Filler, water treatment device and water treatment method

Abstract

The invention discloses a filler, a water treatment device and a water treatment method. The filler has oxygen permeability and liquid resistance; the inner side wall of the filler is enclosed to forma first overflowing space, and a second overflowing space is arranged outside the outer side wall of the filler; the inner side wall of the filler can allow a biological membrane to grow in an attached mode; oxygen molecules in air flowing through the second overflowing space can enter the filler through the outer side wall of the filler for dissolving and diffusion, then are diffused to the inner side wall of the filler, are desorbed from the inner side wall of the filler and provide oxygen needed by growth and metabolism of the biological membrane, so the biological membrane is used for biodegrading oxygen-consuming pollutants in a water body flowing through the first overflowing space; and the first overflowing space extends in the axial direction of the filler, and the minimum size ofthe first overflowing space in a direction perpendicular to the axial direction of the filler is smaller than a first preset numerical value, so water entering the first overflowing space of the filler can flow in the axial direction of the filler.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a filler, a water treatment device and a water treatment method. Background technique [0002] At present, the most typical water treatment process for oxidizing oxygen-consuming pollutants such as ammonia nitrogen and organic matter in water bodies is the application of biofilm methods. The equipment used in the existing biofilm methods mainly includes contact oxidation, biological turntables, and biofilters. However, the above-mentioned technologies generally have problems such as large area occupation and low biochemical treatment efficiency, which are difficult to meet the actual needs of current water biochemical treatment. Contents of the invention [0003] Based on this, it is necessary to provide a filler, a water treatment device and a water treatment method with a small footprint and high biochemical treatment efficiency. [0004] A filler, the filler has ox...
