[0002] A septic tank is a device that treats feces and filters and precipitates it. The principle is that the solidified matter decomposes at the bottom of the tank, and the hydrated matter on the upper layer flows into the pipe, preventing the pipe from being blocked and giving the solidified matter (feces and other garbage) sufficient time to hydrolyze. A septic tank refers to a small treatment structure that separates and precipitates domestic sewage and performs anaerobically digested sludge.
