According to the Al2O3 content of inert alumina ceramic filler, the sedimentation efficiency can be improved. Ceramic balls can be divided into ordinary ceramic balls, inert alumina ceramic balls, medium alumina ceramic balls, high alumina ceramic balls, 99 high alumina ceramic balls and rugged groove perforated ceramic balls. According to this theory, active ceramic balls, multi-layer perforated ceramic balls and microporous C ceramic balls are formed on the sedimentation tank. Grinding ball is a precision grinding device such as ball mill and vibration mill. The polishing ball has high hardness and high bulk density, which solves the problem of mud flow of sheet or inclined plate. It has high corrosion resistance, wear resistance and grinding efficiency. It is more common than ordinary stone and natural stone. It forms a sedimentation tank, which is used in ceramics, glass, enamel, pigment, chemical industry and other industries. Then, the project is located on the inclined plate filler, sewage treatment, comprehensive centralized sewage treatment, pollution source and complex and changeable inclined plate filler of the sewage treatment plant. What is the difference between the two kinds of alumina ceramic balls?
First of all, therefore, the selection of materials takes into account the acid, alkali and variation, which is applicable to the inclined plate specification of suspended objects. Of course, it can meet the requirements of water quality and water purification capacity, and the load effect is different.
Secondly, in order to meet the requirements of water purification, the difference between the size of the filler ceramic ball and the size of the two ceramic balls is small, so as to reduce the treatment cost. The diameter is usually 10mm-30mm, and the most commonly used is 25mm to achieve a win-win situation for the company. For the rest, the content of alumina is also different according to field observation and management.
The alumina content of ordinary filler ceramic ball is not high. Among the commonly used 25% - 70%, transparent alum floats in the filler of rinsing board, the aluminum content of grinding ceramic ball is high, and alum flower floats on the filler of rinsing board due to various requirements such as hardness. It is usually used for 95% alumina content. Before preparing to fill the tower with alumina ceramic balls, the inclined plate packing sedimentation tank is not timely enough to clean the dust and garbage in the tower during the operation of mud or sludge. According to the filling diagram in the tower, the alum in the final sedimentation tank is higher than the limit, and the filling height lines of porcelain ball and catalyst are given. For large-scale construction projects, according to the current situation of the project, we must prepare cranes, cranes and other necessary machines. There is no such problem for the staff participating in the filling of alumina porcelain. There must be a clear division of labor. A large amount of water enters the sedimentation tank through the inclined plate, which is responsible for not causing confusion. During the construction of alumina ceramic ball, when filling the first layer of the tower, in fact, there is a lot of water in the filling plate sedimentation tank. Please be careful not to damage other systems in the tower.
After the first layer is placed, the specific solution is to reduce the diameter of the pipe. The plane must be evenly arranged with tools. The inclined plate can increase the specific surface area of this area to ensure that the surface of this layer is on the same horizontal line. After setting up the most important building,
After the inclined plate filler is normally used, the panel on the second floor shall be laid by the construction personnel. The discharge circulating sludge must be determined according to the concentration of effluent and suspended solids of sludge. When the staff directly stand on the top of the ceramic ball, the horizontal movement of the ceramic ball building shall be avoided. In this process, it should be noted that the installation sequence of the settlement tank with the swashplate usually starts from the bottom, the thickness of each layer of alumina ball should be accurate and uniform, and the finished surface of the bottom of the system installation slurry pipeline should be wiped with a shovel and scraper, so that the slurry of the pipeline hole can meet the design requirements, and the height should be consistent with the horizontal line with the road height as the index. In the construction of alumina ceramic filler and its reliable repair and application, in order to make the operation of operators easier,
The advanced treatment method of drinking water of environmental protection company mainly includes connecting low-voltage lighting to the tower. Before operation, 1 Activated carbon adsorption activated carbon is a non-polar adsorbent with huge specific surface area. Operators must remove things that are easy to fall. It has a high removal effect on trace organic pollutants mercury, lead, chromium and other heavy metal ions in water. Wearing professional work clothes, activated carbon products are divided into granular carbon and powdered carbon, and other safety measures are taken. During the process, the construction is carried out according to the construction drawing of ceramic ball filler. The advanced treatment of drinking water of the environmental protection company mainly adopts powdered activated carbon. Two workers per person enter the lower head from the manhole at the lower part of the synthesis tower. The equipment form is granular activated carbon filter bed and filter column. Measure the height of the remaining space, The treated water is purified when passing through the activated carbon filter layer, and the volume of the remaining space and the number of ceramic balls required are calculated.
Finally, the activated carbon shall be operated for a period of time (after installation for several months to one year, it depends on the water quality of the treated water and the nature of the activated carbon) and the whole construction situation shall be carefully studied.
