摘要
通过逐步提高有机负荷和盐浓度的方法 ,驯化出耐高浓度盐污泥 ,在进水NaCl浓度为( 2 6 8～ 4 72 )× 1 0 4mg·L- 1之间时 ,系统的单位污泥负荷较低 ,只有 0 32kgCOD·kgVSS- 1·d- 1,保持反应器较高的污泥浓度可使容积负荷达到 1 6kgCOD·m- 3·d- 1,COD和苯乙酸去除率可以达到95 %以上。驯化后的污泥能适应瞬时盐浓度变化冲击。
Active sludge tolerating high salinity industrial wastewater was acclimated in this study by increasing the organic loading rate and salinity concentration gradually.Under the influent NaCl (2.68～4.72)×104 mg·L-1,while keeping the system with a high sludge concentration,the reactor attained a organic volumetric loading rate of 1.6*!kgCOD·m-3·d-1though the sludge organic loading rate was low as 0.32*!kgCOD·kgVSS-1·d-1,and more than 95% of COD and phenyl acetic acid were removed.
