STUDY ON SLAUGHTERHOUSE WASTEWATER TREATMENT BY OXIDIZED/MEMBRANE FILTRATION PROCESS

In order to determine the suitable operating parameters of oxide /ceramic-ultrafiltration-membrane filtration technology of the treatment progress on the slaughter wastewater， the paper was about the influence of ClO2 dosage，backwash cycle and recoil time conditions on COD and turbidity． The experimental results showed that COD removal rate of oxidation unit was relatively high when ClO2 dosage was 140 mg /L，the COD and turbidity removal rate was over 93. 6%，95. 8% respectively and the permeation flux recovered better on the conditions of backwash cycle time of 50 min，backwashing time of 50 s． The quality of the produced water could meet the national discharge standard，and the total operation cost was low． This process had good prospects for industrial promotion．
