Introduction
Hebei Huayu Environmental Engineering Co., Ltd designs and delivers turnkey industrial wastewater treatment plants tailored to treat effluents from sectors such as food processing, textile dyeing, electroplating, and chemical manufacturing. By combining physical, chemical, and biological unit processes, these plants achieve regulatory discharge limits and support water reuse objectives.
Process Train
Preliminary Treatment
Screening: Removal of rags, plastics, and large solids.
Grit Removal: Settling or cyclonic separation of sand and grit to protect downstream equipment.
Primary Treatment
Equalization Basin: Buffering flow and loading fluctuations; chemical dosing for pH adjustment.
Flocculation and Clarification: Coagulant and flocculant addition in mixing channels, followed by lamella or circular clarifiers to separate suspended solids.
Secondary Treatment
Biological Reactors: Options include aerobic activated-sludge, Moving Bed Biofilm Reactors (MBBR), or Membrane Bioreactors (MBR) selected based on effluent standards and footprint constraints.
Air Scour and Mixing: Fine-bubble aeration systems maintain dissolved-oxygen levels; mixers prevent dead zones.
Tertiary Treatment
Filtration: Sand, multi-media, or ultrafiltration to remove residual solids.
Advanced Oxidation: UV/H₂O₂ or ozone systems for organic-compound reduction when required.
Disinfection: UV irradiation or chlorination ensures microbiological safety.
Design Considerations
Flow Rate and Load: Plants are sized for average and peak flows, with bypass options for high-peak conditions.
Space Constraints: Modular, skid-mounted systems minimize civil-work and accelerate installation.
Automation: PLC/SCADA platforms control pumps, blowers, chemical dosing, and solids handling, while providing remote monitoring and alarms.
Construction Materials
Recoating and linings (epoxy, polyurethane) protect steel tanks and channels from corrosive influents. Piping employs PVC, PP, or stainless steel as appropriate. Select components (e.g., blower housings, mixer shafts) are made of corrosion-resistant alloys.
Sludge Management
Produced sludge is thickened using gravity thickeners or dissolved-air flotation units, then dewatered via filter presses or centrifuges for disposal or beneficial reuse.
Performance Guarantees
Hebei Huayu Environmental Engineering Co., Ltd provides contractual effluent-quality guarantees, supported by factory acceptance testing and pilot-plant trials when required.
Service and Support
From initial feasibility studies and process design to fabrication, installation, and operator training, each project includes comprehensive documentation and after-sales service agreements for preventive maintenance and performance optimization.
