Embodiment 1
[0037] 1. Centrifuge seawater decalcification test
[0038] A centrifuge equilibrium adsorption seawater decalcification processing method, the steps are as follows:
[0039] (1) Mix 12 kg of adsorption material with 30 kg of water to make a slurry;
[0040] (2) Let the slurry in step (1) stand for 5 minutes, settle the material, and then pour the upper layer of clear water to obtain the lower layer material-water mixture;
[0041] (3) The mixture is controlled by the pump to feed at a speed of 0.8 m 3 / h enters the centrifuge, centrifuges through the filter cake and flows out from the water outlet, and the obtained filtrate is decalcified seawater.
Embodiment 2
[0043] 1. Centrifuge seawater decalcification test
[0044] A centrifuge equilibrium adsorption seawater decalcification processing method, the steps are as follows:
[0045] (1) Mix 12 kg of adsorption material with 24 kg of water to make a slurry;
[0046] (2) Set aside the slurry in step (1) for 4 minutes to settle the material, then pour the upper layer of clear water to obtain the lower layer material-water mixture;
[0047] (3) The mixture is controlled by a pump to feed at a speed of 0.6 m 3 / h enters the centrifuge, centrifuges through the filter cake and flows out from the water outlet, and the obtained filtrate is decalcified seawater.
Embodiment 3
[0049] 1. Centrifuge seawater decalcification test
[0050] A centrifuge equilibrium adsorption seawater decalcification processing method, the steps are as follows:
[0051] (1) Mix 12 kg of adsorption material with 36 kg of water to make a slurry;
[0052] (2) Set aside the slurry in step (1) for 6 minutes to settle the material, then pour the upper layer of clear water to obtain the lower layer material-water mixture;
[0053] (3) The mixture is controlled by a pump to feed at a speed of 1 m 3 / h enters the centrifuge, centrifuges through the filter cake and flows out from the water outlet, and the obtained filtrate is decalcified seawater.
[0054] Result detection and data analysis:
[0055]After inspecting the seawater in a container with a depth (height) of 1.2 meters, the material was stirred for 5 minutes, and it was found that the material has basically sunk to the bottom, and most (> 85% or even more than 90%) of the seawater can be removed by pouring. Pour off ...
