贵州凯里煤矿地区水质分析与微生物处理实验研究

分析贵州凯里地区煤矿排出废水对周边环境的危害,开展了生物法处理受污染河水的试验研究.对贵州凯里地区从鱼洞到江口的一段河流进行取样分析,通过测定色度、OD、SS、pH值及重金属元素浓度等指标,分析煤矿废水对当地生态环境的污染状况.利用硅酸盐细菌(Bacillus mucilaginosus)GY03菌株所产生的絮凝物质探讨其对煤矿废水的吸附作用和处理效果,结果表明,该絮凝剂对水样的最大絮凝率为97.94%,SS去除率达99.43%,对总铁、Zn2 和Ti4 的最大去除率分别为91.94%,90.93%和90%.这说明该絮凝剂能够有效改善受煤矿污染水体的水质.研究结果为微生物絮凝剂在煤矿废水治理中的应用提供了参考资料.

WATER QUALITY ANALYSIS AND MICROBIAL TREATMENT TO THE COLLIERY AREA OF KAILI IN GUIZHOU PROVINCE,CHINA

The hazard to the circumjacent ecological environment of a colliery area was analyzed in this paper,which was caused by the colliery wastewater of Kaili in Guizhou Province.By determining chromaticity,OD,SS,pH and element concentrations of heavy metals,water at sampling points from Yudong to Jiangkou at Kaili in Guizhou Province was analyzed,and the pollution to the local ecological environment,which was caused by collieries,was further studied.Moreover,the adsorption and treating effects were explored by the flocculants produced by the silicate bacterium(Bacillus mucilaginosus)GY03 strain.It was shown that the maximum flocculation ratio was 97.94%,the maximum SS removal ratio was 99.43%,and the maximum removal ratios was 91.94%,90.93%,and 90% for the total Fe,Zn2 ,and Ti4 ,respectively,which indicated that silicate bacterium GY03 could be used as an effective bio-flocculant to improve colliery wastewater.
