Problems solved by technology

[0004] Biological denitrification efficiency is limited by temperature and nitrogen concentration. Generally, strains have a narrow adaptability to nitrogen concentration, and their denitrification ability decreases at low temperature (<10°C), so they are not suitable for denitrification of low-temperature water source water.

Abstract

The invention discloses low-temperature denitrification pseudomonas fluorescens and relates to pseudomonas fluorescens. The low-temperature denitrification pseudomonas fluorescens are pseudomonas fluorescens WSW-1001 and are collected in China General Microbiological Culture Collection Center (CGMCC), the collection number is CGMCC No.7476, the collection date is April 15th, 2013, and the collection address is No.3, No.1 Courtyard, Beichen Road, Chaoyang District, Beijing. The low-temperature denitrification pseudomonas fluorescens are heterotrophic nitrification aerobic denitrifiers, can be used for degrading NH4+-N, NO--N and NO--N (0.25 mg / L-1314.1 mg / L) with a wide concentration range, can be applied to low-nitrogen pollution source water denitrification, medium- and high-concentration wastewater denitrification and eutrophic water body treatment, and have an important meaning on low-nitrogen pollution source water denitrification, water eutrophication control and biological environment modification.

Description

technical field [0001] The invention relates to a strain of Pseudomonas fluorescens. Background technique [0002] With the rapid development of society and economy, nitrogen pollution in my country's water environment is becoming more and more serious. Domestic sewage, industrial wastewater, aquaculture wastewater and farmland nitrogen fertilizer are the main sources of nitrogen pollution in the water environment. Water nitrogen pollution not only causes serious environmental pollution and economic losses, but even threatens human health and ecological security. Microbial nitrogen removal is considered to be the most economical, effective and promising water nitrogen removal technology due to its advantages of high efficiency, low cost, and no secondary pollution. [0003] Nitrogen in polluted water mainly includes NH 4 + -N, NO 3 - -N and NO 2 - -N inorganic nitrogen and organic nitrogen. Traditional biological denitrification includes ammonification, nitrificatio...
