Embodiment 1
[0021] After extracting human feces from the septic tank, filter out the sundries through a mesh screen with a hole size of 2 cm, add appropriate amount of auxiliary materials (see Table 1), stir evenly, and prepare compost. Pour the culture material into the corresponding container, the height of the culture material is 4cm, and insert an appropriate amount of black soldier fly eggs on the surface of the culture material, and the egg density is: 0.2g black soldier fly eggs / kg culture material. The culture temperature was set at 30°C, and the black soldier fly eggs hatched into larvae on the 2nd day, and began to decompose and transform the compost. Properly replenish water during the cultivation process to prevent excessive temperature rise. On the 18th day, put a larger container outside the culture container, and sprinkle dry rice bran powder in it to facilitate the collection of mature black soldier fly maggots. After 20-25 days, the black soldier fly larvae have reached ...
Embodiment 2
[0026] After extracting the human feces from the septic tank, filter out the sundries through a mesh screen with a hole size of 6 cm, add appropriate amount of auxiliary materials (see Table 2), stir evenly, and prepare compost. Pour the culture material into the corresponding container, the height of the culture material is 6cm, and insert an appropriate amount of black soldier fly eggs on the surface of the culture material, and the egg density is: 0.6g black soldier fly eggs / kg culture material. The culture temperature was 25°C, and the black soldier fly eggs hatched into larvae on the 2nd day, and began to decompose and transform the compost. Properly replenish water during the cultivation process to prevent excessive temperature rise. On the 20th day, a larger container was placed outside the culture container, and dry rice bran powder was sprinkled into it to facilitate the collection of mature black soldier fly maggots. After 25-30 days, the black soldier fly larvae ha...
Embodiment 3
[0030] After extracting human feces from the septic tank, filter out the sundries through a mesh screen with a hole size of 8 cm, add appropriate amount of auxiliary materials (see Table 3), stir evenly, and prepare compost. Pour the culture material into the corresponding container, the height of the culture material is 8cm, and insert an appropriate amount of black soldier fly eggs on the surface of the culture material, and the egg density is: 0.8g black soldier fly eggs / kg culture material. The culture temperature was set at 27°C, and the black soldier fly eggs hatched into larvae on the 2nd day, and began to decompose and transform the compost. Properly replenish water during the cultivation process to prevent excessive temperature rise. On the 18th day, put a larger container outside the culture container, and sprinkle dry rice bran powder in it to facilitate the collection of mature black soldier fly maggots. After 20 to 30 days, when the black soldier fly larvae have ...
