Rural sewage treatment equipment treats the water flowing into the biological filtration chamber through the flow bar to prevent damage to the carrier

In the upper part of the solid-liquid separation room of rural sewage treatment equipment , the anoxic filter bed and the current-carrying chamber are provided with a large-capacity inflow sewage storage space, that is, a flow adjustment unit, which is used to relieve the excessive flow at the peak flow rate and cannot be processed simultaneously. When no water flows in, the water level in the water tank drops to a low water level, and the water in the biological filter chamber is not discharged through the metering water tank; when water flows in, the water level in the water tank rises, and the water in the biological filter chamber passes the metering tank. Meter, sterilize the discharge and recycle the remaining water back to the carrier flow chamber.
The rural sewage treatment equipment treats the water flowing into the biological filtration chamber through the flow bar at the moving part to prevent the loss of the carrier, and filters the SS suspension from the top to the bottom by the carrier stacked on the bottom. The backwash of the biological filter chamber is performed automatically twice a day by a small blower (two or one set with two outlets for diffusion and backwash). The washed backwash liquid containing suspended matter is returned to the solid-liquid separation chamber through a stripping device. The effluent from the bottom of the biological filtration chamber is discharged into the sterilization chamber for disinfection by a metering device through a stripping method. The remaining treated water is returned to the carrier flow chamber through the side outlet of the metering tank.
For the design scale and design water quality of rural sewage treatment equipment, field surveys should be conducted as much as possible. For the domestic urbanization process, the township sewage treatment construction should be built in the short and long term first; the location of the village sewage treatment plant is easy. Try to avoid the problem of pollutant deposition caused by long-distance water transport.
For low-concentration water inflows, the village wastewater treatment process should choose a biofilm process that is more suitable for low-concentration wastewater treatment. Key equipment for sewage treatment, such as pumps and fans, is easy to set up for inverters. When the actual processing flow is low, the flow is adjusted by adjusting the motor speed to reduce power. Anti-specific system rural sewage treatment equipment has been in inefficient areas for a long time, causing energy waste. Village and town sewage treatment projects have been completed to avoid low-load operation. The sludge load should be adjusted according to the actual water inflow during operation.
Rural sewage treatment equipment is controlled by PCL and can then be processed automatically, which also reduces normal water treatment to peak and trough periods. Features of rural sewage treatment equipment: The entire set of equipment can be buried underground without occupying land area; it can beautify. High degree of purification, less sludge in the whole system; high degree of automation, low energy consumption, convenient operation, and fewer personnel. The noise produced is low, the smell is small, and the impact on the surrounding environment is small.
