The invention discloses a comprehensive utilization method for
sludge generated in an ASP flooding
sewage treatment process, comprising the following steps of: adding inorganic acid in the
sludge generated in the ASP flooding
sewage treatment process, stirring and filtering, wherein the filtrate from which little
crude oil is recycled can continue to serve as coagulant; and then,
drying sludge residue, crushing the dried residue to have needed
granularity, and then using the crushed material as
raw material for preparing swellable particle profile control agent.
Mass ratio of main reactants for preparing the swellable particle profile control agent is as follows: acrylic
amide:
acrylic acid: the sludge:
bentonite: 2% methylenebiacrylamide: 3%
persulfate = 10-25: 2-4: 5-12: 5-12: 0.3-1.0: 0.3-1.0; by the comprehensive utilization of the sludge generated in the ASP flooding
sewage treatment process, the harmless and resource-oriented treatment on the sludge generated by the ASP flooding is implemented, the obtained coagulant can be used for the ASP flooding
sewage treatment, and the prepared swellable particle profile control agent has the characteristics of excellent temperature tolerance,
salinity tolerance, suspension property and expansibility, and the like.
