Mg~(2+)、Ca~(2+)对厌氧消化系统中CO_2的捕获和营养盐的回收
|
摘要
为探究矿物碳酸化与污泥厌氧消化耦合过程中实现CO_2捕获和N/P营养盐协同回收的可行性,在污泥水解液为底物的厌氧消化系统中,研究不同比例Mg~(2+)/Ca~(2+)离子添加对厌氧消化系统中CO_2捕获和营养盐的协同回收效果的影响.结果表明,添加Mg~(2+)/Ca~(2+)离子为(20mmol/L)/(0mmol/L)、(10mmol/L)/(10mmol/L)和(0mmol/L)/(20mmol/L)均可促进有机质降解,使沼气产量分别提升16.97%、21.56%和23.99%,并使CO_2含量由27.27%分别下降至24.81%,22.06%和21.98%.不同比例Mg~(2+)/Ca~(2+)离子添加可使磷酸根浓度下降63.46%～66.47%,但仅Mg~(2+)/Ca~(2+)离子以(20mmol/L)/(0mmol/L)和(10mmol/L)/(10mmol/L)添加的实验组中氨氮浓度得到下降.XRD分析揭示,Mg~(2+)/Ca~(2+)离子以(20mmol/L)/(0mmol/L)、(10mmol/L)/(10mmol/L)和(0mmol/L)/(20mmol/L)添加时分别使厌氧消化系统中形成鸟粪石和碳酸镁、鸟粪石和方解石、方解石和三斜磷钙石.Mg~(2+)、Ca~(2+)离子等摩尔量联合添加可实现最优的CO_2捕获和营养盐协同回收效果.
In order to explore the feasibility of simultaneous CO_2 sequestration and N/P nutrients recovery in sludge anaerobic digestion coupled with mineral carbonation,different ratios of Mg~(2+)/Ca~(2+)were added in the anaerobic digestion systems with sludge hydrolysate as substrate,to investigate the performance of simultaneous CO_2 sequestration and nutrients removal.The results showed that the addition of Mg~(2+)/Ca~(2+)of(20mmol/L)/(0mmol/L),(10mmol/L)/(10mmol/L)and(0mmol/L)/(20mmol/L)could promote the degradation of organic matters,so that the biogas production increased by 16.97%,21.56%and 23.99%,and the CO_2 content was reduced from 27.27%to 24.81%,22.06%and 21.98%,respectively.The phosphate concentration was reduced by 63.46%～66.47%with Mg~(2+)/Ca~(2+)addition of different ratios.However,ammonia nitrogen concentration was reduced only in the digesters with Mg~(2+)/Ca~(2+)added at(20mmol/L)/(0mmol/L)and(10mmol/L)/(10mmol/L).XRD analysis revealed that struvite and magnesium carbonate,struvite and calcite,calcite and monetite were respectively formed in the digesters with Mg~(2+)/Ca~(2+)added at(20mmol/L)/(0mmol/L),(10mmol/L)/(10mmol/L)and(0mmol/L)/(20mmol/L).The combined addition of Mg~(2+)/Ca~(2+)in equimolar amount achieved the best simultaneous CO_2 sequestration and N/P nutrients recovery.
