Problems solved by technology

It can be seen that many existing technologies only start from the perspective of reducing carbon source consumption or improving carbon source utilization, and most of them cannot get rid of the shackles of "carbon source". They all achieve the purpose of reducing the risk of exceeding the standard through system optimization and management. And it is impossible to eliminate the hidden danger of exceeding the standard

Abstract

The invention provides a denitrification biological filter. The denitrification biological filter comprises a water inlet pipe, a tank body and a water outlet pipe, the upper part of the tank body is connected with a water outlet pipe; the tank body is sequentially provided with a distributor, a denitrification biological filler layer and an interception medium layer from bottom to top; the filler of the denitrification biological filler layer contains aluminum, copper, zinc and sulfur. The denitrification biological filter has the advantages that the blockage probability is reduced, the denitrification rate is increased, the reaction retention time is shortened, the backwashing intensity is low, the time is short, and the risk that organic matters in effluent exceed the standard can be eliminated without adding an organic carbon source.

Description

technical field [0001] The invention belongs to the field of environmental science and engineering, and relates to a denitrification biological filter, in particular to a denitrification biological filter without organic carbon source in the sewage treatment industry. Background technique [0002] The increasing material and cultural needs of human beings have forced the rapid development of industry, resulting in an increase in the discharge of pollutants and the deterioration of the ecological environment of water bodies. In order to improve the quality of water environment, denitrification treatment of sewage is becoming a new focus of research by domestic and foreign experts and scholars. Nitrogen in sewage is one of the main factors causing water eutrophication. Biological denitrification is an effective method to remove nitrogen in sewage, but it needs sufficient carbon source. The traditional deep bed denitrification biofilter uses methanol, glucose, sodium acetate a...
