Abstract
Nastanak sve većih količina otpadnog mulja posljedica je izgradnje postrojenja za biološku obradu otpadnih voda. Svrha obrade mulja je smanjenje njegove količine i troškova zbrinjavanja. Anaerobnom digestijom se stabilizira otpadni mulj i proizvodi bioplin, obnovljivi izvor energije. U ovom radu je provedena karakterizacija otpadnog mulja nastalog aerobnom obradom farmaceutskih otpadnih voda. Kako bi se odredio potencijal dobivanja bioplina, provedeni su BMP testovi u omjerima inokulum/supstrat i kosupstrat od 0,1 do 3,0 pri 37 oC i 21 dan. Na temelju rezultata dobivenih BMP testovima, odabran je kosupstrat i omjer I/(S+KS) za proces anaerobne digestije. U pokusima je mjeren volumen bioplina, određivani su volumni udjeli metana, ugljikovog dioksida i dušika te je provedena fizikalno-kemijska i mikrobiološka analiza. Najučinkovitiji proces proveden je uz kosupstrat karton i omjer I1/(S+K)=1,0. Najveći volumen bioplina iznosio je 37,50 cm3, a najveći volumni udio metana iznosio je 45,84 %.
Abstract (english)
Construction of plants for biological treatment of wastewater results in increase in amount of sludge. The purpose of sludge treatment is to decrease its amount and the cost of storage. By anaerobic digestion the sludge is stabilized and biogas, a renewable source of energy, is produced. This paper characterizes the sludge which is obtained in the process of aerobic treatment of pharmaceutical wastewater. In order to determine the potential for obtaining biogas, BMP tests were conducted at the ratio inoculum/substrate and cosubstrate from 0.1 to 3.0 at 37 C and 21 days. Based on the results of the BMP tests, the cosubstrate has been chosen as well as the ratio I/(S+KS) for the process of anaerobic digestion. In the experiments the volume of biogas was measured, volume ratio of methane, carbon dioxide and nitrogen was determined, and physico-chemical and microbiological analyses were carried out. The most efficient process was carried out with the cosubstrate cardboard and the ratio I1/(S+K) = 1.0. The largest volume of biogas was 37.50 cm3 and the largest volume ratio of methane was 45.84%.
