The invention provides a decolorizing adsorbent for sewage treatment and a preparation method thereof. The preparation method of the decolorizing adsorbent for sewage treatment is characterized by comprising the following steps: (1) weighing 35-55 parts by weight of magnesium sulfate, 3-6 parts by weight of concentrated sulfuric acid and 1-3 parts by weight of an initiator, carrying out stirring and mixing, adding 30 parts by weight of water, and carrying out a reaction at 220-250 DEG C for 1 h; and (2) adding 12-22 parts of bentonite and 25-35 parts of 200-300-mesh porous perlite micropowderinto a product obtained after the reaction in the step (1), carrying out stirring and mixing, and then conducting granulation, wherein granulation granularity is 0.3-0.5 micrometer. The decolorizing adsorbent can effectively remove pigments in sewage, and is low in cost, free of toxicity and secondary pollution and good in flocculation effect. 本发明提供一种污水处理用脱色吸附剂及其制备方法。本发明的污水处理用脱色吸附剂的制备方法，其特征是：该方法包括如下步骤：（1）按重量份数取硫酸镁35-55份、浓
