Problems solved by technology

[0005] However, the domestic sewage discharged in daily life and the printing and dyeing wastewater discharged from the printing and dyeing industry generally contain more total nitrogen content, and the presence of nitrate nitrogen in the anaerobic environment of the phosphorus accumulating bacteria agent will consume organic substrates and inhibit PAO. The release of phosphorus, thus affecting the absorption of phosphorus by phosphorus accumulating bacteria under aerobic conditions
Moreover, in an anaerobic environment, the presence of nitrate nitrogen will be used by Aeromonas as an electron acceptor for denitrification, thereby affecting its use of fermentation intermediates as electron acceptors for fermentation and acid production, thereby inhibiting the phosphorus release of PAO and phosphorus uptake ability and PHB synthesis ability, resulting in reduced treatment effect on sewage

Abstract

The invention relates to a phosphorus-accumulating bacterial agent and a sludge treatment technology using the bacterial agent, and relates to the technical field of activated sludge, which comprises the following components in weight percent: 16-20% Acinetobacter, Pseudomonas Bacteria 12‑16%, Aeromonas 12‑16%, Nutrient 20‑24%, Bioaugmentation carrier 16‑20%, Acid-base slow-release agent 3‑5%, First auxiliary agent 3‑5 %. By adding the first auxiliary agent and the bio-synergistic carrier, a synergistic effect occurs between the two to reduce the content of nitrate nitrogen in and around the granulated sludge, thereby improving the efficiency and effect of sewage treatment.

Description

technical field [0001] The invention relates to the technical field of activated sludge, in particular to a phosphorus-accumulating bacterial agent and a sludge treatment technology using the bacterial agent. Background technique [0002] Along with the rapid development of my country's chemical industry, the phosphorus chemical industry in my country has developed rapidly in the past two decades and has achieved encouraging results. However, with the development of phosphorus chemical industry, the environmental pollution is becoming more and more serious. At this stage, phosphorus removal methods include chemical precipitation, ion exchange, adsorption, membrane separation and biological methods. Compared with the traditional physical and chemical methods, the biological method has the advantages of less economic cost, less impact on the environment, fewer remaining problems, minimizing the concentration of pollutants, and shorter repair time. [0003] There is a kind of...
