Underground sewage treatment equipment has a high degree of automation, easy operation, simple management, and long service life. The forced water distribution and water inlet and outlet of the equipment are all static. Since the disturbance to the floc in the water is reduced to a small level, the scum is instantly removed, so the stability is high.
       Dosing system:
       Close the water inlet valve, open the chemical dosing port, add a small amount of quantitative medicine, and fasten the dosing cap; gradually open the water inlet valve, and control the amount of medicine added according to the sewage flow rate; before each addition of medicine, open the inlet and outlet water and flush them to avoid clogging; for residual chlorine detection, monitor the residual chlorine in the factory water the next day, gradually adjust the flow rate according to the size, and detect the residual chlorine at the end of the pipe network three days later.
       The self-priming pump is controlled by the liquid in the water collection tank. When the underground sewage treatment equipment is operating normally, the filter valve is adjusted to the operating state. When the water begins to become turbid after 3 to 4 days of operation, the filter valve is adjusted to the backwash state and backwashed with an external water source for 2 minutes. If the backwash water becomes clear, the backwash can be stopped.
       The above is the application of underground sewage treatment equipment dosing system.
