Abstract:
This article explores treatment method of waste fountain solution from sheet-fed offset printing. First calcium chlorate is used to have a oxidation treatment for the waste water, then it is dealt with composite coagulants polyaluminium chloride (PAC) and cation polyacrylamide (CPAM) under different pH value. The results show that quality of the waste fountain solution could reach the national second-grade standard of sewage comprehensive discharge through the above treatment (GB 8978--1996) when treating with 0.7 g/L calcium hypochlorite and then sinking with PAC 4.0 g/L, CPAM 75.0 mg/L under the pH value of 8.0 for about 10 minutes. With the optimum treatment conditions removal rates of COD, ammonia nitrogen, phosphate and hexavalent chromium are above 90%, 94%, near to 98% and above 99% respectively.
