Biological streamers (also known as biological belts, ecological belts) are new types of fillers, oxygenated by aeration, and block submerged installations to realize biological contact oxidation methods and achieve the purpose of treating river pollution. It is a part of sewage treatment. new technology. It is especially suitable for water purification of rivers and tributaries with serious pollution. It is also an enhanced purification technology that pollutes rivers.
The biological streamer technology is used to build dispersed sewage treatment facilities in the river. The microorganisms are generally negatively charged, and the surface of the streamer is cross-linked with a layer of positively charged material, which makes the surface of the streamer positive, which makes it easier for bacteria to attach and grow, and mold hanging is faster.
Through aeration and oxygenation, many microorganisms can be adsorbed or attached to the streamers more effectively. These microorganisms can grow with organic matter in the water, so as to achieve the purpose of consuming harmful substances and purifying water quality.
Each square meter of biological streamers can provide a surface area of about 250 square meters. 0.7-1.2kg of dissolved oxygen removes about 1.0kg of COD and about 0.4kg of ammonia nitrogen.
YFNB series wind energy aeration is a new energy-saving and environmentally friendly product. It is a complete aeration system. It uses wind power generation technology and magnetic levitation technology to directly drive the compressor through the blades to produce oil-free clean compressed gas.
Compared with traditional electric energy aeration technology and diesel generator aeration technology, it has no energy consumption, no pollution to the environment, easy installation and use, and long-term operation.
This product is widely used in aeration and oxygenation in rivers, lakes, reservoirs, constructed wetlands, sewage treatment plants, aquaculture, and can also be used for long-distance wind water delivery and water extraction.
Obtained the national utility model patent product (patent name: a wind aeration air supply machine; patent number: ZL 2013 2 0568398.X).
