Waste Activated Sludge Alkaline Fermentation Liquid as Carbon Source for Biological Nutrients Removal in Anaerobic Followed by Alternating Aerobic-Anoxic Sequencing Batch Reactors
TLDR
In this paper, waste activated sludge alkaline fermentation liquid was used as the main carbon source for phosphorus and nitrogen removal under anaerobic followed by alternating aerobic-anoxic conditions, and the results were compared with those using acetic acid as the carbon source.About:

Achieving partial denitrification with sludge fermentation liquid as carbon source: The effect of seeding sludge
TL;DR: As much as 80% nitrate-to-nitrite transformation ratio (NTR) was achieved in a 108-day operation with inoculating SA-A, which illustrated the stability of partial denitrification under long-term operation.

Enhanced nitrogen and phosphorus removal from municipal wastewater in an anaerobic-aerobic-anoxic sequencing batch reactor with sludge fermentation products as carbon source.
TL;DR: The AOA-SBR demonstrated potential to solve the dual problem of insufficient carbon source and sludge reduction and achieved simultaneous partial nitrification and denitrification, aerobic phosphorus uptake and anoxicDenitrification through the real-time control and the addition of sludge fermentation products.

Acidogenic fermentation characteristics of different types of protein-rich substrates in food waste to produce volatile fatty acids.
TL;DR: The results showed HT pretreatment could improve the VFA production of tofu but not for egg white, and the optimum VFA yields were 0.46g/gVS (tofu with HT) and 0.26g/ gVS (egg white without HT), respectively.
