(57) Abstract:Usage: for treatment of sanitary wastewater from individual structures with a number of residents 6-10 people. Installation of small sewage contains steel tank with attached inlet and outlet piping. The tank is placed a removable basket with mesh bottom stainless steel. In the upper part of the tank has a pipe for natural ventilation. In the basket sequentially stacked one upon the other three filters in the form of nylon bags with activated charcoal, sawdust and quartz sand. Between the mesh bottom of the basket and the bottom of the tank there is a space in which going filtered waste water. These waters can be defined in an additional reservoir or lower through the drainage system in the reservoirs. 1 Il. The invention relates to cleaning devices used in low-drain, and can be used for treatment of sanitary wastewater from individual structures with a number of residents 6 to 10 persons.Known treatment unit for small sewage, using aerobic biological treatment, including aerosance  and cept is in the first case and a low degree of purification, great complexity when sediment removal in the case of septic tanks.The closest analogue of the claimed device is the installation of small sewage to remove any wastewater used for houses, occupied by one family 
The system includes a septic tank with inlet and outlet pipes, the coarse filter in the form of a removable basket with mesh bottom, natural ventilation.The disadvantages of the prototype are the design complexity, the need for removal of sludge from septic cavity, as well as special requirements for filtration materials, due to the need to maintain hydrostatic equilibrium in the system.The aim of the invention is to simplify the design of the device and reducing the complexity of the service.The invention consists in that the installation of small sewage containing reservoir located therein a removable basket with mesh bottom, inlet and outlet pipelines, natural ventilation, supplied sequentially stacked in the basket on one of the other filters in the form of nylon bags with activated charcoal, sawdust and quartz sand.In the drawing predstavljaet 2 and outlet 3 pipelines. In the tank 1 is placed a removable basket 4 with mesh bottom 5 of stainless steel. In the upper part of the tank has a pipe for natural ventilation 6. In the basket 4 stacked filters 7,8,9. The filter 7 is a nylon bag filled with activated carbon filter 8 nylon bag with sawdust, the filter 9 is a nylon bag with silica sand. Between mesh bottom 5 basket 4 and the bottom of the tank 1 there is a space in which going filtered waste water. These waters can be defined in an additional tank or to drain through the drainage system into the water.The device operates as follows. Through the supply line 2 sewage water enters the tank 1. The filter 9 from quartz sand delays of suspended inorganic and organic residues. The filter 8 from sawdust removes fat contamination. The filter 7 of activated charcoal absorbs colloidal organic and inorganic pollution.The wastewater that passed in the inventive cleaning device, the quality of match values for the reset in the fishery waters.The materials selected for filtering, can be subjected to incineration or to use after a year of composting as the A.1.
