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, and comprises inner side walls and outer side walls opposite to the inner side walls, wherein the inner side walls of the filler define a first overflowing space through enclosure, and second overflowing space is arranged outside the outer side walls ofthe filler. When a water body flows through the first overflowing space and air flows through the second overflowing space, the inner side walls of the filler can allow a biological membrane to growin an attached mode; and the air flowing through the second overflowing space can enter the filler through the outer side walls of the filler for dissolving and diffusion, then is diffused to the inner side walls of the filler, then is desorbed from the inner side walls of the filler and enters the first overflowing space to provide oxygen required by growth and metabolism of the biological membrane, so the biological membrane biodegrades oxygen-consuming pollutants in the water body flowing through the first overflowing space. The filler provided by the invention has the advantages of energyconsumption saving, small occupied area and high biochemical treatment efficiency.

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...
