How incredible was it for the Willow leaf floating duckweed cultivated by Chairman Qin to be able to reduce the seriously polluted sewage by more than 400 TD values in such a short time?
if he put more willow leaves in it, the sewage would be completely purified by tomorrow morning.
The researchers were also shocked.
this was because they knew how unbelievable it was. it could even be said that it was a little fantasy.
Soon, the special willow leaf duckweed in the other sewage also slowly rolled into a ball and turned black.
The first thing professor Liu did was to ask the researchers to do another test on the quality of the sewage.
The final result was just as shocking.
after each bucket of sewage was tested, the td value dropped by more than 400. none of them exceeded 1000.
Even modern technology for sewage treatment was not as effective as this. It would cost a lot of money to treat this level of pollution.
