Problems solved by technology

Biofilm fillers can be roughly divided into two types: organic fillers and inorganic fillers. The former has poor biocompatibility, while the latter has a small specific surface area and is easy to clog. Existing fillers cannot simultaneously meet the requirements of good biocompatibility, large specific surface area and not easy to clog. Require

Abstract

The invention discloses a water treatment filler and a preparation method thereof, comprising an embedding carrier and an embedding content. The embedding carrier includes: 20-30 parts of montmorillonite, 90-110 parts of waste incineration fly ash, and 15-15 parts of carbon fiber bundles 25 parts, 3‑5 parts of gelatin, 5‑8 parts of modified chitosan, 20‑30 parts of agricultural and forestry wastes, embedding contents include: 5‑8 parts of vitamin E, 7‑9 parts of lysine, 6‑ 3-5 parts of benzyl adenine, 15-18 parts of iron, 15-17 parts of zinc, 5-8 parts of manganese, 6-7 parts of cobalt, 20-30 parts of glucose, the fermentation product is obtained by anaerobic fermentation of agricultural and forestry waste , adding the raw materials to the fermentation product and roasting to obtain the carrier, and coating the embedding carrier and the embedding content to obtain the water treatment filler. The filler of the present invention can simultaneously meet the requirements of good biocompatibility, large specific surface area and not easy to clog.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a water treatment filler and a preparation method thereof. Background technique [0002] With the increasing attention and great attention to the nitrogen pollution of water bodies at home and abroad, the effluent standards of sewage treatment plants are becoming more and more stringent. Sewage treatment plants in my country generally require strict implementation of the "Pollutant Discharge Standards for Urban Sewage Treatment Plants" (GB18918-2002) Class A Standard. However, the denitrification effect of the existing technology is difficult to meet the requirements of raising the total nitrogen (TN), and the existing technology must be upgraded. [0003] Water body denitrification technology includes physical chemical method and biological method. Although the physical and chemical method is simple, it is easy to cause secondary pollution. At present, most sewage tre...
