| 摘 要： | 煤矸石和粉煤灰是煤矿区的两种主要废弃物,它们不仅占用大量的土地,同时也对矿区环境产生了严重污染。分别接种氧化硫硫杆菌和解磷细菌于煤矸石和粉煤灰中,通过柱状淋滤试验研究微生物对两种固体废弃物淋滤液污染性的影响。结果表明:煤矸石中添加氧化硫硫杆菌能显著脱除煤矸石中的硫,同时淋滤液中也生成了大量的H+和铁离子,使淋滤液中硫酸根和磷酸根离子浓度显著增大,超出了GB3838-2002《地表水环境质量标准》的指标。粉煤灰中添加解磷菌能显著提高淋滤液中的磷含量和电导率,但对淋滤液的pH、SO42-和铁离子影响不明显。氧化硫硫杆菌和解磷细菌对煤矸石和粉煤灰混合工艺处理效果较好,粉煤灰在一定程度上降低了硫、磷和铁的污染性。

| Abstract: | Coal waste and fly ash as two kinds of wastes in coal mining areas arouse not only land occupation but environment pollution.The role of microbes on different coal wastes was studied by inoculating Thiobacillus thiooxidans and phosphate solubilizing bacteria to coal waste and fly ash separately.Results showed that inoculating Thiobacillus thiooxidans to coal waste can significantly remove its sulfurs,produce a lot of H+ and iron ions and increase SO42-and PO43-in the leaching solution,which is beyond the st... |
