- Abstract
In utilization of two main washing varieties of a large-scale representative laundry factory-hotel linens and hospital gowns as the research objects, seven evaluation indexes which are chromaticity, turbidity, light transmittance, conductivity, pH value, surface tension and TOC, are applied to wastewater measurement and data analysis under standard assessment criterions. Since turbidity and light transmittance, surface tension and the TOC in characterize water quality are consistency. After the combination of those two pairs of indexes, turbidity and TOC are chosen. Besides, due to the unobvious change in pH data, it can be dispensed with. Finally, chromaticity, turbidity, TOC and conductivity are selected as the water-quality evaluation indexes of laundry wastewater for scale laundry factory.
