1.
A thermal power plant in Ningbo is a thermal power plant using coal as fuel.
2.
The sludge is incinerated at a high temperature in the furnace, and the fly ash basically does not contain organic pesticides, organic compounds, alkyl mercury and other substances.
Table 10-16 Test results of mass concentration, acute toxicity and corrosiveness of toxic substances
Table 10-17 Test results of leaching toxicity
3.
After a small amount of dyeing blended power plant sludge and sewage sludge, fly ash toxic substances (dioxins), acute toxicity (lethal dose oral toxicity the LD 50 , the LD Dermal toxicity lethal dose 50 , and the half lethal dose inhalation toxicity LD 50 ), leaching toxicity (inorganic elements and compounds) and corrosiveness (pH), etc.
Negative pH
1.
The sample to be identified is a dark green liquid
2.
The pH was measured directly, and it was found to be negative, which was less than the resolution of the instrument 0.
3.
The pH is the negative value of the common logarithm of the mass concentration of hydrogen ions, and the pH changes with the mass concentration of hydrogen ions
