- 摘要:
- 介绍了靖江市电镀园区废水提标改造工程的处理工艺、主要构筑物参数及运行效果。在原有处理工艺的含镍废水处理末端增加芬顿氧化、电化学及树脂吸附，含铬废水处理末端增加焦亚还原、微电解及平板超滤膜。各类预处理单元混合后，生化处理增加“厌氧水解 - 两级 A/O+PACT-MBR ”工艺，另外采用臭氧、芬顿高级氧化及树脂吸附作为终端保障措施把关。提标改造后工艺运行平稳，自动化程度高，出水水质从原来的《电镀污染物排放标准》（ GB21900 — 2008 ）表 2 提升至表 3 特别排放限值，有效改善了周围的水环境，对同类型电镀园区污水处理厂的提标改造具有一定的参考意义优势。
- Abstract:
- ： This paper presents the treatment process ， main structure parameters and operation effect of the wastewater upgrading and reconstruction project in Jingjiang Electroplating zone.Fenton oxidation ， electrochemistry and resin adsorption were added at the end of the original nickel-containing wastewater treatment ， and pyrolytic reduction ， micro-electrolysis and flat ultrafiltration membranes were added at the end of the chromium-containing wastewater treatment. After these various pretreatment units were mixed ， the process of "anaerobic hydrolysis-two-stage A/O+PACT-MBR" was added for biochemical treatment. Furthermore ， to ensure the final effluent quality ， ozone ， advanced Fenton oxidation ， and resin adsorption were employed as additional safeguards. The upgraded process demonstrated stable operation and a high degree of automation. As a result ， the effluent quality was significantly improved ， surpassing the standards outlined in Table 2 of the "Discharge Standards for Electroplating Pollutants" （ GB21900 — 2008 ） and meeting the more stringent special discharge limits specified in Table 3. These improvements effectively enhance the surrounding water environment and serve as a valuable reference for similar upgraded wastewater treatment facilities in electroplating parks.
