Abstract
In order to improve the effluent quality, the advanced treatment process mainly including the combination technology of highly efficient clarification tank and rotary filter was used for Chuanhu Wastewater Treatment Plant in Changchun city. This paper introduces the advanced wastewater treatment process, design parameters of main structures and corresponding equipment. The actual operation results show that advanced treatment process can achieve good effluent quality in spite of high contaminant concentration and big fluctuation of water quality of raw water.
