Description
Technical Field
The invention relates to a seawater desalination membrane treatment process.
Background
Sea water desalination, i.e. the desalination of sea water to produce fresh water, is an open source incremental technology for realizing the utilization of water resources. The currently used methods for desalinating seawater include a seawater freezing method, an electrodialysis method, a distillation method, a reverse osmosis method, and an ammonium carbonate ion exchange method, and the currently applied reverse osmosis membrane method and the distillation method are the mainstream in the market. The distillation method has high energy consumption and gradually loses economic benefits. Reverse osmosis, also commonly referred to as ultrafiltration, separates seawater from fresh water by a semi-permeable membrane that allows only solvent to permeate but not solutes to permeate. In general, fresh water diffuses through the semipermeable membrane to the seawater side, so that the liquid level on the seawater side gradually rises until a certain height, and the process is permeation. The reverse osmosis method has the advantages of low energy consumption, high effluent quality, less equipment investment, short construction period, small occupied area, low operation cost and the like, and along with the continuous progress of reverse osmosis membrane technology, the reverse osmosis membrane technology is more and more emphasized by people, and the market share is rapidly improved. The seawater desalination membrane (reverse osmosis membrane) is a key factor determining the seawater desalination effect.
The existing seawater desalination membrane basically takes a polyamide structure as a main part, firstly a porous polysulfone supporting layer is prepared on a non-woven fabric substrate, and then a cross-linked aromatic polyamide functional layer is obtained on the porous polysulfone supporting layer through the interfacial polymerization reaction of m-phenylenediamine and trimesoyl chloride. For example, the preparation method of a high-performance seawater desalination membrane disclosed in patents CN 104474928 and CN202010106041.4, the prepared seawater desalination membrane and the protection device for a seawater desalination membrane disclosed in CN201921037421.6 have simple pre-filter equipment, but with serious seawater pollution, enteromorpha spreads in main sea areas, which seriously affects seawater filtration, so how to reduce the burden of the filter equipment and turn the enteromorpha into fertilizer becomes a technical problem which is urgently needed to be solved.

S2.2, with the aid of the secondary fishing device (13), firstly, rotating the secondary fishing rotating gear disc (40) to enable the secondary fishing auger (45) to face downwards; then, the secondary fishing rotary driving part (42) drives the steering gear to rotate through a central transmission shaft, and the steering gear drives the secondary fishing auger (45) to rotate through the transmission shaft so as to output sundries; then, when the secondary fishing auger (45) is wound by sundries, the secondary fishing rotary gear disc (40) drives the secondary fishing auger (45) to swing upwards so as to clean the attached sundries;
s2.3, by means of the output filtering device (14), firstly, seawater enters the V-shaped cavity through the self-filtering middle mesh screen (46) and the self-filtering side mesh screen (47); then, when the blockage occurs, the self-filtering dredging push rod (48) drives the outer top of the hinge rod (49) through the self-filtering to lead the self-filtering side swinging rod (52) to swing outwards, and the self-filtering side thimble (53) enters the strip-shaped meshes of the self-filtering side mesh screen (47) to dredge; then, the self-filtering side swing tail part (54) pulls one end of the self-filtering top swing L rod (55), and the self-filtering top outer pull arm (56) enters strip-shaped meshes in the self-filtering middle mesh screen (46) to be dredged.
