Abstract
Granulirani mulj je samoimobilizirano mikrobno udruženje koje se primjenjuje u obradi otpadnih voda. Aerobne granule su sfernog ili eliptičnog oblika prosječne veličine promjera izmeĎu 0,2 i 9,0 mm. Karakterizira ih izvrsna taloživost i veliko zadržavanje biomase. Izvanstanične polimerne tvari pridonose strukturnoj stabilnosti aerobnih granula. To su organske makromolekule koje luče mikroorganizmi i tvore trodimenzionalnu matricu u koju se bakterije mogu ugraditi. Aerobni granulirani mulj omogućuje istovremenu nitrifikaciju, denitrifikaciju i uklanjanje fosfora u jednom reaktoru. Istraživanja primjene aerobnog granuliranog mulja provode se u sekvecnijalnom šaržnom reaktoru (SBR, engl. Sequencing Batch Reactor). Na formiranje i stabilnost aerobnih granula utječe brzina strujanja zraka, trajanje perioda gladovanja, temperatura, duljina vremena skladištenja, značajke mulja, metali, otopljeni kisik, organsko opterećenje, sastav otpadnih voda i drugi čimbenici. Aerobni granulirani mulj izvrsna je alternativa aktivnom mulju.
Abstract (english)
Granulated sludge is a self-immobilized microbial association used in wastewater treatment. Aerobic granules are spherical or elliptical with an average size diameter between 0.2 and 9.0 mm. They are characterized by excellent settling properties and high biomass retention. Extracellular polymeric substances contribute to the structural stability of aerobic granules. These are organic macromolecules secreted by microorganisms and form a three-dimensional matrix into which bacteria can be incorporated. Aerobic granular sludge enables simultaneous nitrification, denitrification and phosphorus removal in one reactor. Investigations of the application of aerobic granular sludge are carried out in a sequencing batch reactor (SBR). The formation and stability of aerobic granules are influenced by air flow rate, duration of starvation period, temperature, length of storage time, characteristics of sludge, metals, dissolved oxygen, organic load, wastewater composition and other factors. Aerobic granular sludge is an excellent alternative to activated sludge.
