一种利用发酵型产酸菌处理高温蒸汽热水解污泥的方法
摘要：
本发明公开一种利用发酵型产酸菌处理高温蒸汽热水解污泥的方法，属于微生物应用领域。本发明步骤如下：(1)发酵型产酸菌的筛选；(2)发酵型产酸菌纯培养；(3)厌氧消化：按照发酵型产酸菌与高温蒸汽热水解污泥的体积比为1:8的投加量，利用发酵型产酸菌处理高温蒸汽热水解污泥，处理温度为50℃，周期18d；(4)沼气收集，消化后污泥进行堆肥处置。本发明利用微生物方法处理高温蒸汽热水解污泥，相比于热水解后污泥直接高温厌氧消化处理，COD的去除率提高了20％～25％，产气量提升了90％～95％，本发明具有处理效率高，反应周期短，同时产生的沼气可以综合运用，真正地实现污泥的无害化、减量化、无害化处理。
摘要（英）：

The invention discloses a method for treating high-temperature steam thermo-hydrolyzed sludge through fermentation type acid-forming bacteria, belonging to the field of microbe application. The method comprises the following steps: (1) screening the fermentation type acid-forming bacteria; (2) purely culturing the fermentation type acid-forming bacteria; (3) performing anaerobic digestion: according to the dosage of the fermentation type acid-forming bacteria to the high-temperature steam thermo-hydrolyzed sludge being 1 to 8 by volume, using the fermentation type acid-forming bacteria to treat the high-temperature steam thermo-hydrolyzed sludge, wherein the treatment temperature is 50 DEG C and the period is 18d; (4) performing methane collection for compost treatment on digested sludge. According to the method provided by the invention, a microbiologic method is used for treating the high-temperature steam thermo-hydrolyzed sludge, compared with direct high-temperature anaerobic digestion treatment on the thermo-hydrolyzed sludge, the removal rate of COD is improved by 20 to 25 percent, and the gas production rate is improved by 90 to 95 percent. The method provided by the invention has the advantages that the treating efficiency is high, the reaction period is short, meanwhile, generated methane can be comprehensively used, and real harmless reduction treatment on the sludge is realized.
