Description
Technical field
The present invention relates to chemical process field, particularly relate to a kind of reverse osmosis membrane antisludging agent.
Background technology
Membrane separation technique large-scale application is that the Seawater Desalination Project from the sixties in 20th century starts, and hyperfiltration is because of tool
Have that floor space is little, operating cost is low, there is not secondary pollution, stable water outlet, automaticity advantages of higher, process skill at water
Art field the most progressively instead of ion exchange, becomes the major technique of pure water preparation, at present except extensive for sea water, bitter salty
The desalination of water and pure water, ultra-pure water produce and outside reusing sewage, are additionally operable to the necks such as food industry, medical industry, biological engineering
Territory.Reverse osmosis technology is brackish water to impose extraneous motive force to overcome osmotic pressure to make hydrone pass through the reverse osmosis of film
Journey, after reverse-osmosis treated, can remove salinity and the silicon dioxide of in water 99%, and can remove calcium in water, magnesium.
But, reverse osmosis unit is highly prone to the pollution of deposit and fouling, and reverse osmosis membrane fouling drastically influence reverse osmosis
The operational efficiency of device thoroughly, such as: make system operation energy consumption increase, effluent quality degenerates, and even makes membrane component carry time serious
Before scrap, along with deepening constantly of China's industry degree, industrial water consumption is greatly increased, and uses subsoil water to do industry water and have one
Fixed restriction, surface water is a kind of directly by the water source of seasonal effect, has generation microorganism and colloid two aspect highly polluted
, there is inorganic matter in probability and Organic substance obtains scaling fouling simultaneously, and the pretreatment of needs is more complicated, including sterilizing, flocculate, helping
Solidifying, clarification, multi-medium filtering etc..For biological pollution, suitable antibacterial, germicidal lamp or other system can be used to solve,
And for inorganic scale and colloid fouling, then use the method adding efficient scale inhibitor to solve.Antisludging agent is as reverse osmosis water
The class medicament that processing system, prevention dirt deposit on reverse osmosis membrane, market demand is continuously increased.
In recent years, the development of organophosphor acids reverse osmosis membrane antisludging agent is extremely rapid, and they have can be at wider feedwater pH
In the range of use, calcium ion concentration, basicity and the metal ion such as ferrum, manganese are had preferable stability, can efficiently control
CaCO3、CaSO4、BaSO4、SrSO4Deng the formation of dirt, but phosphorus is the nutrient source of antibacterial and algae, containing Phosphorus antisludging agent can be
Antibacterial and microorganism in water-supply-pipe and reverse osmosis membrane system provide the phosphorous nutrient substance needed for growth, thus cause membranous system
There is biological pollution and hidden danger that antibacterial exceeds standard, along with the enhancing of people's environmental consciousness, market is to low-phosphorous, without phosphorus antisludging agent
Demand is increasing, but common antisludging agent is general due to effect, causes that consumption is big, cost is high.
Summary of the invention
For overcoming the deficiency in prior art, it is an object of the present invention to provide a kind of reverse osmosis membrane antisludging agent.

The preparation method of above-mentioned a kind of reverse osmosis membrane antisludging agent, comprises the steps: the deionized water by 2/3, polycyclic oxygen
Succinic acid, kayexalate, poly-aspartate, polylactic acid, BIT, DDA
At room temperature adding in container with order and the corresponding ratio of residue deionized water, stirring is to transparent and homogeneous solution, i.e. reverse osmosis
Permeable membrane antisludging agent.
Beneficial effects of the present invention: the present invention provides a kind of inorganic scale that can efficiently remove deposition on reverse osmosis membrane and glue
The reverse osmosis membrane research of non-phosphorus scale inhibitor of body fouling, the several of formula selection have without phosphorus or low-phosphorous environment-friendly materials compound use, profit
With the synergism between each raw material, substantially increase the using effect of composite drug, reach satisfied comprehensive detergency performance, with
Time due to without phosphorus formula and the addition of a small amount of green bactericide BIT, membranous system biological pollution and antibacterial can be alleviated
The hidden danger exceeded standard, it is to avoid the pollution to environmental water systems.
Epoxysuccinic acid is a kind of nitrogen-free, non-phosphorus organic compound, has chelation, biological fall to many kinds of metal ions
Solution is good, environmental protection, and kayexalate and polylactic acid are respectively provided with scale effect, can disperse can become in difficulty soluble salt crystallization
The difficulty soluble salt microgranule of the heart, reduce or control difficulty soluble salt be gathered into dirt, moreover it is possible to make the crystal generation distortion of lattice of deposition, reach resistance
The purpose of dirt, is used for preventing calcium carbonate, silicate, sulfate and phosphate dirt deposition, and poly-aspartate has as protein
Phthalein amine groups, can biodegradation, there is again the function such as sequestration and dispersion, the introducing of DDA,
Can effectively reduce the generation to earth's surface water-borne glue body dirt (organic/inorganic mixture, oils and fats dirt etc.), and play regulation pH value
Effect, and measure adding of green bactericide BIT and act, by disconnecting antibacterial and the key of algae protein matter, work of killing livestock
, after BIT contacts with microorganism, can the most irreversibly suppress it to grow, thus cause microorganism thin
The death of born of the same parents, therefore common bacteria, fungus, algae etc. are had the strongest suppression and killing action, efficiency of killing livestock is high, degradability
Good, have and do not produce residual, operate safety, compatibility is good, and stability is strong, the features such as use cost is low.
