Well washing agent for water well and preparation method of well washing agent

The invention discloses a well washing agent for a water well and a preparation method of the well washing agent. The preparation method comprises the following steps: firstly, mixing pediococcus pentosaceus, bacillus aceticus and pseudomonas aeruginosa, and carrying out coating treatment, so as to obtain bioactive particles; then preparing nano microspheres by taking tetraethoxysilane, bioactive particles and 3-[bis(2-hydroxyethyl)amino]propyl-triethoxysilane as raw materials, and performing laser ablation to obtain porous nano microspheres; and finally, preparing a dispersion liquid from sulfamic acid, and then uniformly mixing the porous nano-microspheres with the dispersion liquid and 1,2-dimethyl-3-hydroxyethyl imidazole bis(trifluoromethane sulfonimide salt), thereby obtaining the well washing agent. The well washing agent can be used for water wells, the well washing time is short, and the well washing effect is good. 本发明公开了一种用于水井的洗井剂及其制备方法，先将戊糖片球菌、醋酸杆菌、铜绿假单胞菌混合，包覆处理，得到生物活性粒子；然后以正硅酸乙酯、生物活性粒子和3-[双(2-羟乙基
