Rapid separation method of petroleum oil mud-water mixed liquor

Abstract

The invention discloses a rapid separation method of petroleum oil mud-water mixed liquor. The method includes the following steps that acid is added into petroleum oil mud-water mixed liquor at the room temperature to regulate the pH to be acidic, then flocculant is added, stirring is conducted for a reaction, and standing and filtering are conducted. Acidification and flocculation are adopted to achieve automatic solid-liquid separation of the petroleum oil mud-water mixed liquor, and the method has the advantages that solid-liquid separation is fast, treatment agents are cheap and easy to obtain, the disposal capacity is large, the technological process is simple, operability is high, and liquid clarity is high after treatment; besides, some waste acid can be recycled to deal with waste by waste, and thus the treatment concepts of resource conservation and energy conservation and environment protection are realized.

Description

technical field [0001] The invention belongs to the technical field of hazardous waste treatment, in particular to a method for rapid separation of petrochemical oil sludge water mixture. Background technique [0002] Petroleum is known as the blood of industry, mainly used as fuel oil and gasoline, and is also a raw material for many chemical industry products. Petrochemical oil sludge water mixture is the product of cleaning petrochemical oil storage tanks, mainly containing C5-C12 aliphatic hydrocarbons and naphthenes, complex hydrocarbons, long-term accumulated impurities, cleaning water, etc. The impurity mud, water and oil are uniformly mixed, the impurity mud is suspended in the liquid phase, and the calorific value distribution is uneven. The rate of solid-liquid separation by direct filtration is slow, and it cannot be directly incinerated by incineration. [0003] Petrochemical sludge-water mixture is a hazardous waste that has appeared in the petroleum industry i...

Problems solved by technology

The impurity mud, water and oil are uniformly mixed, the impurity mud is suspended in the liquid phase, and the calorific value distribution is uneven. The rate of solid-liquid separation by direct filtration is slow, and it cannot be directly incinerated by incineration.

[0003] Petrochemical sludge-water mixture is a hazardous waste that has appeared in the petroleum industry in recent years. At present, there is no reference material for the treatment of petrochemical sludge-water mixture. Most of the large amount of petrochemical sludge-water mixture produced by the petroleum industry is in a state of stockpiling , to be dealt with urgently
