Preparation method of targeted catalyst for treating wastewater containing aromatic compounds

Provided is a preparation method of a targeted catalyst for treating wastewater containing aromatic compounds. The method comprises the following steps that a solution containing 5%-15% of active component salt is dissolved in deionized water of 40 DEG C to 80 DEG C; an ammonium salt is added to enable the pH to be increased to be 6.5 to 7.5, the temperature is kept, and stirring is conducted for 40 min to 80 min at the speed of 60 r / min to 100 r / min; filtering is conducted, precipitates are washed 3-5 times with deionized water and dried for 3 h to 6 h in a muffle furnace of 100 DEG C to 110 DEG C, and granular powder is obtained; 10%-30% by mass of granular powder, 1%-5% by mass of lubricating agent, 4%-15% by mass of gelatinizing agent, 50%-80% by mass of alumina powder and 1%-3% by mass of pore-expanding agent are mixed and stirred to be uniform and then rolled to be 2 mm to 8 mm; an obtained product is dried for 3 h to 5 h in a drying oven of 100 DEG C to 200 DEG C; the dried product is roasted for 2 h to 6 h in the muffle furnace of 400 DEG C to 800 DEG C. The targeted catalyst is obtained through a mixed mode of precipitating and melting, larger channels can be formed in the catalyst, a larger specific surface area can be obtained, and therefore organic matter in the wastewater fully makes contact with active metal oxide in the catalyst, and the degradation effect on the organic matter is improved.
