Abstract
The invention relates to a treatment method for whitewater produced in papermaking. The method is realized by directly arranging a tungsten carbide film at the position of the pipeline of each pump inlet during whitewater flowing and conveying. By using the method provided by the invention, since the tungsten carbide film can filter wastewater with sewage, titanium dioxide and fiber in the whitewater is prevented from losing; meanwhile, since the filtered wastewater does not contain or contains little titanium dioxide and fiber, the wastewater tends to be neutral, so COD and BOD are beneficial to be reduced.
Description
Technical field
The present invention relates to the plain boiled water processing method in a kind of paper production.
Background technology
At present, the conventional method of the plain boiled water process in paper production is the precipitation method, namely precipitate in sedimentation basin, drain as waste water containing higher titanium dioxide and fiber in the water bottom precipitation after-bay, this method can cause the titanium dioxide in plain boiled water and fiber loss serious, not only long processing period, and treating capacity is little, and mud bottom pond is also difficult, in addition, the waste water of discharge, in alkalescence, causes COD, BOD too high.
Summary of the invention
The object of this invention is to provide and can prevent titanium dioxide in plain boiled water and fiber, reduce plain boiled water filter after waste water COD and BOD a kind of paper production in plain boiled water processing method.
The technical scheme that the present invention takes is: the plain boiled water processing method in a kind of paper production, it is characterized in that the pipeline place when plain boiled water stream send directly at each pumping hole is provided with carbonization tungsten film.
Adopt the present invention, prevent the titanium dioxide in plain boiled water and fiber loss because carbonization tungsten film can filter out the dirty waste water of band, and do not contain or contain a small amount of titanium dioxide and fiber in filtered waste water, waste water is tending towards neutral, is conducive to reducing COD, BOD.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further detail.
Plain boiled water processing method in this paper production is that the pipeline place when plain boiled water stream send directly at each pumping hole is provided with carbonization tungsten film.When plain boiled water is through carbonization tungsten film, titanium dioxide and fiber can not flow through or flow through carbonization tungsten film on a small quantity, then can pass through carbonization tungsten film containing dirty waste water.Therefore, owing to not containing in filtered waste water or containing a small amount of titanium dioxide and fiber, waste water is tending towards neutral, is beneficial to and reduces COD, BOD.
