摘要
从中原油田现场取样的污水中培养出的硫酸盐还原菌(简称SRB),可在聚合物驱油中生长繁殖并使水解聚丙烯酰胺(HPAM)发生降解;当接种的菌量为3.6×104个/mL时,经恒温30℃7天的培养,1000mg/L的HPAM溶液的粘度损失率可达19.6%。研究表明,菌体接种量的大小、溶液的pH值及SRB在HPAM溶液中的连续活化次数对HPAM的降解都有影响。
Sulfate reducing bacteria cultured from the waste water of Zhongyuan Oil Field can be grown in partially hydrolyzed polyacrylamide (HPAM) and be degraded. When the inoculated bacteria number was 3.6×10 4 N/mL, the viscosity loss of 1 000 mg/L HPAM solution can reach 19.6% after 7 day cultivation under 30 ℃. Further experimental results showed that the inoculating bacteria number, pH of HPAM solution and the continuative activating times all affected the degradation of HPAM.
