| 摘 要： | 采用中试规模的循环水养殖系统,对比研究碳源连续添加的微生物悬浮生长反应器(SGR-Con)和碳源分次添加反应器(SGR-Sev)的水处理效果。典型反应周期内的溶解性有机碳浓度变化,SGR-Con反应区处于较高的稳定水平,SGR-Sev在反应周期的第0小时至碳源瞬时添加时快速上升至SGR-Con的水平,并且在反应周期的第4小时以后降至较低的稳定水平。实验期间,SGR-Sev反应区和沉淀区的溶解氧含量分别显著高于SGRCon的反应区和沉淀区;2个反应器的反应区pH无显著差异,沉淀区pH在2个反应器之间亦无显著差异。碳源分次添加的方式显著提高了反应器的脱氮效果,SGR-Sev对硝氮和总氮的去除率、出水碱度分别可达63.91%±14.31%、64.07%±12.11%和(278.18±80.33)mg/L。相较于SGR-Con,SGR-Sev的出水总氨氮和亚硝氮浓度较高。反应器采用碳源分次添加的方式可使絮团具有良好的沉降性能。研究表明,微生物悬浮生长反应器宜采用碳源分次添加的方式。

| Abstract: | A suspended growth reactor under continuous carbon resource feeding method (SGR-Con) and another under several steps carbon resource feeding method (SGR-Sev) were operated in a pilot-scale recirculating aquaculture system to compare their water treatment efficiency. It indicated that the concentrations of dissolved organic carbon in the reaction zone of SGR-Con was at a high and stable level, while that in SGR-Sev firstly increased to the same level of SGR-Con during the 0 h in cycle to the instantaneously carbon feeding time and it subsequently decreased to a lower and stable level after 4 h in cycle. Dissolved oxygen in the reaction zone of SGR-Sev, as well as the settling zone was significantly higher than that in SGR-Con. The pH in the reaction zone between different reactors had no significant difference, and it was same in settling zone. Several steps carbon resource feeding method significantly increased the nitrogen removal of reactor. Overall the experimental period, the removal rate of nitrate and total nitrogen in SGR-Sev could be 63.91%±14.31% and 64.07%±12.11%, respectively. Besides, alkalinity in the effluent of SGR-Sev was (278.18±80.33) mg/L. SGR-Sev was favorable to achieve good settling performance of bio-flocs. However, the concentrations of total ammonia nitrogen and nitrite in the effluent of SGR-Sev were higher than those of SGR-Con. In summary, it is better to adopt the several steps carbon resource feeding method for suspended growth reactors. |
