Currently, autonomous sewage system for a cottage is a long -familiar phenomenon, which is considered not just an indicator of comfort, but a necessary engineering system, the installation of which is implied by default.
Methods of cleaning the wastewater of the cottage
waste disposal and their transfer to the central trunk line;
Using local sewage. In this case, disposal and neutralization of waste will be carried out without a centralized withdrawal.
Of course, you can equip a simple cesspool, but this technology has a number of significant drawbacks. So, an unpleasant odor spreads from the pit, a biochemical pollution of the site occurs, it cannot be used simultaneously with a well or well, as well as low system performance.
In this regard, autonomous sewers and wastewater treatment systems are becoming increasingly popular. So, one of the most optimal options is considered septic tanks for cottages, the principle of operation of which is the possibility of sewage filtration.
How a septic tank for a cottage works
The septic tank guarantees the receipt after cleaning rather pure water, but it does not allow to produce its free release. It should also be borne in mind that the installation of such a system is usually possible only on soils with a deep occurrence of groundwater.
There is the possibility of installing an air tank on the septic tank and a special biofilter, as a result of which the possibility of dropping purified water into water bodies is achieved. The principle of operation of this system is that T. n. anaerobic stabilization, t. e. air supply is stopped and, accordingly, conditions for fermentation are created.
Next, the decomposition of the fat components occurs and a layer of precipitation and film is formed, the removal of which is carried out using the assigned machine. After that, water enters Aerotank, where it is mixed with active silt and forced purging oxygen is carried out. This allows you to achieve the effect of quick oxidation of all precipitation and their decomposition. And biofilters remove the last traces of pollution.
Typically, the septic tank has a sectional device, while in each section its own certain level of cleaning is achieved. So, in the first section there is a settling of severe precipitation and lifting up light impurities. The middle layer, where relatively clean water forms, falls into the next section. Depending on the number of such sections, the degree of water purification is determined, as well as its maximum load.
Further, purified water enters a specially equipped soil layer, in which it is cleaned with natural drainage, for which it is recommended to use a sand-gravel layer.
Advantages and disadvantages of septic tanks
The advantages of septic tanks include a fairly simple system of device and installation, the lack of unpleasant odors and the biochemical safety of the site. However, there is a certain drawback, which is manifested in the fact that waste from the system is not excreted, respectively, the septic tank requires regular maintenance.
As a private, it is necessary to clean the septic tank
Usually the septic tank is cleaned once every few years. This circumstance depends on the number of people living in the house. In addition to removing waste, cleaning includes partial replacement of the soil in those places where water directly enters the soil.
