Desalting equipment and method for realizing fertilizer utilization of cow breeding wastewater

The invention discloses desalting equipment and method for realizing fertilizer utilization of cow breeding wastewater and belongs to the technical field of water pollution control. The desalting equipment mainly comprises a raw liquid tank, a temporary storage tank, a reverse osmosis filter, an electric desalting device and a washing device; due to the arrangement of a drain hole in the temporarystorage tank, the water outflow is convenient to regulate according to a liquid level in the temporary storage tank, and the phenomenon that the wastewater is not treated in time during relatively high liquid level to affect the desalting efficiency of the wastewater is avoided; due to the arrangement of the reverse osmosis filter, on the one hand, the volume of a reverse osmosis filtering membrane drawer is reduced, and mounting and dismounting are convenient to realize; on the other hand, due to the adoption of a splicing way, the stability of the reverse osmosis filtering membrane drawer is improved, and the pheno
