002] It is quite difficult to denitrify waste water and meet the discharge standards, which is one of the world's problems, and the newly discovered anammox denitrification process is considered to be the most promising technology to solve this problem. More than ten years ago, Delft University in the Netherlands discovered an unknown way for nitrogen to disappear when operating a three-stage biological denitrification fluidized bed reactor, and discovered anammox bacteria after in-depth research. In view of its great application prospects in wastewater denitrification, many people try to study the anammox denitrification process of anammox bacteria, and the research and continuous improvement of the anammox reactor is also an important subject of this technological progress . [0003] Anammox bacterial sludge has the characte...

Problems solved by technology

The patent application (CN201058827) is equipped with a three-phase separator, which has a certain three-phase separation effect and has a good interception effect on sludge with good sedimentation performance, but its retention capacity for sludge with poor sedimentation performance is insufficient

The invention patent application (CN101863554A) is equipped with a reaction chamber and a three-phase separation chamber, but the division of the three-phase separation chamber is not obvious, and the angle between the baffle plate of the separation chamber and the gradually expanding wall is small, and the sludge flow is easily blocked when the sludge flow is serious. Dead angle is formed, and there are also problems such as complex reactor structure, troublesome manufacture and difficult operation
