麦饭石固定化SRB污泥颗粒处理模拟煤矿酸性废水的适应性
Adaptability study on sludge particles of maifan stone immobilized SRB processing simulation acid coal mine drainage
摘要
Abstract
Aimed at studying the characteristics of heavy pollution and the high management cost of multicomponent acid coal mine drainage,the PVA-boric acid embedding cross-linking method was used to immobilize particles using sulfate reducing bacteria (SRB) and salt modified maifan stone.According to different hydraulic loading and pollution loading configure 3 groups dynamic column to undertake study on hydraulic conditions adaptability of immobilized particles.The results showed that the operation effect of immobilized particles was better under low hydraulic loading of 0.085 m3 · (m2 · d)-1 and a hydraulic retention time of 32.495 h.The removal rates of SO42-and Mn2+ were 65.90％ and 37.65％,respectively,while the effluent COD concentration was 635.06 mg · L-1,and TFe release amount was 4.03 mg · L-1,and the effluent pH was 6.94.After raising the concentration of the pollutants SO24-and Mn2 + to (2 657 ±96) mg · L-1 and (13.33 ± 1.75)mg · L-1,respectively,both SO42-and Mn2 + could still achieve removal rates of 40.07％ and 20.52％,respectively,while the effluent COD concentration was 64.07 mg · L-1 and TFe release amount was 2.69 mg · L-1;the effluent pH was 7.38.The immobilized particles had a better comprehensive processing effect,stronger adaptability to high concentrations of pollutants,and were better capable of resisting impact loads.关键词
