摘要
结合国标《城市污水再生利用农田灌溉用水水质》的制定,探讨了我国城市污水再生回用于农田灌溉的基本控制指标的筛选及定值依据。确定的水质控制指标包括:生化需氧量、化学需氧量、悬浮物、溶解氧、游离余氯、挥发酚、LAS等一般化学指标;汞、镉、砷、铬(六价)和铅等毒理学指标;粪大肠菌群数和蛔虫卵数等卫生学指标。参考国内外相应标准,并结合我国再生水用于农田灌溉的实际情况,提出了各基本控制指标的最大限值。
According to the national standard The Use of Urban Reclaimed Water-Quality of Farmland Irrigation Water, the key point of prime control indexes and determining maximum limited value of the toxic substances in reclaimed water from municipal wastewater for farmland irrigation were discussed. BOD, COD, SS, DO, free residual chlorine, volatile phonol, LAS as general chemical indexes, Hg, Cd, As, Cr （Ⅵ） and lead as toxicological indexes, fecal coliform and ascaris egg number as hygienic indexes were determined as the prime control indexes. Reference to the related criteria of foreign countries, combined with the real status of municipal wastewater for farmland irrigation in China, the maximum limited values of the prime control indexes were given.
