Calculation and Assessment of Benchmark Water Footprint of Silk Products
摘要
Abstract
Water footprint is an important tool for evaluating environmental load of water resources . Water shortage footprint and water degradation footprint can be used to evaluate the water environment load of water resource consumption and water pollutant discharge .Based on ISO 14046 and combined with the water quota and water pollution discharge standards ,this paper calculated and assessed the benchmark water footprint in the production nd processing stage of silk products , and analyzed the environment load of water resources of the silk products in the each process stage . The results show that the benchmark water discharge footprint of the silk reeling stage ,dyeing stage and weaving stage is 682 .7 m3 H2 O eq/t ,297 m3 H2 O eq/t and 252 .5 m3 H2 O eq/t .The NH3-N and TN in the wastewater in silk reeling stage as well as AOX and N in the wastewater in the dyeing stage are the main pollutants resulting in eutrophication .The eutrophication footprint of benchmark water is 273 kg PO3-4 eq/t ,255 .78 kg PO3-4 eq/t ,228 kg PO3-4 eq/t ,187 .92 kg PO3-4 eq/t .The sulfide in the wastewater in silk dyeing stage causes water acidification .The acidification footprint of benchmark water is 0 .0033 kg SO2 eq/t .TA has certain water toxicity ,and the toxicity footprint of benchmark water is 0 .28 m3 H2 O eq/t.关键词
