Abstract
A new wastewater treatment method has been developed for the production of urea to the stage of desorption and hydrolysis, aimed at creating recovery technologies. The considered method carries a positive economic (by reducing the cost price of urea and saving energy resources) and environmental impact (by reducing the burden on biological treatment plants). The method of electrochemical degradation followed by anionization and cationization was used to purify condensates of juice carbamide production pair. The results of the study of a new method for cleaning condensates of a juice pair: the degree of processing of sodium hypochlorite is 99.5÷100 %; the degree of wastewater treatment from compounds that contain bound nitrogen is 96÷98 %. Practical value: the proposed technical solution allows to minimize energy consumption for urea production; purified water can be used as feed water for boilers, circulating water for heat exchangers, and also for the production of nitric acid.
