Suggest that you disuss this with people who have designed facilities for
raising laboratory animals, a somewhat similar situation in that there is a
high animal density with the production of high ammonia (not sure about
hydrogen sulfide, though) and moisture.

Generally, laboratory animal production depends upon the use of high rates of
air exchange (12 air changes per hour is common) and HEPA filters, rather than
the use of materials to remove airborne particulates.  Of course, plant
material in the form of hardwood shavings and similar plant materials are used
for the absorption of liquid wastes.
