Abstract Cyanuric acid is a main raw material for sodium dichloro-isocyanuric and trichloro-isocyanuric acid production which are high-efficient healthy reagents for eliminating algae germcide.The traditional production technology of cyanuric acid is urea thermolysis and refinement of sulphuric acid acidification.Accompanied with the production,a large amount of waste gas containing ammonia and acidic waste water are discharged.In order to solve this pollution problem,many factories adopt a method of neutralizing acidic waste water with ammonia byproduct and lime.However,the method brings pollution to environment and the economic efficiency is low.In this paper,the process of production was analyzed and optimized from the beginning of clean production and the target of changing waste into treasure and protecting the environment is reached.
