Embodiment approach
[0042] As an embodiment of the present invention, the photocatalyst material is a chelated photocatalyst material doped with nano-noble metal elements after chemical coordination bond chelation functional element doping technology transformation; the nano-noble metal elements are platinum, One or more of rhodium and palladium; the raw materials use nano-noble metals to chelate and hybridize photocatalyst materials, which greatly improves the separation efficiency of photogenerated carriers and inhibits the recombination of electrons and holes, thereby further broadening the The light wave absorption range of the photocatalyst effectively turns the performance of the photocatalyst itself from absorbing only ultraviolet rays to absorbing most of the visible light and some far-infrared light, thereby effectively reducing the use restrictions of photocatalyst materials and effectively enhancing the performance of the reverse osmosis composite membrane.

The invention belongs to the technical field of water treatment, and specifically relates to a method for preparing a multilayer reverse osmosis composite membrane, which includes a casing, a water inlet pipe and a water outlet pipe; the casing is designed in an "I" shape; There is a pressurized chamber; one end of the housing is provided with a first groove; the end of the housing away from the first groove is provided with a second groove; both the first groove and the second groove are "T" shape design; the side walls of the first groove and the second groove are threaded; the water inlet pipe is connected to the housing through the first groove; Put pressure on the water flow, speed up the penetration efficiency of the water flow, and at the same time rotate the rotation shaft, so that the ultraviolet rays scattered by the ultraviolet lamp can be evenly diffused outwards, effectively improving the purification effect of the photocatalyst material in the permeation bag on the permeation bag itself, and at the same time by setting a protective layer , to prevent the separation layer from being directly impacted by the water flow, effectively enhancing the durability of the purification performance.
Description
technical field [0001] The invention belongs to the technical field of water treatment, in particular to a preparation method of a multilayer reverse osmosis composite membrane. Background technique [0002] Reverse osmosis membrane is an artificial semipermeable membrane with certain characteristics made by simulating biological semipermeable membrane. It is the core component of reverse osmosis technology. These substances and water are separated through a semi-permeable membrane. Membrane fouling in the prior art has seriously restricted the large-scale application and promotion of reverse osmosis technology, especially in the fields of highly polluted water treatment, water reuse, and chemical separation. application, membrane fouling will directly lead to a significant decrease in the permeation flux of the membrane, a decrease in the production efficiency of the system, and an increase in operating costs and energy consumption; membrane fouling will also lead to freque...
