文摘
- •
More biogas produced by adding food waste to low-organic-content sludge.
- •
No synergetic effect of co-substrate for biogas production at low solid concentration.
- •
Excessive acidification is the key risk inhibiting low-solids co-digestion.
- •
The blend ratio 1:1 of food waste and sludge is optimal for high-solids co-digestion.
- •
Cumulated free ammonia is the key risk threatening high-solids co-digestion.
