Embodiment
The utility model provides a kind of waste water circulation system of pcb board production process, and is clearer, clear and definite for making the purpose of this utility model, technical scheme and effect, below the utility model further described.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
The waste water circulation system of the utility model pcb board production process, as shown in Figure 2, comprise pickler 100, for the first time water washing device 110, sandblast apparatus 120, for the second time water washing device 130, ultrasound cleaning device 140 and water washing device 150 for the third time, the water outlet of described for the third time water washing device 150 directly is connected with the water-in of water washing device 130 second time; Described second time water washing device 130 water outlet by one be used for to waste water carry out simple tractable Simple treatment device 160 with the first time water washing device 110 water-in be connected; Water washing device 110 water outlet was used for that by one waste water is carried out the Integrated Processing Unit 170 of integration unit and was connected with the water-in of water washing device 150 for the third time described first time.So, for the third time the waste water of water washing device 150 with direct reuse to water washing device 130 for the second time; For the second time the waste water of water washing device 130 then through simple and easy processing reuse to water washing device 110 for the first time; And the waste water of water washing device 110 is through reusing synthesized extremely for the third time water washing device 150 for the first time.Thereby the waste water of realizing each water washing device passes through different processing mode reuses to production process, and can all not come waste water is purified and reuse through complicated comprehensive treatment mode as traditional way.
Main thought of the present utility model is that the waste water for different operations has connected purifying processing device in various degree, for example, waste water for for the third time water washing device 150 generations, water quality is relatively better, and water washing device 130 waters are so not high to water quality requirement for the second time, so the water outlet of the waste water that water washing device for the third time 150 can be produced directly is connected to for the second time water-in of water washing device 130 by pipeline, thereby make said process need not waste water is processed, saved a large amount of processing costss and water cost; Waste water for the water washing device 130 generations second time, its water quality is relatively relatively poor, need through after some simple and easy processing, the wastewater effluent mouth of the water washing device 130 generations second time can be connected a Simple treatment device 160 makes purification of waste water totally and is connected to for the first time water-in of water washing device 110 by pipeline, this process need carries out simple and easy processing to waste water, and treatment process is without too complex; And for waste water that the first time, water washing device 110 produced, its water quality extreme difference, contain a large amount of impurity, needing could be clean with purification of waste water through a series of complicated purification process technique, so, with the first time water washing device 110 water outlet through after the comprehensive treating process, be connected to for the third time water-in of water washing device 150 by pipeline again.
By above-mentioned three kinds of targetedly wastewater treatment modes, realized the zero release of waste water, under the perfect condition, the usage quantity of clean water can be zero, and the wastewater discharge of every day also is zero.
In the utility model, 160 li of Simple treatment devices can comprise that some carry out the non-chemically device of reaction treatment to waste water, and the filtration unit and the settler that for example waste water are filtered, precipitates are processed a small amount of impurity totally getting final product.Integrated Processing Unit 170 then needs complicated treatment unit, a series of processing such as the coagulation reaction device that connects successively, settler, pH setting device, supercharging device, fiber filter treatment unit, activated carbon filtration treatment unit, positively charged ion softening installation, precise filtering device, reverse osmosis unit, and carry out metal smelting for independent recovery of the waste liquid needs that contain plurality of heavy metal, but other waste liquid and waste water then centralized collection get up, and carry out above-mentioned integrated disposal processing.Some concrete treatment process of above-mentioned simple and easy processing and comprehensive treating process can with reference to technique of the prior art, not given unnecessary details at this.
By adopting the waste water circulation system of the utility model pcb board production process, wastewater recycle rate improves greatly, and wastewater recycle rate is up to 75% after tested.In the actual production process, producing area according to 50SF PCB calculates, every day, water of productive use was 1500T, be 250T with the waste water direct reuse of water washing device 150 for the third time to the reuse water of water washing device 130 for the second time, with the second time water washing device 130 waste water be 450T through simple and easy processing reuse to the reuse water of water washing device 110 for the first time, with the first time water washing device 110 waste water through reusing synthesized to the reuse water of water washing device 150 for the third time be 300T, like this, total wastewater recycle rate reaches 67%.
A specific embodiment of the wastewater recycling system of the utility model pcb board production process, it is the PHT pretreatment line, under normal circumstances, as shown in Figure 3, this PHT pretreatment line comprises the devices such as polish-brush 200, high-pressure washing 210, ultrasound washing 220, middle washing 230, circulating water wash 240, discharging 250, like this, namely comprise three road water-ins and three road water outlets at the PHT pretreatment line, be respectively water-in and the water outlet of high-pressure washing, middle washing and circulating water wash device.Because the function of PHT processing procedure is space of a whole page alligatoring with pcb board, hole wall foreign matter behind the while wash boring, pcb board also will clean its surface when entering next processing procedure, so this PHT pretreatment line is less demanding to quality of water, so can process the waste water that the PHT pretreatment line produces according to thinking of the present utility model.
Specifically as shown in Figure 3, waste water at circulating water wash device 240 does not discharge, and direct reuse is to middle water washing device 230, waste water process Simple treatment device 260 reuses that middle water washing device 230 produces are to high pressure water cleaning device 210, like this, the water inlet of high-pressure washing device 210 has changed reuse water into by tap water, and the water outlet of high-pressure washing device 210 can be through reuse behind the Integrated Processing Unit 270 to circulating water wash device 240, so, the actual Water usage of this PHT pretreatment line is zero, and wastewater discharge is zero.
In addition, the utility model also can be used for processing more reuse water, the waste water reclamation rate is further improved, but this process need consider processing cost, selects best processing mode.
The wastewater recycling system of the utility model pcb board production process, carry out in various degree purifying treatment by the waste water for different quality, thereby reduced the cost of wastewater treatment, improved the rate of recovery of waste water, also can not pollute environment, have high practicality.
Should be understood that; application of the present utility model is not limited to above-mentioned giving an example; for those of ordinary skills, can be improved according to the above description or conversion, all these improvement and conversion all should belong to the protection domain of the utility model claims.
