Abstract
Au fost elaborate o tehnologie ecologic pură şi un bioreactor integrat intensiv de nouă generaţie pentru producerea biogazului prin valorificarea deşeurilor agroindustriale periculoase pentru mediul natural. S-a dezvoltat o tehnologie eficientă, independentă de sursa de alimentare centralizată, sporind astfel fiabilitatea şi eficienţa costurilor aprovizionării cu energie în zonele rurale. Procesul propus este uşor de gestionat, ecologic şi acceptabil pentru populaţie. Această tehnologie este unică în lume şi se bazează pe utilizarea fito-catalizatorilor naturali introduşi în biomasa fermentată în micro-concentraţii. Ei sunt obţinuţi prin extracţie din materii prime vegetale naturale şi deşeuri. Conţinutul biometanului în biogaz a crescut de la 62%, cu o valoare calorica de 5 232 kcal/m3, până la 85-92%, cu o valoare calorica de 8 010 kcal/m3. În plus, reziduurile de biomasă stabilizate pot fi utilizate ca îngrăşăminte organice, în timp ce apa tratată este conformă cerinţelor pentru irigare. Tehnologia asigură generarea energiei regenerabile „verzi”, atât electrice, cât şi termice, şi contribuie la îmbunătăţirea securităţii energetice şi ecologice în conformitate cu standardele naţionale şi internaţionale existente.
A new-generation intensive ecological technology and integrated bioreactor for biogas production were developed, based on the valorisation of agro-industrial wastes, hazardous for the natural environment. The efficient technology independent from centralized power supply was elaborated, which makes it possible to enhance the reliability and cost efficiency of energy supply in rural areas. An easily manageable technology proposed is environmentally friendly and an acceptable method beneficial for the population. This technology bears a breakthrough character and is based on the use of natural phyto-catalysts introduced into the digested biomass in micro-concentrations. They are obtained by extraction from natural vegetable feedstock and wastes. Biomethane contents in biogas is thus increased from 62% with a caloric value of 5 232 kcal/m3 to 85-92% with a caloric value of 8 010 kcal/m3. In addition, the stabilized biomass residues can be used as organic fertilizers, whereas the treated water meets the requirements for irrigation scopes. The technology ensures the generation of a renewable “green” heat and electric energy, and contributes to the improvement of energy and environmental security in accordance with the existing national and international standards. Keywords: biomass, phyto-catalysts, biogas, agro-industrial wastes, biomethane purification.
