Problems solved by technology

With the increasingly serious problem of water eutrophication, the sewage discharge standards of sewage treatment plants will gradually increase, but the existing biological denitrification technology has poor treatment effect and high operating costs, making it difficult to achieve the standard discharge of nitrogen-containing pollutants

Abstract

The invention discloses sludge treatment filler and a preparation method thereof. The filler is prepared from components in parts by mass as follows: 15-25 parts of ceramsite, 13-15 parts of talc powder, 6-8 parts of organic matter, 6-8 parts of humic acid, 15-25 parts of limestone, 6-10 parts of gypsum, 6-8 parts of basalt particles, 1-3 parts of a porous suspension, 10-12 parts of Mengmoli pumice, 10-12 parts of fly ash, 13-15 parts of activated sludge and 1-2 parts of an oxidizing agent. Electron and proton transfer is promoted by using a porous carrier with conductivity, and organic pollutants and nitrogen-containing pollutants in sewage can be synchronously and efficiently removed.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a filler for sewage treatment and a preparation method thereof. Background technique [0002] At present, the number of urban sewage treatment plants continues to increase, and the sewage treatment rate also continues to increase, but the problem of water eutrophication has not been well resolved, mainly due to the low removal rate of total nitrogen in the existing biological denitrification technology, A considerable part of ammoniacal nitrogen (NH4+-N) is only converted into nitrate nitrogen (NO3--N), but not fundamentally removed. Due to the problem of eutrophication, large-scale outbreaks of blue-green algae have occurred every year in Taihu Lake and Dianchi Lake in my country in recent years. With the increasing eutrophication of water bodies, the sewage discharge standards of sewage treatment plants will gradually increase. However, the existing biological denitri...
