摘要
黄江镇双渠污水处理工程采用化学絮凝-氧化组合工艺技术,针对该地区高浓度复杂污水进行处理。进水水质复杂多样,COD峰值达182 mg/L,氨氮质量浓度峰值213 mg/L,总磷质量浓度峰值3.8 mg/L,同时存在铬离子和镉离子等重金属污染,细菌总数高达14000 MPN/mL。工程于2024年7月投入运行,通过7-12月连续监测数据分析表明,化学絮凝工艺在悬浮物、胶体污染物和重金属去除方面表现优异,氧化工艺在有机物降解和深度净化效果显著。组合工艺协同作用下,COD去除率稳定在86%~89%,氨氮去除率达82%~88%,总磷去除率达92%~96%,重金属离子去除率超过90%,细菌总数削减率达95%~97%,出水水质全面达到排放标准要求。该工艺技术路线为类似高浓度复杂污水处理工程提供了重要的技术参考和实践经验。
The Shuangqu sewage treatment project in Huangjiang Town adopts a chemical flocculation oxidation combination process technology to treat high concentration and complex sewage in the area.The inflow water quality is complex and diverse,with a peak COD concentration of 182 mg/L,a peak ammonia nitrogen concentration of 213 mg/L,and a peak total phosphorus concentration of 3.8 mg/L.There is also heavy metal pollution such as chromium and cadmium ions,and the total number of bacteria is as high as 14000 MPN/mL.The project was put into operation in July 2024.Through continuous monitoring data analysis from July to December,it was shown that the chemical flocculation process performed excellently in the removal of suspended solids,colloidal pollutants,and heavy metals,while the oxidation process showed significant effects in organic matter degradation and deep purification.Under the synergistic effect of the combined process,the COD removal rate remains stable at 86%~89%,the ammonia nitrogen removal rate reaches 82%~88%,the total phosphorus removal rate reaches 92%~96%,the heavy metal ion removal rate exceeds 90%,the total bacterial reduction rate reaches 95%~97%,and the effluent quality fully meets the discharge standard requirements.This process technology route provides important technical references and practical experience for similar high concentration complex sewage treatment projects.
