干法厌氧技术

Dry Anaerobic Technology

     干法厌氧技术是利用厌氧微生物的降解有机质产生沼气，通过燃气锅炉或热电联产回收利用热能，实现了有机固废的资源化利用。通过升温及搅拌等方式的创新，实现了发酵罐高含固率，相比传统湿法厌氧发酵，容积利用率提高2～3倍。发酵罐内含固率高达15－30%，而且将气体收集于发酵罐一体化，占地面积仅传统厌氧发酵的1/3～1/2，极大的降低了固定投资和运行成本；相比传统厌氧发酵，容许少量的塑料、砂石等杂质进罐，预处理简单，而且避免了浮渣和沉砂等因素导致无法稳定连续运行的问题；可应用于各种城市有机固废的协同处理，已广泛应用于城市污泥、餐厨垃圾、养殖固废的处理处置。实现规模化厌氧消化，回收可再生能源，打造生物质能源工厂。

Dry anaerobic technology is the use of biogas anaerobic microbial degradation of organic matter, by gas boiler or co-generation recycling heat energy, implements the resource utilization of sludge. By the innovation of heating and stirring methods, realized the high solid content, fermentation tank compared with the traditional wet anaerobic fermentation, capacity utilization by 2 ~ 3 times. Fermentation tank containing solid rate is as high as 15-30%, and the gas collected in integration of fermentation tank, covers an area of only the traditional anaerobic fermentation of 1/3 ~ 1/2, greatly reduce the fixed investment and operation cost. Compared with the traditional anaerobic fermentation to allow a small amount of impurities such as plastic, sａnd and gravel into the pot, simple pretreatment, and avoids the scum and grit and other factors cannot be stable and continuous running problem.Through many sewage treatment plant sludge concentration, and eat hutch garbage joint fermentation, realize large-scale anaerobic digestion, build a biomass power plant.
