Not all cottages and cottage villages have a central drain.In this case the question of drainage and wastewater treatment every home owner should decide.

methods of organization of the local sewage


private home owner can choose one of the following types of facilities for wastewater treatment:
- sinkhole;
- storage tank;
- septic tank with mechanical cleaning;
- local treatment plant.

This local treatment plants to date - the most modern form of an autonomous sewer for a country house, as they provide very good level of wastewater treatment by mechanical and biological methods. after local water treatment plants can be discharged into water bodies and used for watering the garden plot.

device Autonomous sewerage Autonomous


domestic sewage consists of:
- domestic sewage networks;
- outdoor sewerage networks;
- treatment plant;
- filtration fields (using septic tanks).

Network include domestic sewage system and water intake pipes that are inside the house.Receiving waters - all devices that use water: sinks, toilets, bathtubs, washing machines, etc.

Net external sewage - is a pipe through which water flows from the house to the sewage treatment plant.As the treatment plants is mainly used multi-chamber septic tank or sewage treatment plant, as these methods are the most convenient and suitable for use in the permanent residence of people in the house.If you have a septic tank, local drainage must be complemented by filtration fields, as they are required for purification of waste water from septic tanks.

The principle of local treatment facilities


Domestic wastewater are composed mainly organic contamination.Local stations for wastewater implement mechanical and biological treatment methods.Thus there is a biochemical degradation of organic contaminants by aerobic microorganisms.

To speed up the process of fine-bubble aeration is used, that is, an artificial air supply, due to which there is an additional oxidation of contaminants.As a result, waste water does not rot, become transparent, purified from bacterial and organic contamination. activated sludge, a residual product of wastewater treatment can be used to fertilize non-bearing plants.

Wastewater first enters the tank, where the preliminary biological treatment, and then uniformly injected into the aeration tank where air is supplied.There is an additional oxidation and final removal of organic contaminants to form activated sludge - waste product of aerobic bacteria coming from the water and air.Thereafter, water is supplied in a special tank, where the mechanical settling of the activated sludge.
