This invention relates to the field of water treatment chemicals, and discloses a hydroxyl-based coagulant aid, its preparation method, and its application. The coagulant aid is composed of solid polyaluminum chloride, polyvinyl alcohol, urea, an aqueous solution of alkyl glycosides, sodium gluconate, sodium tetraborate decahydrate, triethanolamine, deionized water, and glacial acetic acid for pH adjustment. This invention reduces the system viscosity through urea, and, combined with the spatial isolation of alkyl glycosides and the coordination chelation of sodium gluconate, inhibits the salting-out and phase separation of polyvinyl alcohol induced by high concentrations of polyaluminum chloride. The system utilizes sodium tetraborate decahydrate to construct a pH-regulated delayed cross-linking mechanism, maintaining liquid-phase homogeneity under slightly acidic conditions. When introduced into neutral or weakly alkaline water, the agent can undergo in-situ cross-linking with the water to form a network structure, which, in conjunction with inorganic aluminum salts, achieves the netting and sedimentation of suspended particles. This invention balances long-term storage stability in high-salt systems with highly efficient turbidity removal performance.
