In order to find a more effective formula for sludge conditioning agents and clarify the dewatering characteristics of sludge when Fenton is combined with other agents,Fenton alone,Fenton and quicklime,Fenton and fly ash,and Fenton and PAM were used to condition sludge separately,and the effects of different conditioning agent ratios on sludge dewatering performance were explored.When the dosage of Fe2+and H2O2 was 40 mg/g DS,Fenton conditioned achieved the best dewatering performance.Fenton combined with quicklime or PAM conditioning improved the sludge dewatering capacity.The combination of Fenton and fly ash had no obvious effect on the dewatering performance of sludge.
