Operations Analysis and Process Discussion on the Treatment of Wastewater from Papermaking Reconstituted Tobacco
The process of"physical slag removal+A2O biological treatment+chemical advanced treatment"was adopted to treat wastewater in the tobacco leaf regenerated plant,the operation analysis was carried out for the treatment capacity of each process,the removal efficiency of each pollutant index and the transformation of nitrogen-containing substances.The operation data showed that the pH value of the anaerobic influent was 7.5～7.8,and the average concentration of suspended solids(SS)was 1 058 mg/L,both of which were on the high side,and the anaerobic sludge loss was serious,the average removal rate of total nitrogen in A2O process was 47.7％,which needed further improvement and optimization.In view of the existing problems,this paper probed into the causes of the problems in the light of the characteristics of the water quality and the operation parameters of the enterprise process for tobacco leaf regenerated by paper-making,and putted forward some com-ments and suggestions for improving the process.It provided reference for the construction and improvement of wastewater treatment process.
