Problems solved by technology
According to market research, the current inorganic ceramic membranes, especially inorganic ceramic membrane plates, have the following problems in actual use: First, because the thickness of ceramic membrane plates is generally 8-15 mm and the area is 1-3 square meters, the strength of ceramic membrane plates Not high, high brittleness, after working under harsh conditions for a period of time, the ceramic membrane plate is prone to cracking, which reduces the filtration efficiency; second, the adsorption of the film on the surface of the ceramic plate carrier is not high, and the film layer will partially fall off and separate, affecting Filtration effect; the third is that the membrane flux of the membrane layer is not high enough, and the size of the membrane pores is not very uniformly dispersed, which is easy to cause blockage of the membrane pores, increases the difficulty of backwashing, and increases the filtration cost

Abstract
The invention discloses a manufacturing method of a high-efficiency inorganic film filtering plate for water treatment. The manufacturing method comprises the following steps: firstly stirring emery,Suzhou soil, alpha-Al2O3, titanium aluminum carbide, feldspar, methyl cellulose, dextrin, lepidolite, bentonite, talcum powder and oleic acid according to the matching ratio, carrying out decaying andmechanical pressing for molding, drying and sizing, spraying a layer of zeolite slurry film on the platy surface, primarily sintering, coating film slurry consisting of the emery, the Suzhou soil, the feldspar, titanium oxide sol, fiber, the talcum powder, the bentonite, the dextrin, the lepidolite and sodium humate, secondarily sintering after natural drying, cooling, discharging from a furnace,assembling, inspecting, packaging and warehousing. The high-efficiency inorganic film filtering plate is widely used for treatment of industrial waste water in chemistry, foods, medicines, chemical fertilizer, metallurgy, paper making and printing and dyeing and the like, and has the advantages of high filtering efficiency, strong pollutant intercepting capability, good effluent quality, long service life and low operation cost.
Description
technical field [0001] The invention relates to solid-liquid separation of wastewater in the field of environmental protection, and aims to provide a high-efficiency, wide-adaptability, and low-cost manufacturing method of a high-efficiency inorganic membrane filter plate. Background technique [0002] In the process of removing SS and oil in wastewater, activated carbon adsorption, modified bentonite adsorption, and macroporous resin adsorption are the most representative traditional technologies. The principle is to use solid adsorbents with large specific surface area, high porosity, and polarity Strong, particles with charged polarity have good physical adsorption and surface chemical activity, have good adsorption capacity for various pollutants in wastewater, and achieve the purpose of purifying water. However, the traditional filtration technology has disadvantages such as high price, single function, high investment cost, and poor backwashing effect. [0003] Inorga...
