Technical field
The present invention relates to a kind of treatment system of electroplate rinsing wastewater, but specifically be a kind of online treatment nickel-plating rinsing waste water process system.
Background technology
Waste water rinsing after traditional nickel plating generally is with the waste water after the nickel plating, by pipeline it is collected in together, adopts chemical method to concentrate then and handles, by regulating pH value with Ni
2+Transfer Ni (OH) to
2, flocculation agents such as adding polyacrylamide are handled, and then by precipitation mode, by the strainer filtering separation it are removed again; Nickeliferous mud is sent to professional factory again and refines in the precipitation, and nickel is reclaimed, and the water after will handling simultaneously discharges, and as shown in Figure 1, is the treatment system skeleton diagram of prior art.
Yet, this mode that focuses on, be subjected to reason sedimentations such as discharge to filter bad control, treatment effect is not remarkable, and processing efficiency is lower, its system's cost of investment height, land occupation area are big, working cost is also high, can't realize the reuse immediately of waste water, send associated companies to refine recovery again though the nickel metal in the waste water can be collected by coprecipitation mode, but resource utilization is low, the cost height.
Summary of the invention
The objective of the invention is to overcome traditional treatment technology, provide a kind of processing cost low, recycle the efficient height, can carry out the nickel-plating rinsing waste water treatment system of online treatment waste water.
A kind of Online Processing System of nickel-plating rinsing waste water, the relevant device that comprises the rinsing processing that connects the nickel-plating waste water discharge outlet, it is characterized in that, this nickel-plating rinsing waste water treatment system and nickel plating production line connect and compose looping back of an integral body and are received in the line treatment system, it specifically comprises the following part that is interconnected by pipeline: prefilter, accurate filter, buffer tank, clean-in-place CIP water tank, secondary accurate filter and nanofiltration/reverse osmosis (NF/RO) film, the corresponding pressurization charging pump that also is provided with in the pipeline, the dialyzate of handling through nanofiltration/reverse osmosis (NF/RO) film is by the water spot of use of pipeline connection nickel plating production line, can directly be communicated with the nickel bath of nickel plating production line or be communicated with by the nickel bath of accumulator tank with the nickel plating production line through the concentrated solution of NF/RO film processing.
As further specifying of such scheme, the described former water that enters treatment system also can be provided with the multi-stage countercurrent rinsing device and connect water-in again; Described multi-stage countercurrent rinsing device is generally three grades.
Be provided with charging pump between described buffer tank and the secondary accurate filter; Secondary accurate filter and NF/RO film are handled between the pipeline and are provided with topping-up pump.
Described buffer tank also can be connected with clean-in-place CIP water tank with pipeline between the charging pump, can clean whole piping system as required.
Meanwhile, also be connected with former water filler pipe road and raw water pump on the described prefilter.
The beneficial effect that the present invention adopts the solution of above-mentioned technology to reach is:
One, this treatment system adopts the circular treatment closed loop system that connects and composes an integral body with the nickel plating production line, directly nickel poaching wastewater on the line is handled, and is in time reclaimed useful nickel metal ingredient, and nickel metal recovery rate excellence can be controlled in more than 98%; Simultaneously by purifying treatment to nickel poaching wastewater on the line, with the waste water recycling rinsing on line after handling, a large amount of dischargings of poaching wastewater have been avoided, the water reclamation rate reaches more than 80%, substantially can be outside waste discharge, and waste the nickel plating post rinsing again and handle water, its water quality excellence of treated water has been avoided the waste of resource to greatest extent.
Two, technical scheme floor space of the present invention is little, cost is low, and flow process is short, pipeline is economized, the level of automation height, and the processing efficiency height, processing cost is controlled, helps promoting; And identical thinking can be applied to the processing of waste water after the rinsing of other coating baths.
