The content of each material in the permeate obtained by the secondary nanofiltration treatment is shown in table 7:
TABLE 7 detection results of secondary nanofiltration permeate without neutralization treatment step
From the data of the comparative example and the example 1, the neutralization treatment has small difference of the retention rate of the total nitrogen and the ammonia nitrogen, but greatly improves the retention rate of the total phosphorus, and the working pressure of the comparative example 1 when the secondary nanofiltration is carried out is larger than the working pressure of the example 1.
And (3) carrying out evaporation concentration crystallization on the obtained secondary nanofiltration permeating liquid, and collecting condensed water in the evaporation concentration process, wherein the evaporated crystal salt sodium chloride does not meet the industrial salt standard, and the content of phosphorus-containing compounds in the sodium chloride is higher.
