Abstract

The invention relates to the technical field of wastewater treatment, in particular to metallurgical wastewater treatment equipment. A metallurgical wastewater treatment equipment includes a wastewater treatment system and a filter device, the filter device includes a casing, a lower cylinder, a solid-liquid separation device, a rotating filter screen assembly, a blocking device, and a plurality of upper spring bars. The rotating filter screen assembly can move up and down and is rotatably arranged in the shell, and is above the sewage outlet. The blocking device is used to block the sewage outlet, so as to move and rotate downward with the rotating filter screen assembly to open the sewage outlet; The liquid separation device can be slid up and down in the casing. The upper end of the upper elastic bar is connected to the solid-liquid separation device, and the lower end is connected to the rotating filter screen assembly; the upper end of the lower elastic bar is connected to the rotating filter screen assembly, and the lower end is connected to the water outlet pipe to realize the filter device. It can automatically discharge sewage when it is blocked by large particles of impurities.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to metallurgical wastewater treatment equipment. Background technique [0002] Metallurgy is the process and technology of extracting metals or metal compounds from minerals, and using various processing methods to make metals into metal materials with certain properties. Metallurgical wastewater contains a large amount of suspended solids, the water quality changes greatly, and the water temperature is relatively high. For every 1 ton of molten iron produced, 2 to 4 m should be discharged 3 Blast furnace gas washing wastewater, the water temperature is above 30°C, the suspended matter content is 600-3000mg / L, mainly iron ore, coke powder and some oxides, and also contains cyanide, sulfide, phenol, inorganic salt and zinc, For metal ions such as chromium, the treatment method is to use a filter device to remove particles with a particle size above 100 microns, and the...
