Embodiment 1
[0020] 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 housefly eggs on the surface of the culture material, and the egg density is: 0.2g housefly eggs / kg culture material. The culture temperature was set at 30°C, and the housefly 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 4th day, put a larger container outside the culture container, and sprinkle dry rice bran powder in it to facilitate the collection of mature housefly maggots. After 4-5 days, the housefly larvae have reached the mature state, and they climbed out of the co...
Embodiment 2
[0024] 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 housefly eggs on the surface of the culture material, and the egg density is: 0.6g housefly eggs / kg culture material. The culture temperature was set at 25°C, the housefly 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 4th day, put a larger container outside the culture container, and sprinkle dry rice bran powder in it to facilitate the collection of mature housefly maggots. After 4~5 days, the housefly larvae have reached the mature state, and they climbed out of the co...
Embodiment 3
[0028] 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 housefly eggs on the surface of the culture material, and the egg density is: 0.8g housefly eggs / kg culture material. At room temperature, the housefly eggs hatched into larvae on the 2nd day and began to decompose and transform the compost. The culture temperature is set at 20-25°C, and the water should be properly supplemented during the culture process to prevent the temperature from rising too high. On the 4th day, put a larger container outside the culture container, and sprinkle dry rice bran powder in it to facilitate the collection of mature housefly maggots. After 4~5 days, when the housefly larvae have reache...
