【Abstract】 The biological contact oxidation process had been used in the treatment of lithoprinting waste water .The actual treatment effect of the process could only achieve a half of the designed efficiency.After carrying out the biodegradability test for the wastewater and comparison experiment on two biological treatment processes,it was decided to modify the existing process to hydrolytic acidification-contact oxidation process.The final effluent from the modified process could meet the discharge standards.更多还原
