NOVELTY - Chryseobacterium (CGMCC 5282) is used for removing phosphorus in sewage at low temperature.    USE - Use of Chryseobacterium for removing phosphorus in sewage at low temperature (claimed).    ADVANTAGE - The Chryseobacterium removes phosphorus in sewage at 8-12 degrees C and at phosphorus removal rate increased by 10%, thus providing water that is better than level A (where water temperature is not greater than 12 and control index of first level A standard is 0.5 mg/l).    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for separation culture of Chryseobacterium by putting phosphorus rich culture liquid into small styrene butadiene rubber reactor; inoculating phosphorus-rich culture liquid at 8-12 degrees C with sewage treatment plant sludge; continuously culturing for 20 days; moving every 6 hours (i.e. anaerobic stirring for 2.5 hours, aerobic stirring for 2.5, standing for 0.5 hours, and discharging supernatant fluid and adding new phosphorus-rich culture liquid for 0.5 hours), such that during operation sludge concentration is 3000 mg/l; adding 10 ml sludge with 90 ml distilled water in 250 ml conical flask of 20-30 sterilizing glass; oscillating for 10-30 minutes to make cell sufficiently released to clear liquid; standing for 20-40 minutes; adding 1 ml clear liquid with 9 ml sterile distilled water to test tube to obtain bacterial suspension of 102; diluting into 108; selecting gradient of bacterial suspension at 105-108; taking 1 ml rich phosphorus solid culture medium for solution to make 3 parallel sample; culturing at 10 degrees C under oxygen for 2-3 weeks wet condition; selecting bacterial colony or different single bacterial colony from phosphorus rich solid culture medium flat; marking rich phosphorus solid culture medium flat to mark separation and recycling plate for 3-4 times so that bacterial colony on flat plate is the same as microscope shape, in which single and similar size is single strain consisting of deep yellow phosphorus; and removing low temperature sewage phosphorus via Chryseobacterium.
