- Abstract
The investigation device - small size periodic operation bioreactors, which are developed for the production of biogas from different organic, vegetable waste. The device operates by maintaining optimum operating temperature and oxygen concentration required for anaerobic treatment process inside the bioreactor. Under favorable conditions, organic substance is being degradated because of anaerobic processess, colonies of microorganisms grow, and methane bacteria produce CH4 - useful flammable gases, which can be used as natural gas analogue. The gas is stored in special tanks of gas - gas holders. A study was implemented by analizing five different loads, according to the mixing ratio of vegetables (potatoes) and chicken manure waste. The quality and quantity of biogas was analized as well. It was found that the highest concentration of methane (67.8%) was achieved by using a load consisting only of chicken manure, but after evaluation of biogas yield, it was found that the best result (according to the quantity of biogas, a high concentration of CH4 and time of load degradation) is achieved using chicken manure and potato waste mix (relatively 70 and 30%). Mesophilic process temperature during the experiment was 33-35 °C, and oxygen concentration - 0.0-0.1%. After research implementation there will be an opportunity to create small size periodic operation bioreactors, which can be used in small farms or private houses, where the small amount of organic waste and manure are formed.
