摘要
针对造纸生产中的石灰法和低碱法草浆混合黑液进行发酵试验研究 ,CODcr去除率达60 7 %～70 4 % ,BOD去除率达90 4 % ,SS平均去除率为92 1 % ,容积负荷为5～7kg[CODcr]/(m3·d) ,每立方米废液回收沼气9 11m3。
Fermentation test and study of the mixed black liquor from lime and low_base processes in papermaking industry were carried out.COD Cr removal ratio was 60.7%～70.4%, BOD removal ratio was 90.4%,and average SS removal ratio was 92.1%.Volumetric load was 5～7 kg/(m3·d).The recovery of methane per cubic meter of waste liquor was 9.11 m3.
