Abstract
Inventia se refera la un procedeu combinat de tratare a sedimentului, obtinut la fermentarea anaeroba a apelor reziduale si poate fi utilizata in industriile vinicola si alimentara la tratarea si utilizarea deseurilor. Procedeul include utilizarea in calitate de coagulant a defecatului, care se formeaza la tratarea extractelor zaharoase cu var, incantitate de 50...100% de la masa sedimentului uscat, cu aducerea amestecului obtinut pana la un pH7,5…8,5, agitarea timp de 30…60 min, sedimentareatimp de 1…2 ore, cu decantarea ulterioara, apoi sedimentul se trateaza cu un floculant, si anume cusolutie de poliacrilamida de 0,2…0,5% in cantitate de 50...100 mg/dm3 prin introducerea ei treptatade 2…3 ori, in cantitate de (0,50...0,60):(0,20...0,50):(0,20...0,25) corespunzator, dupa care lichidul se elimina si sedimentul se deshidrateaza prin compresie.The invention relates to a combined process of sediment treatment, obtained by anaerobic fermentation of wastewater and can be used in the wine and food industries to treat and use waste. The process includes the use as a coagulant of the defecate, which is formed in the treatment of sugary extracts with lime, incantation of 50 ... 100% from the mass of the dry sediment, with the mixture obtained up to a pH 7.5 ... 8.5, stirring for 30… 60 min, sedimentation for 1… 2 hours, with subsequent settling, then the sediment is treated with a flocculant, namely 0.2… 0.5% polyacrylamide suture in 50… 100 mg / dm3 by introducing it gradually 2 ... 3 times, in the amount of (0,50 ... 0,60) :( 0,20 ... 0,50) :( 0,20 ... 0,25) corresponding, after which the liquid is removed and the sediment is dehydrated by compression.
