| 摘 要： | 研究了光合细菌两段流化床正常启动运行后不同阶段淀粉降解微生物数量变化及污水最终的净化效果,并分离得到5株对淀粉降解非常明显的微生物菌株.结果表明,在好氧处理阶段,淀粉降解菌能够大量繁殖,能够与光合细菌共同完成污水降解作用,最终污水中的TN和NH3-N的平均降解率可分别达到91.2％和94.5％,CODCr的降解率为76.2％,TC降解率为41.0％,达到了污水净化的目的.

| Abstract: | Through study on the photosynthetic bacteria on both ends of the fluidized bed normal boot after running at different stages of starch degradation microbial quantity change and eventually the purification effect of the experimental research, and 5 strains were isolated from the microbial strains of starch degradation is very obvious. The results show that the aerobic treatment bacillus can multiply, and can complete the wastewater degradation together with the photosynthetic bacteria. Final total nitrogen and ammonia nitrogen in wastewater value of average deg- radation rate can reach 91.2% and 94.5% respectively. The degradation of CODcr is at a rate of 76.2%. TC degradation rate is 41.0%, a- chieving the purpose of sewage purification. |
