Technical field
The present invention relates to a kind of technology of making paper pulp, particularly relate to the combined production process for ecological paper pulp of Zero-discharge non-pollution.
Background technology
The pollution of whole world paper industry is the headachy thing of part at present, on the one hand being the international market is increasing year by year to the demand of paper, especially the Chinese market consumption figure is every year on average with 12% constantly increasing at a high speed, the pollution condition that is paper industry on the other hand is in continuous deterioration, and the main source of each big river of China, lake water pollution is a paper industry.1989 because the contaminated color of soy sauce that almost become of Huaihe River water quality, force Chinese Government disposable Basin of Huaihe River more than the 2000 tame middle-size and small-size paper mills of having closed of ordering, but after several years, the Huaihe River water that take a favorable turn slightly again gradually become color of soy sauce, river can not be used for irrigating, and can not drink, and fish is death ray also, this is because some irresponsible papermaking producers do not process just the stealthily result of discharging for economic interests to the waste liquid of pulp production.But after all basic reason is that present paper industry all is applied chemistry pulp-making method (pollution of paper industry mainly is in the slurrying stage) basically.Use alkaline process, sulphite process or acid polishing, what acid polishing was discharged is red waste liquid, what alkaline process and sulfite pulping were discharged is the black waste liquid, contain a large amount of lignins and the catabolite of carbohydrate in these waste liquids that are discharged, as vulcanize lignin, formic acid alcohol, dimethyl sulphide and Methyl disulfide compound etc., this all is the compound that can give out foul smell, this just makes in the waste liquid of pulping and contains very high COD (COD), biochemical oxygen demand (BOD) (BOD), suspended matter (SS) and adsorbable organohalogen compounds (AOX), the bleaching process of paper pulp mostly is to adopt the chlorine bleach technology, contain more than 40 kind of organochlorine compound in the waste liquid that bleaching is discharged, comprising the carcinogenic noxious material of dioxin and so on.According to " Chinese paper industry 2002 annual reports ", the paper industry wastewater discharge reaches 31.9 hundred million tons, account for national industrial total release 17.4%, wherein the discharge capacity of chemical oxygen demand COD accounts for 40.8% of national industrial wastewater pollution thing discharge capacity, though the continuous booster injection of national environmental protection department is to the controlling index of paper industry blowdown and strengthen regulatory efforts, paper industry self also continues to increase the measure and the investment of administering sewage, R﹠D institution is also constantly providing new pollution treatment technology and method, this all makes the sewage discharge of China and world's paper industry obtain improvement year by year really, no matter how advanced but problem is: pollution treatment technological means and process equipment, the sewage discharge that all can't thoroughly effect a radical cure paper industry reaches zero and pollutes, and makes our living environment constantly be subjected to the injury of papermaking blowdown.
