Research on improvement of DAT-IAT municipal wastewater treatment process based on eco-safety
基于生态安全的DAT-IAT城市污水处理工艺改进研究

Optimum conditions of regular indicators removal and ecotoxicology indicators reduction of municipal wastewater treated by DAT-IAT process and A/DAT-IAT process were studied by orthogonal experiments.Results showed that in the same orthogonal experimental process,the effluents COD under the optimum COD removal conditions were better than that under the optimum ecotoxicity reduction conditions,but the effluents ecotoxicity of the former were higher than that of the latter.Because of hydrolysis-acidification,...
