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 wastewater recycling and in particular discloses an electroplating wastewater treatment recycling system. The reverse osmosis wastewater treatment system comprises a source water tank and a reverse osmosis device connected behind the source water tank, wherein a wastewater pretreatment device is arranged between the source water tank and the reverse osmosis device; a water production tank and a concentrated water tank are respectively connected behind the reverse osmosis device; an explosion-proof membrane is arranged on the outer surface of the reverse osmosis device; a water outlet and a water inlet are formed in two ends of the reverse osmosis device; check valves are arranged at the water outlet and the water inlet; and a low-temperature vacuum concentration device is connected to the rear of the concentrated water tank. Circuit board wastewater is economically and effectively treated and recycled and strictly classified, collected and treated,and the recycled clean wastewater is independently recycled, so that the key point whether the wastewater recycling system can be stably operated is ensured. Pollution discharge fees of the wastewater are greatly reduced, and the wastewater recycling system has excellent market prospects 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...
