Abstract

The invention discloses an anaerobic ammoxidation reaction device utilizing gas production for controlling water intake quantity. The anaerobic ammoxidation reaction device comprises two or more parallel-connection UASB reactors; a water intake pump (1) is arranged near the UASB reactors; each UASB reactor is provided with a separation zone (III), a packing zone (II) and an activated sludge zone (I) from top to bottom successively; each separation zone (III) is internally provided with a three-phase separator (11), a gas chamber (10) at the top of each three-phase the separator (11) is provided with an exhaust pipe (8); each packing zone (II) is internally provided with a packing layer (12); the center of the bottom of each activated sludge zone (I) is provided with a water intake distributor (13). The water intake quantity can be controlled according to the gas producing condition of anaerobic ammoxidation, and the water intake follows a principle that a substrate is fed when a reaction exists, so as to avoid blindly feeding the substrate.

Description

technical field [0001] The invention belongs to the field of biological denitrification reactors, and in particular relates to an anaerobic ammonium oxidation reaction device which utilizes gas production to regulate water intake. Background technique [0002] Anammox bacteria have very harsh requirements on growth conditions, and the generation cycle is long (11-30d), and the yield is low (0.11g / g NH 4 + -N) Enrichment culture is difficult. [0003] The anammox reaction is as follows: [0004] [0005] It is easy to know from the reaction formula that ammonia nitrogen and nitrous nitrogen are the substrates of the anammox reaction, and the main products are nitrogen and a small amount of nitrate nitrogen. Relevant literature pointed out that the substrate of anammox reaction is also an inhibitor, that is, the inhibition of free ammonia (FA) produced by high concentration of ammonia nitrogen and the inhibition of free nitrous acid (FNA) produced by high concentration o...
