Steel mill sewage treatment equipment with good purification effect

Abstract

The invention discloses steel mill sewage treatment equipment with good purification effect, belonging to the field of sewage treatment equipment. The steel mill sewage treatment equipment comprises asewage deironing chamber and a precipitating adsorption chamber, wherein an upper end cover is arranged at the top end of the sewage deironing chamber, and an deironing device is arranged in the sewage deironing chamber; the upper end cover is fixedly connected with the top end of the sewage deironing chamber through a nut and a bolt which are screwed togerher, and a water inlet pipe is arrangedon the upper end cover; a plurality of flow guide rods are symmetrically distributed at the lower end of a cylinder; the precipitating adsorption chamber is arranged on the right side of the sewage deironing chamber, and a sealing partition board is arranged in the precipitating adsorption chamber; and an activated carbon layer and a biological reaction layer are arranged in an adsorption cavity.The steel mill sewage treatment equipment is reasonable in structural design and convenient to use; by arranging the deironing device, ferromagnetic substances in sewage can be effectively removed; and by arranging the precipitating adsorption chamber, sewage can be treated through precipitation and adsorption, so that the treatment quality of steel mill sewage can be guaranteed.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to sewage treatment equipment for steel mills with good purification effect. Background technique [0002] At present, in the continuous casting and rolling production process of steel mills, the direct cooling water and dust removal wastewater in the secondary cooling zone generally contain a large amount of iron oxide scale, grease, dust and other intermediates and pollutants. When rolling steel, there is also a large amount of direct cooling water, which constitutes the turbid ring water system in the steel plant water treatment; many steel plant water can be recycled, but many companies do not pay attention to it, or due to filtration and other equipment The price is relatively expensive, and the maintenance is more troublesome, so many enterprises use disposable water, which is undoubtedly a waste of water resources and will bring some pollution to the environment; the...
