反硝化除磷颗粒污泥的活性恢复及对生活污水处理能力
Activity recovery and wastewater treatment ability of denitrifying phosphorus accumulating organism granules
摘要
Abstract
A sequencing batch reactor（SBR） was used to study the performance of physical activities and wastewater treatment ability during reactivation period after 1-month storage.Results showed that after storage the granular sludge colour became dark.But the granular appearance became brownish-yellow after 11 days of reactor restart period.Also,when SBR system was restarted,the granular sludge was still able to retain good ability after short-time storage.COD,NH＋4-N,PO3-4-P removal ability was fully reactivated after 14 d,40 d and 40 d,respectively.DNPAOs were reactivated after 50 d.Wastewater treatment experiment indicated that microorganism can not grow well when C/N 5.1,additional carbon sources were used in this experiment and proportion of real wastewater was kept at 60%.关键词
