Application of Bio-Char from Sewage Sludge Pyrolysis
To promote engineering application of municipal sludge pyrolysis technology and reduce economic cost of sludge pyrolysis operation, the paper discussed the feasibility of sludge-based char application in three aspects: sewage adsorbent, fuel and soil improving agent. Conclusion: the sludge-based char on SCOD adsorption time in the 30min reaches saturation, the SCOD removal rate above 30%; the removal rate of sludge-carbon on A/O reactor effluent COD have less effect, but there are certain effect on nitrogen removal; the sludge-based char can be burned at 400°C, release a lot of heat, it can be used as a low-grade fuel; the sludge-based char can promote plants growth, and has a good safety performance, may be used as a good soil improving agent.
