one. Product Introduction

1. Introduction

The RAUBIOXON PLUS DISC 260 aeration system consists of silicone rubber membranes, support disks, snap rings, saddle connections, and other components. When oxygenation and aeration are carried out, compressed air diffuses into the water through the microporous gas layer to achieve the purpose of oxygenation and aeration.

2.2 Advantages of Silicone Rubber Aeration Disk

-Silicone membrane is corrosion resistant and aging resistant, with long service life and stable operation

-The flexible point system design ensures that the micropores on the membrane automatically close when the gas supply is stopped, preventing wastewater from entering the tray

-Perforation will not block, suitable for both continuous operation and intermittent operation

-Good aeration characteristics, high oxygen utilization rate and power efficiency

-The volume of bubbles, uniform distribution of bubbles

-Quick and easy installation method, saving a lot of accessories

-After passing through the aeration disc, the average diameter of the bubbles1.0~2.0mm.

-Under normal usage conditions, maintain a high oxygen transfer rate during the service life.

-Use a condensate drainage device to remove the accumulated water in the air distribution pipe.

three. Design and Structure

a. The aeration disc provided by our company can adapt to work under different sewage quality and temperature conditions, meet the needs of sewage biochemical treatment in the aerobic zone of the biochemical tank, effectively diffuse the air from the blower evenly into the water, and maintain stable oxygenation effect and efficiency for a long time. When the gas supply is stopped, the aeration hole can be effectively closed.

b. The microporous mode aeration disc meets the following requirements:

-Single disk outer diameter 270mm.

-The service life of the microporous mode aeration disc: not less than5Year (municipal wastewater).

c. The microporous aeration disc is disc-shaped and attached with a silicone rubber membranePPOn the support plate made of high-strength materialPPMaterial fixing ring fixation.

d. The rubber film is made of German imported silicone rubber material. The membrane is made using injection molding technology; The membrane punching is mechanical punching, with square holes perpendicular to the membrane pattern.

e. The air entering the aeration disc must be purified to meet the requirements of long-term continuous use or disuse before being put back into use, without causing blockage of micropores and backflow of mixed liquid.

f. The connection between the aeration disc and the air distribution pipe adopts a saddle interface, which does not require additional bolt fastening, avoiding the possibility of detachment during operation caused by different tightening forces of double bolts and saving installation time.

g. The surfaces of each component on the microporous aeration disc are clean and smooth, without scratches, bubbles, pores, inclusions, spots, wrinkles, or sharp edges.

h. The aeration disc provided by our company is resistant to corrosion from urban sewage, high temperature, and acid and alkali.

four. Installation and debugging

The company will provide professional personnel to guide installation and debugging to ensure the quality of installation.

Before installation, it is necessary to check the dimensions of the civil structures.

Test the equipment after installation to ensure quality.

Taicang Factory.In order to provide timely and effective services to China, Southeast Asia, and various countries in Australia, German Ruihao Company invested 200 million yuan in 2008 to establish a factory in Taicang, Jiangsu, China, fundamentally solving the problem of long supply times. At the same time, as the factory in China is a wholly-owned subsidiary of Germany's Ruihao, its raw material supply and production equipment are all from Germany, and the production process, inspection standards, personnel management, and even logistics and distribution all strictly comply with Germany's Ruihao's requirements. It not only maintains the quality of finished products, but also meets the needs of project progress in terms of supply time. Today's Ruihao has not only become a leader in product quality, but also driven the development of the aeration industry in various aspects such as design, research and development, and service.

The textile printing and dyeing industry is a major emitter of industrial wastewater, which mainly contains pollutants, oils, salts on textile fibers, as well as various pulp, dyes, surfactants, additives, acids and bases added during the processing. The characteristics of wastewater are high concentration of organic matter, complex composition, deep and variable color, large pH changes, large variations in water quantity and quality, high COD, poor biodegradability, etc. It is difficult to treat industrial wastewater.

The key to the coagulation treatment of printing and dyeing wastewater lies in the selection of appropriate coagulants. Conventional coagulants suitable for printing and dyeing wastewater treatment mainly include polyaluminum chloride, aluminum sulfate, iron sulfate, and ferric chloride in the early stage, and cationic polyacrylamide in the later stage. These coagulants have significant effects in treating some non water soluble dye wastewater, such as dispersed dyes, reducing dyes, sulfurized dyes, COD and chromaticity removal rates, which are very high.

1. In the textile industry, polyacrylamide flocculant is used as a sizing and finishing agent for fabric post-treatment, which can generate a soft, wrinkle resistant, and mold resistant protective layer.

2. Coagulants as post-treatment agents can prevent static electricity and flame retardancy in fabrics.

3. When used as a printing and dyeing additive, it can enhance the adhesion and brightness of the product, and can also serve as a non silicone polymer stabilizer for bleaching.

4. It has an efficient purification effect on sewage discharge in the printing and dyeing textile industry.

In recent years, biological treatment technology has been adopted for wastewater treatment in the textile printing and dyeing industry, achieving good treatment results.

1. Anaerobic biological treatment of textile printing and dyeing wastewater:

The anaerobic decomposition of organic matter involves two stages: acidic fermentation and alkaline fermentation. In the acidic fermentation stage, the organic matter in the textile factory printing and dyeing wastewater is decomposed into simpler organic matter under the action of acid producing bacteria. In the alkaline fermentation stage, due to the neutralization effect of NH3 on organic acids, the pH value gradually increases, and methane bacteria begin to move, decomposing the organic acids and alcohols produced in the previous stage into methane and carbon dioxide.

2. Aerobic biological treatment of textile printing and dyeing wastewater:

In the treatment of textile printing and dyeing wastewater, dissolved organic matter is first adsorbed by bacteria during aerobic decomposition. Solid and colloidal organic matter is then hydrolyzed into soluble substances by external enzymes secreted by bacteria and infiltrates into bacterial cells. The dissolved organic matter entering the cell is partially oxidized and decomposed into simple inorganic substances under the action of internal enzymes, while releasing energy.

Generally speaking, using a combination of anaerobic and aerobic processes to treat textile printing and dyeing wastewater can save energy and reduce consumption, resulting in better results.
