    Equipment introduction:
    With the rapid development of animal husbandry in China, the pollution of aquaculture wastewater is increasing, and its pollution prevention and control is imminent. The aquaculture wastewater has the typical "three highs" characteristic, namely: CODcr is as high as 3000 ~ 12000mg / L, ammonia nitrogen is as high as 800 ~ 2200mg / L, and the SS exceeds the standard dozens of times. Limited to the small profit industry of the aquaculture industry, the treatment process only aims at the substantial reduction of CODcr, and there is still a great technical difficulty in meeting the ammonia nitrogen emission standards.
    The aquaculture wastewater treatment equipment is a treatment equipment that collects the daily sewage produced by the farm and passes it into the integrated equipment after several steps of processing. The materials of integrated sewage treatment equipment are usually carbon steel, stainless steel and glass steel, which can be customized according to the requirements of the owner. The integrated aquaculture wastewater treatment equipment is specially designed for the sewage of the aquaculture industry, and the treatment process is designed to treat it.

    Scope of application:
    Applicable to sewage produced by various livestock and poultry farms (chicken farm, duck farm, pig farm, cattle farm, rabbit farm, fox farm, etc.).

    Process characteristics:
    1. Advantages:
    Remove BOD before aerobic, save energy;
    Generate alkalinity before nitrification;
    Pre-hypoxia has the function of selecting the pool;
    The process is simple;
    Short hydraulic retention time;
    Good sludge sedimentation performance;
    Phosphorus accumulating bacteria have rich carbon sources and good phosphorus removal effect.
    2. Deficiencies:
    The nitrogen removal effect is affected by the internal circulation ratio;
    Possible problems with Nocardia;
    Need to control the DO of the circulating mixture;
    If nitrification occurs, the phosphorus removal effect will be reduced;
    Poor process flexibility.

    Equipment advantages:
    1. Integrated aquaculture sewage treatment equipment is composed of one or more units connected on site, which is small in size, light in weight, easy to transport and convenient to install;
    2. It adopts FRP, carbon steel, stainless steel anti-corrosion structure, which has excellent characteristics such as corrosion resistance and aging resistance, with a service life of more than 20 years;
    3. Save land, no need to build a house, heating and insulation. Maximize equipment integration and reduce floor space;
    4. No pollution, no odor, reduce secondary pollution,
    5. There is no restriction on the amount of sewage collected, and it is flexible and can be used individually or in combination.
    6. The entire processing equipment is equipped with an automatic control unit and a fault alarm device, which is safe and reliable in operation. Usually, no special person is required to manage it. It is only necessary to maintain and maintain the equipment in a timely manner with low management costs.
