Gauze bio-packing apparatus

Abstract

The invention provides a retiform biological filling device and relates to a water root position cleaning treatment biological filling device. The retiform biological filling device comprises a filling grid (1), a combination filling unit (2), a rope (3), a float ball (4), a sleeve (5) and a dead lever (6); the combination filling unit (2) is fixedly connected with the grid crunode of the filling grid (1), the upper end of the filling grid (1) is connected with the float ball (4) by the rope (3), the two ends of the filling grid (1) is fixedly connected with the sleeve (5) by fixed boundary lines, when in use, the dead lever (6) is inserted in the sleeve (5), and fixation to the retiform biological filling is realized. The retiform biological filling of the invention has the advantages of simple structure, high specific surface area, convenient processing and transportation, not jamming, not caking, long service life, simple installation, convenient management and maintenance, strong ability of anti impulsion of water flow, and the like, which can be used in root position cleaning treatment of natural water such as riverway, lake and reservoir, and artificial water.

Description

technical field [0001] A netted biological packing device relates to a biological packing device for in-situ purification of water bodies. It specifically relates to a biological filler device used for in-situ purification treatment of natural water bodies and artificial water bodies, and belongs to the technical field of water treatment. Background technique [0002] In recent years, with the rapid development of social economy, the amount of pollutants discharged into water bodies has increased year by year, causing the natural water bodies such as rivers, lakes and reservoirs in our country to be polluted to varying degrees, and there is a tendency to intensify, seriously threatening people's lives and health. The pollution prevention and control of natural water bodies has become a major problem to be solved urgently. The biofilm contact oxidation method is one of the main processes for the restoration of polluted natural water bodies (rivers, lakes and reservoirs). It ...

AI Technical Summary

Problems solved by technology

The above-mentioned synthetic fillers are widely used in sewage treatment and have achieved good treatment effects. However, since these fillers are all developed for the application of sewage treatment plants, the geographical characteristics and characteristics of natural water bodies (such as rivers and lakes) are not considered. Hydrological characteristics, etc. Therefore, in the application of natural water purification, there are difficulties in installation and management, vulnerable to water impact damage, affecting water body functions (such as shipping, flood discharge) and not suitable for in-situ treatment, which greatly limits its use in polluted natural water. Practical application in water purification treatment
