- 摘要:
- 针对江苏省某纺织园区印染废水水质波动大、可生化性差的问题，采用AO/MBR+臭氧催化氧化+曝气生物滤池（BAF）工艺，确保出水达到《城镇污水处理厂污染物排放标准》（GB 18918—2002）一级A标准。处理后的出水分为两部分：一部分作为低端回用水直接回供至园区企业；另一部分经超滤（UF）+反渗透（RO）深度处理后，作为高端回用水回用于企业对水质要求更高的环节。实际运行数据表明，该工艺运行稳定，出水水质稳定达标，低端回用水系统直接运行成本（以进水量计）为3.2元/m3，高端回用水系统（UF+RO）直接运行成本（以产水量计）为1.1元/m3。
- Abstract:
- To address the issues of significant fluctuations in water quality and poor biodegradability of dyeing wastewater in a textile industrial park in Jiangsu Province, an integrated process of AO/MBR + ozone catalytic oxidation + biological aerated filter (BAF) was adopted to ensure effluent compliance with the first level A limit specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). The treated effluent is divided into two reuse streams: one is directly supplied as low-grade reclaimed water to park enterprises, while the other undergoes advanced treatment via ultrafiltration(UF) + reverse osmosis(RO) to produce high-grade reclaimed water for industrial processes with stricter water quality requirements. The actual operation results indicate that the process has operated stably, with the effluent consistently meeting the required standards. The direct operating cost based on influent volume of the low?grade water reuse system is 3.2 CNY/m3, while that based on product water volume of the high-grade water reuse system (UF + RO) is 1.1 CNY/m3.
