| Abstract: | Pretreatment of wastewater from dimehypo production has been studied. Vaccum distillation was found to be a good choice to separate the salt from alkaline wastewater with the condition that the distillate could be treated by bio-methods directly, since its good biodegradability was about 1/3 of raw wastewater under vaccum tightness of 40KPa for 10 circulations, the removal of salts was up to 77%. For the mixture of acidic wastewater and wastewater absorbed exhaust gas, it could be achieved about 75%. Removal of CODcr and increment of BOD5/CODcr from 0.08 up to 0.36 by pH adjustment, 68% CODcr could be removed for pre-treated mixed wastewater by batch-biotreatment in 7 days. |
