宾馆污水多目标回用与零排放处理工艺

Research on Multi-purpose Reuse and Zero Discharge of Hotel Wastewater

采用微氧、好氧与富氧生物处理一体化集成工艺及后续气浮、过滤、活性炭吸附与UV消毒优化组合工艺处理宾馆污水。在进水COD为428 mg/L、pH值为7.1、氨氮为22.8 mg/L、总磷为5.9 mg/L、SS为125 mg/L、色度为120倍、LAS为1.46 mg/L的条件下,处理系统气浮工艺的出水COD、pH、浊度和色度等各项水质指标均满足绿化用水要求,过滤工艺的出水水质指标满足洗车用水要求,活性炭工艺的出水水质指标满足景观用水要求,从而实现了零排放与多目标回用。

The integrated process of micro-oxygen, aerobic and oxygen-rich biological treatment as well as the subsequent optimized combined process of flotation, filtration, activated carbon adsorption and UV disinfection were used to treat hotel wastewater. Under the conditions of the influent COD of 428 mg/L, pH of 7.1, ammonia nitrogen of 22.8 mg/L, total phosphorus of 5.9 mg/L, SS of 125 mg/L, color of 120 times and LAS of 1.46 mg/L, the flotation effluent quality meets the requirement for greening water, the filtration effluent quality meets the requirement for car washing water, and the activated carbon effluent quality meets the requirement for landscape water, thus the zero discharge and multi-purpose reuse are realized.
