摘要/Abstract

摘要：

以污泥发酵前后的残渣热解制备生物炭,考察发酵前后污泥生物炭的物理性能及其对氨氮、总磷的吸附能力。实验结果表明污泥发酵有利于生物炭孔隙结构的发展,污泥发酵后制备的生物炭(FSBC)比表面积、孔体积均高于未发酵污泥制备的生物炭(SBC)。吸附实验结果表明,对于磷酸盐的吸附,3种材料吸附能力大小为 FSBC > SBC > CAC,对于氨氮的吸附,吸附能力顺序为CAC > FSBC > SBC,污泥发酵后制备的生物炭对氨氮和总磷的吸附能力较未发酵污泥生物炭明显增强。对于实际废水中氮、磷的吸附,其去除率顺序均为CAC > FSBC > SBC,其中CAC和FSBC对总磷的去除率分别为31%和27%,对氨氮的去除率则分别为7%和4%。FSBC与CAC对总磷和氨氮的去除率相差不大。FSBC作为污泥资源化得到的低成本吸附剂,有广阔的研究前景。

Abstract:

The physical properties and adsorption capacity of unfermented sludge based biochar (SBC) and fermented sludge based biochar (FSBC) to ammonia and total phosphorus were investigated. Also, their adsorption capacities were compared with commercial activated carbon (CAC). The results indicated that the fermentation was favor of the development of pore structure, and the specific surface area and pore volume of FSBC were higher than that of SBC. The adsorption capacity of phosphate among three carbon materials was FSBC > SBC > CAC, indicating chemical adsorption is the major type for the phosphorous. For ammonia, the result was CAC > FSBC > SBC, suggesting that the adsorption is largely dependent on the physical adsorption. The FSBC adsorption capacity to ammonia and phosphorus was enhanced compared with SBC. When applied in the authentic wastewater, the removal sequence of ammonia and phosphorus was CAC > FSBC > SBC. The phosphorus removal efficiency by CAC and FSBC was 31% and 27%, respectively. And the ammonia removal efficiency by CAC and FSBC was 7% and 4%, respectively. The ammonia and total phosphorus adsorption capacities by FSBC were closed to CAC, which indicated that as a low cost product from the sewage sludge, FSBC was promising for the adsorption of ammonia nitrogen and phosphorus in the future research.
