Description
Technical field
The invention belongs to tertiary oil recovery sewage treatments, are related specifically to neopelex in removal aqueous solution containing HPAM
Technique.
Background technique
Tertiary oil recovery technology is current one of the key technology for improving oil recovery.Tertiary oil recovery technology mainly includes gathering
Object drive, surfactant flooding and combination flooding etc. are closed, as extraction liquid measure increases year by year, the sewage quantity generated after processing is also more next
It is bigger.Tertiary oil recovery sewage composition is complex, but since Polymer LB film and surfactant sodium dodecyl base benzene sulfonic acid sodium salt exist
Extensively using general, caused often to contain HPAM and neopelex in tertiary oil recovery sewage during tertiary oil recovery.Though
Right tertiary oil recovery sewage is mostly used in re-injection, but the outer discharge capacity of tertiary oil recovery sewage is in increase trend year by year in recent years, by
It is difficult to degrade in neopelex, and can significantly reduce water body dissolved oxygen amount, water body self-purification ability is caused to decline, serious shadow
Anionic surfactant in the water such as neopelex is all included in monitoring project, China's drink by Xiangshui County's matter, countries in the world
One of main monitoring project is also classified as with water water sanitary standard (GB 5749-2006).Therefore, it explores removal and contains HPAM
The technique of neopelex in aqueous solution, be solve environmental problem brought by current tertiary oil recovery wastewater disposition must
Standby technology.
The removal technique of neopelex mainly has absorption method, catalytic degradation method and microbial degradation in aqueous solution
Method etc..There are respective defects for these methods, as the treating capacity of absorption method is smaller, the condition of catalytic degradation method is harsh, micro-
Biological degradation method period length etc..Using beta-cyclodextrin can quick neopelex in inclusion aqueous solution containing HPAM, 12
Sodium alkyl benzene sulfonate is formed inclusion complex, the dissolubility of inclusion complex in aqueous solution with beta-cyclodextrin after inclusion
Lower than beta-cyclodextrin, it may make the inclusion complex in aqueous solution containing HPAM crystallizes to be precipitated by cooling down, reach removal containing HPAM
The purpose of neopelex in aqueous solution.Beta-cyclodextrin is nontoxic, cheap, and separating technology is simple, quick, is
A kind for the treatment of process of green.
Summary of the invention
