摘要

摘要: 由单项技术联用而形成的复合技术已被广泛应用于黑臭河道治理中。将膜曝气生物膜反应器(MABR)和微生物菌剂联用的复合微生物技术应用于小型黑臭河道实际治理工程中,结果表明:调试运行61 d,河道水体透明度、氧化还原电位(ORP)和溶解氧(DO)浓度上升,氨氮浓度和化学需氧量(COD)下降,但在调试运行期间水质存在反复现象;降水时水体透明度和ORP降低,氨氮浓度和COD反弹,雨后7 d均恢复正常,该技术有一定的抗冲击能力。稳定运行42 d后,河道的水体透明度、ORP和DO浓度分别提高了157%、57%和308%,氨氮浓度和COD降低了65.0%和71.4%,河道黑臭消除。该复合微生物技术消除河道黑臭的工程实际治理效果良好且系统能维持较长时间,但提高水质的能力有限,进一步提高河道水质还需通过系统化、生态化、智慧化的综合治理。

Abstract: The composite technology formed by the combination of single technologies has been widely used in the treatment of black and odorous rivers. A composite microbial technology combining membrane aerated biofilm reactor (MABR) and microbial inoculant was proposed and applied to the actual treatment on a small black odorous river. The results showed that after 61 days of commissioning, the transparency, ORP and DO concentration increased, the ammonia nitrogen concentrations and COD decreased, although the water quality repeated ups and downs during the commissioning operation. The Transparency and ORP dropped while ammonia nitrogen concentrations and COD rebounded during rains, and water quality returned to normal after 7 days, which meant that the composite technology had a certain impact resistance capacity. After 6 weeks of stable operation, the transparency, ORP and DO concentration of the river increased by 157%, 57% and 308%, respectively, and ammonia nitrogen concentrations and COD decreased by 65.0% and 71.4%, respectively, thus eliminating the black and odor of the river. This composite microbial technology presented a good effect on the engineering of eliminating the black and odor and the system could last for a long time, but the ability to improve the water quality was limited. To improve the river water quality to surface water environmental quality standards, the systematic, ecological and intelligent comprehensive control measures should be further promoted.
