Description

Bionic aquatic weed for river regulation

Technical Field

The utility model relates to a bionical pasture and water technical field, concretely relates to bionical pasture and water for river course is administered.

Background

At present, the current situation of river pollution and eye surprise in China cause that water shortage and accidents caused by pollution continuously occur, so that the factory is stopped, the agricultural yield is reduced, and even the factory is completely harvested. The treatment of river channels is already slow. In the river course treatment process, the most common and most important mode is ecological treatment by aeration reoxygenation, dissolved oxygen in a water body is improved mainly by aeration, according to the characteristics of microorganisms, organic pollutants are degraded into biochemically harmless carbon dioxide, water and microorganism cells, ammonia nitrogen generates nitrate nitrogen in an aerobic process, then nitrogen is generated in an anoxic and anaerobic environment, phosphorus in the water body is taken as an essential element of a synthetic cell to participate in the synthesis and energy metabolism of the cell and is enriched in the cell, and a sulfur-containing compound generates sulfate radicals, so that the pollutant is removed. The formed biological sludge can fall off and be taken away by water or be sent to a solid waste treatment area through manual cleaning. In the river treatment process, as the water body flows, formed microorganisms for removing pollutants can be continuously formed along with the flow of the water body, but the process is also influenced by other environments, such as pollution degree, water flow velocity, temperature and the like, and simultaneously generated adaptive microorganisms can be continuously taken away along with the flow of the water body, so that the microorganisms are easily interfered in the treatment process and the treatment stability is poor.

The biomembrane method is characterized in that a large number of microorganisms (aerobic bacteria, anaerobic bacteria, facultative bacteria, fungi, protozoa, algae and the like) are attached to the surface of a medium filter material to form a biomembrane, and after sewage is contacted with the biomembrane, the microorganisms in the biomembrane take organic pollutants in the sewage as nutrient substances, degrade organic substances in the metabolic process, and simultaneously proliferate the microorganisms to purify the sewage. Wherein, the inert carrier for providing the attachment growth of the microorganism is called as a filter material or a filler. The biofilm method has some special advantages, such as no sludge backflow, easy operation management, no sludge bulking problem, easy microorganism survival, stable operation and the like. Therefore, the technology of water treatment by using a biofilm is certainly applied to a wide range of industries. The basic conditions for biofilms are (1) the attachment of appropriate microorganisms must be enabled; (2) a large specific surface area is required; (3) a large void fraction is necessary; (4) strong biological, chemical reaction stability and enough mechanical strength are required, and the specific gravity difference with water is small; (5) the price is moderate, and the product can be stably provided.

The biological contact material with the advantages and conditions has greatly different wastewater treatment performance due to different structures of various contact materials. The bionic aquatic weed has all the basic conditions, has other unique advantages and is a high-quality contact material which can completely meet the requirements of various wastewater treatments.
