- Abstract:
- Treatment capacity of an industrial wastewater treatment plant in Wuxi is 6.0×104 m3/d. Base on the principle of moderate advance, the designed effluent quality needs to meet surface water quasi-Ⅳ standard (except TN ) in the upgrading and reconstruction project. However, the influent is characterized by a high proportion of industrial wastewater and complex composition. In order to ensure that the effluent quality meeting the discharge standard, shallow air flotation was employed as the pretreatment process, and biological aerated filter (BAF), deep bed denitrification filter and homogeneous catalytic ozonation technology were constructed to be the advanced treatment process based on the results of pilot experiments. After application of the project, the actual effluent quality stably met the design requirements, and it was flexible for managers to modify operating parameters according to the influent quality to reduce the operational cost.
