Abstract

The invention discloses a kind of processing method of paper waste, specific processing method is as follows：Pulp-making waste-water：It is slurried in fiber, production waste water that the pulping process such as pulp washing screening generate is by being immediately discharged to sewage plant processing after the filtering of thin mechanical grille；Wastewater from paper machine：In process of production, the plain boiled water turbidity deviate from by wire-cloths is higher, wherein the plain boiled water of this part abjection can recycle in production after filtering containing a large amount of fibers etc.；Boiler dusting waste water：It can be recycled completely after the neutralized precipitating of the waste water, need to only supplement a small amount of loss water.The pulp-making waste-water generated in production by being filtered heel row to Sewage Disposal processing through thin mechanical grille by the present invention, it can be to avoid pollution discharging outside high density pollution substance, and high density pollution substance is not present in the sewage in the production of wastewater from paper machine, boiler dusting waste water these two types, it can be reused after filtering or precipitating completely in production, be conducive to save water resource, to save production cost.

Description

A kind of processing method of paper waste

Technical field

The present invention relates to the technical field of paper waste more particularly to a kind of processing methods of paper waste.

Background technique

In paper machine room, mainly generating pulp-making waste-water, wastewater from paper machine, boiler dusting waste water in process of production, this is three big Class produces waste water, is mostly to use to concentrate to be pooled at sewage to this three categories production waste water in present workshop processing exhaust gas network Processing in reason station, causes unnecessary water resource waste, therefore, it is necessary to propose a kind of processing method of paper waste in this way.

Summary of the invention

For the defect for solving prior art, the invention discloses a kind of processing methods of paper waste.

The invention discloses a kind of processing method of paper waste, specific processing method is as follows：

（1）Pulp-making waste-water：It is slurried in fiber, the pulping process such as pulp washing screening generate and contain solid, organic matter, CODcr, BOD Etc. high concentrations polluter production waste water, this part producing waste water by thin mechanical grille filter after be immediately discharged to sewage plant Reason；

（2）Wastewater from paper machine：In process of production, the plain boiled water turbidity deviate from by wire-cloths is higher, wherein containing a large amount of fine The plain boiled water of dimension etc., the abjection of this part can recycle in production after filtering；

（3）Boiler dusting waste water：The waste water major pollutants are PH, suspended matter, COD etc., can after such neutralized precipitating of waste water It is recycled completely, need to only supplement a small amount of loss water.

Beneficial effect is：By the way that the pulp-making waste-water generated in production is filtered heel row to Sewage Disposal through thin mechanical grille Processing, can to avoid pollution discharging outside high density pollution substance, and wastewater from paper machine, boiler dusting waste water these two types production in sewage In be not present high density pollution substance, can be reused after filtering or precipitating in production completely, be conducive to save water money Source, to save production cost.

Specific embodiment

Embodiment 1

The invention discloses a kind of processing method of paper waste, specific processing method is as follows：

（1）Pulp-making waste-water：It is slurried in fiber, the pulping process such as pulp washing screening generate and contain solid, organic matter, CODcr, BOD Etc. high concentrations polluter production waste water, this part producing waste water by thin mechanical grille filter after be immediately discharged to sewage plant Reason；

（2）Wastewater from paper machine：In process of production, the plain boiled water turbidity deviate from by wire-cloths is higher, wherein containing a large amount of fine The plain boiled water of dimension etc., the abjection of this part can recycle in production after filtering；

（3）Boiler dusting waste water：The waste water major pollutants are PH, suspended matter, COD etc., can after such neutralized precipitating of waste water It is recycled completely, need to only supplement a small amount of loss water.

Finally it should be noted that：Above embodiments are only to illustrate the present invention and not limit technology described in the invention Scheme；Therefore, although this specification is referring to above-mentioned each embodiment, the present invention has been described in detail, this Field it is to be appreciated by one skilled in the art that still can modify to the present invention or equivalent replacement；And all do not depart from this The technical solution and its improvement of the spirit and scope of invention, should all cover within the scope of the claims of the present invention.

Claims (1)
