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.

Key words: wastewater treatment, modified powder of oyster shell, CODCr
