The flow principle of integrated sewage treatment equipment: sewage flows into the solid-liquid separation chamber, and the solids in the water are separated and stored; the intermediate water between the upper scum and the solids at the bottom of the solid-liquid separation chamber is forced to overflow to the anoxic filter bed equipped with fillers to remove solids and organic matter. The decomposition of wastewater and the denitrification of nitric acid and nitrite; then it flows into the carrier flow chamber. Under the action of a large number of biofilms on the surface of the carrier filled with several millimeters to several centimeters, the organic matter in the sewage is further decomposed to nitrification, and the nitrification liquid returns to the solid-liquid separation chamber.

       The wastewater treatment water flows into the biological filtration chamber through a grating at the transfer part to prevent carrier loss. It is filtered from top to bottom through the carriers accumulated at the bottom to removeSSsuspended solids. The backwashing of the biological filter chamber is automatically completed twice a day by a small blower (2unit combination or1unit with dual outlets for air diffusion and backwashing). The rinsed backwash water containing suspended solids is returned to the solid-liquid separation chamber through the air stripping device.Integrated sewage treatment equipmentThe effluent at the bottom of the biological filter chamber is sent to the disinfection chamber through the metering device through the steam stripping method for disinfection and then discharged. The remaining treated water flows back to the carrier flow chamber through the side outlet of the metering box.

       The upper part of the solid-liquid separation chamber, anoxic filter bed and carrier flow chamber is equipped with a large-capacity inflow sewage storage space, that is, a flow adjustment part, which serves to buffer the peak flow when the flow is too large and cannot be processed temporarily. When there is no water inflow, the water level in the tank drops to a low level, and the incoming water from the biological filtration chamber circulates back through the metering box without being discharged; when there is water inflow, the water level in the tank rises, and the incoming water from the biological filtration chamber is metered, disinfected, and discharged through the metering box, and the remaining water circulates back to the carrier flow chamber.

       The entire system of wastewater treatment equipment is composed ofPCL操控，然后能够到达自动化的处置，也可减轻水到高峰期和低谷期的正常处置。Integrated sewage treatment equipment的特色：整套设备可埋入地下，不占土地面积；上面还可美化。净化程度高，整套体系污泥发生少； High degree of automation, low energy consumption, and easy installation. The generated noise is low, the odor is small, and the impact on the surrounding environment is small.
