Thermophilic Solid-state Anaerobic Digestion Of Surplus Waste Sludge

With the expanding of the livestock breeding, the increasing amount of excesssludge and antibiotic drug dosage, which results in the environmental problems thathave become increasingly prominent. Meanwhile, with the development of society,the problem of the shortage of energy has also been increasingly serious. In this paper,I employ the feature that solid sludge can be in thermophilic anaerobic digestion totreat excess sludge and study how sodium sulfa quinoxaline morpholine in antibioticdrugs has effect on the performance of producing the gas in anaerobic digestion inhigh temperature. I utilize solar water heaters to convert solar energy as heat so thatthe heat can provide heat that is needed in process of thermophilic anaerobic digestionand explore the practicality of that. Specific conclusions are as follows:(1) The experimental results in digestive gas and digestive liquid in process ofthermophilic anaerobic digestion suggests that the digestive liquid plays a good role ingas production and methane content, but has no obvious effect in deaminase forbiogas processing gas production and methane content. Explores the process ofdigestion of wheat straw degradation by SEM analysis.(2) The anaerobic digestion system works stable using the heat that solar waterheaters provide. The thermal energy that solar water heaters convert solar energy intocan be provided as heat in thermophilic anaerobic digestion, which is economicallyfeasible. The system itself is producing power consumption accounts for about7.99%of the calorific value of the gas, there is some value in engineering applications.(3) Sulfaquinoxaline sodium has an inhibition in the performance of producinggas in process of solid sludge thermophilic anaerobic digestion, and with increasingconcentration, it becomes more obvious.
