摘要:
膜浓缩液的处理是当前膜技术处理垃圾渗滤液亟待解决的瓶颈.将污水处理后的剩余污泥热解制成污泥基生物炭(SBB),用于吸附膜浓缩液.脱水污泥碳化后的污泥基生物炭呈现多孔结构,孔径大幅减小,比表面积和总孔体积增大,首次再生炭(RSBB1)比SBB的COD吸附效果可提高1.88倍,达到84.06%; 吸附饱和的污泥基生物炭可多次再生重复利用,再生3次COD的去除率仍然达到80%以上.
Abstract:
The membrane concentrate treatment is a bottleneck that needs to be solved in thecurrent membrane technology for the waste leachate treatment. In this paper, sludge-basedbiochar(SBB)was pyrolyzed from the residual sludge after wastewater treatment for theadsorption of membrane concentrate. The sludge-based biochar after carbonization ofdewatered sludge showed a porous structure with greatly reduced pore size, increasedspecific surface area and total pore volume, and the COD adsorption effect of the firstregenerated carbon(RSBB1)was 1.88 times higher than that of SBB, reaching 84.06%; moreover, the adsorption saturated sludge-based biochar could be regenerated and reusedseveral times, and the COD removal rate was still over 80% after three regenerations.Thisstudy provided a preliminary experimental basis and theoretical reference for the recyclingof urban solid waste.
