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 waste water is one of the pollution sources that has the most impact on ecological environment destruction in the water pollution of mining area in our country. The optimal growth conditions parameters of SRB determined by laboratory static experiment are temperature 35 ℃, pH 7.0, COD / SO42-ratio 1.3 , Fe2 + = 150 mg / L. Finally, using an internal anaerobic flow reactor (biofilm filter) type anaerobic bioreactor designed and developed by itself, the simultaneous removal of sulfur, nitrogen and phosphorus and the removal of heavy metal ions from acidic wastewater Feasibility studies and experiments show that this research idea and process design are feasible, and comprehensive treatment of wastewater can achieve satisfactory results.
