Biofilm Inner Mongolia Wastewater Treatment Equipment Features Brief introduction: One of the more common treatment equipment in the biofilm wastewater treatment equipment market, some people have insufficient understanding of the biofilm method. Today, Mengyuan Water will introduce the biofilm wastewater treatment equipment to everyone. specialty. It is a type of wastewater aerobic biological treatment technology parallel to the activated sludge method. It is a fixed membrane method. It is the artificialization and strengthening of the self-purification process of sewage water. It mainly removes soluble and colloidal organic pollutants in wastewater. Treatment technologies include biological filters (common biological filters, high-load biological filters, tower biological filters), biological turntables, biological contact oxidation equipment, and biological fluidized beds.
A microorganism growth and accumulation carrier (commonly referred to as a filler) is set in the sewage treatment structure. Under the condition of oxygenation, microorganisms gather on the surface of the filler to form a biofilm. After the oxygenation (the oxygenation device is treated with water by an aeration fan and aeration) When the sewage flows through the filler at a certain flow rate, the microorganisms in the biofilm absorb and decompose organic matters in the water. Inner Mongolia sewage treatment makes the sewage purified, and the microorganisms also multiply, and the biofilm is thickened. When the biofilm grows to a certain thickness, the oxygen diffused into the interior of the biofilm is limited, and its surface is still aerobic, while the inner layer will be anoxic or even anaerobic, and eventually cause the biofilm to fall off. Subsequently, new biofilms will continue to grow on the surface of the filler, which will be repeated to make the sewage purified.
1. Strong adsorption capacity: The domestic sewage is rich in a large amount of organic components. The Inner Mongolia wastewater treatment biofilm method relies on a microbial membrane fixed on the surface of the carrier to degrade organic matter, because the microbial cells can be firmly on the surface of any suitable carrier in the water environment. Attachment, growth and reproduction of the ground, the extracellular polymers extending from the inside to the outside make the microbial cells form a fibrous tangled structure, so the biofilm usually has a pore-like structure and has strong adsorption properties.
2. Mature technology: The biofilm is attached to the surface of the carrier and is a highly hydrophilic substance. Under the condition that the sewage is constantly flowing, there is always a layer of water attached to the outside. Sewage treatment equipment can produce high-density bacteria communities by cultivating bacteria. A large number of microorganisms and micro-animals grow and reproduce on the surface and inside of the membrane, forming a food chain composed of organic pollutants → bacteria → protozoa (metazoan). Biofilms are composed of bacteria, fungi, algae, protozoa, metazoans, and other biological communities visible to the naked eye.
3. Stable and efficient: When the sewage flows over the surface of the carrier, the organic pollutants in the sewage are adsorbed by the microorganisms in the biofilm. The Inner Mongolia wastewater is treated and diffused into the biofilm through oxygen, and biological oxidation occurs in the membrane. Degradation of organic matter. Aerobic and facultative microorganisms grow on the surface layer of the biofilm, while microorganisms in the inner layer of the biofilm are often in an anaerobic state. When the biofilm gradually thickens and the thickness of the anaerobic layer exceeds the aerobic layer, the biofilm And the new biofilm will be regenerated on the surface of the carrier, and the cycle of the biofilm is updated to maintain the normal operation of the biofilm reactor of the sewage treatment equipment.
The biomembrane wastewater treatment equipment has more control over the reaction process, and the technology of wastewater treatment in Inner Mongolia is easier to grasp. From the perspective of input cost, it also has certain advantages, and will not cause excessive economic burden.
