1. operation principle of concrete septic tank
the septic tank is generally planned as a three format septic tank. fresh feces enter the no.1 tank through the toilet pipe. the feces in the tank start to ferment and differentiate into biogas. due to different specific gravity, the feces can be divided into three layers. the upper layer is relatively thick fecal waste, the grass-roots layer is massive or granular fecal waste, and the middle layer is relatively clear fecal liquid. there are many bacteria and parasite eggs in the upper feces and the grass-roots fecal waste, and the middle layer is relatively clear there are less eggs, and the middle-level fecal liquid which starts to ferment flows to no. 2 tank through the fecal pipe. the second tank overflows to no. 3 tank after the differentiation and sedimentation of the re fermenting enzyme, and the no. 3 tank flows to the water pipe after the sedimentation and filtration.
