LD Household Septic Tank
A covered household septic tank is a type of domestic sewage pretreatment equipment, mainly used for anaerobic?digestion of domestic sewage, decomposing large molecular organic matter into small molecules and reducing the?concentration of solid organic matter. At the same time, small molecules and substrates are converted into biogas?(mainly composed of CH4 and CO2) by hydrogen producing acetic acid bacteria and methane producing bacteria.?Nitrogen and phosphorus components remain in the biogas slurry as nutrients for later resource utilization. Long term?retention can achieve anaerobic sterilization.
