I WILL INSTALL FOR CLEANING THE ECONOMY

The utility model relates to the field of construction of sewage facilities, and more specifically to devices, it allows the separation of liquid or solid substances from wastewater and can be used to treat household wastewater in houses that do not have a centralized sewage system.

Known sewer structures, called seitikamzh, containing at least two chambers separated by a partition with a number of holes in the middle part and inlet and outlet pipes. In such structures, which are cylindrical wells with a cover, the dividing wall is slightly higher than the level of wastewater (see, for example, the book by I. Gruller, Sewage treatment plants, small sewage system, Moscow, Stroyizdat, 1980, p. 37-41). In these installations, the settling ingredients of the wastewater sink to the bottom of the sentic, and thus the wastewater is purified from the siege in it.

However, the fermentation gases formed during the rotting process in greater or lesser quantity are entrained by the flow of wastewater moving above the sediment, and therefore the effluent that flows out becomes a putrefactive odor. In addition, simple in construction dangshe buildings are inefficient.

Sewer constructions are also known, which are a sealed three-chamber structure made of monolithic or prefabricated concrete with hydraulic locks, a ventilation device, an inlet and outlet pipe (see I. Rruler's book Sewage Treatment Plants, Moscow, Stroyizdat, 1980, 0.42-44, Fig. .17).

The above device is closest in technical essence and the number of common features to the claimed utility model, which is why we are taken as a prototype.

However, the above installation is also inefficient

and in it there is only mechanical b-b-b, without biological, which makes it necessary to provide further protection against the emission of gases with an unpleasant odor into the external environment. This facility, even with regular removal of sludge produced once or twice a year, gives the maximum cleaning effect for suspended solids of 70-75 and for EPK (biological oxygen demand) is only 30-35.

The problem to which the claimed technical solution is directed is to increase the efficiency of cleaning, while simplifying the maintenance; and without: used1;: cesspool and electric drive devices.

The technical result from the use of the proposed installation is that it, working by gravity and in self-regulating mode, allows you to achieve 90 capture pollution by suspension and BZ.

The above technical result is achieved due to the fact that in the installation for the treatment of domestic wastewater containing a sectional container with hydraulic locks, ventilation

the device and the inlet and outlet pipe, in the common case there is a methantank and a drop biofilter separated by a heat-conducting wall. The installation is equipped with a heating jacket, and a slot labyrinth is installed at the bottom of the drop biofilter in front of the outlet pipe.

Various techniques are known in the art for individual (autonomous) drip biofilters and methane tanks, as well as combining them when working in a common system. However, for the operation of such systems, mechanical devices and pumps driven by electric or other engines are necessary, which greatly complicates and increases the cost of their manufacture and maintenance. % ome that for normal operation of the biofilter it is required to maintain the optimum temperature regime in it.

The proposed installation allows to achieve the above technical effect without pumps, heating and drive mechanisms. This is due to the combination of a drip biofilter and a methane tank in a common casing, which are separated by a heat-conducting partition in the upper part, as well. . .- ::. the use of all of these features, interconnected with the formation of a set of essential features, sufficient to obtain the desired technical result.

The utility model is illustrated in the drawing, which shows a cross section of a plant for the treatment of domestic wastewater.

The installation consists of a complete body I, divided by a sealed heat-conducting wall 2 and a partition 3 into sections 4, 5 and 6, which form a drip, respectively

biofilter and methantank. Holes are made in a vertical partition 3 not reaching the ceiling, in its middle part 7. An inlet pipe is installed at the entrance to the methane tank section 4 8. A slot labyrinth 9 is located at the bottom of the biofilter at the bottom of the biofilter 9, and a ventilation duct is installed at the top of the section pipe 10. Sections 6 and 5, separated by a heat-conducting wall 2, communicate with each other through a water seal II. The upper part of the housing I of the installation is equipped with a heat-insulating jacket 12 made, for example, of foam or other heat-insulating material. A load 13 is placed in section 6 of the drip biofilter. The outlet pipe 14 connects the slit (filter) labyrinth 9 to the water intake well of purified water (not shown in the drawing).

The installation works as follows.

Through the inlet pipe 8, household wastewater enters the unit in portions. In section 4, solid components of the effluent precipitate, discharge occurs (knowledge and chemical-biological decomposition of the contaminants contained in the effluent. Contaminants that are lighter than water (fats, soap, etc.) float, are cut off by a partition 3 from section 5 and , gradually mineralizing, precipitate, all this occurs when there is a lack of oxygen in the metal-carbon dioxide medium, which does not lead to decay of the effluent and the formation of an unpleasant odor.

After precipitation, the clarified effluents through openings 7 in the partition 3 enter section 5, where the above processes continue and, with the subsequent receipt of new poridium, effluents are poured through a water trap II into section 6, which is a drip biofilter with a biofilm on expanded clay loading.

in section 6 of the drip biofilter, due to the presence of the ventilation tube 10 and the outlet pipe 14, connected with the slot labyrinth 9, air actively flows due to natural ventilation. At the same time, section 6 maintains the optimum temperature, which, together with the oxygen coming from the air, ensures the vital activity of microorganisms in the droplet biofilter.

Heating to the optimum temperature takes place through the heat-conducting wall 2 from the methane tank formed by the sheaths 4 and 5, where warm effluents enter and where an exothermic reaction occurs, which also contributes to the heat-insulating jacket 12.

The labyrinth 9, cleaned in section 6 droplet biofilter through a slotted filter, is directed by gravity to the outlet well through the outlet pipe 14.

Thus, the proposed compact installation works by gravity in a self-regulating manner and therefore effectively cleaning drains does not require energy-consuming mechanisms in the form of pumps, compressors, etc. devices, making it economical and environmentally friendly.
