Embodiment 1

[0028] like figure 1 As shown, a treatment process for removing dissolved organic matter in reverse osmosis concentrated water includes an inlet pump 1, a packing reaction tower 2 and a drainage pump 5, and the output end of the inlet pump 1 is connected to the input end of the packing reaction tower 2 through a pipeline , the output end of the packing reaction tower 2 and the input end of the drainage pump 5 are connected by a pipeline, and the inside of the seasoning reaction tower 2 is filled with modified chitosan filler 3 and modified concave-convex filler 4 successively from bottom to top, The modified chitosan filler 3 accounts for 45% of the total volume of the filler reaction tower 2, and the modified attapulgite filler 4 accounts for 55% of the total volume of the filler reaction tower 2;

[0029] The process of the process is as follows: PH is 8.1, DOC is 60mg / L, and TDS (total dissolved solids) is 34110mg / L. Chitosan filler 3 and modified concave-convex soil fille...

Embodiment 2

[0044] like figure 1 As shown, a treatment process for removing dissolved organic matter in reverse osmosis concentrated water includes an inlet pump 1, a packed reaction tower 2 and a drainage pump 5, and the output of the inlet pump 1 is connected to the input of the packed reaction tower 2 through a pipeline , the output end of the packing reaction tower 2 and the input end of the drainage pump 5 are connected by a pipeline, and the inside of the seasoning reaction tower 2 is filled with modified chitosan filler 3 and modified concave-convex filler 4 successively from bottom to top, The modified chitosan filler 3 accounts for 35% of the total volume of the packed reaction tower 2, and the modified attapulgite filler 4 accounts for 65% of the total volume of the packed reaction tower 2;

[0045] The process of the process is as follows: PH is 6.9, DOC is 31mg / L, and TDS (total dissolved solids) is 27892mg / L. The cold-rolled reverse osmosis concentrated water enters the packi...

Abstract

The invention relates to the technical field of water treatment, and discloses a treatment process for removing dissolved organic matters in reverse osmosis concentrated water, the treatment process comprises a water inlet pump, a filler reaction tower and a drainage pump, the output end of the water inlet pump is connected with the input end of the filler reaction tower through a pipeline; the output end of the filler reaction tower is connected with the input end of the drainage pump through a pipeline, and the interior of the filler reaction tower is sequentially filled with modified chitosan filler and modified attapulgite filler from bottom to top; the process comprises the following steps: cold-rolled reverse osmosis concentrated water enters a filler reaction tower through a water inlet pump; then sequentially passing through the modified chitosan filler and the modified attapulgite filler upwards; and finally, discharging the reverse osmosis concentrated water reaching the standard through a drainage pump. The treatment process for removing the dissolved organic matters in the reverse osmosis concentrated water disclosed by the invention can effectively solve the problem that the reverse osmosis concentrated water pollutes the environment, belongs to a green and environment-friendly production process, and has good social benefits and environmental benefits.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a treatment process for removing dissolved organic matter in reverse osmosis concentrated water. Background technique [0002] Dissolved organic carbon, referred to as DOC, generally refers to organic carbon that can pass through a filter membrane with a pore size of 0.45 microns and is not evaporated and lost during the analysis process. It includes a portion of the carbon in colloidal organic matter that is not retained by the filter. The composition of DOC is extremely complex, and the main components are (1) carbohydrates (monosaccharides and polysaccharides); (2) amino acids; (3) hydrocarbons and halogenated hydrocarbons; (4) vitamins, mainly derived from bacteria, etc.; (5) humus. However, the dissolved organic carbon in reverse osmosis concentrated water is very high, and direct discharge without treatment will endanger the environment. Contents of the inventio...
