Design Example and Discussion of Industrial Sewage Treatment Plant in a Northern Building Materials and Chemical Industry Park
The recent design scale of an industrial sewage treatment plant in a northern building materials and chemical park is 2 000 m3/d,and the long-term design scale is 4 000 m3/d.Reasonable selection of sewage treatment process,using pretreatment(grid,lifting+sand+homogenization regulation,accident regulation+lime softening facilities)+filter+self-cleaning filter+UF device+RO device,sludge treatment using sludge treatment using sludge concentra-tion,conditioning+plate frame press filtration dehydration.The treated effluent meets the Level-A Standard of Pollut-ant Discharge Standard of Urban Sewage Treatment Plant,Water Quality of Urban Miscellaneous Water for Municipal Sewage Recycling and Industrial Water Quality of Urban Sewage Recycling,which can provide reference for the design of industrial sewage treatment plants in other similar building materials and chemical parks in China.
