摘要
L-乳酸生产废水中含有较高浓度的有机污染物和氨氮,属于难处理的有机废水。结合江西某化工厂L-乳酸生产废水水质情况,采用了预缺氧脱氮/BIOFOR处理工艺,出水水质达到《污水综合排放标准》(GB 8978—1996)的一级标准。
L-lactic acid production wastewater with high-concentration organic pollutants and ammonia nitrogen is a kind of refractory organic wastewater. Combining L-lactic acid production wastewater quality from a chemical plant in Jiangxi Province, the pre-anoxic denitrification/biological filtration oxygenated reactor （BIOFOR） process is used. The effluent quality is able to meet the first class criteria specified in Integrated Wastewater Discharge Standard （GB 8978 - 1996）.
