Preserved production is caused by wastewater pollution which has become a serious environmental problem in chaoshan district of one. Through the research KangHui group Chao’an cool fruit factory integrated nature of emissions from wastewater integrated wastewater, treat preserved fruits wastewater with activated sludge. In order to strengthen the cultivation of acclimation wastewater treatment, domestication was studied the best training domesticated aeration time. Experiments show that: The best treatment of preserved fruits wastewater is Acclimation of 38 h, and the wastewater CODcr removal rate reached 98.0%, then the effluent CODcr can be reduced in the 95 mg/L or so. Activated sludge treatment cool fruit production waste water, the training domesticated aeration and h of wastewater treatment after best effect.
