榨菜是重庆市特色优势农产品加工产业,在万州、涪陵等主产区形成了完整产业链。榨菜腌制加工过程中产生的废水盐分浓度高、处理难度大,传统处理工艺成本高、盐分难以资源化,含盐废水持续外排会给长江流域水环境带来压力。
重庆市生态环境局11日对外公布,由重庆市生态环境科学研究院自主研发的榨菜行业高盐废水关键处理技术取得阶段性成果,以该技术为核心的废水处理示范工程在万州区鱼泉榨菜公司顺利建成投用,为重庆市榨菜特色产业绿色转型找到新路径。
榨菜是重庆市特色优势农产品加工产业,在万州、涪陵等主产区形成了完整产业链。榨菜在腌制加工过程中产生的废水盐分浓度高、处理难度大,一直是制约行业绿色发展、影响流域水环境安全的突出痛点。传统处理工艺成本高、盐分难以资源化,含盐废水持续外排会给长江流域水环境带来压力,是行业长期面临的环保难题。
此次落地鱼泉榨菜的示范工程设计处理废水规模达48吨/天,处理盐度大于8%,年可处理榨菜高盐废水约1.5万吨,每年至少削减排盐量1200吨,从源头减少了高盐废水对周边水环境的冲击。同时,该示范工程产出结晶盐含水率控制在5%以内,收集贮存后可回用于次年榨菜腌制生产,打通“废盐—回用”闭环,实现盐资源循环利用,既节约企业腌制原料采购成本,又大幅减轻固废处置负担,真正实现环境效益、经济效益双赢。
重庆市生态环境科学研究院相关负责人介绍,这套技术针对性适配榨菜废水水质波动大、盐分高的行业特点,整套工艺路线成熟稳定,具备可复制、可推广的特点,为重庆市榨菜加工企业高盐废水治理提供了一体化解决方案,将有力推动榨菜行业污染精细化治理,助力特色食品产业绿色低碳、可持续发展。
下一步,重庆市生态环境科学研究院将持续做好示范工程跟踪服务,指导企业完善常态化运维管理机制,根据实际运行情况动态优化工艺参数,保障设施长期稳定运行。同时,系统梳理工程实践数据,提炼标准化技术方案和运维管理经验,逐步在全市榨菜加工产区推广应用,以生态环境科技创新赋能特色产业高质量发展。

Twenty-seven rare and rare winter migratory birds, cygnets, flew to the mouth of Lanyang Xikou in Yilan County to gather together, possibly setting a new record for the number of flocks coming to Taiwan. They then flew to Sanxing, Yuanshan and other places in batches. Bird enthusiasts started a craze for bird photography. The Bird Conservation Association called on people to watch from a distance without disturbing them.

The international plant taxonomy journal "Phytotaxa" published a new species of Aristolochia from the Minjiang River in Fujian. There are only 50 to 100 adult plants in the wild, and it is initially assessed as an endangered species. This is the second new plant species discovered in the Minjiangyuan Nature Reserve in a short period of time, confirming its excellent ecological background and complete forest ecosystem.
