活性焦工艺处理难降解有机物的研究
|
Abstract:
通过小试试验、中试试验、工程项目生产实践开展了活性焦工艺去除难降解有机物的研究。结果表明，活性焦吸附COD为非均匀多分子层吸附，静态理论吸附量约199.45~260.65 mg COD/(g活性焦)。吸附柱设置形式对吸附效果略有影响，动态累积吸附量约为89.8 mg COD/(g活性焦)~96.0 mg COD/(g活性焦)。生产项目实践发现，活性焦应用于污水厂深度处理单元能够实现COD有效去除，出水水质达到污水厂排放标准要求。
The removal of Non-biodegradable organic matter by activated coke process was studied through small-scale, pilot-scale experiments and engineering practice. The results show that the adsorption of COD by activated coke is non-uniform multi-molecular layer adsorption, and the static theoretical adsorption capacity is about 199.45~260.65 mg COD/(g activated coke). The arrangement of adsorption column has a slight influence on the adsorption effect, and the dynamic cumulative adsorption amount is about 89.8 mg COD/(g active coke)~96.0 mg COD/(g active coke). The application of activated coke in advanced treatment unit of wastewater treatment plant can effectively remove COD, and the effluent quality can meet the discharge standard of wastewater treatment plant.
