干法厭氧技術

Dry Anaerobic Technology

     干法厭氧技術是利用厭氧微生物的降解有機質產生沼氣，通過燃氣鍋爐或熱電聯(lián)產回收利用熱能，實現(xiàn)了有機固廢的資源化利用。通過升溫及攪拌等方式的創(chuàng)新，實現(xiàn)了發(fā)酵罐高含固率，相比傳統(tǒng)濕法厭氧發(fā)酵，容積利用率提高2～3倍。發(fā)酵罐內含固率高達15－30%，而且將氣體收集于發(fā)酵罐一體化，占地面積僅傳統(tǒng)厭氧發(fā)酵的1/3～1/2，極大的降低了固定投資和運行成本；相比傳統(tǒng)厭氧發(fā)酵，容許少量的塑料、砂石等雜質進罐，預處理簡單，而且避免了浮渣和沉砂等因素導致無法穩(wěn)定連續(xù)運行的問題；可應用于各種城市有機固廢的協(xié)同處理，已廣泛應用于城市污泥、餐廚垃圾、養(yǎng)殖固廢的處理處置。實現(xiàn)規(guī)?；瘏捬跸?，回收可再生能源，打造生物質能源工廠。

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.
