Embodiment 1
[0023] A mixed ion exchange resin that can adjust the pH of the effluent, which is composed of a certain proportion of acid resin and alkaline resin. The mixed ion exchange resin can control the PH value of the effluent water within the required range while performing ion exchange on the treated raw water.
[0024] The acid resin is a strong acid cationic resin or a weak acid cationic resin or a mixture of a strong acid cationic resin and a weak acid cationic resin. The basic resin is a strongly basic anion resin or a weakly basic anion resin or a mixture of a strongly basic anion resin and a weakly basic anion resin.
[0025] It should be noted that any acid resin or basic resin can be used as the mixed ion exchange resin capable of adjusting the pH of the effluent. The type of acid resin can be but not limited to 732, 734 or D113. The model of the alkaline resin can be but not limited to 717, D301 or D311.
[0026] It should be noted that in actual use, according to different ra...
Embodiment 2
[0029] A mixed ion exchange resin that can adjust the pH of the effluent, which is composed of a certain proportion of acid resin and alkaline resin. Among them, in terms of volume ratio, the filling ratio of acid resin and alkaline resin is 1:0.8 to 1:6, and the pH value of the effluent is 7.5±1. The ratio of acidic resin and alkaline resin can make the PH value of the effluent be controlled at 7.5±1.
Embodiment 3
[0031] A mixed ion exchange resin that can adjust the pH of the effluent. The filling ratio of acid resin and alkaline resin is 1:1 to 1:5 in volume ratio, and the pH of the effluent is 7.5±1. The mixed ion exchange resin can not only meet the regulation of water quality, but also control the PH value of the effluent water.
