上海松夏shock absorberThe limited company introduces the DN600 sewage treatment plant to yourubberjointShipping photos, the following pressure is PN10, mainly used for sewage treatment plant projects, using medium: sewage, rubber needs to be corrosion-resistant.

*Wastewater treatment plant:

A sewage treatment plant is a place where the wastewater discharged from a pollution source, due to its high total amount or concentration of pollutants, does not meet the discharge standards or environmental capacity requirements, thereby reducing the water environment quality and functional goals. Therefore, it is necessary to undergo artificial reinforcement treatment. *It is generally divided into urban centralized sewage treatment plants and decentralized sewage treatment plants for various pollution sources, and after treatment, it is discharged into water bodies or urban pipelines. Sometimes, in order to recycle and reuse wastewater resources, it is necessary to improve the quality of the treated effluent by constructing wastewater reuse or recycling wastewater treatment plants.

There are various commonly used treatment processes in sewage treatment plants A combination of optimized water treatment methods, including various physical, chemical, and biological methods, requiring advanced technology, economic rationality, and cost Province. When designing, it is necessary to implement the current situation Various construction guidelines and policies. Therefore, in terms of treatment depth, sewage treatment plants may be * *, 2 *, 3 * or deep treatment. The design of sewage treatment plants includes the plan and elevation design of various structures, ancillary buildings, pipelines for different treatments, as well as the design of roads, greening, pipeline integration, plant water supply and drainage, sludge disposal, and automation of treatment system management to ensure that the sewage treatment plant achieves stable treatment effects, meets design requirements, is easy to operate and manage, has advanced technology, and saves investment and operating costs.

At present, the development and progress of my sewage treatment industry are relatively late. Before the reform and opening up, my demand for sewage treatment was mainly for industrial and preventive purposes End use is the main focus. After the reform and opening up, the rapid development of the economy and the significant improvement of people's living standards have driven the demand for sewage treatment. After entering the 1990s, the sewage treatment industry entered a period of rapid development, and the growth rate of sewage treatment demand was much higher than the global level.

The content of trial operation of sewage treatment project

(1) By conducting trial runs to inspect the quality of civil engineering, equipment, and installation projects, establish archival materials for relevant equipment, and provide suggestions for the design rationality and operational precautions of related machinery, equipment, and instruments.

(2) Operate certain general or specialized equipment under load and test its capabilities. Such as the flow rate and head of the water pump, the air volume, pressure, temperature, noise, and vibration of the blower, the oxygenation capacity or utilization rate of the aeration equipment, the operational stability of the mud scraping (discharging) machinery, the effectiveness of the protective device, and the mud scraping (discharging) effect.

It is understood that in today's world where natural freshwater resources have been fully developed and natural disasters are increasingly frequent, water shortage has posed a serious threat to the economy and citizens' lives of many cities around the world. The water shortage crisis has become a reality we are facing, and an important way to solve urban water shortage problems should be to turn urban sewage into urban water sources. Urban sewage can be obtained nearby, with stable sources and easy collection, making it a reliable and stable water source. After purification, urban sewage can be reused mainly as municipal greening, landscape water, and industrial water. The urban sewage regeneration and reuse project includes sewage collection system, sewage purification treatment technology and its system, effluent transmission and distribution system, reuse water application technology and monitoring system. The key lies in the technology and system of sewage purification and regeneration. The process of sewage purification treatment should be simple and reliable, and the investment and operating costs should be affordable for the city's economic strength. The water quality of the treated effluent should meet the requirements for reuse.

2、 Rubber joint:

Application scope and advantages of DN600 rubber joint:

1. With excellent comprehensive performance, DN600 rubber joints are widely used in basic engineering such as chemical, construction, water supply, drainage, petroleum, light and heavy industries, refrigeration, sanitation, plumbing, fire protection, and electricity Do not apply to pipelines with high vibration and frequent changes in temperature.

2. Rubber joints can be used in pipelines for cold water, hot water, compressed air, natural gas, etc.

3DN600 rubber joint The design, innovative structure, and excellent sealing performance of. have solved the problems of pipeline rupture and damage caused by thermal expansion and contraction, effectively improving the service life of pipelines and protecting equipment.

DN600 rubber joint Point: It is made of a mixture of inner rubber layers, with smooth and seamless marks. The label adopts vulcanization process and is combined with the product. It has high pressure resistance, good elasticity, large displacement, balanced pipeline deviation, good absorption of vibration, good noise reduction effect, and easy installation Point.

Requirements for the use of DN600 rubber joints: material type Rubber with good sealing performance, light weight, easy installation and maintenance, long service life, but avoid contact with sharp metal instruments to prevent puncturing the sphere. If the rubber joint is used overhead, an elastic bracket can be equipped. When installing, the bolts should be tightened diagonally. If the pressure of the rubber joint pipeline is too high, it should be used Limit the bolts to connect the flanges at both ends starting from *.

The function of DN600 rubber joint: It can greatly reduce the vibration and noise of pipeline systems, fundamentally solve the problems of interface displacement, axial expansion and contraction, and different concentricity of various pipelines. According to different materials, rubber joints can be made into acid resistant, alkali resistant, corrosion-resistant, oil resistant, heat-resistant and other varieties, suitable for various media and environments.
