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.
