污油泥处理技术设备技术

Sewage sludge treatment technology and equipment technology

1.热水洗处理法是指将污油泥、水以及学习化学药剂混合加热，将污油泥中的有机结合物质从土壤中脱离出来，最终经油水分离，实现中国原油市场资源的回收有效利用。目前污油泥处理技术设备厂家根据高含液污油泥的特性，主要研究采用不同化学热洗的工艺技术进行分析处理，并取得了一个良好的治理工作效果。

The method of hot water washing treatment refers to the mixing and heating of the oil sludge, water and learning chemicals, and the separation of the organic binding substances in the oil sludge from the soil, and finally the separation of oil and water, so as to realize the recovery and effective utilization of the crude oil market resources in China. At present, according to the characteristics of high liquid sewage sludge treatment equipment manufacturers, mainly study the use of different chemical hot washing technology for analysis and treatment, and has achieved a good treatment effect.

2.热解吸处理技术

Thermal desorption

热脱附方法在无氧环境中的方法，采取的污水污泥的形式间接加热的无害化处理，后处理系统的最终缩合期间产生的可达到的原油回收裂解气。污水污泥的低电流塔河油性液体的含量的特性，主要是热解吸过程进行处理，在处理2018约131000吨受浸污垢，油回收1120.8侧，取得了良好的环境和经济效益。

Thermal desorption methods in an oxygen-free environment, a method that takes the form of sewage sludge indirectly heated for harmless treatment, and a post-treatment system that produces recoverable crude oil recovery pyrolysis gas during the final condensation. The characteristics of the low-current tahe oily liquid content of sewage sludge are mainly thermal desorption process for treatment, in 2018 about 131,000 tons of soaked dirt, oil recovery 1120.8 side, achieved good environmental and economic benefits.

3 调质-机械进行分离处理信息技术

Tempering - Information technology for mechanical separation processing

调理和机械分离技术是指在污泥中加入一定量的化学药剂，改变污泥的理化性质，从而固液分离过程。 由于污油泥处理技术设备中原油含量在实际应用情况下相对较高，因此需要与处理后污泥的其他排放相结合。 同时，该技术必须配备水处理系统，否则容易造成水污染。

Conditioning and mechanical separation technology refers to the process of solid-liquid separation by adding a certain amount of chemical agents to sludge to change the physical and chemical properties of sludge. Since the crude oil content in the sludge treatment technology equipment is relatively high in practical application, it needs to be combined with other discharge of sludge after treatment. At the same time, the technology must be equipped with a water treatment system, otherwise it will easily cause water pollution.

4 溶剂萃取技术

Solvent extraction technique

溶剂提取技术是先用萃取剂萃取污泥，然后用蒸馏法将萃取剂从原油中分离出来，从而回收原油。溶剂提取具有原油采收率高、能耗低、二次污染少等优点，但由于超临界流体萃取大，难以大规模推广。

Solvent extraction technology is to extract sludge with an extractant, and then to separate the extractant from the crude oil by distillation, so as to recover the crude oil.
Solvent extraction has the advantages of high oil recovery, low energy consumption and less secondary pollution, but it is difficult to be widely used due to its large supercritical fluid extraction.

污油泥处理技术设备目前很多，但在实际应用过程中的优点和缺点，就目前而言，热解吸过程中有大规模处理污泥的方面一定的优势，但过程本身污水污泥的物理和化学的性质要求较高，它不能处理所有类型的污水污泥的，因此限制了其应用的范围。
Sewage sludge treatment technology and equipment at present a lot of, but in the advantages and disadvantages in the process of practical application, for now, the thermal desorption mass treatment sludge in the process of a certain advantage, but the process itself and chemical and physical properties of sewage sludge demand is higher, it can't handle all types of sewage sludge, thereby limiting the scope of its application.
