For the purpose of odor reducing in livestock industry,we used
ammonia and hydrogen sulfide as the odor indicater and carried
out a series of odor reducing experiment in the laboratory.
According to the screening test for the biofilter has shown
that the peat was the best biofilter to remove the NH3 and H2S
under pH 3~4 and 60% of water holding capacity of peat.The
physical 、chemical and biological properties of peat were
determined. The optimal composition of peat biofilter was the
full mixed of peat、KH2PO4(buffer)、rice bran(disperse agent)at
the rate of 10:1:1(w/w). For ammonia removing experiment,we
studied three test runs. In the first run,we observed its
chemical changes under different loading,and estimated the
mechanism of ammonia removing.In order to get the unit ammonia
removial capacity,we figured out the breakthrough curve in the
second run and got the value of 27.5 g-N/kg dry peat at last.It
is a wonderful ammonia removal capaci -ty.In the third run,we
compared the ammonia removal capacity with sterilzed and
nonsterilized peat biofilter under the same operation
conditions ,we found that ammonia removing were pri -marily due
to the peat adsorption and microbial biosynthesis. For hydrogen
sulfide removing experiments,at first,we bserved its chemical
changes under different loading,and dis-ussed the reason that
there was not apparent biological reacationIn the second run,we
used Michaelis-Menten equation to obtain theaximum removal
rate--1.6g-S/kg dry peat.On the other hand,we knewhat there is
a best removal capacity of 1.6g-S/kg dry peat underoading of 3~4
g-S/kg dry peat、a best removal capacity of 1.2gS/kgry peat
under inlet concentration of 213ppm,and a best removalfficiency
of 93.5% under space velocity of 72/h .They are theest
operation condition for hydrogen sulfide removing.
