Embodiment 1
[0022] Precipitate the aquatic product processing wastewater, remove the precipitation, and filter the supernatant fluid twice at a speed of 0.8m / s and apply 15mJ / cm 2 Ultraviolet light, add microbial starter (China Common Microbial Culture Collection and Management Center) Lactococcus lactis 0.3kg / L, Alcaligenes 0.2kg / L fermented for 2.5 days, put in Porphyridium seeds, cultivate for 3.5 days, and measure the growth rate OD 604nm (Spectrophotometer, 723 manual, Shanghai Binglin Electronic Technology Co., Ltd.), the results are shown in Table 1. During the cultivation period, the 30-minute music "Be with you through the long years" is played once.
Embodiment 2
[0024] Precipitate the aquatic product processing wastewater, remove the precipitation, and filter the supernatant fluidly at a speed of 1.7m / s for 3 times and apply 22.5mJ / cm 2 Under ultraviolet light, add 0.55kg / L of microbial starter Lactococcus lactis, 0.4kg / L of alkali-producing bacteria, ferment for 3.25d, put in Porphyridium seeds, cultivate for 4.5d, and measure its growth rate, namely OD 604nm The results are shown in Table 1. During the cultivation period, the 40-minute music "Imprint of Rain" was played twice.
Embodiment 3
[0026] Precipitate the aquatic product processing wastewater, remove the precipitation, and filter the supernatant 4 times at a speed of 2.6m / s and apply 30mJ / cm 2 UV light, add 0.8kg / L of microbial starter Lactococcus lactis, 0.6kg / L of alkali-producing bacteria, ferment for 4 days, put in Porphyridium seeds, cultivate for 5.5 days, and measure the growth rate (OD) 604nm , The results are shown in Table 1. During the cultivation period, the 50-minute music "The Meaning of Travel" was played three times during the day.
[0027] Table 1 Porphyridium growth rate
[0028] Sample
[0029] It can be seen from Table 1 that the cell density of Porphyridium spp. cultivated by the method provided by the present invention for accelerating the growth of Porphyridium spp. on the 3.5th day of cultivation reached 1.75 and entered the stable period of growth. It can be seen that the use of aquatic products provided by the present invention The method of processing wastewater to accelerate the ...
