Co-epuration of winery and pesticides effluents, activated sludge with tertiary nanofiltration, two new technologies for pesticides effluents treatment

摘要

Wine-related activities produce significant volumes of wastewater characterized by highnconcentrations in organic matter. The term of pesticides effluents defines the water comingnfrom the emptying and the rinsing of the equipment used to pulverize the phytosanitarynproducts on the vines. Pesticide pollution of surface waters from vineyards applicationsnrepresents a considerable hazard for the aquatic environment. The nature of these wastesnis very variable, indeed more than 150 active molecules can be employed. So, the mainncharacteristic of these effluents is their toxicity towards the environment. In this study, annapproach was developed to estimate the possibility of developing two biological wastewaterntreatment process for pesticides effluents treatment. The first one is particulary designed fornsmall vineyard and is a co-epuration process combining winery wastewater treatment withnpesticides effluents treatment. The second one is an activated sludge with tertiarynnanofiltration and is particulary suited for large vineyards or regroupings of wine growers.
