从方案设计、材料加工、箱体制造、内部装配、MBR膜组件、电控测试到出厂检验，介绍一体化设备的生产过程。

生产从技术设计开始

一体化污水处理设备不是先制造箱体再选择工艺。生产前需要完成水量水质确认、工艺计算、设备分区、总图布置、管路仪表和电气控制设计。设计人员要把停留时间、曝气量、回流、膜面积和污泥处理等参数转化为可制造图纸，同时核对运输尺寸、吊装重量、管口方向、基础荷载和检修空间。只有设计文件经过确认，生产、采购和质量检验才有统一依据。

碳钢箱体制造与防腐

碳钢一体化设备通常经过钢板下料、成型、组对、焊接、加强结构安装、焊缝处理和表面防腐。生产重点包括尺寸精度、结构强度、焊缝连续性和防腐完整性。内部隔板与外部加强筋要与水压、吊装和运输条件相匹配。焊接完成后，应清理焊渣、飞溅和油污，按设计完成表面处理与涂装。后续管路和构件安装要避免破坏已完成涂层，划伤位置及时修补。

PP设备依靠挤出焊和加强

PP一体化设备可用于部分腐蚀性水质，生产包括板材下料、拼装、热风或挤出焊、加强筋和内部构件安装。焊接温度、速度、焊缝连续性和板材清洁度都会影响质量。PP的弹性模量和长期蠕变特性与钢材不同，因此大型设备需要合理的加强结构和支撑间距，并结合水温、液位和运输方式校核。中侨启迪具备PP设备生产线，可根据项目选择合适的材料与结构形式。

内部管路与功能部件装配

箱体完成后，需要安装曝气管、回流管、排泥管、膜抽吸管、阀门、泵、风机、填料或载体拦截装置。管路布置既要满足工艺流量，也要便于排空、拆卸和维护。曝气器应均匀布置，避免生化池出现死区；回流和排泥口要防止堵塞；设备外部的法兰和电缆接口应与现场图纸一致。装配完成后可进行管路试漏、转动设备方向检查和阀门标识核对。

MBR膜组件与电控生产

中侨启迪拥有自主MBR膜组件生产线，可将膜组件尺寸、膜面积、安装框架、曝气冲刷和抽吸管路与一体化设备同步设计。膜组件生产和安装需检查外观、连接密封、完整性和维护空间。电控柜则按照电气图完成元器件安装、线号、端子、接地和程序下载，并进行通电与I/O检查。人机界面应显示设备状态、手自动模式、参数和报警，远程功能根据项目网络条件配置。

出厂检验与资料交付

出厂前应核对设备编号、外形尺寸、材料、防腐、焊缝、管路、阀门方向、电控、铭牌和安全标识。根据合同可进行清水试漏、单机运行、控制联动或客户见证。照片、材料清单、检验表、合格文件、装箱单、英文操作手册和图纸应与设备对应。ZhongQiao Enlightenment拥有两个生产基地，总面积4万余平方米，年产设备800余台，规模化制造与非标设计相结合，可支持不同一体化污水处理设备项目的生产交付。

INTEGRATED WASTEWATER TREATMENT | ZHONGQIAO ENLIGHTENMENT

Production Process of Export Integrated Wastewater Treatment Equipment

From process engineering and material fabrication to tank assembly, MBR membranes, controls, and inspection, this article explains the production of integrated wastewater treatment equipment.

Production begins with engineering

Integrated wastewater treatment equipment is not a tank fabricated before the process is selected. Production begins with confirmation of flow and wastewater, process calculations, tank zoning, general arrangement, piping and instrumentation, and electrical controls. Retention time, aeration, recirculation, membrane area, and sludge handling must become manufacturable drawings. Transport dimensions, lifting weight, nozzle orientation, foundation loads, and maintenance access are checked before approved documents guide fabrication, purchasing, and inspection.

Carbon-steel fabrication and coating

Carbon-steel equipment is produced through plate cutting, forming, fit-up, welding, reinforcement installation, weld finishing, and corrosion protection. Key controls include dimensions, structural strength, weld continuity, and coating integrity. Internal partitions and external reinforcement should suit water pressure, lifting, and transport. Slag, spatter, and oil are removed before the specified surface preparation and coating. Later piping and component work should protect the finished coating, with any damaged area repaired promptly.

PP fabrication uses extrusion welding and reinforcement

PP integrated equipment can serve selected corrosive wastewater. Production includes sheet cutting, assembly, hot-gas or extrusion welding, reinforcement, and internal components. Temperature, travel speed, seam continuity, and sheet cleanliness affect weld quality. Because PP has different stiffness and long-term creep behavior from steel, large units require suitable reinforcement and support spacing based on water temperature, level, and transport. ZhongQiao Enlightenment operates PP production lines and can select the material and structure for project conditions.

Internal piping and functional components

After tank fabrication, the unit receives aeration, recirculation, sludge, membrane-suction, and other piping together with valves, pumps, blowers, media, and carrier-retention screens. Piping must meet process flow while allowing drainage, removal, and service. Diffusers should distribute air evenly to avoid dead zones. Recirculation and sludge points should resist blockage. External flanges and cable interfaces must match site drawings. Leak checks, rotation checks, and valve-label verification follow assembly.

MBR membrane and control-panel production

ZhongQiao Enlightenment operates an in-house MBR membrane production line, enabling membrane dimensions, area, frames, scouring air, and suction piping to be coordinated with the integrated unit. Appearance, connection sealing, integrity, and service access are checked during module production and installation. Control panels follow approved electrical drawings for components, wire numbers, terminals, grounding, and software. Energization and I/O checks confirm HMI status, manual and automatic modes, parameters, alarms, and project-specific remote functions.

Factory inspection and documentation

Before shipment, inspection covers identification, dimensions, materials, coating, welds, piping, valve direction, controls, nameplates, and safety labels. Contract requirements may include clean-water leak testing, individual equipment operation, control sequencing, or customer witness. Photographs, bills of materials, inspection forms, certificates, packing lists, English manuals, and drawings should correspond to each unit. ZhongQiao Enlightenment reports two production bases exceeding 40,000 square meters and annual output of more than 800 units, combining scaled production with project-specific design.
