Embodiment 1

[0018] Example 1 This example discloses a treatment and recycling system for electroplating wastewater. The reverse osmosis wastewater treatment system includes a source water tank 1 and a reverse osmosis device 2 connected thereto. The source water tank and the reverse osmosis device A waste water pretreatment device 10 is also arranged between, and after the reverse osmosis device 2, two produced water tanks 3 and a concentrated water tank 4 are connected; the outer surface of the reverse osmosis device 2 is provided with an explosion-proof membrane, and the reverse osmosis device A check valve 6 is set at the water outlet and the water inlet. The volume of the produced water tank 3 is 50m 3 . The water production tank 3 is provided with a water inlet pipe, a water outlet pipe, an overflow pipe, an emptying pipe, a breathing pipe and an interface flange. There are two source water pools 1, the order is the first source water pool and the second source water pool, the volum...

Abstract

The invention belongs to the field of waste water recycling and specifically discloses a treatment and recycling system for electroplating waste water. The reverse osmosis waste water treatment system includes a source water pool and a reverse osmosis device connected thereafter. The source water pool and the reverse osmosis device A waste water pretreatment device is also arranged between them, and the reverse osmosis device is respectively connected with a produced water tank and a concentrated water tank; the outer surface of the reverse osmosis device is provided with an explosion-proof membrane, and the two ends of the reverse osmosis device are provided with water outlets and the water inlet; the water outlet and the water inlet are provided with check valves; the concentrated water tank is also connected with a low-temperature decompression concentration device. Economical and effective treatment and reuse of circuit board wastewater, strict classification collection and treatment, and separate reuse of reusable cleaning wastewater are the key to ensuring the stable operation of the wastewater reuse system. The waste water sewage discharge fee is greatly reduced; it has great market prospect and economic value.

Description

technical field [0001] The invention belongs to the field of waste water recycling and specifically discloses an electroplating waste water treatment and recycling system. Background technique [0002] At present, the circuit board production process mainly includes cutting, grinding, wiring, etchant, developing, stripping, electroless copper plating, gold plating, circular electroplating and other processes. The wastewater discharged from each production process contains not only heavy metal ions such as Cu, Ni, Sn, but also complexing agents such as EDTA and sodium tartrate. At the same time, it also contains high-concentration organic wastewater and waste liquid such as developer, degreasing agent, and expansion agent. In addition, in the production process, a large number of various patented commercial reagents are used, so that the organic matter contained in the circuit board production wastewater often reaches hundreds of species. Moreover, a large amount of chemica...
