Wastewater treatment device for treating sludge containing mercury

Abstract

The invention provides a wastewater treatment device for treating sludge containing mercury and belongs to the technical field of wastewater treatment. The device includes a flocculation box and an active carbon filter. A flocculant inlet and a wastewater inlet are arranged on a top cover. A motor is arranged on the top cover and is connected with a rotary shaft, of which the lower end is extendedinto the flocculation box. A stirring shaft is connected to the rotary shaft. A delivery pipe is connected between the lower end of a delivery cylinder and the top surface of a bottom cover. A rotating shaft is arranged on the middle part of a side wall of the delivery pipe and is provided with a screen frame. The edge of the screen frame is contacted with the inner side wall of the delivery pipe. A filter screen is arranged in the screen frame. A motor is disposed on a first support plate. The terminal of the rotating shaft is connected to the motor. An electric telescopic cylinder is arranged on a second support plate. A separation board is connected to the telescopic rod of the electric telescopic cylinder and can be installed on a separation board mounting port. A water feeding pipe is connected between a water outlet and a water feeding end of the active carbon filter. The device is high in water purification efficiency.

Description

Technical field: [0001] The invention belongs to the technical field of wastewater purification, and in particular relates to a wastewater treatment device for treating mercury-containing sludge. Background technique: [0002] Existing wastewater from industrial mercury-containing sludge contains impurities and unpleasant odors, and is discharged into the external environment to seriously pollute the environment. Existing wastewater treatment devices have the problem of low purification efficiency in treating wastewater, which cannot meet the requirements of wastewater treatment. Therefore, a wastewater treatment device with high purification efficiency for treating mercury-containing sludge has been developed. Invention content: [0003] The object of the present invention is to provide a wastewater treatment device for treating mercury-containing sludge in view of the above existing problems, and the wastewater treatment device for treating mercury-containing sludge has ...
