AbstractNOVELTY - Preparation of composite resin adsorbent comprises taking modified mussel shell powder and petroleum hydrocarbon-degrading bacteria, saturating modified mussel shell powder, adding sodium alginate solution, mixing, injecting calcium chloride solution, and crosslinking; taking methacrylic acid ester monomer, styrene, initiator, and emulsifier, adding water, stirring, adding crosslinking agent and pore-forming agent, and polymerizing; and taking mussel shell powder-immobilized microbial particles and coupling agent, adding acrylic acid ester copolymer emulsion, stirring, and vacuum drying. USE - Method for preparing composite resin adsorbent (claimed) used for microbial degradation of oil. ADVANTAGE - The composite resin adsorbent has fast oil absorption speed. DETAILED DESCRIPTION - Preparation of composite resin adsorbent comprises:(A) taking 10 pts. wt. modified mussel shell powder and 20-50 pts. wt. petroleum hydrocarbon-degrading bacteria, preferably 6x 109 cell/g broth mixed seed, saturating modified mussel shell powder, adding 1000 pts. wt. 4-8 wt.% sodium alginate solution, mixing, injecting to 2.5-3.5 wt.% calcium chloride solution, and crosslinking for 4-12 hours;(B) taking 65-85 pts. wt. methacrylic acid ester monomer, 20-30 pts. wt. styrene, 0.5-1.5 pts. wt. initiator, and 3-7 pts. wt. emulsifier, adding 250-450 pts. wt. water, stirring for 1-2 hours to obtain emulsion, adding 3-5 pts. wt. crosslinking agent and 45-55 pts. wt. pore-forming agent, and polymerizing at 65-85 degrees C for 4-8 hours under nitrogen gas to obtain acrylic acid ester copolymer emulsion; and(C) taking 5-20 pts. wt. mussel shell powder-immobilized microbial particles and 0.1-0.5 pt. wt. coupling agent, adding acrylic acid ester copolymer emulsion, low speed stirring at room temperature, and vacuum drying.
