芜湖市Integrated Aquaculture Wastewater Treatment Equipment — Resolve Aquaculture Sewage Difficulties to Promote Standardized Green Breeding Development

    The integrated breeding sewage treatment equipment is an integrated purification system specially designed for high-concentration organic breeding wastewater. It integrates pretreatment, biochemical treatment, advanced purification, disinfection and other functional modules into one unit, efficiently removing pollutants including COD, ammonia nitrogen, total phosphorus, suspended solids and pathogens. The treated effluent complies with Discharge Standard of Pollutants for Livestock and Poultry Breeding (GB 18596-2001) and local environmental regulations. It can be directly discharged or reused for barn flushing, farmland irrigation and aquaculture water replenishment to realize water recycling.

    The equipment adopts a three-stage progressive treatment mode to target the characteristics of breeding wastewater: high organic concentration, high ammonia nitrogen, abundant suspended solids and fluctuating water quality.

    Mechanical bar screens, solid-liquid separators and regulating tanks intercept large impurities such as manure and feed residues, balance water quality and flow, reduce the load of subsequent treatment and improve overall system stability.

    Mature processes including A/O, A²/O and MBR membrane bioreactor are applied as core technologies. Through synergistic metabolism of anaerobic, anoxic and aerobic microorganisms, organic matter is degraded and nitrogen & phosphorus are removed efficiently. The ammonia nitrogen removal rate exceeds 90%, and COD removal consistently meets discharge standards.

    Sedimentation, filtration and UV/ozone disinfection further eliminate residual pollutants and harmful microbes. The final effluent is clear and odorless, satisfying reuse or discharge standards without secondary pollution throughout the process.

    Modular design supports above-ground or buried installation with no large-scale civil construction required, adapting to limited space on farms. It cuts land occupation by more than 50% compared with traditional processes.

    Optimized processes deliver strong anti-shock load capacity and stable continuous operation. Effluent indicators stay compliant long-term to easily pass environmental inspections and routine supervision.

    Equipped with a PLC automatic control system, it realizes fully automatic operation of liquid level adjustment, aeration, sludge discharge and backflow. No full-time professional operators are needed, cutting labor costs.

    High-efficiency aeration devices and energy-saving pump sets lower the cost per ton of treated water with less sludge output, reducing subsequent disposal expenses and fitting the profit characteristics of the breeding industry.

    Customized solutions are available according to breeding scale (5–500m³/d), water quality and site conditions, compatible with new farms and renovation of old facilities for rapid deployment.

    Fully enclosed structure prevents odor diffusion and sewage leakage, helping farms meet environmental policies and achieve sustainable development.

    The integrated breeding sewage treatment equipment fits all types of breeding scenarios:

    Livestock and Poultry Breeding: Large-scale pig, chicken, cattle, sheep and duck farms;

    Aquaculture: Industrial aquaculture, high-level ponds and pond tail water treatment;

    Agriculture-Animal Husbandry Complex: Planting-breeding integrated bases, breeding parks and sewage treatment supporting livestock & poultry slaughterhouses.

    Matching equipment models are available for small and medium scattered farms as well as ten-thousand-head large-scale breeding bases to quickly achieve standard sewage treatment.

    Select equipment models based on daily sewage output to avoid over-sizing or insufficient processing load and guarantee treatment efficiency.

    A/O+MBR combination is preferred for high ammonia nitrogen wastewater; contact oxidation process is a cost-effective option; advanced filtration modules are mandatory if water reuse is required.

    Carbon steel with anti-corrosion coating, stainless steel and fiberglass are mainstream materials, featuring corrosion resistance and long service life to adapt to humid and complex farm environments.

    Prioritize models with automatic operation, easy cleaning and simple maintenance to reduce daily operation difficulty and failure risks.

    Against the backdrop of stricter environmental policies and the universal consensus of green breeding, integrated breeding sewage treatment equipment has shifted from an optional accessory to essential infrastructure. It not only eliminates sewage pollution on farms, but also enables water recycling to cut water costs, improve brand image and compliance competitiveness, and drive the breeding industry toward ecological, standardized and intelligent transformation and upgrading.
