Abstract

The invention belongs to the technical field of water treatment, and discloses chromium electroplating wastewater treatment system and method. The chromium electroplating wastewater treatment system comprises a chromium electroplating wastewater storage tank, multiple layers of grid plates, an outer cover, an air filter, a Roots blower and an electroplating washing water tank, wherein the outer cover covers a position above the chromium electroplating wastewater storage tank; the lower part of the left side of the chromium electroplating wastewater storage tank is connected with a water pump through a pipeline; the multiple layers of grid plates are welded in the outer cover through brackets; the front of the outer cover is provided with an air inlet; the air inlet is in bolted connectionwith the air filter; the back of the outer cover is provided with an air outlet; the air outlet is connected with the Roots blower through a vapor pipeline; an air outlet of the Roots blower is connected with a flow divider at the bottom of the electroplating washing water tank through a pipeline. The chromium electroplating wastewater treatment system sufficiently utilizes an industrial production residual heat medium, is used for treating chromium salt electroplating wastewater, is used for decreasing a cost and improving a benefit, and has the advantages of being a few in investment, low intreatment cost and simple to operate, and the like.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a treatment system and method for electrochrome plating wastewater. Background technique [0002] At present, the treatment methods of electroplating wastewater at home and abroad mainly include: ①Chemical precipitation method: Chemical precipitation method is a method to convert the dissolved heavy metals in the wastewater into water-insoluble heavy metal compounds, including neutralization precipitation and sulfide precipitation. ②Ion exchange method: Ion exchange method is a method of separating harmful substances in wastewater by using ion exchangers. When wastewater containing heavy metals passes through the exchanger, the ions on the exchanger exchange with the metal ions in the water to achieve the purpose of removing metal ions in the water. ③ Electrolysis method: Electrolysis method is to use the electrochemical properties of metals to remove metal io...
