ENCLOSED BIOFILTER MEDIA FOR THE CONTROL OF ODOROUS AIR CONTAINING H2S AND PREPARATION PROCESS THEREFOR |
摘要 |
PURPOSE: A microbe media for enclosed biofilter system is provided to treat odorous air containing H2S with low-pressure loss and extended retention time because the microbe media is composed of earthworm castings and bark, which have high porosity. CONSTITUTION: The microbe media for enclosed biofilter system is prepared by blending earthworm castings and bark in the volume ratio of 4:1. The microbe media has a porosity higher than 60%, and does not show sharp increase in pressure loss(± 0.53mmH2O) over extended operation time. Furthermore, it displays neutral pH range even after operating in pH 7-8.
