Abstract

The invention discloses a bioactive carbon source for sewage treatment and a preparation method thereof. The bioactive carbon source comprise the following raw materials in parts by weight: 30 to 35 parts of polyol, 10 to 20 parts of chitin, 0.5 to 1.5 parts of vitamins, 3 to 6 parts of glucose, 20 to 22 parts of crude glycerol, 2 to 5 parts of strains and 20 to 25.5 parts of deionized water, wherein the strains are any one or a combination selected from the group consisting of bacteria, actinomycetes, saccharomycetes and molds. The invention relates to the technical field of sewage treatment.According to the bioactive carbon source for sewage treatment and the preparation method thereof, the polyol is used as a substrate; the chitin, the vitamins, the glucose, the crude glycerol and thestrains are used as raw materials to form a carbon source; the bioactive carbon source prepared by using the preparation method provided by the invention can reach a COD equivalent of 200000 mg / L or above and a pH value of 5 to 7; denitrification nitrogen removal is effectively promoted; biological phosphorus removal is reinforced; the input cost is low; the adding amount is small; the operation cost is greatly reduced; the explosive and inflammable characteristics of methyl alcohol and ethyl alcohol serving as carbon sources are avoided; potential safety hazards are eliminated; and the purpose of safe use is achieved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a biologically active carbon source for sewage treatment and a preparation method thereof. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or for reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical care, catering, etc., and it is also increasingly entering the daily life of ordinary people. At present, nitrogen pollution in water bodies in our country The problem is already very serious. According to the survey, sewage plants can easily convert ammonia nitrogen into nitrate nitrogen, and ammonia nitrogen can easily meet the discharge standards. However, due to the lack of carbon sources and low C / N values, the denitrification proce...
