AI Technical Summary
Existing flocculants have long reaction times, cannot be stored for long periods, are not suitable for efficient emergency treatment of large amounts of oily wastewater in emergency scenarios, and do not meet on-site preparation requirements.
A flocculant is prepared by mixing and granulating components such as etherified starch, sodium bentonite, tannin-modified chitosan, and nano-magnetic iron oxide. Carbonate and citric acid are added as co-reactants to form components A, B, C, and D, which are suitable for oily wastewater systems where anions and cations coexist.
The flocculant flocculates rapidly in water with a short flocculation time, is suitable for a wide pH range, has good salt resistance, meets the emergency needs at accident sites, and has a simple preparation process and mild conditions.
