Problems solved by technology

[0004] At present, electroplating wastewater treatment methods are mostly treated by chemical and physical methods. The addition of chemical agents will cause secondary pollution to wastewater treatment. Physical adsorption has a better treatment effect, but most of the adsorbents cannot be reused, resulting in a serious waste of resources.

Abstract

The invention discloses an electroplating wastewater treatment system, which includes a plant cultivation device, a primary treatment device, a centrifugal separation device, an electric Fenton oxidation device and an advanced treatment device. The invention includes a plant cultivation device, a primary treatment device, a centrifugal separation device, an electric The Fenton oxidation device and advanced treatment device, through the adsorption of chlorella to heavy metal ions, conduct preliminary treatment of electroplating wastewater through primary treatment, and then undergo electro-Fenton oxidation and nanofiltration membrane advanced treatment to make the effluent quality meet the standard discharge and return It is applied to a plant cultivation device, and the electric Fenton oxidation adopts an iron plate anode, and at the same time, it is supplemented by microporous aeration as the electric Fenton gas source, without adding oxidants and iron ions. The present invention adopts physical treatment and electric Fenton oxidation technology, and the cost Low, no secondary chemical pollution, friendly to the environment, and can realize efficient treatment of electroplating wastewater.

Description

technical field [0001] The invention relates to an electroplating wastewater treatment system, which belongs to the technical field of wastewater treatment. Background technique [0002] Electroplating is the use of chemical and electrochemical methods to coat various metals on the surface of metals or other materials. Electroplating technology is widely used in machine manufacturing, light industry, electronics and other industries. The quality of electroplating sewage is complex. Electroplating sewage contains heavy metal ions such as chromium, zinc, copper, nickel, and cadmium, as well as highly toxic impurities such as acid, alkali, and cyanide. The composition of electroplating sewage is complex, and the pollutants can be divided into two categories: inorganic pollutants and organic pollutants. The water quality varies greatly. If it is directly discharged without treatment, it will cause great pollution to the surrounding water bodies. [0003] Patent CN108203178A de...
