Description
Technical field
The invention belongs to hazardous waste processing technology field, more particularly to a kind of petrochemical industry greasy filth water mixed liquid quick separating
Method.
Background technology
Oil is referred to as the blood of industry, is mainly used as fuel oil and gasoline, is also many chemical industries
Raw material.Petrochemical industry greasy filth water mixed liquid is the product for cleaning petrochemical industry oil tank, mainly contain C5~C12 aliphatic hydrocarbons and cycloalkane,
Impurity mud, water for cleaning of complicated hydro carbons and long term accumulation etc..Its impurity mud, water, oily three uniformly mix, and impurity mud hangs
Floating calorific value skewness, directly filtering carry out separation of solid and liquid speed slowly in the liquid phase, also can not be direct using burning mode
Carry out burning disposal.
Petrochemical industry greasy filth water mixed liquid is the hazardous waste that petroleum industry occurs in recent years, mixed for petrochemical industry greasy filth water at present
The processing for closing liquid there is no the data referred to, and the substantial amounts of petrochemical industry greasy filth water mixed liquid that petroleum industry is produced, which is mostly in, to be stored up
State, it would be highly desirable to handle.
Make petrochemical industry greasy filth water mixed liquid carry out solid-liquid using acidifying flocculation voluntarily to separate, be easy to get with treatment agent is cheap,
Processing cost is relatively low, and disposal amount is big, and technological process is simple, the advantages of workable, and can carry out resource to some spent acid
Change and recycle the treatment of wastes with processes of wastes against one another, realize the processing theory of resources conservation and energy-conserving and environment-protective.
The content of the invention
It is an object of the invention to provide a kind of method of petrochemical industry greasy filth water mixed liquid quick separating, this method can make petrochemical industry oil
Muddy water mixed solution is fast and effeciently separated.
The technical proposal of the invention is realized in this way：A kind of method of petrochemical industry greasy filth water mixed liquid quick separating, including
Following steps：At ambient temperature, acid, acidification reaction are added into petrochemical industry greasy filth water mixed liquid, regulation pH is acidity；Then again
Flocculant is added, flocculation stirring reaction stands filtering.
In the present invention, acid is added, regulation pH is acidity, the water and oil in oil-water mixture are made due to hydrionic hydrophily
Mud is separated；Adding the huge adsorption effect of flocculant generation makes to form bigger flco between particle, so that greasy filth and water
Separation.
Preferably, the acid is nitric acid, its mass concentration is 2%~15%；
Preferably, the pH, which is more than or equal to 1, is less than or equal to 3；
Preferably, the acidificatoin time is 5~30 minutes；
Preferably, the flocculant is polyacrylamide（PAM）, its addition is hundred a ten thousandths to 10/10000ths；
Preferably, the time of the flocculation reaction is 30~120 minutes.
The beneficial effects of the present invention are：
Make petrochemical industry greasy filth water mixed liquid carry out solid-liquid using acidifying flocculation voluntarily to separate, it is fast with separation of solid and liquid speed, handle medicine
Agent is cheap to be easy to get, and disposal amount is big, and technological process is simple, workable, and the advantages of liquid clarity is good is made after processing, and can
Recycling is carried out to some spent acid and recycles the treatment of wastes with processes of wastes against one another, the processing theory of resources conservation and energy-conserving and environment-protective is realized.
