投加生物促生剂、葡萄糖和氨基酸修复黑臭水体的效果

Study on Remediation of Black-odorous Water by Dosing Bio-energizer, Glucose and Amino Acid

在曝气条件下,投加生物促生剂BE、葡萄糖、氨基酸等物质,对南京南湖片区北河黑臭水体进行室内静态模拟修复试验。结果表明,3种物质对水体化学需氧量(COD)、氨氮、总氮去除效果明显,COD、氨氮、总氮去除率分别达到61.7%、76.6%、50.7%以上,水质指标由劣Ⅴ类提升为Ⅴ类标准,其中,投加BE去除效果最为明显;在不同温度[(15±2)℃和(25±2)℃]条件下,投加BE的修复效果表明,高温下黑臭水体修复效果明显好于低温条件下。

The indoor static simulation experiment on black-odorous water of north river in Nanhu District of Nanjing was carried on under the aeration conditions by adding bio-energizer BE, glucose, amino acids and other substances. The results showed that there were obvious eliminations of water COD,ammonia nitrogen and total nitrogen by rate of over 61.7%,76.6%, 50.7% respectively. The quality of water could reach grade V from inferior V according to the national standard for surface water. Among all these substances for elimination, BE was the most effective. Under the conditions of different temperatures [ （15±2）℃ and （25±2）℃], the result of a comparative test of dosing BE indicated that the elimination would be more effec- tive in high temperature than in low temperature.
