Description
Technical field
The present invention relates to field of sludge treatment, specifically a kind of paper mill sludge medicament.
Background technology
In paper making process, sludge is turned into after a large amount of tiny fiber loss, number of dropouts accounts for the 6- of papermaking yield
6.5%, and the surface area of these fiber fines is greatly and all organic matter, for a long time will be by anaerobic bacteria pollution in water body
Become sludge, form solid waste, substantial amounts of raw material is wasted, it is often more important that solid waste also severe contamination environment.
Existing paper mill sludge processing method includes：First, transported outward after moisture content in solid waste is removed 25-40% by filter press and filled out
Bury and burn, this method had not only wasted raw material but also polluted underground water and air；Second, solid waste is manufactured into mud-guard, OK
Industry produce sludge quantity about use 30%, added value is also very low, rate of gross profit about 15%, remove processing charges after profit only about
2%, it is still landfill and burning to 70% unnecessary solid waste because mud-guard market demand is very small, equally it is wave
Take resource and pollution air；3rd, solid waste is processed as farmland organic fertilizer, because there are substantial amounts of poultry, domestic animal in rural area
Professional raiser's fertilizer and chemical fertilizer, and these fertilizer in quality than solid waste processing organic fertilizer it is high, from price will
It is lower than this kind of fertilizer, it is difficult to realize promoting, as a result still fill and burn；4th, in production system, use macromolecule organic
Polyacrylamide carries out retention, a part of solid waste is kept in page, but in adding procedure 50% escapement ratio all
In system water, production system reclaimed water concentration C OD, SS, inorganic salts, electrical conductivity etc. is increasingly raised, cause production yields, quality
Decline, the vicious circle in water system of escape sludge, increase wastewater treatment pressure, enterprise to shipwreck after treatment with up to standard, to surplus
Remaining sludge or press filtration landfill and burning.These are all for manufacturer brings inconvenience.
