It can not form, implement failure.
Experimental contrast analysis two:
For the technical essential for more intuitively reflecting this patent, the above 6-9 experimental example is compared and analyzed, is had as follows
Conclusion (data such as following table):
1, bacterium, fecal coliform can be killed effectively in 400 DEG C of stop 10S, can make induced worm egg death rate by material
Reach 100%.
2, material, can be effectively by killing bacteria in 400 DEG C of stop 5S, and fecal coliform can detect, and can make roundworm
Egg mortality reaches 99%, illustrates that material is inadequate in the residence time of high-temperature region.
3, material is more than 10S in 400 DEG C of residence times,, can although bacterium, fecal coliform can be killed when reaching 20S
So that induced worm egg death rate reaches 100%, but the organic matter of material will lose, and the calorific value of final products also reduces, and illustrates material
Residence time in high-temperature region is too long, and organic matter is caused to lose.
4, material is in 200 DEG C of stop 10S, and because temperature does not reach requirement, excrement colibacillus group increases, induced worm egg death rate drop
It is low, illustrate that temperature is inadequate.
