our laboratory has done an experimental test. The water we took is serious waste water discharged from the factory, and the TD value is more than 1000.
after a night of purification, our willow leaf duckweed directly reduced the TZ value of the wastewater to below 10. All the harmful substances in the sewage were absorbed by the Willow leaf duckweed. That's the specific situation.
when minister lu heard this, he felt that it must be very impressive for a 1000-plus td value to be reduced to less than 10.
however, the person in charge of the water quality control was shocked and couldn't help but exclaim, " "How could such a thing happen?"
The leader looked at the person in charge in surprise.
Seeing this, Minister Lu also said into the phone, " "boss qin, i won't bother you anymore."
