Combining online observation and single factor method, the formation process of the surface features of the polished area was studied. The experimental results showed that the surface morphology of the polished area showed a W-shaped bowl structure in the vertical jet machining, and an eccentric bowl structure in the crescent shape in the oblique jet machining.Compared with the abrasive water jet machining effect, it is found that the W shape and crescent shape characteristics of the polishing region of MASJP are relatively flat, the smooth surface is larger and the surface quality is higher. 4. When applying nozzle with different outlet shapes in MASJP, it is found that the fluid ejected from the cylindrical nozzle flows out along the direction of the jet and does not disperse. The processing area of the fan-shaped nozzle is large, the polishing area is approximately a rectangle, and the removal depth near the nozzle is larger.Hollow conical nozzle processing finished parts, the polishing area formed a hollow circle, the central part of the removal of less, the circumference of the removal of deep;The removal depth of the polishing area decreases gradually from the center to the circumference after the finished piece is processed by the solid conical nozzle. 5, the workpiece surface profile and material removal depth with the selection of polishing slurry composition changes.With the increase of abrasive concentration, the material removal depth increases, which is roughly in a proportional relationship.With the increase of abrasive particle size, the material removal depth also increases.

At present, the organic pollution of drinking water source is relatively serious. The organic pollutants themselves are not only highly toxic, but also may generate halogenated disinfection by-products (DBPs) after chlorination disinfection. Meanwhile, the existence of organic compounds will reduce the biological stability of drinking water and lead to the secondary reproduction of microorganisms in the pipe network. Therefore, it is important to reduce the content of organic pollutants in drinking water. Conventional water treatment process has low removal efficiency for organic pollutants, so it is imperative to seek economic and efficient treatment technology. On the basis of giving full play to the advantages of ozone oxidation to remove organic matter, ozone catalytic oxidation technology can induce the formation of highly oxidizing hydroxyl radical (-Oh), which can effectively remove trace organic pollutants that are difficult to degrade in water and reduce the content of ozone oxidation by-products. It is a kind of water treatment method with great prospect.activated carbon for gold recovery  Laboratory studies have shown that ceramic honeycomb activated carbon catalytic ozone oxidation technology and removal of trace organic matter in water has more obvious advantages, but the catalytic oxidation and active carbon process characteristics to be in-depth study, therefore the pilot was investigated through honeycomb ceramic catalytic ozonation and activated carbon catalytic ozonation and activated carbon filter combination process operation characteristics. activated carbon wholesale

Activated carbon (AC) is a kind of porous carbon material with developed pore structure and large specific surface area, which is prepared by using biological organic matter (such as wood, coke, petroleum coke, coal and various nut shells, etc.). It is a kind of high quality adsorbent.activated carbon pellets wholesale   With the development of industry, its application is more and more extensive.www.powdered-activated-carbon.com  At present, it has been widely used in the field of environmental protection, food industry and medicine. The granular activated carbon with high strength was prepared by heating wood phosphate mixture at low temperature and using tar generated during its pyrolysis as binder. In this paper, the process conditions and plasticizing mechanism of granular activated carbon prepared by phosphoric acid were studied, which provided scientific data and theoretical basis for the preparation of high strength granular activated carbon. Fir chip as the raw materials, H - POs as activator, using single factor analysis and orthogonal experimental design method, this paper discusses the influence granular activated carbon pore structure and the iodine adsorption value, methylene blue and strength of various preparation factors, determine the optimum process conditions of preparation of granular activated carbon phosphoric acid, phosphoric acid concentration is 70%, dipping 180%, kneading temperature is 170 ℃, for 60 min kneading time, activation temperature is 350 ℃, the activation time of 210 min. The iodine adsorption value, methylene blue adsorption value, strength and BET specific surface area of GAC were 1020.04mGG, 225mg/g, 88.73% and 1486.48m2/g respectively. The experimental results show that the impregnation ratio and carbon activation temperature have great effects on the adsorption performance of GAC, while the kneading temperature and impregnation ratio have great effects on the strength of GAC. Because the strength of GAC decreases with the increase of impregnation ratio, and the decrease range is large, so the preparation of GAC with compound activator is proposed. The results show that the composite activator can reduce the impregnation ratio of phosphoric acid to wood chips and improve the strength of granular activated carbon. At the same time, the composite activator can improve the adsorption performance of GAC. Therefore, granular activated carbon with good adsorption performance and high strength can be prepared by this method.
