A urea ammonium nitrate solution and an integrated clean production method are a liquid nitrogen fertilizer production technology, and the method comprises the following steps: premixing a urea melt solution and a part of an ammonium nitrate solution, and introducing the premixed solution into a neutralization reaction system of ammonium nitrate to realize molecular integration of urea and ammonium nitrate in a synthesis stage; performing evaporation concentration, on-line proportion fine adjustment, compound stabilizer treatment, cooling and filtering and the like to obtain a high-stability finished product. According to the invention, solidification and redissolution processes of urea and ammonium nitrate in the traditional process are omitted, so that the energy consumption is obviously reduced; through process innovation and use of the compound stabilizer, the chemical stability (inhibiting ammonia volatilization and nitrite generation) and the physical stability (preventing crystallization) of the product are fundamentally improved, and the product performance is excellent. The whole technological process is short, airtight, clean and low in investment and production cost.
