14 Industrial Wastewater Treatment Principals and Ideas

The cyanide-containing wastewater mainly comes from the departments of electroplating, gas, coking, metallurgy, metal processing, chemical fiber, plastics, pesticides, and chemicals. Cyanide-containing wastewater is a kind of toxic industrial wastewater. It is unstable in water and easy to decompose.

A definition of pH is an expression of the intensity of the basic or acidic condition of wastewater. Mathematically, pH is the logarithm (base 10) of the reciprocal of the hydrogen ion activity. The pH is expressed numerically ranging above 0 thru 14. A pH or 7.0 is neutral and pH below 7.0 is acidic and pH above 7.0 is basic or alkaline.

A pH less than 7 is ,acidic, and a pH greater than 7 is ,alkaline,. The pH scale is logarithmic so for every one unit of change in pH there is a tenfold change in ion concentration. This means a solution with a pH of 3 is 10 times more ,acidic, than a solution with a pH of 4 and 100 times more ,acidic, …
