污油泥是指原油资源开采和集输过程中可以产生的油、水与泥土等混合形成的非均质多项分散体系，包括企业废水进行沉降油污泥、管线刺漏污染的油泥砂、联合站沉降罐油泥砂等。

Sewage sludge refers to the heterogeneous multi-dispersive system formed by the mixing of oil, water and soil in the process of exploitation and gathering and transportation of crude oil resources, including the settling oil sludge of enterprise wastewater, the oil sludge contaminated by pipeline leakage, and the settling tank oil sludge of joint stations.

污油泥处理方法以及分离机、离心机的作用:

Sewage sludge treatment method and the role of separator and centrifuge:

传统的污泥处理方法有直接填埋法(污泥直接埋入特殊的污泥贮存坑，然后填土，以恢复原有的景观，使污泥不会暴露在地面，减少对大气的影响)、注射法(污泥通过相应的钻孔设备注入底层，以达到减少污染的目的)、固化法(在污泥中加入一定量的固化剂，使固化剂与污泥固化处理)等，上述处理方法对污泥中的有害物质没有根本的处理作用。处理后的污泥一方面对土壤、地下水等具有潜在的风险，另一方面又会导致污油泥处理中石油资源的浪费。

Traditional sludge treatment methods have direct landfill method (sludge directly into specific sludge storage pit, and then fill, to restore the original landscape, make the sludge not exposed on the ground, to reduce the impact on the atmosphere), injection (sludge through corresponding drilling equipment into the bottom, in order to achieve the purpose of reducing pollution), curing method (add a certain amount of curing agent in the sludge, curing agent and the sludge solidification processing), etc., the processing method of harmful substances in the sludge is no fundamental role. On the one hand, the treated sludge has potential risks to soil and groundwater, and on the other hand, it will lead to the waste of petroleum resources in sewage sludge treatment.

污油泥的主要处理方式方法可以包括常温溶剂如分离机作为萃取、化学离心机热洗处理、焚烧垃圾处理、热裂解以及处理。常温溶剂萃取分析技术是指在常温环境条件下，采用不同溶剂系统进行物理深度分离，从而能够实现矿物油、乳泥浆化学剂等油基钻井液回收和油泥无害化处理工作过程；

The main treatment methods of oily sludge can include extraction with normal temperature solvent such as separator, chemical centrifuge hot washing treatment, incineration of waste, thermal cracking and treatment. Normal temperature solvent extraction and analysis technology refers to the process of using different solvent systems for physical depth separation under normal temperature environment, so as to realize oil based drilling fluid recovery and harmless treatment of oil sludge, such as mineral oil and emulsion mud chemical agent.

化学热洗处理是指通过化学药剂和热水共同放入离心机作用于含油污泥，使其粘度降低，实现油、水、固体三相分离的处理这个过程；焚烧处理是指在高温和富氧条件下，使含油污泥得到充分利用燃烧、彻底分解的过程；

Chemical hot washing treatment refers to the process of three-phase separation of oil, water and solid by putting chemical agents and hot water into a centrifuge and acting on oily sludge to reduce its viscosity. Incineration treatment refers to the process of making full use of oily sludge under high temperature and oxygen-enriched conditions for combustion and thorough decomposition.

污油泥热处理是指含油污泥在隔氧高温条件下，将油相经蒸馏、热分解、缩合等过程数据进行转化、分离与回收，最终目标实现城市污泥土地资源化、减量化、无害化的处理管理过程。

Sewage sludge heat treatment refers to the process of transforming, separating and recovering the oil phase data through distillation, thermal decomposition, condensation and other processes under the condition of oxygen isolation and high temperature, with the ultimate goal of realizing the resource utilization, reduction and harmless treatment and management process of urban sludge land.
