Where is the septic tank at home? Where is the best place to dig a septic tank when building a house?
2. Many farmers have a yard in front and back, with flowers and plants in the front yard and fruits and vegetables in the back yard. At this time, we can use it to grow vegetables, fields and land, which not only saves chemical fertilizer, but also nourishes crops. Moreover, naturally fermented manure is much better than the current agricultural chemical fertilizer. Now the orchard advocates the use of farmyard manure, which can kill two birds with one stone. Secondly, compared with cities and towns, the population density in rural areas is not large. In terms of treatment, it is generally advocated to build biogas digesters and reuse wastes.
3. The biogas digester can produce a part of biogas through pressurized oxygen fermentation, and we can use it as gas to cook and boil water. Septic tanks can be built in the yard and then piped to the toilets in the house. Septic tanks are generally built in three compartments, and the melted sewage is discharged, and then a small manhole can be made to be discharged together with domestic sewage at ordinary times. In addition, it should be noted that it is best to discharge the bath water separately from the toilet sewage, because the bath water is generally large and it is easy to cause the septic tank to overflow.
