The container contains anoxic, aerobic (containing MBBR filler), sedimentation, filter cloth filter filtration, disinfection (slow-release chlorine tablets or ultraviolet equipment), and equipment room process sections. The pretreated rural sewage first enters the anoxic zone through the water pump for denitrification reaction, and then passes through the aerobic zone for nitrification reaction to remove COD, BOD, ammonia nitrogen, TN, etc. in the water. The effluent from the biochemical zone enters the sedimentation zone (there is a coagulation reaction zone in front of the sedimentation zone for dosing and phosphorus removal) for mud and water separation, and then passes through the filter cloth filter to further remove SS in the water. After being disinfected by the disinfection equipment, it is discharged up to the standard, and the effluent water quality reaches the discharge standard.
       Standardized products in the form of integrated containers have the following characteristics:
       A． The biochemical zone is a mud film mixing process of activated sludge + biofilm: it can effectively increase the sludge concentration and reduce the equipment volume; it can well cope with the fluctuation of rural sewage water volume by increasing the filler filling rate;
       B. The anoxic zone of this product uses gas intermittent stirring, and the sludge and nitrification liquid return flow uses gas lifting. At the same time, the monitoring and oxygen release devices are cleverly designed to ensure the operation effect. Compared with conventional sewage treatment equipment, it saves submersible mixers, sludge return pumps, and nitrification liquid return pump equipment, saving investment costs, and has low operating energy consumption and low operating costs;
       C. This product uses our company's small filter cloth filter equipment, which is used as a depth filtration equipment and has many advantages such as small footprint, low energy consumption, stable operation, and easy operation;
       D. This product effectively integrates biochemistry, precipitation, filtration, disinfection and equipment rooms into standardized containers, reducing the project area and saving project civil construction costs; using this product, there is no need to build additional civil construction dosing rooms and equipment rooms, saving civil construction investment costs and alleviating the financial constraints of rural sewage projects.
       E． The overall dimensions of the product are consistent with the container, which is convenient for transportation and can be flexibly combined according to the water volume; currently, 30t, 50t, 80t, 100t, etc. can be flexibly matched.
