Embodiment 1
[0035] The process parameters are as follows:
[0036] Take ammonium chloride wastewater with a concentration of 4mol / L from the production line: 200ml; industrial grade quicklime: 30g; blank P507 (organic phase) with a concentration of 1.5mol / L: 3.0L.
[0037] Refer to attached Figure 1~2 , the process steps are as follows:
[0038] a. Ammonia steaming - ammonia absorption
[0039]In a distillation bottle, mix quicklime (CaO) with ammonium chloride wastewater, and heat to distill ammonia. Absorb the evaporated ammonia gas with 3.0L blank P507 with a concentration of 1.5mol / L to form ammonium soap, and the saponification degree of ammonium soap is 25% according to titration measurement; after the reacted solution is filtered or clarified, high-concentration ammonia nitrogen calcium chloride is obtained solution.
[0040] b. Phase inversion
[0041] Add ammonium soap and high-concentration ammonia nitrogen calcium chloride solution into a separatory funnel, mix and stir, ...
Embodiment 2
[0045] The process parameters are as follows:
[0046] Take ammonium chloride wastewater with a concentration of 4mol / L from the production line: 300ml; milk of lime: 40g; blank P507 (organic phase) with a concentration of 0.8mol / L: 10.0L.
[0047] The process steps are as follows:
[0048] a. Ammonia steaming - ammonia absorption
[0049] In a retort, milk of lime (Ca(OH) 2 ) mixed with ammonium chloride wastewater, heated to distill ammonia. Absorb the evaporated ammonia gas with 10.0L blank P507 with a concentration of 0.8mol / L to form ammonium soap, and measure the degree of saponification of the ammonium soap to be 35%; after the reacted solution is filtered or clarified, a high-concentration ammonia nitrogen calcium chloride solution is obtained .
[0050] b. Phase inversion
[0051] Add ammonium soap and high-concentration ammonia nitrogen calcium chloride solution into a separatory funnel, mix and stir, and then separate into layers. The phase inversion operation...
Embodiment 3
[0055] The process parameters are as follows:
[0056] Take ammonium chloride wastewater with a concentration of 4mol / L on the production line: 250ml; industrial grade quicklime: 35g; blank P204 with a concentration of 1.0mol / L: 6.0L, and (LaCe)Cl with a concentration of 1.2mol / L 3 Feed liquid: 20ml.
[0057] The process steps are as follows:
[0058] a. Ammonia steaming - ammonia absorption
[0059] In the distillation bottle, mix quicklime and ammonium chloride wastewater, and heat to distill ammonia. The steamed ammonia gas is absorbed with 6.0L concentration of 1.0mol / L blank P204 to form ammonium soap, and the measured ammonium soap saponification degree is 32%; after the reacted solution is filtered or clarified, a high-concentration ammonia nitrogen calcium chloride solution is obtained;
[0060] b. Phase inversion
[0061] Add ammonium soap and high-concentration ammonia-nitrogen calcium chloride solution into the separating funnel, mix and stir, and then separate...
