Embodiment 1
[0049] The process of treating distilled ammonia wastewater through the system provided by the embodiment of the present invention (wherein, the reagent with oxidizing and precipitation functions is Ca(ClO) 2 , The reagent with reducing and precipitation function is FeSO 4 )include:
[0050] 1. The wastewater after ammonia distillation is cooled to below 35°C by two heat exchangers. The two media of the heat exchanger are circulating water and ammonia wastewater.
[0051] 2. Filter the waste water treated in process 1 through a paper bag filter, and the filter aperture of the paper bag is selected to be 0.1-0.5mm.
[0052] 3. Put 0.1mm diameter Ca(ClO) into the wastewater treated by process 2 in the mixing and mixing tank according to the solid-liquid ratio of 1:200-1:300 2 , The stirring speed of the stirrer is 20-80r / min, and the stirring time is 20-30min.
[0053] 4. In the same mixing tank, the FeSO put in the wastewater after treatment in process 3 according to the liquid-to-liqui...
