Abstract

The invention discloses an electroplating wastewater treatment process and a system thereof, which belong to the technical field of electroplating wastewater treatment. The process comprises the following steps: S1, feeding electroplating wastewater into a membrane chemical reactor, removing suspended matters in the electroplating wastewater; and discharging sludge, S2, enabling the electroplatingwastewater treated in the step S1 to enter an STRO membrane assembly for primary concentration treatment, and feeding the generated penetrating fluid into a recycling water tank; S3, introducing concentrated water generated by the STRO membrane assembly in a DTRO membrane assembly to be subjected to secondary concentration treatment, and sending produced condensate water to the recycling water tank; S4, feeding the concentrated water generated by the DTRO membrane assembly into a low-temperature evaporator, and feeding the generated condensate water into the recycling water tank; and S5, introducing the electroplating wastewater treated by the low-temperature evaporator in an electrolytic cell to be subjected to electrolytic impurity removal and then discharging, and feeding the generatedwaste gas into waste gas treatment equipment to be treated and then discharging. The electroplating wastewater treatment process and the system disclosed by the invention are high in heavy metal removal rate and high in treatment efficiency, and waste gas generated by treatment is also treated while electroplating wastewater is treated.

Description

technical field [0001] The invention belongs to the technical field of electroplating wastewater treatment, and in particular relates to an electroplating wastewater treatment process and system. Background technique [0002] The sources of electroplating wastewater are generally: (1) plating cleaning water; (2) waste electroplating solution; (3) other wastewater, including washing the floor of the workshop, scrubbing plate washing water, condensed water from ventilation equipment, and leakage from plating tanks. Or various tank liquids and drainages of "running, popping, dripping, and leaking" caused by improper operation and management; (4) Equipment cooling water, which has not been polluted except for the temperature rise during use. [0003] In the existing electroplating wastewater treatment technology, the removal of heavy metals is incomplete, the treatment efficiency is low, and the treatment effect is poor. Only the wastewater is treated, and the waste gas generate...
