摘要
为解决AO(厌氧+好氧)工艺处理卡拉胶废水难达标的问题,针对卡拉胶生产过程中产生大量含藻类颗粒的废液富含盐碱和有机物的特点,采用混凝沉淀去除富盐碱的混合溶液,然后用厌氧、好氧生化处理工艺+芬顿反应池处理去盐碱的有机废液.经过一年期的运行结果表明:该工艺的最终出水pH值都落在6-9、色度为15-20度、CODcr、排放质量浓度为55-68 mg/L,出水质量达到《中华人民共和国污水综合排放标准》(GB8978-1996)一级排放标准.该工艺的整体效果好,可为卡拉胶生产企业提供参考借鉴.
Abstract
To address the challenges associated with treating carrageenan wastewater using the AO(anaero-bic+aerobic)process,this study employed coagulant sedimentation to effectively remove saline-rich mixed solutions.Subsequently,an anaerobic and aerobic biochemical treatment process,combined with a Fenton reac-tion,was utilized to decompose organic matter.After one year of operation,the results indicated that the final effluent pH ranged from 6 to 9,with a chroma of 15 to 20 degrees.The CODcr concentration was measured at 55 to 68 mg/L,demonstrating that the effluent quality met the first-level emission standards outlined in the People's Republic of China Comprehensive Sewage Discharge Standard(GB8978-1996).These findings sug-gest that the proposed treatment process is highly effective for carrageenan wastewater,providing valuable insights for carrageenan production enterprises.
