Abstract

The invention belongs to the technical field of sewage treatment and in particular relates to a biological accelerant which consists of the following components in parts by mass: 1-9 parts of vitaminH, 0.5-3.5 parts of 6-benzyl purine, 2-15 parts of aspartic acid, 0-6 parts of glycine, 0-8 parts of glutamic acid, 0-4 parts of flavin adenine dinucleotide, 0-4 parts of humic acid, 0-3 parts of anthraquinone-2-sodium sulfonate and 0-3.5 parts of 1,2-naphthoquinone-4-sulfonic acid, wherein the mass parts of the six components such as glycine, glutamic acid, flavin adenine dinucleotide, humic acid, anthraquinone-2-sodium sulfonate and 1,2-naphthoquinone-4-sulfonic acid are not simultaneously 0. Compared with the prior art, the biological accelerant provided by the invention is nontoxic and isfree of secondary pollution on the environment, and in addition, the substances are all easy in microorganism utilization and are beneficial to rapid activity recovery of denitrifying bacteria after inhibition. Therefore, the biological accelerant provided by the invention can be adopted for rapid recovery of nitrifying bacteria after inhibition with heavy metals in sewage treatment.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a bioaccelerator and its application. Background technique [0002] Denitrification is an important part of the biological denitrification process. Under the leadership of denitrifying bacteria, nitrogen oxides are used as electron acceptors, organic or inorganic substances are used as electron donors and energy sources, and NO 3 - in turn converted to NO 2 - -N, NO, N 2 O and N 2 , and eventually released into the atmosphere. Denitrification can not only effectively reduce the nitrogen content in groundwater, drinking water, and wastewater, but also plays an important role in the global nitrogen cycle. [0003] In recent years, with the rapid development of industry, electroplating, metallurgy, chemical industry and other industries have produced a large amount of wastewater containing hexavalent chromium. Some urban sewage treatment plants will accept...
