Abstract
The invention relates to a waste reducing system and a method in the field of electronic information printed circuit boards. The invention solves the problems of strong corrosivity, high water content and difficult incineration in existing high-alkalinity water membrane slag, and provides a system and a method convenient for incineration after neutralizing and reducing water content. The technical scheme is as follows: acidic wastewater and high-alkalinity membrane slag are dehydrated by adopting a water control system after being neutralized. The system and the method have the following benefits: the high-alkalinity membrane slag can be neutralized, the water content is reduced, the reduction of membrane slag wastes is realized, and the wastes are conveniently incinerated, so that the treatment cost of the wastes is decreased.
Description
Technical field
The present invention relates to the system and method for the minimizing discarded object in a kind of electronic information printed substrate field.
Background technology
In recent years, information, communication, automobile and consumption electronic products manufacture had become whole world growth one of industry the most fast already, impel the World PCB output value to increase year by year, cause high alkalinity film slag output also more and more higher, offal treatment expense increases, cause environmental pollution simultaneously, therefore solve existing high alkalinity and there is severe corrosive containing moisture film slag, moisture content is high, be difficult for the problem of burning, a kind of neutralization is provided, after reduction moisture content, be convenient to the system and method burning, not only can save huge offal treatment expense, can also reduce environmental pollution, reach the target of economic benefit and environmental protection doulbe-sides' victory.
In view of this, how reducing high alkalinity film slag, is that environmental protection personnel need a problem of solution badly in the industry.
Summary of the invention
In existing green technology, by existing high alkalinity containing moisture film slag there is severe corrosive, moisture content is high, is difficult for the problem of burning, the invention provides a kind of neutralization, reduce and be convenient to the system and method that burns after moisture content.
According to discarded object loss of weight system provided by the invention and aspect, in acid waste water and high alkalinity film slag, dewatered with rear employing control water system, it is characterized in that, comprising:
1) N-process: acid waste water (PH:1～2) regulates PH to 6 with high alkalinity film slag (PH:11～12) neutralization, and acid waste water and high-alkali film slag ratio example are 20: 1;
2) control water process: in acid waste water and high alkalinity film slag and after, high alkalinity film slag becomes loose lenticular from sticky shape, internal density reduction, by gauze by its Separation of Solid and Liquid;
The operation of being more convenient for: neutralization pond bottom needs gate valve, to after acid waste water fully reacts with high-alkali film slag, open gate valve, acid waste water and film slag flow to top, control pond and place one and become the 30 husky nets of spending inclination, by its Separation of Solid and Liquid.
Adopt the present invention to efficiently solve existing high alkalinity and there is severe corrosive, high, the difficult problem of burning of moisture content containing moisture film slag, and have cost-saving and function environmental protection concurrently.
Brief description of the drawings
Reader, after having read the specific embodiment of the present invention with reference to accompanying drawing, will become apparent various aspects of the present invention, wherein,
Fig. 1 shows according to operation chart of the present invention.
Detailed description of the invention
With reference to the accompanying drawings, the specific embodiment of the present invention is described in further detail.
Fig. 1 shows according to operation chart of the present invention.With reference to Fig. 1, acid waste water and high alkalinity film slag in 20: 1 ratios in neutralization pond hybrid reaction, regulate PH be 6 and high alkalinity film slag after sticky shape becomes loose lenticular, open gate valve, solidliquid mixture flows to top, control pond and is 30 ° of gauzes, Separation of Solid and Liquid, and liquid flows into control pond, and flow into waste water processing station by pipeline, the collection and treatment of semisolid films slag woven bag
Adopt advantage of the present invention be can effectively solve high alkalinity containing moisture film slag there is severe corrosive, moisture content is high, is difficult for the problem of burning, and neutralizing acid wastewater, not only can reduce discarded object and acid waste water processing cost, also can reduce the pollution to environment.
Above, describe the specific embodiment of the present invention with reference to the accompanying drawings.But those skilled in the art can understand, without departing from the spirit and scope of the present invention in the situation that, can also do various changes and replacement to the specific embodiment of the present invention.These changes and replacement all drop in the scope of the claims in the present invention book restriction.
Claims (3)
1. discarded object abatement system and a method, is characterized in that, comprising:
N-process: acid waste water (PH:1～2) regulates PH to 6 with high alkalinity film slag (PH:11～12) neutralization, and acid waste water and high-alkali film slag ratio example are 20: 1;
Control water process: in acid waste water and high alkalinity film slag and after, high alkalinity film slag becomes loose lenticular from sticky shape, internal density reduction, by gauze by its Separation of Solid and Liquid.
2. discarded object loss of weight system and method as claimed in claim 1, is characterized in that, more comprises that easy to operate neutralization pond bottom needs gate valve, to after acid waste water fully reacts with high-alkali film slag, open gate valve, acid waste water is controlled pond with the film slag flow direction.
3. as claimed in claim 2, after acid waste water reacts with film slag, flow to control pond, a husky net that becomes 30 degree to tilt is placed in top, control pond, by its Separation of Solid and Liquid.
