Waste gas and wastewater treatment system for electroplating industry

Abstract

The invention discloses a waste gas and wastewater treatment system for electroplating industry. The waste gas and wastewater treatment system comprises a waste gas treatment part and a wastewater treatment part and is characterized in that an air suction hood of a hood structure is arranged at the upper end of an electroplating workshop, provided with an air outlet and connected with a waste gas pipeline through the air outlet, a valve structure is arranged at the lower end of the electroplating workshop, and the electroplating workshop is connected with a waste water discharge pipeline through a valve. By the waste gas and wastewater treatment system, the waste gas treatment of the electroplating industry is allowed to conform to national emission standards, the heavy metal ion emission of the electroplating industry conforms to national standards, and environment quality is improved.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a waste gas and wastewater treatment system for the electroplating industry. Background technique [0002] The electroplating industry is an important processing industry at present, which can change the chemical and physical parameters of the workpiece surface. Electroplating is mainly concentrated in the electronics, machine manufacturing, instrumentation, aviation and other industries. layer, but the electroplating industry is also a high-consumption and high-pollution industry. During the electroplating process, acid gases, organic waste gases and heavy metal waste gases will be generated. If they are discharged directly, they will pollute the atmosphere, and the electroplating process is heavy. The electroplating washing liquid contains a lot of heavy metals. In industrial wastewater, heavy metals have high stability and are difficult to degrade in water bodies. When ...

[0002] The electroplating industry is an important processing industry at present, which can change the chemical and physical parameters of the workpiece surface. Electroplating is mainly concentrated in the electronics, machine manufacturing, instrumentation, aviation and other industries. layer, but the electroplating industry is also a high-consumption and high-pollution industry. During the electroplating process, acid gases, organic waste gases and heavy metal waste gases will be generated. If they are discharged directly, they will pollute the atmosphere, and the electroplating process is heavy. The electroplating washing liquid contains a lot of heavy metals. For industrial wastewater, heavy metals have high stability and are difficult to degrade in water bodies, and if they accumulate to a certain extent, they will cause serious harm to fish, shrimp and other aquatic plants.

[0003] The enterprises in the existing electroplating industry are small in scale and are all processing and supporting enterprises with a large number. It is difficult to meet the environmental protection standards, and it is difficult for the environmental protection department to comprehensively monitor. Therefore, the invention provides a waste gas and wastewater treatment for the electroplating industry The system makes the waste gas and wastewater treatment effect better, occupies a small area, and the environmental protection environment of the electroplating industry is improved.
