淤泥消化 (sldge digestion): 在氧或无氧的条件下，利用微生物的作用，使淤泥中的 有机物转化为较稳定物质的过程。 好氧消化 (aerobic sigestion): 淤泥经过较长时间的曝气，其中一部分有机物由好氧 微生物进行降解和稳定的过程。 厌氧消化 (anaerobic digestion): 在无氧条件下，淤泥中的有机物由厌氧微生物进行 降解和稳定的过程。 中温消化 (mesophilic digestion ):淤泥在温度为33-530C时进行的厌氧消化工艺。 高温消化 (thermophilic digestion ):淤泥在温度为53-330C进行的厌氧消化工艺。 淤泥浓缩 (sludge thickening): 采用重力或气浮法降低淤泥含水量，使淤泥稠化的过 程。 淤泥淘洗 (elutriation of sludge ): 改善淤泥脱水性能的一种淤泥预处理方法。用清 水或废水淘洗淤泥，降低消化淤泥碱度，节省淤泥处理投药量，提高淤泥过滤脱水效 率。 泥脱水 (sludge dewatering ): 对浓缩淤泥进一步去除一部分含水量的过程，一般指 机械脱水。 淤泥真空过滤 (sludge vacuum filtration ): 利用真空使过滤介质一侧减压，造成介质 两侧压差，将淤泥水强制滤过介质的淤泥脱水方法。 淤泥压滤 (sludge pressure filtration ): 采用正压过滤，使淤泥水强制滤过介质的污 泥脱水方法。 淤泥干化 (sludge drying ): 通过渗滤或蒸发等作用，从淤泥中去除大部分含水量的过 程，一般指采用淤泥干化场（床）等自蒸发设施。 淤泥焚烧 (sludge incineration ):淤泥处理的一种工艺。它利用焚烧炉将脱水淤泥加 温干燥，再用高温氧化淤泥中的有机物，使淤泥成为少量灰烬。
Sludge digestion: The process of using microorganisms to convert organic matter in sludge into relatively stable substances under oxygen or anaerobic conditions. Aerobic digestion: The process in which sludge undergoes prolonged aeration, and some organic matter is degraded and stabilized by aerobic microorganisms. Anaerobic digestion: The process in which organic matter in sludge is degraded and stabilized by anaerobic microorganisms under anaerobic conditions. Mesophilic digestion: An anaerobic digestion process for sludge at a temperature of 33-530C. Thermophilic digestion: An anaerobic digestion process for sludge at a temperature of 53-330C. Sludge thickening: The process of using gravity or air flotation to reduce the moisture content of sludge and thicken it. Elution of sludge: A pre-treatment method for improving the dewatering performance of sludge. Wash the sludge with clean water or wastewater, reduce the alkalinity of the digested sludge, save the amount of sludge treatment chemicals, and improve the efficiency of sludge filtration and dehydration. Sludge dewatering: The process of further removing a portion of water content from concentrated sludge, generally referring to mechanical dewatering. Sludge vacuum filtration: A method of dewatering sludge by using vacuum to reduce pressure on one side of the filtering medium, causing a pressure difference between the two sides of the medium, and forcing the sludge water to filter through the medium. Mud pressure filtration: A method of sludge dewatering that uses positive pressure filtration to force the sludge water to filter through the medium. Sludge drying: The process of removing most of the water content from sludge through infiltration or evaporation, generally referring to the use of self evaporation facilities such as sludge drying fields (beds). Sludge incineration: A process for treating sludge. It uses an incinerator to heat and dry the dehydrated sludge, and then oxidizes the organic matter in the sludge at high temperature, making the sludge a small amount of ash.
