Problems solved by technology
Biological denitrification technology can be divided into heterotrophic denitrification technology and autotrophic denitrification technology. Traditional water body denitrification technology usually only adopts one of heterotrophic denitrification technology and autotrophic denitrification technology. However, a single heterotrophic denitrification technology When denitrification technology or autotrophic denitrification technology is applied to water body denitrification treatment, there is a problem that the denitrification treatment effect of water body is unstable, and it cannot meet the actual needs of water body denitrification denitrification

Abstract
The invention discloses a filler, a preparation method and an application method of the filler and a water treatment device. The filler comprises polycaprolactone, elemental sulfur and siderite. When a water body to be treated flows through the filler with heterotrophic microorganisms and autotrophic microorganisms attached to the surface, the heterotrophic microorganisms can utilize polycaprolactone in the filler as a carbon source to carry out heterotrophic denitrification treatment on the water body, so nitrate nitrogen in the water body is removed and alkalinity is generated at the same time; and the autotrophic microorganisms can utilize elemental sulfur in the filler as an electron donor, the water body is subjected to autotrophic denitrification treatment in combination with alkalinity generated by heterotrophic denitrification of heterotrophic microorganisms in polycaprolactone, so nitrate nitrogen in the water body is further removed; and therefore, the filler realizes organic combination of heterotrophic denitrification treatment and autotrophic denitrification treatment of the heterotrophic microorganisms and the autotrophic microorganisms on the water body through coupling of the polycaprolactone and the elemental sulfur, and the denitrification efficiency of the water body is effectively improved.
Description
technical field [0001] The invention relates to the technical field of water treatment, in particular to a filler, a preparation and application method of the filler and a water treatment device. Background technique [0002] Biological denitrification technology refers to the use of autotrophic or heterotrophic microorganisms for denitrification to convert nitrate nitrogen in the water body into nitrogen gas, thereby achieving the complete removal of nitrate nitrogen in the water body. Biological denitrification technology can be divided into heterotrophic denitrification technology and autotrophic denitrification technology. Traditional water body denitrification technology usually only adopts one of heterotrophic denitrification technology and autotrophic denitrification technology. However, a single heterotrophic denitrification technology When denitrification technology or autotrophic denitrification technology is applied to denitrification treatment of water body, ther...
