Abstract
Aplicarea combinată a unor soluţii tehnologice noi, precum: stimularea chimică a metanogenezei, adaosul de compuşi
predecesori ai biosintezei vitaminei B12, recircularea CO2 şi suplimentarea acestuia cu H2, a condus la îmbogăţirea
sedimentelor epurării fermentativ-anaerobe a borhotului postdistilare alcoolică cu vitamina B12 de 1,5-2 ori. Drept rezultat,
a fost ridicată calitatea concentratului furajer vitaminizat, concomitent cu intensificarea producerii biometanului, astfel
mărind eficienţa ecologo-economică a epurării anaerobe a borhotului. O parte a cobalaminei se adsorbă pe particulele sedimentului
în procesul de formare a lui, iar o parte rămasă în soluţie se supune epurării avansate prin sorbţie pe sorbentul
mineral – diatomită. Produsul format poate fi utilizat în calitate de adaos furajer pentru animale şi păsări din agricultură.
The combined application of a series of new approaches, including chemical stimulation of methanogenesis, introduction of the compounds precursors of vitamin B12, recirculating of CO2 and adding of H2, have led to the 1,5-2 times enrichment with vitamin B12 of the sludge resulted from anaerob-digestive treatment of post-distillery vinasse. As a result, the quality improvement of vitaminized forage concentrate was reached, at the same time with the intensification of biomethane production, thus enhancing the ecologico-economic efficiency of the vinasse anaerobic treatment. A part of cobalamin is adsorbed on the particles of the forming sludge, whereas the remaining part is subjected to the advanced adsorption treatment on th mineral adsorbent – diatomite. The product formed can be used as a forage additive for cattle and poultry in agriculture.
