摘要: The present invention relates to a process of remediating wastewaters, preferably agricultural wastewaters resulting from animal production or contained feeding operation sites. water is treated promote assimilation nutrients into algal biomass, which can be harvested and sold, the resultant wastewater then purified. According invention, short wavelength UV radiation (less than 280 nm wavelength) used pretreat wastewater, with dose determined by absorbance water, not bacterial load. Pretreated exhibits changes in chromophoric dissolved organic matter that allows for improved increased algae as much 88%.
