Abstract
The invention discloses an oily wastewater and sludge treatment device which comprises a grating well, a regulation precipitation inclined plate oil separation tank and a sludge drying bed, wherein the grating well is communicated with the regulation precipitation inclined plate oil separation tank through a water inlet formed in a front tank wall of the regulation precipitation inclined plate oil separation tank; a water inlet end mud bucket and a water outlet end mud bucket are arranged at the two ends of the bottom of the regulation precipitation inclined plate oil separation tank; an oil separation inclined plate group and a baffle are arranged at the water outlet end mud bucket; the sludge drying bed is sleeved in the regulation precipitation inclined plate oil separation tank; the two side wall surfaces of the sludge drying bed are integrated with those of the regulation precipitation inclined plate oil separation tank; and a bottom plate of the sludge drying bed is higher than the working water level of the regulation precipitation inclined plate oil separation tank. According to the oily wastewater and sludge treatment device, a grating treatment unit, a regulation precipitation treatment unit and an inclined plate oil separation treatment unit are integrated on a plane according to a flow sequence, and the sludge drying bed is vertically overlapped with the regulation precipitation treatment unit at height, so that the hydraulic condition is improved, the flow process is shortened, and the land and the cost are saved.
Description
technical field [0001] The invention belongs to the field of sewage and sludge treatment, and in particular relates to an oily sewage and sludge treatment device and a treatment method thereof, and is especially suitable for the treatment of railway oily sewage. Background technique [0002] At present, in order to make the water quality, quantity and discharge standard of railway oily sewage meet the requirements, the commonly used treatment processes are grille, regulating sedimentation, inclined plate oil separation, and sludge is generally treated by drying field. The current oily sewage treatment separates the treatment units such as grille, regulating sedimentation, inclined plate oil separation, and sludge drying, which occupies a large area, large head loss, and high cost. For the existing railway station sections, the contradiction of land shortage is even more prominent, and this problem has not been well resolved in China for many years. Contents of the inventio...
