Abstract

FIELD: sewage system, particularly combination of engineering structures and sanitary procedures for collection and draining-off domestic sewage water concerned with day-to-day people activity in countryside.

SUBSTANCE: sewage system includes bath, lavatory pan, washing stand, collecting vessel and decomposition vessel with orifices for purified water discharge in ground. Gas relief valve and pipeline are arranged in upper part of decomposition vessel. Above vessels are made as metal drums. Located inside decomposition vessel is filter system. Orifices are drilled in lower part of decomposition vessel and arranged along the full vessel bottom perimeter. Fertilizers from decomposition vessel are removed through above valve. System has connection means formed as flexible couplers to link domestic sewage junctions with above system structures.

EFFECT: increased operational reliability, simplified structure, technology and maintenance, reduced cost.

Description

The invention relates to sewerage, and in particular to a complex of engineering structures and sanitary measures that ensure the collection and disposal of domestic wastewater associated with everyday human activities in rural areas.

A device is known, which is a toilet bowl, inside which the waste is processed into compost (Razumovsky E.S. Wastewater treatment and disinfection of small settlements, 2nd ed. - M .: Stroyizdat, 1986, 106 pp.). Compost is used as fertilizer. The dry closet is intended for use by one family. However, the use of the dry closet does not solve the issue of wastewater treatment from other sanitary devices (washbasins, bathtubs, sinks, etc.)

The closest solution to the technical problem to the claimed invention is a simple device in which wastewater from the toilet, sinks and bathtubs is piped into a pit (septic tank) where biological treatment of wastewater by anaerobic digestion is carried out - an autonomous sewage system including a bathtub, toilet bowl, washbasin, accumulation capacity, splitting capacity with an opening for the removal of purified water into the soil, in the upper part of which a gas discharge valve is installed, and pipelines (Rudolf Randolph. What to do with waste water waters. 2-nd ed. - M .: Stroyizdat, 1987, p. 34-36). Such a septic tank allows you to achieve effective treatment even with negligible care, since the amount of wastewater generated in an individual building is small compared to the total amount of wastewater of the village.

The disadvantage of this device is the large size of the pit, where the fermentation process is carried out naturally for several months, as well as the shape of the septic tank - rectangular, made of brick. Despite the fact that the rectangular septic tank has a simple design, a sufficient amount of building materials is spent on its device, construction costs increase.

The present invention solves the problem of the so-called "convenience in the yard", creates the usual hygienic and comfortable amenities of the toilet room of a city apartment in rural areas. The invention greatly simplifies the process of collecting, draining and processing domestic wastewater from everyday human activities.

Autonomous sewage system (hereinafter system) has:

- simplicity of design, allowing the use of factory manufacturing and installation on site in a short time with a minimum amount of construction work,

- high reliability, provided by low throughput, uncomplicated technical schemes, the use of devices, mechanisms and apparatuses with a very small percentage of failure,

- a simplified technology based on public biochemical processes of the human body, which allows not to upset the ecological balance of the environment,

- ease of operation, since it does not require additional maintenance efforts, except for the need to remove the finished fertilizer,

- low cost.

The technical result is achieved by the fact that in an autonomous sewage system including a bathtub, toilet bowl, washbasin, storage tank, splitting tank with a hole for draining purified water into the ground, a gas discharge valve is installed in the upper part, and pipelines, these containers are made in the form of metal barrels, a filter system is placed inside the specified splitting tank, the indicated holes are drilled along the bottom of this tank along the entire length of the bottom. Through this valve, fertilizers are manually removed from the cleavage tank. The system has connecting devices made in the form of flexible couplings, with the help of which the sewerage decoupling in the house is docked with the system structures.

The drawing shows a General diagram of an autonomous sewage system.

The autonomous sewage system contains a bath 1, a toilet 2, a washbasin 3, storage tanks 4 made in the form of metal barrels and a splitting tank 5 with openings 6 for removing purified water to the ground and a gas discharge valve 7 installed in the upper part, connecting devices 8 made in the form of flexible couplings, and pipelines 9.

Inside the splitting tank 5, a filter system 10 is placed, and holes 6 are drilled along the entire length of the bottom of the bottom 6. Using the connecting devices 8, made in the form of flexible couplings, the sewage system in the house 11 is decoupled with the system structures, which makes it possible to eliminate violation of the system tightness throughout the installation scheme, which has different dynamics parameters (twisting effect) than the capital structure (house, cottage, farm, barracks, etc.). Waste collection is carried out under the foundation level 12 of the house 11.

The system works as follows: wastewater generated from everyday human activities (metabolic processes in the human body, washing dishes, food, etc.), from the toilet 2, bath 1 and wash basin 3 through pipelines 9 is discharged into storage tank 4, where it is divided into different fractions by specific gravity, retaining the acid component of urine and heavy organics. An acid solution is gradually formed in the storage tank 4, the concentration of which increases.

The solution does not freeze, organics react with acids and burn out. Excess water and floating organics enter the cleavage tank 5, where due to the almost absence of oxygen, even the most dangerous wire formations of bacteria are disinfected and destroyed. The released hydrogen sulfide heats all the cavities of the system. Through a system of filters 10 made of inert building materials and placed in a splitting tank 5, filtered and disinfected water is drilled through the drilled holes 6 in the bottom into the soil 13. When the fertilizer reaches the critical level and, as it is ready, the fertilizer is manually removed from the tank 5 splitting through the gas discharge valve 7, pre-bleeding the gas.
