文摘

KW & CM were anaerobically digested at high organic loading to form acidification. VCBC and VC were employed as buffers to improve the anaerobic digestion of KW & CM. VCBC exhibited better acid buffering capacity than VC. CM can be well anaerobically digested with VC and VCBC addition. KW digestion was not initialized with VC and VCBC, but it tended to be alleviated.
