Abstract:
To study the removal performance of slow sand filter for di(2-ethylhexyl) phthalate (DEHP) in secondary effluent from wastewater treatment, a pilot scale slow sand filter with 0.4~0.6 mm granular diameter quartz sands as 800 mm depth filter bed was operated as an advanced wastewater treatment unit. Results showed that the turbidity, chemical oxygen demand and color in effluent of the slow sand filter were far below Water Quality Standard for Urban Miscellaneous Water Consumption: Urban Recycling Water (GB/T18920-2002).When DEHP in influent of slow sand filter was 6.1~62.8 μg/L, DEHP in effluent was declined to 1.7~7.3 μg/L.When a shock concentration of DEHP 282.8 μg/L in influent was applied to the slow sand filter, DEHP in the effluent was below 10 μg/L. The excellent performances of the slow sand filter for DEHP removal from wastewater were contributed by biofilm adsorption, filtration and biodegradation in the bed of the slow sand filter.
