Method for preparing ceramsite from oily sludge
The invention relates to a method for preparing ceramsite from oily sludge, which comprises the following steps: carrying out solid separation on the oily sludge to remove large-particle solids in the oily sludge; carrying out dehydration treatment until the water content is less than or equal to 70wt%, carrying out steam heating, adding distillate oil with the distillation range of 100-400 DEG C as a treating agent, carrying out a reaction, carrying out solid-liquid separation, drying the obtained solid, adding a cleaning agent, performing standing, separating out the solid, granulating, drying and roasting to obtain the ceramsite finished product. Under the synergistic effect of the distillate oil treating agent and the cleaning agent, the purpose of recovering the distillate oil in the oily sludge is achieved. The whole operation process is a closed loop, generated sump oil is recycled, generated solids are prepared into ceramsite with a high additional value, the recycling degree of the oily sludge is greatly improved, the added medicament is environment-friendly, the generated wastewater is low in salt content and simple to treat, and environmental pollution is not caused; the whole method does not involve high-temperature and high-pressure operation, and is economical and safe.
一种由含油污泥制备陶粒的方法，对含油污泥进行固体分离，将其中大颗粒固体物脱除；再进行脱水处理，使含水量≤70wt%，蒸汽加热，加入馏程为100‑400℃的馏分油作为处理剂，反应后，固液分离，对得到的固体进行干燥，加入清洗剂，静置，分出固体，造粒，干燥，焙烧后得到陶粒成品。本发明在馏分油处理剂和清洗剂的协同作用下，实现了回收含油污泥中馏分油的目的。整个操作流程均为闭环，产生的污油循环利用，产生的固体物制得高附加值的陶粒，大大提高的含油污泥的资源化程度，加入的药剂环境友好，产生的废水含盐量低，处理简单，不会造成环境污染；整个方法过程中未涉及高温、高压操作，经济安全。
