Introduction
A waste treatment equipment plant integrates multiple treatment stages—physical, chemical, and biological—into a comprehensive system engineered to treat complex effluents from industrial and municipal sources. Hebei Huayu Environmental Engineering Co., Ltd delivers turnkey plants tailored to specific discharge standards or water-reuse objectives.
Process Flow
Influent Reception: A receiving chamber with coarse screening and flow measurement regulates incoming waste.
Pretreatment: Grit removal and oil–water separation protect downstream units.
Primary Clarification: Lamella settlers or circular clarifiers remove settleable solids, reducing suspended solids load by up to 70%.
Biological Treatment: Options include activated-sludge reactors, sequencing batch reactors (SBR), moving-bed biofilm reactors (MBBR), or membrane bioreactors (MBR), chosen according to required biochemical oxygen demand (BOD) and nutrient-removal targets.
Tertiary Polishing: Sand filters, ultrafiltration modules, or granular activated-carbon adsorbers eliminate residual suspended solids, colloids, and trace organics.
Disinfection: UV reactors or chlorination systems ensure pathogen reduction to meet public-health requirements.
Engineering and Controls
A centralized SCADA platform monitors pH, DO, turbidity, and flow in real time, adjusting aeration, mixing, and chemical dosing automatically. Redundant pumps and blowers maintain continuous operation during maintenance or equipment failure.
Structural Materials
Concrete, FRP, or coated-steel tanks are selected based on influent chemistry and local climate. Piping systems use PVC, HDPE, or stainless steel where abrasion or corrosive chemicals are present.
Sludge Management
Thickening units concentrate sludge streams, which are then dewatered by filter presses or centrifuges. The resulting cake can be sent for composting, land application, or safe disposal.
Commissioning and Support
Hebei Huayu’s project team handles everything from site assessment and detailed engineering to fabrication, installation, and operator training. After start-up, service agreements cover performance audits, spare-part provisioning, and remote diagnostics to maintain effluent-quality guarantees.
