Preparation method of low-chemical-component-residue preparation for removing pesticide

The invention discloses a preparation method of a preparation for removing pesticide low-chemical-component residues, which comprises the following steps: taking a nonionic surfactant, an anionic surfactant, coconut oil and a Luhua extract essence, and mixing the nonionic surfactant, the anionic surfactant, the coconut oil and the Luhua extract essence through a mixer to obtain a surfactant; taking konjac glucomannan, sodium alginate, guar gum, xanthan gum and pure water, feeding the konjac glucomannan, the sodium alginate, the guar gum, the xanthan gum and the pure water into a mixing machine, and mixing to obtain a thickening agent; the preparation method comprises the following steps: mixing D401 macroporous styrene chelating ion exchange resin and a thickening agent through a mixing machine to obtain a viscous compound material; taking pure water, polystyrene-based fiber, capsid protein and sodium bicarbonate, and feeding the pure water, the polystyrene-based fiber, the capsid protein and the sodium bicar
