Abstract

This paper introduced the processing of the domestic and international livestock wastewater. The actuality of environmental problems caused by livestock husbandry was discussed and the relationship between husbandry and sustainable development was remarked on. From the point of ecosystem, dealing with livestock wastewater harmlessly with bio-filtration system is advised. A bio-filtration system is set up based on the analysis of a typical and simple water treatment system. The system mainly consists of a solid removal basin and a planting filter. We elect ryegrass as the planting-filter, because it gets best sod, mechanic filtration and bio-filtration. Effects of static bio-filtration were studied in ryegrass. Under this system, to achieve preferable purification efficiency, the wastewater concentration and the area of planting which suited for pasture growth will be provided. Near infrared spectra was used to analyze the water quality, about chemical oxygen demand (CODcr). A set of 20 samples of livestock wastewater with different concentrations was taken from the Animal Institution of Zhejiang Agricultural Science Organization, and the partial least square (PLS) was used to develop predictive models. To validate these models, some samples were used. SEP were 22, 32 and r² values using the validation set of data were 0.9895, 0.9985 for COD of wastewater.
