- Аннотация: Sewage sludge, lawn maintenance waste, fruit/vegetable waste and food catering waste were chosen for study as typical municipal biological wastes. Hydrothermal pretreatment was used to accelerate biological anaerobic digestion for enhancement of biogas/bio-methane production from tested biowastes. Mesophilic anaerobic digestion tests were used to evaluate biogas production for original raw materials and hydrothermal treated biowastes. Laboratory batch biogasification tests were performed in duplicate with use of 3-liter glass anaerobic fermenters containing approximately 2 L of fermentation medium. The biogasification tests were conducted at a temperature of 37 ± 1 °C and stirred for 15 minutes every 2 hours. In the case of raw materials, fruit/vegetable waste and food catering waste show higher biogas/methane production than that of lawn maintenance waste and sewage sludge. After hydrothermal pretreatment at typical condition (160 °C at 0.5 h), the biogas (bio-methane) specific yields of fruit/vegetable waste, lawn maintenance waste and municipal sewage sludge increased by 7.6 (6.6), 26.5 (24.1) and 58.3 (53.2) % respectively, while for treated food catering waste the biogas (biomethane) specific yield decreased by 4.2 (6.1) %. It seems, the lower the origin waste biodegradability, the higher the biogas/bio-methane yield increasing after pretreatment. More detailed research on this topic is desirable.
