The invention relates to a treatment method for wastewater generated in the production process of molecular sieve based catalysts. The method comprises the following steps that an alkali suspension isadded to remove suspended solids, phosphate radicals, salinity and the like in water; volatile organic compounds in the water are removed by utilizing gas purging; most of COD, ammonia nitrogen and the like in the water are removed by utilizing a wet-process catalytic oxidation technology, so as to be converted into carbon dioxide, water, nitrogen and the like; and finally, the COD, total phosphorus, total nitrogen and the like in the water are further removed by utilizing conventional biochemical treatment, so that the water can be discharged up to the standard. Compared with the prior art,the treatment method has the advantages that the wet-process catalytic oxidation technology is utilized, so that most of organic matters can be removed, and the treatment effect can be stable; the biodegradability of the treated wastewater can be improved, and the wastewater can be treated in a conventional biochemical mode; and the structure of equipment is simple, scaling is not liable to occur,and stable long-term operation can be realized.
