Multifunctional water purification carrier system

technical field

The utility model relates to a multifunctional water purification carrier system, which belongs to the technical field of water pollution control and ecological engineering

Background technique

In the past ten years, my country's water pollution and eutrophication have intensified. A series of environmental and ecological problems such as drinking water safety and ecological security caused by water pollution and eutrophication have become a bottleneck restricting my country's social and economic development. Therefore, it is imminent to strengthen the protection and management of water resources in rivers, lakes and reservoirs in our country. the

At present, the research hotspots of eutrophication control in lake water are concentrated on the control technology of nutrient salt, such as nutrient absorption and restoration of aquatic higher plants, immobilized microorganism technology, etc. the

In the restoration technology of aquatic higher plants, local indigenous species such as floating plants, emergent plants and submerged plants are mainly used. Through the growth and metabolism of plants themselves, a large amount of nutrients in water bodies such as nitrogen and phosphorus are absorbed, suspended particles are adsorbed, and algae growth is inhibited. enriched in heavy metals. the

Immobilized microorganism technology is a technology that immobilizes microorganisms on a carrier to make them highly dense and maintain their biological activity. Immobilized microorganism technology has also attracted more and more attention. the

The in-situ treatment of river and lake water quality and restoration of ecosystem by biofilm method has become the preferred method in immobilized microbial technology because of its good treatment effect, low cost and no secondary pollution. Since it was discovered that the biofilm growing on the pebbles has a repairing effect on polluted river water, biofilm water purification technology has entered the stage of substantive research and application. the

Eco-based products were invented by Japanese scientist Professor Akira Kojima, and in 2006, they were popularized and applied to the fields of water ecological environment restoration and water pollution prevention all over the world. They are currently the world's leading natural ecological water treatment technology products. the

Therefore, the specific surface area is large, the pores are developed, the adsorption performance is high, and the desorption speed is fast. It can be used repeatedly for more than ten years. Each gram of fiber of the ecological base can provide a maximum attachment surface area of about 950-1500 square meters for the growth and reproduction of microorganisms and algae in water, thereby realizing the basic conditions for efficient microbial communities. This polymer fiber ecological base does not rust, mold and rot in water, and has affinity with microorganisms, so it is a good material for restoring the ecological environment of polluted water. the

Place the fiber ecological base in the water and absorb various aquatic organisms in the water to its surface. Over time, the surface of the ecological base will attach and grow microorganisms and algae. These microorganisms and algae play a role in biological filtration and biological conversion of eutrophic water bodies. Key role. Attached growth microorganisms and algae decompose organic pollutants in the water body and provide C source for phytoplankton photosynthesis, promote the rapid reproduction of phytoplankton and absorb and utilize a large amount of N and P elements in the water body, so as to reduce the nutrient content in the water and lighten the water body. The purpose of eutrophication. the

Relying on the nitrification and denitrification of microorganisms, the absorption of plants and the adsorption of nitrogen, heavy metal elements, and toxic substances in water bodies by ecological substrates, it can be used for BOD, COD, TOC, nitrogen, phosphorus, color, odor, oil, phenol, organic The removal of poisons, residual chlorine, heavy metals, etc., plays a role in purifying water quality. the

The utility model has the characteristics of simple structure, easy operation, strong mobility, can be used in water areas of different scales, sewage treatment systems, and family fish tanks, durable, strong anti-dumping, good buoyancy, beautiful appearance and low cost. The combination of ecological floating island and carbon fiber ecological base technology is widely used in water treatment. It can be used for the removal of BOD, COD, TOC, nitrogen, phosphorus, color, odor, oil, phenol, toxic substances, residual chlorine, heavy metals, etc. It is the preferred choice for water pollution control in river basins and lake eutrophication prevention and control. the

Use microbial nitrification-denitrification to remove part of nitrogen and phosphorus nutrients, and expand the original aerobic-anaerobic, nitrification-denitrification conditions dominated by the water-soil interface to the entire water body. So as to gradually restore the good ecosystem of the water body and maintain the water quality in a healthy state for a long time. The microbial system decomposes the organic matter in the water through its own metabolism. The microorganisms growing on the fiber ecological base can absorb the eutrophic components in the water body and enrich the eutrophic components such as nitrogen, phosphorus, sulfur and carbon. Through the action of different microorganisms, the transformation Become carbon dioxide, water and nitrogen, etc., thereby capturing the nutrients needed for the growth of blue-green algae, inhibiting the growth of blue-green algae, and gradually improving the water quality. the
