Micro-aerobic digestion was used to treat high-solid anaerobically digested sludge( ADS) further. Treatment performance and sludge 's phyto-toxicity improvement during the process were investigated at ambient,mesophilic and thermophilic condition. Results showed that high-solid anaerobically digested sludge achieved further stabilization,with further VS removal,SOUR reduction and lower content of VFA and ammonia nitrogen,under micro-aerobic condition of the aeration rate of 2. 4 L / min and SRT of 8 days.
