Embodiment Construction
[0037] refer to figure 1 , figure 2 and image 3 .
[0038] The invention provides a high-concentration printing waste liquid synchronous decolorization and nitrogen recovery treatment equipment, which includes a processor 1, a #1 filter 7, a nitrogen recovery tank 8 and a #2 filter 10.
[0039] The processor 1 described therein comprises a reaction tank 2 , a primary separation tank 3 , a secondary separation tank 4 , a water storage tank 5 , and a return water pump 11 .
[0040] The reaction tank 2 is divided into two compartments, the bottom of which is connected to each other. A mixer 17 is arranged in the first compartment reaction tank, and the stirred waste liquid reacts with the resin to form a paste. The upper part of the second compartment of the reaction tank is provided with a catheter 21 and a first-stage The separation tank 3 is connected, and the diameter of the catheter is greater than 20cm;
[0041] The first-stage separation tank is provided with a mixer...
