Abstract
A biochemical sludge and physicochemical sludge separate sampling device for identifying attributes of sludge, includes a sludge extraction assembly, and a biochemical reaction tank and a physicochemical reaction tank which are respectively connected to the sludge extraction assembly through connection pipelines. The sludge extraction assembly includes an outer shell, a porous plate clamped to an inner bottom of the outer shell, and a sampling dish. A drain pipe is arranged at a lower end of the outer shell. The sampling dish is provided with a biochemical sludge cavity and a physicochemical sludge cavity. Filter cloth is arranged at inner bottoms of the biochemical sludge cavity and the physicochemical sludge cavity. Electric extrusion stems are arranged at an inner top of the outer shell; and the electric extrusion stems are provided with extrusion plug plates.
