A glazing technology for purple-sand tea sets relates to the technical field of purple sand and comprises the following technological steps: 1) preparing a green body, specifically taking purple sand at Huainan area of Anhui province of China as a main material to prepare the green body; 2) taking out the green body, baking to dry at a room-temperature environment, so as to prevent deformation of the green body; 3) sintering the green body, specifically for first sintering in a kiln, employing reduction flame for sintering, heating to 950-1050 DEG C, and sintering for 16-18 h, so as to mainly eliminate humidity and remove alkali in the green body; 4) keeping warm for 10-20 min, naturally cooling and discharging from the kiln; 5) uniformly glazing the surface of the green body; and 6) sintering the glazed green body, specifically for secondary sintering in a kiln, employing reduction flame for sintering, sintering at 130 DEG C for 20 h, keeping warm for 10-20 min, and naturally cooling and discharging out of the kiln. The technology is simple, and by adding compositions such as shells, bluestone and the like, the sintered tea set has spots on the surface and has beautiful color.

The embodiment of the invention provides a method and device for determining the content of glauconite in glauconite sandstone. The method comprises steps of: making a superposed curve of a volume density logging curve and a neutron porosity logging curve of a reference logging, and identifying the glauconite sandstone; subjecting a glauconite content amplitude value acquired from core data, the corresponding volume density logging curve, and the corresponding neutron porosity logging curve to multivariate linear regression in order to obtain a linear relation among a glauconite content identification factor, the volume density data, and the neutron porosity data; computing a glauconite content identification factor of the reference logging according to the linear relations; subjecting the glauconite content amplitude value and the glauconite content identification factor to nonlinear regression to obtain a nonlinear relation between the glauconite content and the glauconite content identification factor; and determining the content of glauconite in glauconite sandstone of a logging to be identified according to the nonlinear relation. The method and the device may accurately determine the content of glauconite in glauconite sandstone.

The invention discloses an adsorbent for treating lead-containing wastewater and a preparation method thereof. The adsorbent is mainly composed of, by weight, 1-8 parts of brown alga powder, 3-10 parts of glauconite powder, 3-5 parts of magnesite powder, 3-15 parts of bauxite, 0.6-4 parts of (3-mercaptopropyl) triethyoxy silane, 1-10 parts of chitosan, 1-4 parts of modified polycarboxylate, 2-10 parts of barite powder, 10-50 parts of polymer binder, 60-100 parts of quartz wool, 5-20 parts of buckwheat powder and 0.3-5 parts of titanium isopropanol. When adsorbent granules prepared from brown alga powder, glauconite powder, magnesite powder, bauxite, (3-mercaptopropyl) triethyoxy silane, chitosan,,polymer binder, buckwheat powder and titanium isopropanol are put into lead-containing water, the adsorbent granules can effectively adsorb lead and are free of environment pollution; the adsorbent is low in manufacturing cost and convenient to use.

The invention belongs to the technical field of vulcanized paper and particularly discloses high-tinting-strength green vulcanized paper for abrasive discs. The high-tinting-strength green vulcanized paper is prepared from, by weight, 100-120 parts of cotton fibers, 40-70 parts of wood pulp cellulose, 4-12 parts of an inorganic composite pigment, 0.8-1.2 parts of a dispersing agent, 2-4 parts of water-soluble chitosan, 2-6 parts of an insulation reinforcing agent, 3-7 parts of a heatproof reinforcing agent and 1-3 parts of a setting agent. The inorganic composite pigment is prepared from glauconite, green serpentine and a cobalt green pigment, a particle size range of glauconite and green serpentine is 0.1-1nm, and glauconite and green serpentine are calcined for 2-3h at 500-600DEG C before use. The green vulcanized paper for the abrasive discs is high in tinting strength, less prone to fading, moisture absorption and deformation, great in heatproof performance, insulating, flame retardant and long in service life, and prepared abrasive discs are high in processing precision due to great surface fineness of the green vulcanized paper.

The invention relates to an oil field produced water treatment filtration tank gas-water backwash regeneration process. The process comprises a gas washing process and a water washing process. First, the filtering material in the filtration tank is subjected to gas backwash with 2 gas gradients according to a gas washing process, and the filtering material in the filtration tank is subjected to water backwash with 1 water gradient. The gas washing process sequentially adopts an air compressor, an air pressure regulation tank, a gas flow rate controlling valve set, a single-tank gas inlet switching valve, the filtration tank, a backwash water discharge valve, and a low-level recovery water tank. The water washing process sequentially adopts a backwash variable-frequency water pump, a water flow rate regulation valve set, a single-tank backwash water inlet switch valve, the filtration tank, a backwash water discharge valve, and a backwash recovery water tank. With the process, regeneration of particulate filtering materials in single-layer quartz filtration tank, single-layer magnetite filtration tank, quartz-magnetite double-layer filtering material filtration tank, glauconite-magnetite double-layer filtering material filtration tank, and the like in oil field produced water treatment processes can be effectively realized.
