Integrated sewage equipment usually includes multiple treatment units that work together to complete pretreatment, biological treatment and post-treatment of wastewater. The following are some common equipment treatment units:

       1, grille pretreatment unit: Grilles are usually used to remove large particulate matter in wastewater, such as solid waste, leaves and other impurities. This helps protect subsequent processing units from blockage or damage.

       2, Sand settling pretreatment unit: The sand settling tank or sand settler is used to remove fine particulate matter and gravel deposited in the wastewater to reduce the suspended solids content of the wastewater.

       3Adjustment pool: The adjustment pool is used to balance and stabilize the flow and load of wastewater to avoid excessive impact load on subsequent treatment units.

       4, bioreactor: Bioreactor is the core part ofintegrated sewage equipment, which includes various biological reaction units. These units remove organic matter from wastewater through the action of microorganisms.

       5, Sedimentation tank: The sedimentation tank is used to separate the sludge and wastewater in the bioreactor, so that part of the sludge can be returned to the bioreactor and discharge relatively clean wastewater.

       6, Adsorbent unit: These units are used to remove refractory substances through adsorption or adsorption.

       7, denitrification and dephosphorus units: These units are used to remove nitrogen and phosphorus from wastewater to reduce environmental pollution.

       8, Disinfection unit: The disinfection unit uses chemicals to kill or remove pathogens and microorganisms in wastewater to ensure that the discharged water quality meets sanitary standards.

       9, Air flotation unit: The air flotation unit injects air into the wastewater to separate suspended solids and buoyant bubbles, thereby reducing the solid and grease content in the wastewater.

       10, filter unit: The filter unit includes sand filter, carbon filter and other types of filter units, which are used to further remove particles and impurities in wastewater.

       These treatment units are usually combined in integrated sewage equipment in specific sequences and configurations to meet different wastewater treatment needs and discharge standards. The design and configuration of the equipment can be adapted to the specific application and treatment water quality requirements. The equipment usually has a compact structure and a small footprint, and is suitable for wastewater treatment in various locations.
