摘要
用ERIC-PCR指纹图谱监测制药综合废水活性污泥生态系统,结合活性污泥性质测定和理化指标监测结果,综合评价处理系统运行状态.4个时间点的监测中,受高盐影响污泥沉降比和污泥指数略微偏高,第1监测时间最高分别为68%和282.93 mL/g,第4监测时间最低分别为39%和187.64 mL/g;CODCr去除率在73.23%～86.73%之间;ERIC-PCR指纹图谱的多样性指数稳定在2.24～2.38之间,相似性指数差异较大,最高为95%,最低为19%.表明第1监测时间高负荷冲击会导致系统CODCr去除率下降,第2监测时间短时期缺氧不会影响系统正常运行,第3、4监测时间水质水量稳定活性污泥处理系统微生物种群结构和处理效率稳定.
The occurrence, settleability and activity of sludge in a treatment system of medicine wastewater from pharmaceuticals production were estimate by ERIC -PCR （Enterbacterial Repetitive Intergenic Consensus - PCR） fingerprinting combined with activated sludge characterization （ SV30, SVI） and CODer measurements. During the monitoring period, high - sanlinity wastewater caused SV30 and SVI appreciably higher than natural level,the highest at M1 with 68%and 282. 93mL/g and lowest at M4 with 39%andl 87.64ml/g, the removal efficiency of CODer fluctuated from 73.23% to 86.73%. ERIC - PCR banding patterns of activated sludge samples were fairly stable between 2.24 and 2.38 for Shannon - weaver indices, and greatly fluctuant from 19% between M1 and M2 to 95% between M3 and M4. The results indicate that the presence of a pollution shock causes low removal efficiency of CODer at M1, short - time anxic condition doesit impact treatment system of wasterwater at M2 ,and stabilization of wastewater quality and quantity serve as the relatively stable removal efficiency of CODer and microbial community of activated sludge between M3 and M4.
