摘要

通过正交试验制备了以污泥为原料的活性炭,其BET比表面积为300.90 m2/g。研究了一种以活性炭为主要活性成分的新型脱氯剂。在200¿,3000 h-1空速,0.45~0.90 mm粒径,5120~5423 mg/m3输入浓度条件下,药剂的突破氯含量为19.38%,饱和氯含量为37.32%。本文还研究了空速、温度和粒径对吸附剂除氢性能和饱和曲线的影响。

Study on a New Dechlorinating Agent Based on Sewage Sludge
An activated carbon derived from sewage sludge was prepared by orthogonal test, and it had a BET surface area of 300.90 m2/g. A new dechlorinating agent using the activated carbon as the main active component was studied. The agent had a breakthrough chlorine content of 19.38% and a saturated chlorine content of 37.32% (under conditions of 200 ¿, 3000 h-1 space velocity, 0.45~0.90 mm particle size and 5120~5423 mg/m3 input concentration). The effects of space velocity, temperature and particle size on the HCl-removal behavior of the sorbent and the saturation curve ware also studied in this paper.
