Contact oxidation is used to deal with the paper effluent from an enterprise of Tieling in this paper. The practical operation indicates that this technology overcomes the shortcomings of the traditional activated sludge process and has the characteristics of high anti-impact ability, high load, ran stably, the water quality of effluent is high and so on. At the same time, its one-time investment and occupation area are small, and its operation management is convenient. The wastewater quality of Contact oxidation can achieve that: CODcr≤80mg/L; SS≤20mg/L; BOD5≤30mg/L. Every index of the effluent can accord with the pulp and paper industry standards.
