Biological deodorization system for livestock manure liquid tank

摘要

The present invention primarily removes a high concentration of odor gas generated from livestock manure by passing through a liquid layer containing microorganisms, and a humidified gas (humid gas) is passed through a carrier packed bed to decompose and process biologically. In particular, it is economically designed to be suitable for domestic livestock manure liquid tank (200t) and is designed for the purpose of increasing the deodorization performance while being simple and compact in structure and size.;To this end, the present invention primarily passes the pig malodorous odor gas sucked by the suction pump 3 through the microbial solution 4 under the deodorization tower 1 and secondly through the porous ceramic carrier 5 in the upper middle portion. The gas deodorized by decomposition and adsorption through the exhaust port 6 is discharged. At this time, the water evaporated by bubbles of odor gas passing directly through the microbial solution 4 at the bottom periodically replenishes the microbial solution of the multifunctional auxiliary tank 2 to the deodorizing tower 1 by the spraying method, and the evaporated water. After this replenishment, the excess microbial solution overflowed from the deodorizing tower (1) relates to a deodorizing system characterized by the structure to return back to the multifunctional auxiliary tank (2) through the water level control pipe (9).
