Abstract

The invention discloses Chryseobacterium sp. for removing phosphorus in sewage at low temperature and a separation culture method. The Chryseobacterium sp. deep yellow polyphosphorus CGMCC No.5282 for removing the phosphorus in the sewage at low temperature has the ability of removing the phosphorus in the sewage at low temperature under aerobic conditions. The experimental result shows that: in spite of obvious inhibition of a low-temperature environment, the Chryseobacterium sp. deep yellow polyphosphorus CGMCC No.5282 for removing the phosphorus in the sewage at low temperature has a remarkable effect of strengthening the removal of the phosphorus at low temperature, especially at the temperature of between 8 and 12 DEG C, and the removal rate of the phosphorus is improved by 10 percent; and the effluent standard is superior to the first-grade A effluent standard (water temperature is less than or equal to 12 DEG C, and the control index of the first-grade A standard is 0.5mg / L).

Description

technical field

[0001] The invention belongs to the field of sewage treatment, and relates to a Chryseobacterium strain capable of removing phosphorus in sewage at low temperature and an isolation and cultivation method. Background technique

[0002] The reason why low temperature has a significant impact on biological treatment capacity is that the decrease in temperature affects the growth and metabolism of microorganisms. Although phosphorus-accumulating bacteria are low-temperature psychrotrophic bacteria, the phosphorus-releasing and phosphorus-absorbing rates of phosphorus-accumulating bacteria are also affected during the temperature drop process, resulting in a decline in the quality of effluent from sewage treatment plants in winter. Therefore, there is an urgent need for a bacterial strain that can strengthen the removal of phosphorus in sewage under low temperature conditions. Contents of the invention

[0003] The purpose of the present invention is to overcom...
