摘要: 针对混凝碳化污泥吸附对城市污水深度处理的实验研究，结果表明，由城市污水厂剩余污泥经脱水、干化和碳化后所制得的碳化污泥，可通过三氯化铁混凝碳化污泥吸附联合应用于城市污水深度处理中，处理效果明显优于仅使用碳化污泥吸附或单一采用三氯化铁絮凝剂混凝时的效果，出水各污染物指标可达到一级A标准(GB 18918-2002)，其最佳投药量为三氯化铁15 mg/L，碳化污泥5 g/L。

Abstract: This pilot study was designed to investigate advanced treatment of municipal wastewater using coagulation aided with adsorption on a sludge-derived-carbon. The sludge-derived-carbon was developed from sewage sludge’s dehydration， dryness and carbonization. The results show that the contaminants were more efficiently removed when the Ferric chloride coagulation was preceded by the sludge-derived-carbon adsorption than when the two processes were run separately. And the contaminants concentrations of the advanced treatment effluent satisfied the first level A criteria specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant， China (GB 18918-2002). The optimal dosages are determined as follows: 15 mg/L of ferric chloride， 5 g/L of Sludge-derived-carbon.
