The invention discloses a purifying treatment agent for coal-washing wastewater and a preparation method thereof. The purifying treatment agent is prepared from the following materials in parts by weight: 30-40 parts of sepiolite, 15-20 parts of montmorillonite, 10-15 parts of medical stone, 15-20 parts of polyacrylamide, 5-10 parts of sodium polyacrylate, 3-6 parts of aluminium polychlorid, 2-4 parts of sodium lignin sulfonate, 3-5 parts of alum powder, 6-9 parts of ferrous sulfate, 8-12 parts of guar gum powder, 5-10 parts of nano carbon, 4-8 parts of porous calcium phosphate, 10-15 parts of carboxymethyl chitosan, 5-10 parts of sodium alginate, 2-3 parts of span-80, 1-2 parts of sodium lauryl sulfate, 1-2 parts of stearic acid and 0.5-1 parts of gamma-aminopropyltriethoxysilane. The purifying treatment agent disclosed by the invention has the advantages that the flocculation effect is good, impurity particles in coal-washing water can be rapidly agglutinate and settled, simultaneously heavy-metal elements in the coal-washing water can be absorbed, the purifying effect is very obvious, the water purifying effect is 4-6 times of that of the common flocculating agent; and the used amount is less, the efficiency is high, the cost is low, the benefit is high, the complete environmental-friendly effect is achieved and the application prospect is wide.
