Novel eutrophic water purification medium, corresponding ecological floating bed as well as production method and water purification method of eutrophic water purification medium

Abstract

The invention relates to a novel eutrophic water purification medium, a production method and a corresponding ecological floating bed, and aims to solve the problem that eutrophic elements such as nitrogen, phosphorus and the like cannot be really removed during treatment of eutrophic water in the prior art. The eutrophic water purification medium comprises a hanger and two elastic spiral ropes, the tops of the two elastic spiral ropes are bent to form buckles and suspended on the hanger through the buckles, the spiral axes of the two elastic spiral ropes coincide and are symmetrical relative to the vertical plane of the hanger penetrating through the spiral axes, and flexible hollow fiber is uniformly and densely distributed on the elastic spiral ropes. The invention further relates to a corresponding novel medium production method and the ecological floating bed. Microorganisms are used for concentrating eutrophic elements such as nitrogen, phosphorus and the like and are converted into biological fertilizers which are rich in nitrogen and phosphorus, and the novel eutrophic water purification medium is applicable to eutrophication treatment of various waters.

Description

technical field [0001] The invention relates to a new medium for purifying eutrophic water body, a corresponding ecological floating bed, a production method thereof and a method for purifying water body. Background technique [0002] The ammonia and phosphorus-rich sewage discharged from agricultural non-point sources, industrial point sources and domestic sources has seriously polluted the surface water environment in my country. The number of eutrophic waters is increasing day by day, and many rivers, lakes, rivers and ponds have been seriously damaged. The compound ecological floating bed is an artificial medium unit added to the traditional floating bed, which overcomes the shortcomings of the single ecosystem of the traditional plant floating bed. [0003] The artificial medium is one of the important components in the construction of the compound ecological floating bed. The choice of artificial medium plays a key role in the water purification effect of the compound ...

AI Technical Summary

Problems solved by technology

The inorganic type mainly includes zeolite, sand, ceramsite, slag, montmorillonite, etc., but its density is high, it is difficult to grow in suspension, and the power consumption required for backwashing is also large, which limits its application range; the organic type mainly includes PVC, PE, etc. , PS, PP, various resins, plastics, fibers, and gelatin, etc., are suitable for suspension growth and are the main media used in the construction of ecological floating beds, but there are deficiencies in the amount of microbial film formation, and they are generally difficult to handle after use. , easy to cause secondary pollution to the environment and other problems
