| 摘要: |
| 【目的】解决城市污水处理厂尾水排入河道引发的水体黑臭问题。【方法】在西安市某河道湿地内构建一封闭试验场，采用固定化微生物技术消除河道黑臭底泥和改善水质，为后续水生植物的修复和水质提升创造有利条件。【结果】经过3个月试验后，试验场内水体中CODCr、NH4+-N、TN、TP质量浓度基本可维持在22.0、5.0、11.5、1.7 mg/L左右，底泥的厚度减少50%左右，底泥颜色从黑色变成土黄色，底泥的生化降解能力增强。【结论】采用Ⅰ型和Ⅱ型固定化微生物协同技术可有效解决黑臭水体问题。 |

| Abstract: |
| 【Objective】 Solve the problem of polluted water caused by natural water shortage in western city and constantly discharging of WWTP tail water. 【Method】 A testing site was established in a river wetland of Xi’an, and the immobilized microorganism technology was used to eliminate the black and foul sediment and improve the water quality, which created favorable conditions for the subsequent restoration of aquatic plants and the promotion of water quality. 【Result】 The concentration of CODCr, NH4+-N, TN, TP in testing site maintained at 22.0 mg/L, 5.0 mg/L, 11.5 mg/L, 1.7 mg/L, the thickness of sediment was reduced by 50%, the color of sediment changed from black to khaki, and the biochemical degradation ability of sediment was enhanced after 3 months. 【Conclusion】 The combined use of type I and II immobilized microorganisms technology can effectively solve the problem of polluted water. |
