The greatest problem faced is foul smell caused by compost, does not influence ambient enviroment singly, also reduction fertility, and therefore, deodorization is compost
Important process link.Compost deodorizing mainly passes through three steps and is realized, respectively source emission reduction, process emission reduction and end-o f-pipe -control.
Currently, related deodorization process focuses primarily upon two stages of source emission reduction and end-o f-pipe -control, the technique of foul smell process emission reduction is rarely seen
Report.
Compost foul smell release can be divided into concentration release and two stages of unordered release, concentrate the release stage mainly turning with
0.5 to 1 hour after turning, other times were the foul smell unordered release stage.The release stage is concentrated in foul smell, since foul smell discharges
Measure huge, and concentration is high, influences very extensive.And in the foul smell unordered release stage, since heap body ventilation quantity is limited, and upper layer heap
Material has shadowing effect, and the foul smell burst size of compost is less.Therefore, the process emission reduction of compost foul smell should pay close attention to foul smell and concentrate release
