生活污水处理一体化装置
一种同时反硝化脱氮除磷双污泥污水处理系统。主体设备设厌缺交替区、气提区、好氧硝化区、沉淀区四个单元。通过厌、缺氧交替环境核心技术培养反硝化聚磷菌(denitrifying phosphorus removing bacteria, 简称 DPB),其在缺氧的条件下以硝酸盐代替氧为电子受体,同步完成反硝化脱氮和过量吸磷过程。通过固定膜核心技术在不同的反应单元内分别固定DPB、PAO 、AOB等微生物,创造各自最适宜生存环境。本专利设备具有突出技术优势,适用于多种低C/N污水处理场景,包括河流湖泊、大多数城镇生活污水等。处理效果稳定,运行可靠,满足《城镇污水处理厂污染物排放标准》(GB18918-2002)一级A标准。
环境综合治理服务系统
环境综合治理服务系统包括装配式污水处理厂站、分散式一体化设备、工业水处理与零排放技术、医疗废水无害化处理、河流综合治理与生态修复、土壤修复治理技术与环保管家综合服务系统,覆盖水环境全生态链,打造综合性、可靠性、稳定性的环境综合治理服务系统。

装配式污水处理厂
东日环保装配式污水处理厂,外形采用圆形或方形结构设计,内部高度集成了缺氧好氧沉淀等污水处理单元,采用工厂标准模块化预制结合现场拼接组装的方式实现污水处理厂站的快速高标准构建。该类型污水处理厂还通过内部结构创新,仅通过曝气即可形成固液气三相内循环和沉淀分离,能耗、占地和处理效率均较传统活性污泥工艺有明显提高,与传统污水处理厂相比,具有吨水能耗节省10%,投资成本节省20%,占地面积节省30%,建设周期节省40%的优势。
