摘要（英）：

The invention relates to a preparation method of a scale inhibition dispersant for sewage treatment. The raw materials include: UP water, water glass, an oxidant, ammonium tungstate, thiourea, ammonium ceric nitrate, coal gangue powder, sepiolite, rectorite, attapulgite clay, sodium benzoate, ethylenediamine, ethylenediamine, binary acid and chlorine dioxide. The scale inhibition dispersant can reach a fluorine removal rate of 98-99.2% on fluorine-containing industrial wastewater, and a decolorization rate of 93-97%, has a chromium ion removal rate up to 99.5-99.9%, a calcium carbonate scale inhibition rate of 98-99%, a phosphorus elution rate up to 99.4-99.8%, and a wax inhibition rate of 82-87%, can effectively resist the erosion of 1300-1700mg/L chlorine ions to metals, and can reach acalcium carbonate scale inhibition rate up to 99-99.6%, a strontium sulfate scale inhibition rate up to 99.2-99.6%, a magnesium hydroxide and calcium sulfate scale inhibition rate up to 99.4-99.8%, and a carbon steel corrosion inhibition rate of 89-97%.
