Embodiment Construction

[0024] figure 1 The middle mark 1 is a fold, and 2 is a ditch.

[0025] Such as figure 1 The shown embodiment of a spiral strip packing includes a bent strip-shaped packing body, the packing body includes continuous "S"-shaped folds, and each fold 1 of the folds encloses a semi-closed space for fluid to enter. The semi-enclosed space is trumpet-shaped or funnel-shaped, and the folded surface forms a microbial attachment surface.

[0026] In this embodiment, the "S"-shaped folds formed on the filler body increase the specific surface area and the attachment area of ​​microorganisms, making it easier for microorganisms to attach to the surface. When water or air flows through the pleats, it swirls in the semi-enclosed space surrounded by the pleats 1 to form a vortex, and the microorganisms are fully mixed with gas and water, which effectively improves the utilization rate of water and gas, and improves the treatment efficiency. At the same time, when the curved strip-shaped ...

Abstract

The invention relates to a spiral strip filler which comprises a bent strip filler body, wherein the filler body comprises a plurality of continuous-S-shaped wrinkle, each fold of the wrinkle forms a semiclosed space into which a fluid can flow, and a microbial attachment surface is formed on the surface of each wrinkle. The S-shaped wrinkles formed on the filler body increase the specific area and microbial attachment area; and water or gas flowing across the folds rotates in the semiclosed space formed by each fold to form a swirl and is thoroughly mixed, thereby effectively enhancing the utilization ratio of water and gas, and enhancing the treatment efficiency. Meanwhile, when the bent strip filler body is filled in bulk, the bends and wrinkles are superimposed to form a steady integral body, so that rolls can not be easily formed under quick or massive water impact, thereby effectively protecting the biofilm attached to the filler surface, and ensuring the stability of the biofilm. The spiral strip filler is applicable to environment treatment.

Description

technical field [0001] The invention relates to a biological filler, in particular to a spiral strip filler. Background technique [0002] my country is one of the most water-poor countries in the world, with a per capita water volume of only a quarter of the world's. In recent years, the quality of groundwater in some cities in my country is not up to standard, and the pollution of water source water quality is showing a worsening trend. In 2011, the Ministry of Environmental Protection conducted a survey on the environmental conditions of centralized drinking water sources in cities above the prefecture level. After random inspection of the terminal water of the type water supply pipe network, it was found that the pass rate was only 82.6% based on 7 indicators including turbidity, chroma, and total coliforms. Medical epidemiology has found that 70% to 80% of human diseases at home and abroad are closely related to water pollution. the [0003] Currently used sewage tr...
