摘要
气田污水在污水罐、污水池中沉淀的污泥由于含有部分甲醇、油分等物质,按照安全环保要求,需要经过专门的设备处理后,降低其含水率,才能进行后续处理。目前国内传统带式脱水机、板框式脱水机、干燥脱水机等脱水设备处理后泥饼含水率在75%～85%之间,需要进行二次干燥处理,而新型的脱水设备螺压脱水机处理后泥饼含水率可达到60%,不需要后续处理,能够满足污泥处理生产需要。
Precipitation of sludge in sewage tank and sewage pond contains some methanol, oil and some other materials on gas field. In accordance with the requirements of environmental safety, the need for specialized equipment reduces the moisture content of the sludge,then finishing the follow-up processing. At present, the moisture content of the sludge after processing by traditional belt hgdroetractor, frame- hgdroetractor and drying hgdroetractor is in the 75 %-85 % which needs second dried processing.While the moisture content of the sludge after processing by screw press hgdroetraetor can be achieved to 60 % which doesn＇t need second dried processing and meets production needs in sludge processing.
