| 摘 要： | 利用分离培养基从草坪、芦苇地、公园以及菜园土壤中分离到一株高效钾细菌菌株,经纯化后,研究了钾细菌对铜的耐受阈值,并筛选了提高钾细菌Cu^2＋耐受阈的钝化剂。结果表明,钾细菌最高能耐受Cu^2＋的浓度为50mg/L。投加钝化剂粉煤灰和石灰后,钾细菌对Cu^2＋的耐受阈提高到80mg/L,粉煤灰对重金属铜的钝化性能优于石灰。

| Abstract: | An efficient strain of potassium bacteria is isolated from grass,reed,soil in the park and garden through isolation medium.After being purified,the potassium bacteria＇s tolerance threshold for Cu^2＋ and the screening of passivation agent used to improve the tolerance ability for Cu^2＋are studied.The results show that the highest Cu^2＋ concentration that potassium bacteria can withstand is 50mg/L.By adding passivation agent such as fly ash and lime,the threshold of potassium bacteria＇s tolerance for Cu^2＋ can be increased to 80mg/L,and the fly ash＇s passivation effect is better than lime. |

| Keywords: | potassium bacteria separation copper ion threshold of tolerance passivation agent |
