随着自然资源的消耗加快，一些废弃物的利用技术越来越被企业所关注，而在我国的自然资源短缺状况尤为严重。因此，大家也看到了其实一些废弃物的资源化利用研究在我国就显得更为重要。那么你知道污油泥处理的需要注意的事项?

With the accelerated consumption of natural resources, some waste utilization technologies are increasingly concerned by enterprises, and the shortage of natural resources in China is particularly serious. Therefore, we have also seen that recycling research of some wastes is more important in China. So you know the need to pay attention to the disposal of sludge?

　　在污油泥处理的同时，还产生“三污泥”。油泥是“三泥”的一部分，主要来自浮选产生的浮渣、回收污水油脱水产生的油泥、隔油池底部污泥的排放。当然，它是石油化工行业的主要污染源之一。除此之外，这里还需要知道的是，其炼油污水中含油污泥的含油量一般为4%~8%，水分为60%~99%，其余为固体物质如如泥土、沙子和微生物。胶团、悬浮物和絮凝剂的聚合物等。除了这些话，大家还需要知道的是，一般中小型炼油厂每年产生数万吨污泥。如果不进行处理，直接排放和积累到自然环境中，其中的有害物质和石油烃会随着雨水的侵蚀而严重污染土壤和环境。污油泥处理长期露天存放，许多低分子挥发性污染物会挥发到空气中，对大气造成污染。同时，污油泥处理在厌氧条件下会产生大量硫化氢，影响周围空气环境。甚至对人员安全构成威胁。

In the treatment of oil sludge, but also produce "three sludge". Oil sludge is a part of "three mud", which mainly comes from the scum produced by flotation, the oil sludge produced by the dewatering of recycled sewage oil, and the sludge discharged from the bottom of the grease trap. It is, of course, one of the main sources of pollution in the petrochemical industry. In addition, it is also necessary to know that the oil content of the oily sludge in the refinery sewage is generally 4%~8%, the water content is 60%~99%, and the rest is solid material such as soil, sand and microorganisms. Polymers of micelles, suspensions and flocculants, etc. In addition to these words, you need to know that the average small and medium-sized refinery produces tens of thousands of tons of sludge every year. If not treated, directly discharged and accumulated into the natural environment, the harmful substances and petroleum hydrocarbons will seriously pollute the soil and environment with the erosion of rain. Long term open storage of oil sludge treatment, many low molecular volatile pollutants will volatilize into the air, causing air pollution. At the same time, a large amount of hydrogen sulfide will be produced by sludge treatment under anaerobic conditions, which will affect the surrounding air environment. Even poses a threat to personnel safety.

　　污油泥处理的难点在于含油污泥是多介质混合物混合在一起形成相对稳定的悬浮液。油泥可先静置沉淀，分离油泥中的水分。在剩余的悬浮液中，这也主要是由于固体颗粒上附着有石油类物质，石油类物质具有较强的附着力，从而形成了较为稳定的混合液。除了这些话，大家需要知道的是，这种混合溶液采用静置沉降的方法处理效果很差。过去，许多设备尝试使用真空过滤机、板框压滤机和带式压滤机进行过滤。由于石油类物质的存在，特别是它们的高粘度，滤网和滤布很快就被堵塞了。污油泥处理量小，运行周期短，分离效果也很不理想。使用转鼓离心机对含油污泥进行脱水是一种能耗低、效果显着的方法。由于污油泥处理中存在石油类物质，形成的混合物相对稳定。通常，新生成的油泥中仍有一部分游离水。当然，这部分水可以通过自然静沉来分离，其体积一般占总体积的15%～40%，含油量较小。

The difficulty of oily sludge treatment lies in the fact that oily sludge is a mixture of multiple media to form a relatively stable suspension. The sludge can be settled to separate the water in the sludge. In the remaining suspension, this is mainly due to the solid particles attached to petroleum substances, petroleum substances have strong adhesion, thus forming a more stable mixture. In addition to these words, you need to know that this mixture of solutions by standing sedimentation method is very poor treatment. In the past, many devices tried to use vacuum filter, plate and frame filter press and belt filter press for filtration. Due to the presence of petroleum substances, especially their high viscosity, the screens and press cloths quickly become clogged. The waste oil sludge treatment capacity is small, the operation cycle is short, and the separation effect is not ideal. Using rotary centrifuge to dehydrate oily sludge is a method with low energy consumption and remarkable effect. Due to the presence of petroleum substances in the sludge treatment, the mixture formed is relatively stable. Usually, there is still some free water in the newly generated sludge. Of course, this water can be separated by natural sedimentation, and its volume generally accounts for 15% ~ 40% of the total volume, with a small oil content.

　　通过上述内容对介绍以后，我们也污油泥处理的需要注意的事项有了进一步的了解。以后再看到他的时候就不会感到陌生了，而且在使用的过程中也不会经常出现问题。好了，今天的内容就说到这里。

After the introduction of the above content, we also have a further understanding of the need to pay attention to the treatment of oil sludge. When I see him again, I will not feel strange, and I will not often have problems in the process of using him. Well, that's all for today.
