Forbairt ghlas, ag tabhairt aird ar chosc ar thruailliú sa phróiseas déanta páipéar leithris

Is féidir cosc ​​agus rialú ar thruailliú sa phróiseas déanta páipéir leithris a roinnt ina dhá chatagóir: cóireáil fhónta comhshaoil ​​ar an láthair in-gléasra agus cóireáil fuíolluisce lasmuigh den láthair.

Including: ① strengthen the preparation (dust, sediment, peeling, pith, etc.), the use of water film dust collector, reduce dust pollution in the preparation workshop, collection of waste, combustion recovery of thermal energy, such as the use of coirt, sceallóga adhmaid, coire dóire féir; ② water conservation, white water recycling, a number of times the water reuse; ③ to improve the extraction of cooking black liquor, strengthen the management of the counter current washing section to increase the number of sections, reduce the amount of cooking black liquor with the pulp taken away from the wash, and use the perfect cooking waste liquid recovery ceimiceán agus teicneolaíocht fuinnimh theirmeach, amhail aisghabháil alcaile, agus úsáid chuimsitheach leacht dramhaíola eile. Agus úsáid a bhaint as aisghabháil leacht dramhaíola cócaireachta foirfe ceimiceán agus teicneolaíocht fuinnimh teirmeach, mar shampla aisghabháil alcaile, chomh maith le húsáid chuimsitheach eile a bhaint as teicneolaíocht leachtach dramhaíola; ④ chlorine dioxide or oxy-alkali bleaching, or hydrogen peroxide bleaching, in order to reduce the wastewater lignin chloride, chlorophenol and other toxic emissions; ⑤ dirty condensate purified by steam extraction method for reuse to reduce the wastewater emissions of reduced sulfur and soluble organics; ⑥ collection of run-off and dripping black liquor, Green liquid, white liquid, with electronic computer control to measure its concentration, automatically sent back to the corresponding tank percussion, to reduce emissions; ⑦ recovery of lost fibers, reduce the content of suspended solids in wastewater; ⑧ to improve the recovery of turpentine sulphate soap, reduce the emission of toxic substances; ⑨ treatment of solid waste, the use of combustion to recover heat, comprehensive utilization and fill the pit of the three kinds of treatment; ⑩ cóireáil deannaigh is féidir, a úsáid i bhaint deannaigh leictreach, a bhaint deannaigh scannán uisce agus deighilteoir cioclón agus trealamh eile; air pollution processing Separator and other equipment; air pollution treatment, collection of odorous gas in each workshop, including the odorous gas raised by dirty condensation water vapour, after cooling, dehydration, explosion-proof and other measures, sent to the boiler, alkali recovery furnace or lime kiln combustion treatment;? Noise treatment, take measures to eliminate vibration, sound insulation and switch to low-noise equipment.
