摘要/Abstract

摘要：研究了改性牡蛎壳粉处理生活污水的CODCr.当改性牡蛎壳粉的用量为7.5%、反应温度为25 ℃时，对CODCr和TP质量浓度分别为500，5 mg·L^-1，pH值为6.64的生活污水处理30 min，CODCr的去除率可达68.23%，对PO₃^-4—P的吸附量为0.043 1 mg·L^-1.研究结果说明改性牡蛎壳粉可用于生活污水的处理.

关键词： 生活污水, 改性牡蛎壳粉, CODCr

Abstract: Application of modified powder of oster shell to remove CODCr in waste water produced in life was investigated.Results showed that when the waste water (pH was 6.64) containing 500,5 mg·L^-1 of CODCr and TP was treated for 30 min at 25 ℃ using 7.5 g of modified powder of oster shell per 100 g waste water,68.3% of CODCr in waste water could be removed and the absorption amount of this powder to PO₃^-4—P reached 0.043 1 mg·L^-1 powder.It was feasible to treat wastewater produced in life using modified powder of oster shell.
