Abstract

The invention discloses a biological anchoring agent as well as a preparation method and application thereof. The biological anchoring agent is prepared from molasses, a chelating agent, a quorum sensing regulation factor, trace elements and water; wherein the concentration of the molasses is 100-200 g / L, the concentration of the chelating agent is 10-15 g / L, the concentration of the quorum sensing regulation factor is 0.002-0.3 g / L, and the concentration of the trace elements is 5-10 g / L. The anchoring agent can rapidly promote microorganisms to secrete a large amount of extracellular polymeric substances and attach the extracellular polymeric substances to a biological carrier, the microbial biomass and biological activity of a sewage treatment system are greatly improved, starting of the sewage treatment system can be rapidly completed, normal operation of the sewage treatment system can be achieved, and the impact resistance and environmental stress resistance of the sewage treatment system can be improved; the biological toxicity resistance, the temperature resistance and the salinity resistance of the sewage treatment system are improved, the sewage treatment system can be quickly recovered when being impacted, and the stable operation of the sewage treatment system is maintained.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a biological anchoring agent and its preparation method and application. Background technique [0002] With the development of social economy, the amount and types of wastewater are increasing day by day, and the impact on the environment is becoming more and more serious. Moreover, the national control is becoming more and more strict, and the requirements for enterprises and various sewage plants are getting higher and higher. Therefore, the start-up requirements for sewage treatment systems are getting higher and higher. [0003] The traditional sewage treatment system has a start-up cycle of several months or even half a year. During this period, the water quality is often not up to standard, which seriously affects the surrounding environment and the quality of drinking water, and poses a huge threat to people's health. Wastewater that does not meet the standards will cause...
