Anaerobic ammonia oxidation reactor

Abstract

The invention discloses an anaerobic ammonia oxidation reactor. The anaerobic ammonia oxidation reactor comprises a reactor barrel body and a circular flow guiding barrel, wherein a liquid inlet is formed in the upper portion of a flow pushing assembly in the circular flow guiding barrel; an upper flow guider assembly is arranged on the upper portion of the liquid inlet; a lower flow guider assembly is arranged on the lower portion of the circular flow guiding barrel; a sewage inlet tube is arranged on one side of the reactor barrel body; an anaerobic ammonia oxidation mycoderm carrier fillerregion is arranged in the reactor barrel body; a plurality of three-phase separators are symmetrically arranged on the top of the upper flow guider assembly; a sewage outlet is formed in the bottom ofthe reactor barrel body, and communicates with a water inlet of a circulating pump; a water outlet pipe of the circulating pump communicates with a serpentine pipe in a water-bath pre-heating tank; and a water outlet pipe of the serpentine pipe communicates with a water inlet pipe. The anaerobic ammonia oxidation reactor is high in treatment efficiency, large in sewage impact load resistance, lowin running cost and high in equipment integration degree, and runs stably.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an anaerobic ammonium oxidation reactor. Background technique [0002] The C / N of some urban sewage and most industrial sewage in my country is low, especially some industrial sewage with high ammonia nitrogen. In addition to the improvement of the effluent quality standard of sewage treatment plants, it is difficult to guarantee the denitrification efficiency by relying on the traditional denitrification process. [0003] Therefore, it is urgent to find a method for denitrification of low-carbon source sewage. In the anammox process, since the anammox bacteria are autotrophic bacteria, no carbon source is consumed during the reaction process, so if it can be applied to the above sewage treatment, it can effectively solve the problem of carbon source shortage in sewage treatment denitrification The problem. The phenomenon of anammox was first discovered in ...

AI Technical Summary

Problems solved by technology

[0011] (1) In the Anammox reactor, the biological productivity is low, and only a small amount of anammox bacteria can grow and reproduce. The system must have corresponding biological supplies, otherwise the reactor's processing capacity will decrease or even lose its function

[0012] (2) The biological productivity in the system is low, resulting in a relatively long hydraulic retention time, the required reactor volume is large, and the primary investment of the wastewater treatment project is relatively large

[0013] (3) The temperature required for the system reaction is high, and the environmental conditions and the required energy consumption must be considered in practice

[0017] However, at present, most of the research on ANAMMOX technology is still in the stage of small laboratory tests, and there is a lack of practical testing in large-scale actual projects.
