一种利用高温干式厌氧消化处理脱水藻泥和秸秆混合物的装置
摘要：
本发明公开了一种利用高温干式厌氧消化处理脱水藻泥和秸秆混合物的装置，首先将脱水藻泥（或剩余污泥）、粉碎后的秸秆、回流接种污泥在物料混合池里面混合。之后送入主反应器里面发酵，反应器温度控制在55℃左右，固体停留时间12‑18天，反应器运行直至出料产气量低于2m3/（m3·d）。出料含水率80%‑85%,一部分作为接种污泥回用，大部分外运作为肥料利用。利用这种方法处理后VS降解率55%‑60%，单位体积产气量110 m3/（m3·d），甲烷含量平均55%。
摘要（英）：

The invention discloses a device for treating a dewatered algae ooze and straw mixture by utilizing high-temperature dry-type anaerobic digestion treatment. A treating method comprises the following steps: firstly, mixing dewatered algae ooze (or surplus sludge), smashed straw and re-inoculation sludge in a material bulking tank; feeding the obtained mixture to a main reactor, carrying out fermentation, wherein the temperature of the reactor is controlled to be about 55 DEG C, the solid standing time is 12-18 days, the reactor operates till the gas production rate of the discharged material is lower than 2m<3>/(m<3>.d), the water content of the discharged material is 80%-85%, one part of the discharged material is taken as inoculated sludge for recycling, and the most part of the discharged material is transported outwards to be taken as a fertilizer. After treatment by adopting the method, the VS degradation rate is 55%-60%, the gas production rate in unit volume is 110m<3>/(m<3>.d), and the average content of methane is 55%.
