Biological carrier for purifying water body

Abstract

The invention belongs to the field of water body purification treatment and provides a biological carrier for purifying a water body. The biological carrier comprises a steel wire rope, lock latches, basalt fiber bundle group pieces, PVC end pieces and PVC short sleeves, wherein the components are in a relationship that the basalt fiber bundle group pieces are arranged on the anti-dropping PVC end pieces; adjacent basalt fiber bundle group pieces are partitioned by a plurality of PVC short sleeves; the PVC end pieces are arranged at the tail ends of the basalt fiber bundle group pieces; the central steel wire rope penetrates through the central holes of the components; two ends of the central steel wire rope are locked and fixed into rings by the lock latches. The basalt fiber wires on basalt fiber pieces stretch in an annular manner. The biological carrier for purifying the water body, which is provided by the invention, has the characteristics that the fiber wires are easy to stretch, not easy to drop off, long in service life, large in specific surface area, high in utilization efficiency and the like.

Description

technical field [0001] The invention belongs to the field of water body purification treatment, and in particular relates to a biological carrier for water body purification. Background technique [0002] The key to the water treatment biofilm method is to provide a suitable place for the growth and reproduction of a large number of microorganisms, so as to facilitate the adsorption and conversion of pollutants in sewage by microorganisms, and then achieve efficient sewage treatment effects. The addition of biological purification carrier can maintain higher biomass and richer biological phase in sewage. It can be seen that biological purification carrier is the foundation of sewage treatment biofilm technology. Therefore, many researchers at home and abroad have devoted themselves to the research and development of new biological carriers for a long time. [0003] With the further development of material science, a series of biological materials developed to meet the follo...

AI Technical Summary

Problems solved by technology

For example: coke, granular activated carbon, quartz sand and other inorganic biological carriers, although they have strong mechanical strength and good biocompatibility, but their specific gravity is large, the operation is complicated, and there is a problem that it is difficult to recycle.

However, organic composite bio-purification carriers such as PE, PVC and PP have poor hydrophilicity and bio-affinity (biocompatibility and bioactivity), resulting in surface wetting, mass transfer performance and microbial attachment and growth characteristics of biological fillers. Poor, there are deficiencies in the start-up speed of microbial film formation, the amount of film formation, the tightness of the film and filler, the activity of microbial cells and the utilization rate of oxygen.
