Metal Mesh: Water treatment technology to re-aeration oxygen technology Which strong?

In recent years, China's sewage treatment technology continues to tackle difficult problems, the water environment treatment technology is increasingly mature. Now the water environment management technology not only completed a variety of aeration technology further innovation, but also make aeration technology in surface water environment management has been more widely used. A variety of aeration and aerobics boarded the market stage, which is more significant role in the governance of the water environment? And look at the text of the comparative analysis.

Water treatment technology to re-aeration oxygen technology Which strong?

At present, China's water environment management technology mainly includes physical technology, chemical technology, biotechnology and the application of integrated technology. Among them, aeration aeration technology is the core technology in physical technology. Although aeration is a very mature technology and product in sewage treatment, urban surface water bodies in rivers, landscape water bodies and reservoirs have the problems of large area, different shapes and difficulties in electricity supply, resulting in the conventional aeration technology and products in wastewater treatment Difficult to apply to surface water environment management. According to the survey, China's water environment management company has developed a number of aeration and aeration products suitable for surface water environment through technology introduction, research and development and has successfully applied to many projects.

With the acceleration of urban development, urban water pollution has become a prominent problem and a governance problem in our country. Urban rivers and landscape water bodies are mostly closed or poorly liquid closed water bodies. They have the characteristics of small water area, easy pollution, small water environment capacity and poor self-purification ability of water bodies. Coupled with external pollution, they can easily cause eutrophication of water bodies and Black and smelly phenomenon. Aeration aeration technology to improve dissolved oxygen in water to restore the water environment and the treatment of pollutants in water is a common means of water environment management.

Aerobic aeration technology category

According to the bubble size, the role of the principle and the different energy sources, currently applied to the project aeration technology and products are mainly the following three. One is a micro-nano aerator, which is made by the highly dispersed gas phase and liquid phase to produce micron-sized bubbles and nano-bubbles with diameters less than 3 [mu] m. Micro-nano bubbles with long survival time, large specific surface area, high interface activity, with a special charge with the physical and chemical properties. One is a clean energy aerator, such as solar aerator, wind aerator, and dual-use aerator scenery. This aerator generally use clean energy to drive the motor to the mechanical components of the atmosphere to achieve oxygen or blast, oxygen transmission. One is to push the flow of aerator, according to the need to create a flow in certain areas, to enhance water circulation, while both aeration. From the oxygen effect, micro-nano bubble aerator the best, but subject to the role of small size, power consumption and other issues.

Two kinds of aeration aeration theory and products

Currently in academia, there are mainly two theories about oxygen enrichment and aeration in water environment. One is the theory of "living water", that is, living water does not die. As long as water is flowing, the water body can maintain a relatively good water quality by self-purification capability. This theory has been well used in aeration technology products in the United States. Such as the United States solarbee aerator, in rivers, reservoirs and sewage treatment plant aeration tank, tap water large-scale piggy banks have been widely used. At present, the product has been introduced and digested by Nanjing's leading environmental protection, developed a series of Ai Pu IPOCH solar aerator.

The other is to respect nature, do not change the water environment theory. This theory holds that each layer of natural water has different ecological environment. For example, different types of oxygen, such as algae, microorganisms and fish, can not destroy the natural environment because of the water environment management. This theory has been applied to aeration technology products in Japan. Such as Japan NANOMAIZU micro-bubble technology, Songjiang Civil Engineering and Japan Civil Engineering Institute of deep aeration, etc., only through the underlying oxygen-rich physical technology, without changing the status of the middle and upper waters.

Japan's two products, has also been the introduction of domestic companies to absorb. Such as Nanjing Jinhe Water Environment Co., Ltd. micro and nano bubble generator, as well as water purification company in Jiangsu Yixing WEP. Domestic research and development of some aeration technology, both theories have applications. More typical is due to the inconvenience of electricity in the water environment management, some research institutes, water environment management companies developed a clean energy-based aerator, some of the products in the country's science and technology programs, such as water has been applied , But not yet industrialized.

Application of aeration aeration technology in our country

Whether it is micro-nano-aeration technology, or solar energy, wind aeration technology and conventional push aeration technology, water environment in our country have been widely used.

In large reservoirs and drinking water sources, such as Nanjing Lishui Convenient Reservoir, Dongguan Matsushima Reservoir, Beijing Guanting Reservoir, Yixing Longzhu Reservoir, using a solar energy aerator, WEP ecological water environment repair system to prevent water eutrophication And improve water quality. In some eutrophic lakes, such as Taihu Lake, Yunnan Dianchi Lake, Wuli Lake in Wuxi, Wenzhou, Yokogawa, Po, Nanjing Lixuhe black stinking water, as well as Shanghai Yuyuan, Beijing Beihai Park and other urban landscape water are used Aeration aeration technology.

Aerobic aeration technology product parameters comparison

In the water environment management, I believe that the main parameters to measure the performance of aerated aeration technology products: oxygen delivery capacity, power consumption and spread of the range. As far as I know we may wish to MBO micro-nano bubble generator, IPOCH solar aerator, OBAO solar water aerator, WEP ecological water environment repair system, wind and solar complementary aeration system to have patented technology and have been applied comparing.

MBO micro-nano bubble generator: Japan NANOMAIZU technology, authorized production in China (Nanjing Jin Wo), the core components imported from Japan, in accordance with the Japanese side of the technical standards for assembly production.

IPOCH solar aerator: US SOLARBEE technology products digestion and absorption in China, Nanjing has applied for the leading environmental protection patent and production of China.

OBAO Yang solar-powered aerator: The technical principle is still the United States SOLARBEE technology, the Shanghai EU environmental production.

WEP Eco-Aquatic Remediation System: The deep aeration technology developed by Japan's Songjiang Civil Engineering Co., Ltd. and the Institute of Civil Engineering authorizes Jiangsu Zhongyi Water Body Rehabilitation to be manufactured in China. The core components are imported from Japan and are currently patented domestically.

Scenery complementary aeration system: the achievements of the national water special subject, the Ministry of Environmental Protection Nanjing Environmental Protection Research Institute, the principle of technology for the traditional blast aeration equipment, but with clean energy instead of electricity.

From the perspective of oxygen delivery, MBO micro-nano bubble
