The invention relates to a one-dose one-bath low-temperature type pre-treatment compound preparation which comprises the following components in mass percentage: 35.3-52.1% of hydrogen peroxide additive, 11.1-23.1% of peroxysulphate, 2.7-8.0% of sodium hydroxide, 5.5-15.4% of multifunctional additives, 11.8-28.6% of metasilicic acid alkali metal and 2.7-8.0% of surface active agent. According to the compound preparation, multiple functions, such as a refining function, a bleaching function, a permeating function and the like, are integrated into a whole; one-dose effect of a pre-treatment agent is realized; inconvenient operation caused by a plurality of dosage forms and troubles, such as time consumption, labour consumption, material consumption and the like, in the production process are avoided; the use amount of auxiliary additives, such as sodium hydroxide and the like, is reduced; annealing, boiling and bleaching processes in pre-treatment are combined into the one-bath method; the process flow is simplified; simultaneously, the pre-treatment temperature is reduced; the comprehensive production cost is also reduced; and the one-dose one-bath low-temperature type pre-treatment compound preparation disclosed by the invention has good application prospect.
