摘要
硫酸盐酸性矿山废水是我国矿区水污染中对生态环境破坏影响最大的污染源之一,通过实验室静态实验确定高效SRB最佳生长条件参数为温度35℃,pH 7.0,COD/SO42-比值为1.3,Fe2+=150 mg/L。最后,利用自行设计、研制的内升流(流化床)外降流(生物膜滤池)式厌氧生物反应器进行同步除硫、脱氮、除磷、去除重金属离子酸性废水综合治理的可行性研究,实验表明这一研究思路和工艺设计是可行性的,废水综合处理可达到较为满意的效果。
Sulfate acid mine wastewater is one of the biggest pollution sources to ecological environment influence in mining area of our country.Through laboratory static experiment the best growth condition parameters of SRB are determined: the temperature is 35℃,pH is 7.0,COD/SO42-is 1.3,Fe2+ is 150mg/L.Finally,by using the self-design,development/flow(fluidized bed) within the drop flow(biofilm term) type anaerobic biological reactor the paper carried out the feasibility study to synchronize desulfurazation and nitrogen,phosphorus removal,remove heavy metal ions acid wastewater of comprehensive treatment.The experiment showed that this research ideas and process design is feasible,wastewater comprehensive treatment can achieve a more satisfactory effect.
